Probable cause

The fuel exhaustion induced power loss, which resulted from the pilot's inaccurate fuel consumption calculations.

Sequence of events

NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.

Loss of engine power(total) - nonmechanicalCruise - normal
Fluid,fuel - exhaustionCause
Fuel consumption calculations - inaccuratePilot in commandFactor
Forced landingDescent - emergency
In flight collision with terrain/waterLanding - flare/touchdown
Terrain condition - ditch

Analysis

The pilot stated that the fuel quantity gauge was inoperative and that he intended to refuel every hour and 45 minutes. He had flown for two hours without refueling on the preceding day. At 1,500 feet the power loss occurred. During the forced landing the pilot realized that his chosen site had uneven terrain and ditches. He was trying to fly the airplane across a ditch when the tail struck the embankment. No evidence of fuel in the wreckage was found and the successful engine test run did not reveal any mechanical malfunctions.
