Accident Summary
A single-engine airplane impacted terrain short of the approach end of the runway during a night visual approach. The pilot, on final approach, was conducting the final checklist when he observed the airplane at an altitude of approximately 300-400 feet above ground, aligned with the glide slope as indicated by the Precision Approach Path Indicator (PAPI) lights. The airspeed was 85 knots with the landing gear extended, and the pilot believed he had set 10 degrees of flaps.
Pilot Statement
The pilot stated that the airplane began to "pancake down" and he was unsure why the airspeed had decreased. When he recognized the situation, he applied full power. The engine surged, but the airplane was too close to the ground and subsequently landed in the desert.
Witness Observation
A witness located near the approach end of the runway observed the airplane's wings rocking back and forth during the final approach, after which the airplane dropped out of the sky. The witness reported that the engine was not making unusual sounds during the approach.
Aircraft Information
According to the airplane manufacturer's approved flight manual, landings can be performed with any flap settings. For a normal landing with full flaps extended, the approach speed should be between 80 and 85 knots, with power adjusted as necessary to maintain the approach angle. For a flaps-up condition, the recommended approach speed is 95 knots.
Post-Accident Examination
Post-accident examination of the airplane revealed that the flaps were in the retracted position, and the cockpit flap selector handle was found in the up position.
