Terrain condition - ditchFactor

Analysis

During descent for landing, with both engines being fed from the right main fuel tank, a loss of power occurred due to fuel exhaustion. A forced landing was made on a wheat field and during landing rollout the aircraft struck a ditch. Investigation revealed no fuel remaining on board in either the aux tanks or the main tanks. However, with the master switch on, the right main fuel gauge read more than 1/4 tank remaining.
