Piper PA-28-161 N706GS accident near Buffalo, New York

Probable cause

A total loss of engine power for reasons that could not be determined because a postaccident examination of the airframe and engine test run revealed no mechanical malfunctions or failures that would have precluded normal operation.

NTSB analysis

The flight instructor was providing an introductory flight to the passengers. Following an uneventful preflight inspection and engine run-up, the flight instructor prepared to depart. An air traffic controller offered, and the instructor accepted, an intersection takeoff that reduced the runway's 8,800-ft available takeoff length by about half. Shortly after rotation, the engine briefly lost all power. As the flight instructor attempted to troubleshoot the problem, the engine power was briefly restored, and she then decided to return to the airport and land. As she turned the airplane back toward the runway, the engine again lost total power. As the airplane's airspeed decreased, she chose to perform a forced landing to a parking lot, during which the airplane was substantially damaged.

A postaccident engine test run revealed no anomalies, and examination of the airframe and fuel system revealed no mechanical malfunctions or failures. The reason for the loss of engine power could not be determined.
