The Gold Standard of Education | EASA Part-66 Basic Knowledge Records and Checking the Ten-Year Application Window

An older examination record can create a surprisingly difficult planning problem. You passed the module, kept the certificate and continued learning. Years later, an application asks a different question: how does that individual examination fit the requirements applying to this licence route at the time of application?

For EASA Part-66 basic knowledge, check each module examination against the intended application date, rather than using the date of your last pass or the date a certificate was printed. Point 66.A.25(c) sets a ten-year window and identifies an exception for examinations already passed as part of another licence category where the licence has been issued. Older examinations may be considered through the competent authority’s examination-credit process under 66.A.25(d); do not treat that possibility as an approved credit decision.

This guide explains the education-record task: assembling dates, distinguishing evidence and asking a precise question. It is not a complete licensing determination or aircraft maintenance instruction. Primary sources were checked on 23 October 2026. All people, dates and document labels used in the cases are invented, and the examples deliberately avoid deciding an exact anniversary boundary for an actual applicant.

Find your next learning step

CHAPTER 1 OF 15 · Locate the evidence clock

Identify the application before counting years

Back to chapter index

Start with the route, authority and intended application. A record can be relevant to an initial licence application, an addition to an existing licence or another process. If those situations are merged into one folder labelled “Part-66,” the wrong date rule or evidence assumption can enter the plan before anyone performs a calculation.

Write a short description: “I am investigating an initial B1.1 application to the identified competent authority, with an intended submission period.” This is an example of a useful question, not a finding that a particular learner is eligible to apply there. If the authority has not been established, that remains the first enquiry.

EASA’s B1/B2 licence-route explanation distinguishes basic knowledge and basic experience from the requirements associated with an aircraft type rating. It directs applicants to the applicable requirements and the competent authority. A folder of module passes therefore cannot by itself establish completion of the entire professional route.

Keep your knowledge review narrow enough to complete. You are checking whether the module evidence can support the intended application and which questions remain. Other requirements should be tracked separately, with their own sources and responsible decision-makers. A useful record system helps those enquiries meet without pretending they are one test.

This sits within the Education parent’s concern with learning that transfers into life. Understanding a rule is useful when you can apply it to the correct event, preserve the evidence and recognise the point where an authorised decision is needed.

For the broader educational setting, education and aviation capability examines how technical understanding, continuing learning and disciplined documentation contribute to an aviation workforce. This article develops one narrower learner task within that setting: keeping basic knowledge evidence understandable across a long application timeline.

CHAPTER 2 OF 15 · Locate the evidence clock

Read the rule at the level of an individual module

Back to chapter index

The relevant EASA Easy Access Rules, point 66.A.25 place the ten-year requirement on each individual module examination. That is the key mechanism for a learner whose passes span several years. A recent pass does not make every earlier examination recent.

Imagine a set of books borrowed on different dates. Returning to the library for another book does not rewrite the date attached to the first borrowing. The analogy helps explain separate records, but it does not supply the licensing rule. The rule comes from Part-66, and the relevant reference event is the application rather than an event chosen for convenience.

Now inspect how people speak about their study. “I finished my modules in 2024” may be a useful summary of the final achievement. It is not a complete account of when the examinations were passed. “My certificate is from 2024” may describe its issue date while concealing a much earlier examination date. Those statements need supporting detail before they can answer the time question.

Use one row per module examination in your working record. Preserve the module identity, relevant scope, actual pass date and the document supporting that date. Do not invent a common date for an entire set merely because the certificates arrived together. If a date is unclear, mark it for clarification with the issuer or authority.

Once the rows are visible, sort them from oldest to newest. The oldest dates help you identify the enquiries that could affect the timetable. Sorting is a planning aid, not a substitute for checking every applicable module or any approved credit evidence.

CHAPTER 3 OF 15 · Locate the evidence clock

Separate the examination date from other document dates

Back to chapter index

A document can carry several legitimate dates. It may record an examination, the issue of a certificate, a corrected spelling or a later replacement copy. Each date describes an event. Your first task is to identify which event the date represents before using it in a time calculation.

Consider an invented certificate issued on 12 March 2020 for an examination passed on 8 February 2020. Later, the issuer replaces a damaged copy on 15 June 2026. The replacement date does not, by itself, establish that the examination was retaken in 2026. A planning record using the newest visible date would misdescribe the learning history.

Keep both the original evidence and any later clarification where available. If the replacement contains an amended field, preserve the issuer’s explanation of what changed. Do not alter the document yourself to make the dates look consistent. Your index can explain the sequence without becoming a second, unofficial certificate.

