On October 6, 2007, a Cessna 150D (registration N4570U) operated by Kermeth Owens was involved in an aviation accident near Strawberry, AZ. Investigators recorded the probable cause as: The loss of engine power for an undetermined reason. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
An aircraft's engine output dropped to idle at 750 feet agl during approach. Emergency procedures failed, leading to a forced landing in rough terrain that substantially damaged the fuselage and wing. Post-accident engine examination revealed no preimpact malfunctions.
Event Description
During the approach to an airport, the aircraft descended to 750 feet above ground level. At that altitude, the engine power output reduced to idle. The pilot executed emergency procedures designed to restore engine power, but these actions did not succeed. The pilot attempted multiple procedures, yet the engine remained at idle. Consequently, the pilot conducted a forced landing on rough terrain.
Damage
The forced landing resulted in substantial damage to the fuselage and wing of the aircraft.
Post-Accident Examination
Investigators examined the engine after the incident. They observed no preimpact malfunctions that would have precluded normal engine operation. This indicated that the engine was functioning normally prior to the power loss.
