On August 22, 1994, at 2000 eastern daylight time, N61774, a Cessna 172M, operated by T.S. Aero of Endicott, New York, crashed during a go-around attempt at Tri-Cities Airport, Endicott, New York. The student pilot was not injured and the airplane sustained substantial damage. Visual meteorological conditions prevailed and a flight plan was not filed. The personal flight was operated under 14 CFR 91. According to the pilot, he was returning from a local preparation flight for his private pilot check ride. He stated that he entered the traffic pattern for a landing on runway 21. He stated that he reduced the power, lowered full flaps, and that the airplane was a little fast. The pilot stated that the airplane touched down, but with not much runway remaining he elected to takeoff. During the takeoff, the engine did not respond when he applied full power. The pilot made a forced landing and the airplane collided with a fence during the landing. The aircraft was examined by an FAA Aviation Safety Inspector. The examination revealed that the bolt that attaches the throttle cable to the carburetor was missing. Search efforts were unable to locate the missing bolt.
