What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) 45 Minutes into a night flight returning to big lake TX from lubbock TX, the engine began to run ruff. The pilot adjusted the misture and throttle, switched fuel tanks and tried the boost pump but nothing helped. He set his transponder on 7700 and transmitted on 121.5 that he was making an emergency landing 20 miles south of lamesa TX on highway 87. He checked the magnetos but the engine would not produce enough power to continue flight, so he landed on the south bound lane of highway 87 and shut down the engine. There was no additional damage done to the airplane, inspection of the engine showed that the #4 cylinder (left rear) had internal damage privacy data omitted
