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

During a local flight, the pilots observed oil accumulating on the windscreen and felt vibration of the airplane. They returned to the departure airport, but came in too high and fast on the approach to land, so they attempted a go-around. Although the pilot applied full throttle for the go-around, it '...resulted in little [additional] power and very high vibration.' As the pilot performed a left turn, the engine lost power completely. The airplane impacted trees and shrubs during the forced landing. Examination of the engine found that the 'P' lead insulation on both magnetos had deteriorated and intermittently grounding the magnetos. The FAA Inspector stated that the 'P' leads were probably 'original equipment' on the airplane, which was manufactured in 1959. He also stated that the 'P' lead condition could have resulted in the magnetos 'grounding out,' resulting in loss of engine power. The most recent annual inspection of the airplane was completed almost 14 months before the accident. The pilot did not have a current medical certificate or biennial flight review.

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

inadequate maintenance and inspection, and the pilot overshooting the approach to land.
