Read the full NTSB narrative

Just after takeoff, the airplane's engine experienced a partial power loss, so the pilot elected to make an emergency landing on rough terrain when it appeared that he would not clear trees in his path. During the pilot's attempts to stop, the airplane nosed over onto its back. A post-accident inspection determined that the engine's right magneto had malfunctioned due to the resistance of the secondary coil windings being out of serviceable limits.
