WHILE OB THE DOWNWIND LEG IN THE CLOSED TRAFFIC PATTERN, THE ENGINE LOST POWER, AND THE PILOT 'TURNED BACK TO THE RUNWAY.' THE AIRCRAFT TOUCHED DOWN APPROXIMATELY HALF WAY DOWN, OVERRAN THE RUNWAY, TRAVERSED A DITCH AND STRUCK SEVERAL TREES. NO ANOMALIES WERE FOUND THAT COULD HAVE ACCOUNTED FOR THE LOSS OF ENGINE POWER. ## Factual narrative On July 13, 1995, at 1524 central daylight time, a Cessna 172L, N3967Q, was substantially damaged during landing near Porter, Texas. The private pilot was not injured. Visual meteorological conditions prevailed for the personal flight. In an interview with a Federal Aviation Administration inspector, the pilot reported that he was practicing touch and go landings. While on the downwind leg, in preparation for the fourth landing, the pilot stated that the engine "misfired" so he "turned back to the runway." The aircraft "landed long," approximately half way down the runway. Following touchdown the aircraft ran off the end of the runway and traversed across a drainage ditch and subsequently struck several trees. Examination of the aircraft revealed structural damage to the left wing and the right wing separated from the aircraft. No anomalies were found that could have accounted for the loss of engine power. ## Aircraft - Registration: [N3967Q](https://openairdocs.org/aircraft/N3967Q), registered now, S/N 17260067, built 1971 (OpenAirDocs) - Reported make and model: CESSNA 172L - Registry model: [Cessna 172L](https://openairdocs.org/model/cessna-172l) (registry code 2072432) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 17260067 - Engines: LYCOMING O-320-E2D 150 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Isidro C.
