Accident Sequence
On December 2, 2018, at approximately 1940 coordinated universal time, a Cessna 172P, registered as N98884, was substantially damaged during an accident near Santa Rita, Guam. The commercial pilot and a passenger received minor injuries. The flight was conducted under Title 14 Code of Federal Regulations Part 91 as a personal flight.
The pilot reported that a standard preflight inspection was performed, and the engine run-up and takeoff proceeded normally. After takeoff, the pilot flew around the island and circled a nearby harbor at an altitude of about 1,500 ft mean sea level before initiating a climb. When the airplane reached approximately 2,500 ft, the pilot heard a clear reduction in engine power. The tachometer indicated a decrease from about 2,500 rpm to 1,800 rpm, followed by an abrupt loss of power. No abnormal noises or visible leaks were noted before the power loss.
Faced with the loss of engine power, the pilot executed a forced landing onto an abandoned runway. The airplane landed long, overran the end of the runway, and struck vegetation before coming to rest. The wings sustained substantial damage during the event.
Postaccident Examination
A postaccident examination of the airframe and engine revealed no anomalies. The spark plugs were removed and showed wear consistent with normal operation. The propeller was rotated by hand, and drivetrain continuity to the accessory section was confirmed. Thumb compression was established on all cylinders, and spark was observed on the spark plug leads. Fuel lines were examined and appeared normal, with no blockages detected.
