E/AB Aircraft Safety

The Experimental/Amateur-Built aircraft category has been the fastest-growing segment of general aviation for some years. The term amateur-built suggests the aircraft was assembled by an individual instead of a factory. In fact, the FARs state that an amateur-built aircraft is one that the major portion of which has been fabricated and assembled by persons who undertook the construction project solely for their own education or recreation. The FAA requires that an amateur-built aircraft must be assembled or constructed at least 51 percent by an amateur, not including the engine(s), propeller(s) or accessories. Meanwhile, the term experimental encompasses much more than just amateur-built aircraft. Examples include those used for research and development, air racing, exhibition, etc.

Key Takeaways:

• Experimental/Amateur-Built (E/AB) aircraft are a fast-growing segment of general aviation that historically experienced disproportionately higher accident rates, particularly due to loss of control and powerplant failures, often early in an aircraft's operational life or with new owners.
• Following a 2012 NTSB safety study, collaborative efforts by the EAA, FAA, and the E/AB community have led to significant reductions in accidents and fatal accident rates.
• Crucial safety measures for E/AB aircraft include rigorous pre-flight testing, comprehensive type-specific transition training programs, and careful due diligence for individuals considering building or purchasing an E/AB.
