Engine Power Loss During Landing on Matanuska Glacier

Casualties unknown • Chickaloon, AK, US

A pilot experienced an engine power loss while on short final for landing on the Matanuska Glacier, resulting in a hard landing and substantial damage to the aircraft.

What happened

While performing a landing at an elevation of 6,900 feet MSL on the Matanuska Glacier, the pilot of a Cessna experienced a loss of engine power during the short final phase of flight. The pilot attempted to restore power to the engine, but these efforts were unsuccessful. As a result, the aircraft landed hard approximately 500 feet short of the intended touchdown point. The impact caused substantial damage to the airplane's fuselage.

Following the landing, the pilot began securing the cockpit controls. During this process, it was discovered that the fuel boost pump switch had been left in the 'high boost' position.

Probable cause

The engine lost power because the fuel boost pump switch was set to the high boost position, which produces a fuel-to-air ratio considerably richer than best power unless the mixture is leaned.
