Incident at LETHBRIDGE AB (CYQL)

Summary

2003-04-22: The pilot of C-ICLM, a Birdman Chinook ultralight aircraft, had just departed Runway 23 at Lethbridge for a local flight. The a/c had climbed to about 200 feet AGL when the aircraft seemed to stop climbing in spite of full power being applied. The pilot turned the a/c and conducted a forced landing about 700 meters north of the runway. The pilot was not injured and the aircraft lost a wheel and broke a window. TSB spoke to the pilot, who reported that he believes that the belt tension on the propeller was insufficient.
2003-04-23: UPDATE TSB reported that the Birdman Chinook ultralight, registration C-ICLM, departed Runway 23 at Lethbridge and climbed to about 200 feet above ground, then began to lose airspeed and altitude. The pilot forced-landed on the airport infield, about 700 meters north of the departure runway. The right main gear detached and one side window broke during the landing roll; however, the pilot was uninjured. The ultralight was fitted with a 28 horsepower Rotax 277 engine and a fixed pitch wooden propeller. Examination indicated that the belts driving the propeller had lost tension, and that they may have slipped under climb power.
