NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

The pilot said that he was flying to the north around 20 feet above the ground, when the engine quit. 'There was no sputtering or warning. It just quit.' The pilot checked the throttle and pulled on the flaps to slow the airplane. 'There was no place to land, so I went into some trees and hit a ditch which flipped me over.' Examination of the airplane's engine revealed that the bottom spark plugs were lead-fouled, and rusted. Examination of the other airplane systems revealed no anomalies. Further examination of the engine revealed that the fuel strainer filter was clogged with debris identified as dirt and rust. An examination of the airplane's maintenance records showed that several airworthiness directives applicable to the airplane had not been complied with. Additionally, several airplane system items requiring annual inspection under 14 CFR part 43 had not been accomplished.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

Engine failure due to fouled and rusted spark plugs, and a clogged fuel filter. Factors relating to this accident were the inadequate annual inspection performed on the airplane, the trees and the ditch.
