N92350

On March 1, 1999, at 1515 central standard time, a Piper J3C-65 airplane, N92350, sustained substantial damage during a forced landing following a loss of engine power on takeoff from Hartlee Field Airport near Denton, Texas. The airplane was registered to and operated by a private individual. The flight instructor sustained minor injuries, and the airline transport pilot receiving instruction was not injured. Visual meteorological conditions prevailed, and a flight plan was not filed for the 14 Code of Federal Regulations Part 91 instructional flight.

The flight instructor reported that the "check out" flight departed Lakeview Airport, Lake Dallas, Texas, about 1440 and proceeded to Hartlee Field. Following a full stop landing, with the pilot receiving instruction on the controls, a takeoff was initiated to the north. According to the flight instructor, "at approximately 100 feet the engine power completely disappeared." The flight instructor took control and turned the airplane approximately 45 degrees left to avoid a steel rail fence at the end of the runway. While the airplane was in the turn, the left wing tip struck the ground. The airplane turned 180 degrees and came to rest heading south approximately 50 feet from the wing touchdown point and 150 feet west of the runway centerline. An FAA inspector examined the airplane and reported that the left wing, main landing gear, propeller, engine, and firewall were damaged.

A mechanic examined the airplane and found "the throttle control cable housing free, due to a broken attaching clamp." The mechanic reported that the broken clamp was made of aluminum; however, a steel clamp, Piper P/N 7536, "should have been used." The mechanic further reported that "the clamp appeared to have been fretting for some time, due to the appearance of the edges, but the main break looked fresh." He did not think the impact broke the clamp, "because when [he] held the cable assembly in its proper place, it was relaxed, with no strain, even though the airframe was bent in that area." The mechanic found no other anomalies during his examination of the airplane.
