Dayton-Wright Brothers Airport
Aircraft Accident/Incident Report
Dayton, Ohio 45342
Thursday, April 1, 2010 12:53 EDT
NTSB Narrative Summary Released at Completion of Accident
Approximately 1 minute after takeoff, as the airplane was about 1 mile southwest of the airport, the pilot reported an engine failure to air traffic controllers and initiated a return to the airport. One witness, located about 1 mile west of the airport, reported that the sound of the engine changed abruptly; noting that the engine seemed to lose power completely. Another witness, located near the airport, observed the airplane approach from the west and turn to align with the downwind runway. During the turn, the left wingtip struck the ground and the airplane impacted short of the runway. A postimpact fire ensued. Although the pilot initiated a return to the airport, an interstate highway and an open grass area short of the runway were both potentially available for an emergency landing. A postaccident examination of the engine revealed that the No. 1 (aft) main crankshaft bearing failed due to unknown circumstances. The progressive failure of the bearing likely precipitated secondary failures of the crankcase through-bolt and the fuel pump coupling, which resulted in a complete loss of engine power.
NTSB Probable Cause Narrative
The complete loss of engine power due to failure of the No. 1 main bearing, and the secondary failure of a crankcase through-bolt and the fuel pump drive coupling. Contributing to the accident was the pilot's decision to attempt a return to the airport for a downwind forced landing, despite having an interstate highway and an open grass area short of the runway as available emergency landing sites.
