The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Narrative: pilot w.l. archer was giving flight instruction to tony larosa on 01-15-94. Enroute to the practice area, a slight vibration was noted. The aircraft was turned back toward the airport and climbed from 2000' to 2500', the vibration increased. The engine was developing approximately 2100 RPM with full throttle. ATC was notified of the problem and the aircraft was cleared to land. At approximately 2.5 miles from the airport, the engine quit. The aircraft glided to a landing on the grass, short of runway 32 and stopped on taxi way echo. There were no injuries nor damage to the aircraft. Investigation disclosed no. 3 cylinder was separated from the engine case. It appears the problem was due to failure of the connecting rod cap bolt (p/n sl 78027) in the no. 3 cylinder. This office plans no further action concerning this matter. An m&d dated 01-15-94 was submitted to AFS-640. Asw mido 42 was notified.
