Aviation Maintenance Standards, Jurasdictions and Learning

The global aviation industry operates on a paradox: while the aircraft are technically identical, the “safety value” of the personnel maintaining them is governed by legal jurisdiction and regional oversight.

Training & the same course, different legal weight

If you train three engineers on the same Boeing 787 course, their utility is dictated by their License Authority.

  • FAA (USA): Operates on a “Generalist” model. An Airframe & Powerplant (A&P) license can be earned in ~18–24 months. It’s highly versatile but requires documented “supervised experience” before an engineer can sign off on specific complex systems.
  • EASA (Europe): Uses a “Specialist” model (Part-66). It takes 3–5 years of modular exams and theory. Once licensed as a B1 (Mechanical) or B2 (Avionics), the engineer is legally an “expert” with broad sign-off authority upfront.
  • The Driver: This isn’t about skill—it’s Bilateral Aviation Safety Agreements (BASA). An FAA engineer cannot legally release an EASA-registered aircraft without a specific EASA 145 approval, regardless of their training.

The “3rd Country” Labour Strategy

Major MROs (Maintenance, Repair, and Overhaul) can use 3rd Country Approvals to arbitrage labour costs.

  • How it works: Companies can open a facility in the Philippines and by obtaining an EASA Part-145 Third Country Approval, the facility can use local technicians (paid at local rates) to maintain European-registered fleets; noting the training must be approved by EASA and is often to EASA standards on EASA certificates with a local license.

Safety Records: The Geographic Gap (2025 Data)

Safety is not a global constant; it is a reflection of local oversight rigor and infrastructure.

Region                    Accident Rate / 1M flights  Trend (2025)

Europe (EASA)       1.02              Gold standard; focuses on “Just Culture.”

USA (FAA)              1.20              High volume, very low fatality risk (near zero).

Asia-Pacific             1.62              Rising due to high-growth complexity and turbulence.

Africa                       9.54              Improving but hindered by aging fleets and infrastructure.

Does one country or license stand out? EASA licenses have large scope for use and high demand as do FAA so does it matter where the license was issued; does the country matter for a EASA license? Some licenses changed values based on demand such as the UK CAA once being sought, is now limited to its usage being confined largely to the UK.
