Incident Overview
A pilot was conducting a landing at an elevation of 6,900 feet mean sea level on the Matanuska Glacier. During the approach, while on short final, the engine lost power. The pilot attempted to restore engine power but was unsuccessful. The airplane subsequently landed hard, coming to rest approximately 500 feet short of the intended touchdown point.
Damage and Post-Landing Discovery
The airplane's fuselage sustained substantial damage from the hard landing. After the aircraft came to a stop and while securing the cockpit controls, the pilot discovered that the fuel boost pump switch was positioned in the 'high boost' setting.
Relevant Aircraft Information
The airplane was a Cessna model. According to the Cessna Pilot's Operating Handbook, if the engine-driven fuel pump switch is placed in the ON position, a fuel/air ratio considerably richer than best power is produced unless the mixture is leaned. This condition can affect engine performance.
Investigation Status
The incident is based on the pilot's report. No further details about the aircraft, registration, date, or individuals involved were provided in the source material.
