Amateur-built CP301 accident near Paulding, Ohio, January 17, 2020

The NTSB's narrative final · quoted from the NTSB record

The pilot reported that after takeoff, about 250 ft above ground level, the engine backfired three times and lost power. He attempted to return to the airport and completed a 180° turn toward the runway. He did not recall any events following that turn. A witness heard the engine pop and sputter and then saw the airplane fall to the ground. The airplane was fragmented into many pieces when it hit the ground. A postaccident examination did not reveal any anomalies with the engine that would have precluded normal operations. Examination of the fuel tank screen contained debris consistent with fiberglass from the fuel tank. It is likely that the fuel tank was degrading and this debris from the fuel tank clogged the fuel tank screen and resulted in a loss of engine power due to fuel starvation. The damage to the airplane and the witness statement is consistent with a stall. It is likely that during the turn back toward the runway the pilot did not maintain the proper airspeed and he exceeded the airplane’s critical angle of attack which resulted in an aerodynamic stall.
