MCCURRY CHARLES P F 1 ROCKET near Sedona, AZ — 2015-03-21

Probable cause

The partial loss of engine power during final approach for reasons that could not be determined during postaccident examination of the engine.

NTSB narrative

The pilot reported that, on final approach to landing, he added power to maintain the desired glidepath, but the engine did not respond. Despite adjusting the throttle and additional troubleshooting efforts, the pilot noted no response from the engine. He reported that the engine remained running between 1,200 and 1,300 rpm. The pilot initiated a forced landing to a road about 1 mile southwest of the airport, and, during the landing roll, the airplane struck desert vegetation and then came to rest upright. Postaccident examination of the airframe and engine revealed no evidence of any mechanical malfunctions or failures that would have precluded normal operation.
