Grumman Acft Eng Cor-Schweizer G-164B N993QC accident near Lake City, Arkansas

Probable cause

The partial loss of engine power for reasons that could not be determined based on the available evidence.

NTSB analysis

The operator reported that, on initial takeoff for an aerial application flight, the engine would only produce 90-percent power. The airplane could not maintain a climb, so the pilot performed a forced landing to a road. During the landing roll, the airplane slid to the side of the road and impacted a ditch, which resulted in substantial damage to the fuselage. The engine was removed from the airplane and sent to an unknown vendor for repair. The operator subsequently went out of business, and the disposition and location of the engine could not be determined. The reason for the loss of partial engine power could not be determined.
