Probable cause

A partial loss of engine power during takeoff due to failure of the left magneto. Contributing to the accident was unsuitable terrain to conduct a forced landing.

NTSB narrative

The pilot departed the turf runway and, shortly after takeoff, the airplane experienced a partial loss of engine power. Unable to out-climb the rising terrain, the pilot intentionally allowed the airplane to stall into the treetops of a heavily wooded area. Examination of the airplane revealed that the left magneto would not produce spark when rotated and subsequent disassembly of the magneto revealed that the cam follower was broken. The magneto had been operated for about 300 hours since it was installed during October 2001. The prior service history of the magneto could not be determined, except that it was in storage for about 9 years prior to its installation on the accident airplane.
