1. FINDINGS AND INVESTIGATIONS EXPERIMENTAL AIRCRAFT ACCIDENTS

2. HOMEBUILT/AMATEUR BUILT AIRCRAFT Unique in nature-customized to the owner Builders have more leeway to modify designs and select materials, unlike standard type certificated aircraft Account for approximately 11% of all general aviation aircraft

3. EXPERIMENTAL AIRCRAFT (FAA) Aircraft does not have type certificate or does not conform to its type certificate. Amateur built: major portion is fabricated and assembled by persons for their own recreation or education Kit built: assembled by a person from a kit, which was manufactured by a production certificate holder, without supervision and quality control of the production certificate holder Light sport aircraft Special airworthiness certificates may be issued for research and development, showing compliance with regulations, crew training, exhibition, air racing, and market surveys

4. 2012 NTSB STUDY In 2011, there were 224 experimental amateur built (EAB) aircraft accidents in the US; 54 were fatal 10 of 103 EAB aircraft accidents involving aircraft built by the owner, crashed on their first flight Of the 125 EAB accidents involving a purchased aircraft, 14 new owners crashed on their first flight Most involved experienced pilots Powerplant failures and loss of control in flight were the most common causes (NTSB and ICAO). The study resulted in 16 recommendations to the FAA and Experimental Aircraft Association (EAA)

5. NTSB FINDINGS EAB aircraft account for a disproportionate number of total accidents and fatal accidents as compared to similar non-EAB aircraft Powerplant and loss of control in flight are the most common occurrences (NTSB and ICAO) EAB aircraft accidents disproportionately crash early in their operational life, as compared to similar non-EAB aircraft EAB pilots have a similar or higher level of experience as compared to similar non-EAB pilots engaged in similar general aviation operations, but had significantly less experience in the aircraft type than did non-EAB pilots The following slides are sourced from the NTSB study: http://www.ntsb.gov/safety/safety- studies/Pages/SS1201.aspx

9. KEY ISSUES IDENTIFIED Not all builders perform a thorough flight test program or create a detailed flight manual during Phase 1 testing Functional testing of fuel systems could identify design deficiencies, leaks, and malfunctions prior to flight Availability and quality of transition training Guidance for purchasers of used EAB aircraft FAA and NTSB data limitations 16 recommendations in total, 12 to the FAA and 4 to EAA Included more detailed documentation requirements for initial certification, verification of Phase 1 testing, improved training and support, use of recorded flight testing data, and improved registry documentation

11. INVESTIGATIONS Experimental aircraft are considered a segment of general aviation and follow the same protocols of accident investigation, The FAA will be on scene for experimental aircraft accidents and will conduct their report. Unless there is a fatality or it is a high profile experimental aircraft crash, such as the John Denver crash, the NTSB may not be on scene and may rely on FAA findings. If the pilot survived, the NTSB will still send that individual a Form 6120.5. Regardless of who does the field investigation, the NTSB will determine cause and publish their findings and recommendations.
