On September 21, 2020, about 1949 eastern daylight time, a Stearman E75, N1524M, was destroyed when it was involved in an accident near Honea Path, South Carolina. The private pilot and his airline transport pilot-rated student were seriously injured. The flight was conducted under the provisions of Title 14 Code of Federal Regulations Part 91.
The airplane departed and was in a continuous climb at 70 mph, at 2,500 rpm. The pilot observed a cylinder depart the engine and experienced a partial loss of engine power. A video of the event recorded the sound of the engine becoming quieter and the tachometer showed a continuous 1,000 rpm reading following the separation. The video captured the airplane maneuvering over open fields suitable for a forced landing as it descended back towards the departure airstrip. The recording ended before the airplane was destroyed by contact with trees and terrain 500 feet prior to the landing strip.
Examination of the nine-cylinder radial engine revealed a separated cylinder, with all of its associated mounting studs fractured. Three of the mounting studs displayed features consistent with fatigue, likely due to inadequate torque applied at overhaul, which was completed less than 100 aircraft hours prior to the accident.
Probable Cause: The partial loss of engine power due to the fatigue failure of an engine cylinder and the pilot's subsequent decision to overfly several suitable forced-landing sites while attempting to return to the departure airstrip.
