Probable cause

The pilot’s inadequate preflight inspection of the airplane’s fuel quantity, which resulted in a total loss of engine power due to fuel starvation.

NTSB narrative

Before takeoff, the pilot estimated that 19 gallons of fuel remained in the airplane based on approximate flight time and fuel burn since the last refueling. His displays read 30 gallons remaining. He departed on a 20 nautical mile flight and shortly after takeoff the engine began to run rough. The engine stopped running rough and the pilot scanned the engine instruments which displayed normal readings. The pilot continued to his destination but had second thoughts and decided to return to his home field. While in cruise flight at 4,500 ft mean sea level, the engine quit. The pilot performed a forced landing to a corn field. The airplane sustained substantial damage to the wings during the forced landing. A postaccident examination determined there was no fuel in the right tank and 6.5 gallons in the left tank. When electrical power was applied to the airplane, the right tank display indicated ½ full. The fuel quantity of the airplane was last calibrated in 2006 when it was modified with a dual bladder system.
