Chief N68N accident near Mt. Zion, Illinois

Probable cause

A total loss of engine power for reasons that could not be determined based on the available information.

NTSB analysis

The private pilot and passenger were conducting a cross-country flight in the experimental, amateur-built airplane. While in cruise flight about 1 hour after takeoff, the engine experienced a total loss of power and the pilot performed a forced landing in a bean field. The airplane nosed over after touchdown, crushing the top of the rudder. The pilot told Federal Aviation Administration (FAA) inspectors that, before moving the airplane to its hangar following the accident, he drained the fuel tanks because he did not want fuel leaking on the hangar floor. He reported that he drained 13 gallons; this could not be confirmed by the FAA inspectors. A cursory examination of the engine established drive train continuity when the propeller was turned by hand; however, based on the available information, the reason for the loss of engine power could not be determined.
