AME Apprentice Logbook Guide: Hours, Tasks, and TC Approval
Your apprentice logbook is the single most important document in your AME licensing journey. It is the official record that Transport Canada uses to verify your practical experience before issuing your license. A well-organized logbook can mean the difference between a smooth approval process and months of delays. Here is everything you need to know.

Why Your Logbook Matters
Transport Canada requires all AME apprentices to document their practical experience in a logbook before they can be issued a license. This logbook serves as proof that you have completed the minimum experience requirements outlined in CAR Standard 566. Without a properly maintained logbook, Transport Canada will not approve your application — regardless of how many years you have worked in the industry.
The logbook is not just an administrative formality. It is also a tool that helps you track your own progress, identify gaps in your experience, and ensure that you are getting exposure to all the task areas required for your specific license category (M, E, or S). Many apprentices discover halfway through their 48-month experience period that they have been neglecting certain task categories, forcing them to seek out additional work in those areas.
Experience Requirements: 48 Months of Practical Work
The baseline experience requirement for all AME license categories is 48 months of practical maintenance experience. However, this can be reduced if you have completed an approved training program at a Transport Canada-designated training organization. Graduates of approved programs typically need only 12 to 24 months of additional practical experience, depending on the program length and the license category.
Your experience must be gained while working under the direct supervision of a licensed AME, and it must involve the maintenance of aircraft or aircraft components. The 48-month period is calculated in calendar months, not working hours — meaning part-time or seasonal work counts proportionally less. Transport Canada expects a minimum of 1,600 hours of hands-on maintenance work per year of experience claimed.
Task Categories: What You Need to Log
Transport Canada's logbook requirements are organized by task categories that vary depending on your license category. For an AME M (Airframe and Powerplant) license, the main task categories include:
- Airframe Structures — Sheet metal repair, composite repairs, structural inspection, corrosion control, and major/minor repairs per the SRM.
- Powerplant Systems — Engine removal and installation, component replacement, troubleshooting, run-up and test procedures, and propeller maintenance.
- Mechanical Systems — Landing gear, flight controls, hydraulic and pneumatic systems, environmental control systems, and fuel systems.
- Electrical Systems — Wiring repair, component testing, battery maintenance, and system troubleshooting.
- Avionics Systems — Navigation and communication equipment, instrument systems, and autopilot testing.
- Maintenance Management — Maintenance record entries, technical log endorsements, and work order documentation.
For each task you log, you should include the date, aircraft type, component part number and serial number (where applicable), a detailed description of the work performed, the CAR or Standard reference, and the name and license number of the supervising AME.
How Many Tasks Do You Need?
Transport Canada does not specify an exact number of tasks — but they do require "sufficient variety and depth" across all categories. Most successful M license applicants log between 200 and 400 individual tasks across their apprenticeship. The key is not just quantity but coverage: you need to demonstrate competence across the entire scope of work for your license category.
A common mistake is logging the same type of task repeatedly — for example, 100 oil changes — without getting exposure to other categories like structural repairs or systems troubleshooting. Transport Canada inspectors look for breadth as much as depth. If your logbook shows that you have only worked on one type of aircraft or one type of task, you may be asked to get additional experience before your license is approved.
Logbook Formats: Paper vs. Digital
Transport Canada accepts both paper and digital logbooks, as long as they contain the required information and can be verified. Paper logbooks are traditional and still widely used, but digital logbooks offer significant advantages: automatic backups, easier searching, the ability to generate reports, and built-in compliance checks.
Whichever format you choose, ensure that your logbook entries are made promptly — ideally within a few days of completing the work. Entries that are logged weeks or months after the fact are harder to verify and may raise questions during the TC audit. Each entry should be signed by both you and your supervising AME.
The TC Approval Process
When you have completed your experience requirements and passed all five written exams, you submit your logbook to Transport Canada for review. The review process typically takes 4 to 8 weeks, depending on the regional office workload. A TC inspector will go through your logbook entry by entry, verifying:
- That all entries are properly signed and dated by you and your supervising AME.
- That you have sufficient variety across all required task categories.
- That the total experience period meets the minimum requirement (48 months or adjusted period for approved school graduates).
- That the work was performed on aircraft or components relevant to your license category.
If the inspector finds issues — missing signatures, insufficient variety, or unverifiable entries — they will send you a deficiency letter explaining what needs to be corrected. Addressing these deficiencies can take anywhere from a few weeks to several months, depending on the nature of the issue. This is why keeping your logbook organized from day one is so important.
Common Logbook Mistakes to Avoid
Based on feedback from TC inspectors and experienced AMEs, here are the most common logbook errors that cause approval delays:
- Missing signatures — Every entry needs both the apprentice's and the supervisor's signature. A single missing signature on a single entry can hold up the entire review.
- Vague task descriptions — "Performed maintenance on Cessna 172" is not sufficient. Describe exactly what you did: "Removed and replaced No. 1 cylinder, performed compression check, and completed run-up test per Cessna maintenance manual Chapter 71."
- No CAR or Standard references — Include the applicable regulation or standard for each task (e.g., CAR 571, Standard 573, or the applicable AMM reference).
- Too much repetition — 100 similar tire changes do not demonstrate breadth. Seek out diverse tasks early in your apprenticeship.
- Illegible entries (paper logbooks) — If the inspector cannot read it, it does not count. Consider switching to a digital logbook if your handwriting is difficult to read.
- Backdating entries — This is a serious offense that can result in your application being rejected outright. Always log entries promptly and accurately.
Tips for a Smooth Approval
Here are practical strategies that will help you avoid delays when your logbook is reviewed:
- Start organized. Set up your logbook format on day one of your apprenticeship. Use consistent naming conventions, task categories, and reference formats throughout.
- Review quarterly. Every three months, go through your logbook and identify any task categories that you are neglecting. Use this review to guide conversations with your supervisor about the types of work you need.
- Get your supervisor involved early. Make sure your supervising AME understands the logbook requirements and is willing to review your entries regularly. Some AMEs prefer to review entries weekly rather than letting them pile up.
- Keep supporting documents. Retain copies of work orders, job cards, and maintenance records that correspond to your logbook entries. While you do not need to submit these with your application, having them available can resolve questions quickly if the inspector asks for verification.
- Use a digital logbook tool. Digital platforms often include built-in verification features that help prevent the common mistakes listed above. Some also allow your supervisor to sign entries electronically, eliminating the problem of lost or forgotten signatures.
Preparing for Your AME Exams While Logging Hours
One of the best things you can do as an apprentice is to study for your AME written exams while you are logging your practical hours. The material in the exams — especially the Airframe, Powerplant, and Standards exams — directly relates to the work you are doing every day. Studying and working simultaneously reinforces both your theoretical knowledge and your practical skills.
Sky Licence is designed to fit around your apprenticeship schedule. Our platform's adaptive learning algorithms identify your weak areas and focus your study time where it is most needed, so you can prepare for exams efficiently without sacrificing time on the hangar floor. Many of our users pass all five written exams before completing their 48-month experience requirement, allowing them to move directly to the oral and practical exam as soon as their logbook is approved.
