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. While maneuvering, the pilot reported that the airplane's engine lost power. He attempted a forced landing on a narrow road. As the airplane approached the road, the left wing struck a tree on the side of the road, turned 180 degrees opposite the direction of flight, rolled over on the nose, and fell to the ground. The engine's No. 2 cylinder was examined at Continental Motor's facilities, Mobile, Alabama, under the supervision of the FAA, on August 19, 1998. The examination revealed that the cylinder No. 2 rocker arm assembly had been repaired. During the repair, the rocker boss was welded and ground down beyond standards.
