Grumman G 164A N7951 accident near Maysville, Oklahoma

Probable cause

The loss of engine power for reasons that could not be determined because a postaccident examination of the airframe and engine did not reveal any anomalies that would have precluded normal operation.

NTSB analysis

The commercial pilot had completed his second agricultural application flight of the day in the airplane. As he was returning to the departure airport, the engine experienced a loss of power. The pilot conducted a forced landing to a field, and the airplane subsequently nosed over and came to rest inverted.

An examination of the airframe and engine did not reveal any preimpact anomalies that would have precluded normal operation. The weather conditions at the time of the accident were conducive to serious icing only at glide power; the engine was likely operating at cruise power at the time of the power loss. The reason for the loss of engine power could not be determined.