Ask a precise question when the record is ambiguous: “This document shows these dates; which is the examination pass date represented by the certificate?” Attach the relevant document through the organisation’s approved route. A question about one unclear field is easier to resolve than a broad request asking whether your entire history is valid.

This distinction transfers beyond aviation. The existing guide to credit currency for returning learners discusses academic recognition and its own clocks. It remains the owner of that wider university question. Here, the scope is the module-level evidence used for Part-66 basic knowledge.

CHAPTER 4 OF 15 · Work dates and decisions

Work backwards from a proposed application date

Back to chapter index

Use an original timeline with a proposed application on 1 October 2026. A fictional learner has one module examination passed on 15 September 2015 and another passed on 3 November 2016. The first lies more than ten years before the proposed application. The second lies less than ten years before it.

That comparison identifies a question about the older examination. It does not establish that every other requirement is satisfied, and it does not decide whether credits have been granted. The next step is to inspect the actual evidence and applicable route, including any authority-approved credit report. Keep the arithmetic conclusion smaller than the final eligibility conclusion.

Now add a pass on 20 August 2025. Does that date restart the window for the September 2015 examination? No. The individual dates remain distinct. The recent pass can be recorded accurately without being used to refresh another module’s history.

For practice, draw a line from each examination date to the same proposed application date. This makes the comparison visible and helps expose a common mistake: comparing every examination with the latest examination instead. The latest pass is an achievement, but it is not the application event named in the rule.

Use exact dates in an actual enquiry and ask the authority about boundary treatment if necessary. These illustrations use clearly separated dates so the educational mechanism remains visible. Do not turn a rough calculation into a promise that submitting at the last possible moment will be accepted or processed as intended.

CHAPTER 5 OF 15 · Work dates and decisions

Recalculate when the application moves

Back to chapter index

An application date is often provisional during planning. Evidence may still need clarification, another requirement may remain incomplete or the learner’s circumstances may change. A timeline checked against one intended date needs review when that date moves. The documents may be unchanged while their relationship to the application changes.

Suppose a fictional learner plans to apply on 1 October 2026 with an examination passed on 4 November 2016. The examination is then less than ten years old. The plan later moves to 10 December 2026, when that examination is more than ten years old. The later application creates a new timing enquiry even though the learner has done nothing to alter the original result.

The repair is to update the proposed date in the working record and recheck every relevant row. Do not merely edit the date at the top while leaving the earlier assessment of the rows untouched. Keep a note showing which reference date was used for each review so that an old worksheet does not look like a current conclusion.

This is where a simple record can outperform a vague memory of being “within the window.” The record shows what was checked, against which date and with what unresolved conditions. It also helps a training adviser identify the earliest issue needing clarification.

Avoid building a plan around an unconfirmed last-day strategy. Ask about the actual application procedure, required completeness and relevant reference event early enough to act on the answer. The point is to protect a coherent learning and evidence route, rather than to gamble on the narrowest possible interpretation of a boundary.

CHAPTER 6 OF 15 · Work dates and decisions

Distinguish older examinations from granted credits

Back to chapter index

An older examination record and an approved examination credit are different forms of evidence. Point 66.A.25(d) allows an application to the competent authority for full or partial credits in specified circumstances and refers to an authority-approved examination credit report. The possibility of applying is not the same as a favourable decision already made.

Imagine three folders. One contains a certificate for an older examination. A second contains an enquiry asking about credits. A third contains the actual decision and its supporting reference. The folders may describe successive stages of one process, but they do not have the same status. Calling all three “credits” would hide the decision still needed.

Use explicit labels in a personal index: older examination evidence held; credit enquiry submitted; decision pending; or credit decision received with stated scope. These are suggested working labels, not official form fields. Retain the authority’s own terminology in the actual record and avoid translating a conditional reply into unconditional approval.

If a credit report exists, check what it actually covers. Which knowledge requirements, route and conditions are addressed? Is the record complete and applicable to the question now being asked? Do not infer that a decision about one item automatically covers every module or a later, different application.

When the position remains unresolved, ask what further evidence or assessment is required. Do not assume either that all earlier work must be repeated or that nothing needs updating. Both shortcuts skip the authority’s role and can send a learner towards unnecessary expenditure or an incomplete application.

Read a partial decision at its actual scope

In an invented teaching case, a learner has records labelled A, B and C. An authority’s response addresses A and B, while requesting more evidence for C. The learner’s index should preserve those different states. A heading saying “credits approved” for the whole folder would overstate the response even if it accurately described two of the three items.

