A pilot experienced a loss of fuel pressure after departure, engine failure, and made an emergency landing in a muddy field. Post-accident investigation revealed the fuel selector was on an empty tank.

Introduction

A personal cross-country flight ended in an emergency landing after the engine failed shortly after departure. The pilot reported a loss of fuel pressure, which could not be restored by the auxiliary fuel pump. The flight was conducted in an airplane that was out of annual inspection.

Flight and Engine Failure

After departing for the cross-country flight, the pilot noticed that fuel pressure was dropping. He activated the auxiliary fuel pump, but it failed to restore fuel pressure. The pilot then turned the airplane to return to the departure airport. During the return, the engine failed completely.

Emergency Landing

With the engine inoperative, the pilot attempted an emergency landing. The airplane touched down in a soft, muddy farm field. The landing resulted in substantial damage to the airplane.

Post-Accident Investigation

Investigators examined the airplane after the accident. They found that the fuel selector was positioned to the right-hand fuel tank. That tank contained no visible fuel. Additionally, the airplane's annual inspection had expired.

Probable Cause

The investigation did not state a probable cause for the accident.
