Probable cause

The loss of engine power during cruise due to the separation of the spark plug because of the loose threads. Contributing to the accident was trees.

NTSB narrative

The pilot reported that during cruise flight, about 700 feet above the ground, the engine lost power. He stated that he attempted to troubleshoot the power loss to no avail. He then selected a landing site, but did not have sufficient altitude and landed the airplane in trees. The airplane came to rest in the tree tops and had sustained substantial damage due to the impact with the trees. Examination of the engine subsequent to the accident revealed that the spark plug had fallen out of its threaded hole. Examination of the threads revealed that they were loose and had been re-cut at some time in the past.