The same restraint applies when a decision contains conditions. Read the complete record, including what evidence it refers to and what remains outstanding. Do not copy only the favourable sentence into the planning summary. If a condition is unclear, ask about that condition directly and retain the explanation alongside the original decision.

Now suppose the learner later investigates a different route. The existing decision remains part of the history, but its applicability to the new question needs checking. Do not quietly expand its scope in a personal worksheet. A reliable index carries the decision’s limits forward with its result. That makes it easier for the next reviewer to understand what has already been settled and what still needs consideration.

CHAPTER 7 OF 15 · Inspect the record

Handle the issued-licence exception carefully

Back to chapter index

The exception in 66.A.25(c) concerns module examinations already passed as part of another licence category where the licence has already been issued. It is a specific condition, not a general statement that every experienced learner’s old examinations are outside the time requirement. The Czech CAA’s current Part-66 FAQ also explains the individual-module rule, credits and this exception.

For an illustrative learner holding an issued licence, the sensible next action is to gather that licence record and the examination evidence relevant to the proposed addition. State which category is already held and which is being investigated. Ask the competent authority to clarify how the existing record applies, rather than privately marking every old row as exempt.

For a learner who has passed examinations but has not had a licence issued, the words “already issued” cannot simply be ignored. Examination completion and licence issue are different events. A folder containing all passes may still be at an earlier stage than the exception describes.

Do not infer the required examination differences for a new category from module names alone. The applicable category, level and requirements matter. Your record should make those questions visible for the authority or properly qualified adviser, rather than trying to create a universal cross-category conversion table.

The educational lesson is about conditional reasoning. Find every condition in the exception, match each to actual evidence and keep any unmatched condition unresolved. This approach avoids both overlooking a relevant exception and claiming one before the record supports it.

CHAPTER 8 OF 15 · Inspect the record

Build an evidence index that another person can inspect

Back to chapter index

An index should make the original evidence easy to find. It should not impersonate an official decision. Use clear document references, accurate dates and a visible status field. Avoid a single green tick called “valid” when several different questions remain inside it.

Working fieldWhat to recordWhat it cannot establish alone
Application being investigatedAuthority, route and intended dateEligibility or acceptance
Module evidenceIdentity, scope, pass date and issuer referenceCompletion of the whole route
Later document eventReplacement or clarification with its reasonA new examination pass
Credit recordActual decision reference, coverage and conditionsApproval of unmentioned requirements
Original personal evidence-index template; not EASA Form 19 or an authority checklist.

This is an original organisational template, not EASA Form 19 or a prescribed authority checklist. Adapt your personal index to the evidence you hold while following the actual submission instructions. Do not send a private spreadsheet as though it replaces the certificates or decision records requested by the authority.

Include a field for the source of each fact. “Pass date from certificate” is more useful than an unexplained date copied from a recollection. “Scope awaiting issuer clarification” is more honest than an inferred category that happens to make the plan look complete.

Keep a concise enquiry log too. Record the question, organisation, date and reply reference. If a reply is preliminary or conditional, preserve that wording. The log helps you continue a conversation accurately when staff change or when several related questions are being handled separately.

Reconcile the index with the documents before relying on it

After building the index, check it in both directions. Choose a row and locate the document supporting every important field. Then choose a document and find its corresponding row. The first check reveals unsupported entries; the second reveals evidence that was received but never incorporated. Neither check requires changing the original evidence.

For example, a learner may copy the date correctly but attach the reference for a different module. Sorting the spreadsheet will not reveal that mismatch. Reading the row back against the actual document will. Another learner may retain two copies of the same record and accidentally count them as two distinct examinations. A document reference and a note explaining the duplicate can prevent the confusion.

Keep a separate note for unresolved identity or scope questions instead of inserting a guessed value. The purpose is not to produce a visually complete sheet at all costs. It is to make every populated field traceable and every important gap visible. A modest, accurate index is more useful than an elaborate one whose apparent precision depends on assumptions nobody has checked.

CHAPTER 9 OF 15 · Inspect the record

Investigate a missing or contradictory record

Back to chapter index

A missing certificate is a documentation problem before it is evidence that the examination was never passed. A certificate with an unclear field is an ambiguity before it is a licence decision. Name the immediate problem precisely so that the next action addresses it.

Suppose a fictional learner has a personal study diary recording a pass but cannot find the official document. The diary can help identify the event for an enquiry. It should not be promoted into an official certificate. Contact the issuer through its actual records process and ask what evidence can be provided or clarified.

