Cessna 210 N9824G accident near Coalinga, California

Probable cause

A partial loss of engine power during takeoff for reasons that could not be determined, because postaccident examination revealed no mechanical malfunctions or failures that would have precluded normal operation.

NTSB analysis

The private pilot was departing in the turboprop-equipped airplane when, between 200 and 300 ft above ground level, the airplane experienced a partial loss of engine power, with no abnormal fuel indications observed. After he advanced the throttle and condition levers, the pilot realized that there was not sufficient power to maintain altitude, so he elected to make a forced landing to an open dirt field. During the approach, the airplane impacted multiple power lines before landing gear-up. A postaccident examination of the engine and fuel system did not reveal any anomalies that would have precluded normal engine operation. The reason for the partial loss of engine power was not determined.
