NTSB summary

HISTORY OF FLIGHTOn August 20, 2023, about 1200 eastern daylight time, a Beech C23 airplane, N9360S, was substantially damaged when it was involved in an accident near Greer, South Carolina. The private pilot and the mechanic-certificated passenger were fatally injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 postmaintenance test flight after an annual inspection. A witness who lived at the fly-in community where the airplane was maintained reported that the airplane took off from runway 3 at Chandelle Airport (SC72), Greer, South Carolina. As the airplane passed his house, he heard a slight reduction in engine speed followed by a slight increase. The engine did not sputter or backfire. The airplane then turned toward the northwest and reached an altitude of about 500 ft above the ground. The witness observed that the left wing dipped twice then leveled off, and the airplane descended as it turned to a westerly heading. The airplane descended from his view behind a tree line, then he heard it impact the ground. The witness’s account of the accident flight was generally consistent with a video of the accident sequence captured by a camera from an unnamed source. The video, which was broadcast by a local news station, showed the airplane on departure. The left wing dipped slightly twice, then the right wing dipped. The airplane then developed a sink rate with the nose slightly up. Shortly before ground impact, the airplane’s nose dropped, and the left wing dipped again. The airplane collided with the ground in a slight left-wing-low attitud

Probable cause

A partial loss of engine power during the initial climb due to the formation of carburetor ice, resulting in reduced climb capability. Contributing to the accident was the pilot’s failure to maintain proper airspeed during the emergency descent, which resulted in an exceedance of the airplane’s critical angle of attack and a subsequent aerodynamic stall.

    Phase and cause come from the NTSB’s own coding of each accident, which only exists from 2008 on, so these two filters leave out 1982–2007. Cause categories are only recorded for some accidents, and early findings can change.
