Probable cause

The NTSB’s determination of the probable cause, and any contributing factors.

The improper repair of the no. 2 engine cylinder, which resulted in the loss of engine power.

Analysis

According to the pilot, while doing maneuvers, the engine lost power. He attempted a forced landing on a narrow road. As the airplane approached the road, the left wing struck a tree and nosed over after turning 180 degrees. The no. 2 engine-cylinder was examined, and revealed that the rocker arm assembly had been repaired. During the repair the rocker boss was welded and ground down beyond standards. The boss had broken, and the rocker arm had separated.

Factual narrative

On June 27, 1998, about 1305 eastern daylight time, a Cessna 150G, N2622J, registered to a private owner, operating as a Title 14 CFR Part 91 personal flight, impacted with a tree during a forced landing near Perry, Florida. Visual meteorological conditions prevailed, and no flight plan was filed. The airplane was substantially damaged. The private-rated pilot and one passenger reported serious injures. The flight had originated from the Perry Airport at 1245.
