Introduction
In an industry that flies the most advanced technology in the world, why are we still recording our careers with greasy pens and paper?
For any Aircraft Maintenance Engineer (AME) working under the European Aviation Safety Agency (EASA) regulations, the logbook isn't just a notebook—it is your career passport. Whether you are applying for your first B1 or B2 license, adding a type rating, or moving to a new airline, your ability to prove your experience is the single most important factor in your professional progression.
However, many engineers struggle with the specific administrative requirements. Missing signatures, vague descriptions, or lost records can delay license issuance by months. In this guide, we break down the specific requirements of the EASA Part-66 logbook, common mistakes to avoid, and how to keep your records audit-proof.
What is the EASA Part-66 Logbook?
Under EASA Part-66 (specifically Appendix I to Part-66), certifying staff must demonstrate practical experience to qualify for a license. The logbook—often called the "Experience Log"—is the formal record of this experience. It serves as verifiable evidence that you have:
- Performed maintenance on operational aircraft (not just training aids).
- Gained experience across a wide range of tasks and ATA chapters.
- Worked under the supervision of qualified certifying staff who can vouch for your competence.
Unlike a personal diary, this document is a legal record that can be audited by your National Aviation Authority (NAA) at any time.
Key Requirements: What Must Be Recorded?
A simple list of dates is not sufficient for EASA compliance. To ensure your logbook is accepted by the authority, every entry must be detailed and specific. According to Part-66 Appendix I, a compliant entry typically includes:
- Date: The exact day(s) the work was performed.
- Aircraft Type & Registration: E.g., Boeing 737-800 (G-ABCD). Generic entries like "B737" are often rejected; the specific airframe matters.
- ATA Chapter: The system you worked on (e.g., ATA 27 Flight Controls, ATA 32 Landing Gear). This helps auditors ensure you have a broad spread of experience.
- Description of Work: A clear, technical summary of the task (e.g., "Replaced left inboard aileron actuator and performed functional check").
- Duration: Time spent on the task.
- Supervisor Signature & License Number: This is crucial. The certifying person must sign off that you performed the work. Without a valid signature, the experience is considered invalid.
The Experience Rules: "1-Year" vs. "3-Year"
One of the most confusing aspects for new engineers is the time requirement for license application. The rules differ based on your training path:
- Standard Path (No Type Training): You typically need 5 years of documented maintenance experience.
- With Approved Type Training: If you have completed an approved type rating course, the experience requirement can often be reduced.
Additionally, there is the Recency Rule. EASA generally requires that you have recent experience—usually within the last 3 years. If your logbook has long gaps or you haven't performed maintenance tasks for over 3 years, previous entries might not count towards a new license application without refresher training.
Common Mistakes That Delay License Applications
At AMELogbook, we review thousands of logbook entries. Here are the top reasons applications get sent back by the CAA:
Writing "General maintenance," "Weekly check," or "Inspection" is not accepted. You must be specific. Instead of "Inspection," write "Inspected MLG shock strut for leakage and checked fluid level."
An unsigned logbook entry is considered invalid. Ensure your supervisor signs entries regularly—ideally on the day of the work. Waiting months to get signatures often leads to rejected applications.
Paper logbooks are vulnerable. They get lost, damaged by oil, or left in hangars. Without a backup, you lose credit for months or years of hard work, resetting your career clock.
The Digital Solution: Accuracy & Backup
The aviation industry is modernizing. Relying solely on paper records is becoming a liability. A digital logbook ensures you never lose data and helps you generate reports instantly for the authority.
With a digital solution like AMELogbook, you can:
- Track tasks by ATA chapter automatically to ensure you meet breadth requirements.
- Calculate total experience hours in seconds.
- Store your data securely in the cloud—accessible from any device.
- Export professional PDF reports ready for Civil Aviation Authority (CAA) submission.
