NTSB summary
HISTORY OF FLIGHT On June 17, 2019, about 1125 eastern daylight time, an experimental Trella T-21, N450C, was substantially damaged when it was involved in an accident near Endicott, New York. The commercial pilot was fatally injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. A witness stated that the pilot's first takeoff and landing appeared normal. During the second takeoff, he witnessed the airplane climb out normally until it was just past the runway 21 threshold about 300 ft above ground level and the engine made a loud single “pop” similar to a backfire. The airplane remained in a slightly nose-high attitude as it began a left turn almost immediately following the “pop.” The turn looked to begin at a normal rate and bank angle but quickly steepened and became tighter. As the airplane's bank angle reached around 60 to 70°, the nose began to fall and the airplane spiraled to the ground. The airport manager stated that he heard a reduction in the airplane's engine power as the airplane was about 300 ft above the runway. He then watched the airplane continue toward the end of the runway, where it entered a left descending turn before disappearing behind trees (Figure 1 shows the accident site location in relation to the airport). Figure 1. Accident site location. AIRCRAFT INFORMATION The airplane was a high wing, all-metal construction, two-place airplane with twin tailbooms and a pusher engine configuration. The airplane was originally equipped with a Continental C-85-12J engine, which generated 85 horsepower (hp). As o
Probable cause
A partial loss of engine power for reasons that could not be determined, and the pilot's subsequent exceedance of the airplane's critical angle of attack during an attempted return to the runway, which resulted in an aerodynamic stall/spin at an altitude that precluded recovery.
