An amphibious airplane suffered an engine failure at about 300 feet above ground on short final, leading to a landing in soft mud with wheels extended and subsequent overturn. No injuries reported.

Incident Overview

An amphibious airplane was on short final approach to land on a runway when the engine quit approximately 300 feet above the ground. The aircraft touched down in soft mud with its landing gear extended and subsequently flipped over.

Postaccident Examination

Following the accident, investigators examined the aircraft and found fuel present in both wing tanks. The engine-driven fuel pump was removed and subjected to bench testing, during which it failed to pump fuel. Additionally, when primed and operated, the pump drew air into the system.

Fuel Pump Disassembly

The fuel pump was disassembled, but no blockages, damaged seals, or other sources of the air leak were identified. The exact cause of the pump's failure to deliver fuel remains undetermined.

Conclusion

The accident occurred when the engine quit during the landing approach, forcing a landing in soft mud that caused the aircraft to overturn. The loss of engine power was attributed to the malfunction of the engine-driven fuel pump.
