NTSB summary
HISTORY OF FLIGHTOn June 14, 2015, about 1127 central daylight time, a Grumman American Aviation Corporation AA-5 single-engine airplane, N6552L, was substantially damaged when it impacted terrain shortly after takeoff from Gillespie County Airport (T82), Fredericksburg, Texas. The private pilot sustained serious injuries, and his passenger was fatally injured. The airplane was registered to a private individual and operated by the pilot under the provisions of 14 Code of Federal Regulations (CFR) Part 91 without a flight plan. Day visual meteorological conditions prevailed for the local flight, which was originating at the time of the accident. On the morning of the accident, the pilot and his aviation mechanic were at the airport to complete an annual inspection of the airplane. Although the pilot was an automotive mechanic, he reported that he did not participate significantly during the annual inspection. He recalled that the mechanic removed several inspection panels to observe the flight control system; verified operation of an avionic device that was installed in the rear fuselage; completed a compression check of each engine cylinder; removed, inspected, and replaced some spark plugs; and drained/replaced the engine oil. Additionally, the pilot recalled that the mechanic collected a fuel sample from at least one drain on the left wing. The pilot stated that the airplane had four fuel drains (two per wing); however, he could not recall if the mechanic had obtained a fuel sample from all four drains during the annual inspection. Additionally, he did not recall if the
Probable cause
The pilot's failure to maintain adequate airspeed following a partial loss of engine power during initial climb, which resulted in the airplane exceeding its critical angle of attack and experiencing an aerodynamic stall. Also causal was the mechanic's inadequate inspection of the airplane fuel system, which resulted in the partial loss of engine power due to fuel contamination.
