On July 4, 2009, about 1329 Pacific daylight time, an Aero Vodochody L-29 airplane, N97869, was substantially damaged when it impacted terrain while maneuvering near Tehachapi, California. The airplane was registered to and operated by the pilot under the provisions of Title 14 Code of Federal Regulations part 91. The commercial pilot and airline transport pilot were killed. Visual meteorological conditions prevailed and no flight plan was filed for the personal flight. The local flight originated from the Tehachapi Municipal Airport (TSP), Tehachapi, about 1300.
The accident airplane was participating in formation flight consisting of three airplanes. The lead pilot of the formation reported that after overflying the city in a trailing formation, the flight conducted a series of turns and the number two and three (accident airplane) were to join up on his left and right wing. As the flight conducted a right turn, the number two airplane joined up on the lead pilot’s left wing and the number three airplane was observed passing the lead pilot to his right. As the turn continued, the lead pilot observed the accident airplane pitch upwards and roll to the left over the formation. Witnesses located near the accident reported observing a three-jet formation overfly the area at an altitude of about 500 feet above ground level (agl). The accident airplane was observed trailing the other two airplanes. The witnesses reported that the three airplanes initiated a right turn to a northerly heading and the accident airplane made a sharp right climbing turn to join up with the other two airplanes. Subsequently, the accident airplane pitched upwards and rolled to the left over the other two airplanes, transitioning from the right side to the left side. Witnesses further reported that the accident airplane completed the roll in a nose low attitude and descended into terrain where a post-crash fire ensued. Examination of the airplane revealed no pre-impact mechanical anomalies with the engine or airframe.
Probable Cause: The pilot’s failure to maintain clearance from terrain while performing a low altitude maneuver.