Now suppose two copies show different dates. Preserve both and ask the issuer which date represents which event. Do not select the later date because it is more convenient for the application window. A favourable-looking inconsistency needs explanation just as much as an unfavourable one.

If names or identifiers differ, gather the evidence explaining the change and follow the authority’s instructions. Do not silently edit documents. An accurate trail can explain a genuine change without obscuring the identity of the original record. Share only the documents necessary through an appropriate channel.

Use the broader distinction developed in Observed, Inferred, Unknown. “The copy shows two dates” is an observation. “The examination was retaken” is an inference that may be unsupported. “Which event each date represents” is the question to resolve before the timetable is recalculated.

CHAPTER 10 OF 15 · Plan the next action

Separate formal evidence from current understanding

Back to chapter index

A date check concerns the use of evidence within a particular application. It does not measure everything the learner remembers or understands. Someone can retain strong knowledge from older study while needing a formal credit decision. Someone else can hold recent evidence yet need to rebuild a concept before using it competently.

Keep two parallel learning questions. What evidence is required for this route? What understanding needs refreshing for the next stage of education or supervised professional development? Answering the second does not replace the first, but it prevents the administrative review from becoming the whole learning plan.

For an original study check, ask the learner to explain a concept from the relevant module in plain language, identify the assumptions in a supplied example and describe what would change if one assumption changed. Use suitable educational materials and qualified support. This article supplies no operational maintenance procedure or authorisation to perform work.

If the explanation breaks down, identify the earliest unstable relationship. Is the term unclear, the concept forgotten or the application unfamiliar? The mathematics diagnosis guide develops this kind of distinction in another subject. The transferable habit is choosing a repair from evidence rather than from the age of the certificate alone.

Record the learning repair separately from the authority’s response. “Refreshed this topic with a teacher” is a useful educational statement. It should not be presented as “credit granted” or “requirement satisfied” unless the actual authorised decision supports that wording.

CHAPTER 11 OF 15 · Plan the next action

Ask a question the competent authority can resolve

Back to chapter index

A broad message saying “Are my modules still valid?” may force the recipient to ask for every important detail. A better enquiry identifies the intended route, the authority, the relevant examination records and the precise uncertainty. This gives the conversation a useful starting point without attempting to dictate its outcome.

For example: “I am investigating an initial application in this category. My attached record identifies the module examinations and pass dates. One examination is more than ten years before the intended application period. Please confirm the applicable process for considering basic knowledge credits and the evidence required.” Replace every field with accurate facts before sending any real enquiry.

If you already hold a licence, state that separately and identify the proposed addition. If a credit report exists, provide its reference and ask about its actual relevance. If the application date is provisional, say so. These facts can materially change the question, and concealing them makes a confident answer less useful.

Ask about unresolved dates explicitly. Which event does the authority use for the application reference in your procedure? What must accompany the application? What further clarification is required for a particular certificate? Do not assume that another authority’s administrative instructions automatically apply to yours.

After receiving a reply, write a short summary distinguishing confirmed points, conditions and remaining actions. Compare it with the actual reply before acting. If the summary says more than the source, revise the summary. A clear record helps an adviser support you without needing to reconstruct an entire email history from memory.

Turn a broad reply into the next precise question

An answer may direct you to a general process without deciding your individual records. That can still be useful. Identify what the reply establishes, then prepare the evidence needed for the next stage. Do not interpret a link to a credit procedure as a decision granting credits, or an invitation to submit documents as confirmation that they will be accepted.

If a question remains unanswered, keep the follow-up focused. For instance: “Thank you for identifying the procedure. Please clarify which document is needed to establish the pass date for this listed module.” This narrows the unresolved issue without repeating the entire history. Use the actual authority’s communication route and keep the response with the relevant record.

The learner should be able to explain the next action in one sentence: obtain a missing issuer clarification, submit the requested evidence or wait for a specified decision. When the action is still “find out whether everything is okay,” the question probably needs further separation. Clear enquiries help turn uncertainty into a sequence that can be completed and reviewed.

Previous chapter · Chapter index · Next chapter

CHAPTER 12 OF 15 · Plan the next action

Compare complete next steps before paying for more study

Back to chapter index

An older examination can lead a learner to purchase a new course immediately. Sometimes further study or examination may form part of the route. But the choice should follow the actual evidence and authority process, rather than a general fear that every previous achievement has disappeared.

Compare the available next actions by what each resolves. Obtaining a replacement document resolves missing evidence. Seeking a credit decision addresses formal consideration of earlier knowledge. Refreshing a topic addresses present understanding. Booking an examination has its own consequences. These actions may eventually belong together, but they are not interchangeable repairs.

Before paying, ask the provider what the proposed course actually delivers and which claims depend on an authority’s decision. Keep approved basic training, examination preparation and a personal refresher distinct. Do not infer the effect on other licence requirements from the attractive wording of a course title.

A family member can help organise dates, listen to the learner’s explanation and protect study time. A teacher can diagnose understanding and suggest appropriate educational work. The competent authority decides matters within its remit. Giving each person a clear role prevents supportive advice from being mistaken for formal approval.

The existing ACCA guide to preserving experience evidence during a role change concerns a different qualification and different rules. Its useful connection is the discipline of preserving actual evidence before a transition makes it harder to retrieve. It does not supply a Part-66 sign-off process.

Previous chapter · Chapter index · Next chapter

CHAPTER 13 OF 15 · Check the changed route

Test the method with a changed timeline

Back to chapter index

Try this original exercise before reading the discussion. A learner has three fictional module examinations: 10 January 2015, 12 May 2019 and 6 June 2024. A replacement copy for the first was issued in September 2026. The learner is investigating an initial application in November 2026 and has no credit decision recorded. What should the working index show?

The January 2015 examination is more than ten years before the intended application period. The replacement copy does not establish a new examination in 2026. The later passes remain separately dated. The record should identify the older examination and the unresolved credit question, without declaring the whole application accepted or rejected.

Now change the facts. The learner produces an actual authority-approved credit report. The next action is to read its scope, conditions and relevance to the intended application, not merely change the spreadsheet’s colour. A decision record is meaningful because of what it actually decides.

Change the case again. The learner already holds an issued licence in another category and is investigating an addition. The exception and the applicable examination differences now need to be considered against the actual licence and module records. The initial-application explanation cannot be copied unchanged into this different route.

Finally, suppose the intended application moves by several months. Recalculate the relevant relationships using the new reference date and retain the earlier planning version. If you can explain what changed and what remained the same in each variation, you understand the record mechanism. If every answer remains “use the newest certificate,” return to the distinction between events.

CHAPTER 14 OF 15 · Check the changed route

Resolve common questions without overstating the result

Back to chapter index

Does a recent module pass refresh all earlier passes?

No. The rule applies to individual module examinations. Keep the actual dates separate. The date of the last examination can describe when a set was completed, but it does not replace every individual pass date for this enquiry.

Does an older examination mean the original achievement never happened?

No. Preserve the evidence of what was passed. The question concerns how it can support a present application, including whether the authority’s credit process is relevant. Avoid turning a scoped timing issue into a statement that the learner’s entire education has been erased.

Can I award myself credits after comparing syllabuses?

No. Your comparison can help organise an enquiry, but it is not an authority-approved examination credit report. Keep your educational analysis and the actual decision record distinguishable. The authority may require evidence and consideration that your private comparison cannot supply.

Do the examples decide an exact ten-year anniversary?

No. They use clearly separated dates to teach the relationship. For a real boundary question, provide exact evidence and ask the competent authority about the applicable treatment and procedure. Do not rely on approximate years or a privately chosen application event.

Does this decide a Singapore or UK licensing route?

No. This article focuses on the cited EASA Part-66 provisions. Identify the actual authority and framework for your intended route. A similar name or related training history does not establish that another jurisdiction’s requirements or recognition decisions are identical.

Previous chapter · Chapter index · Next chapter

CHAPTER 15 OF 15 · Check the changed route

Keep the source boundary and finish one useful action

Back to chapter index

The main sources are EASA’s Easy Access Rules at 66.A.25, the Czech CAA Part-66 FAQ and EASA’s B1/B2 route explanation. The Easy Access page identifies its September 2025 revision; the CAA’s current guidance was also checked on 23 October 2026. Consult the current applicable requirements and competent authority for an actual application.

The source-based points are the individual-module window, the stated issued-licence exception, the examination-credit route and the distinction between knowledge and other requirements. The indexes, timelines, enquiry wording and learning checks are original educational analysis. They are intended to make a conversation accurate, not to replace a licensing assessment.

Your next action is to choose one real record and identify its events. Which date is the examination pass? Which date is merely a later document event? Which application are you investigating? Which decision, if any, has actually been made about credits? Once those answers are visible, the remaining uncertainty becomes easier to ask about.

An orderly evidence trail cannot guarantee an outcome. It can protect the truth of the learner’s history and make the next decision more informed. That is a worthwhile educational achievement in its own right: understanding both what the record shows and what still needs an authorised answer.

Keep that distinction visible when explaining the plan to someone helping you.
