The engine's inability to provide full power, and the pilot's failure to use performance data. Factors in the accident were conditions conductive for carburetor icing at reduced power, and the unsuitable terrain during the forced landing.

Read the full NTSB narrative

The pilot reported that he made a normal, flaps-up takeoff with full throttle. The point on the runway where he became airborne was about 2,800 feet from where the initial takeoff roll began. The pilot stated he climbed out at 90 to 100 mph, and 2,400 to 2,500 rpm. He said that the rpm dropped to 2,100, and then to 1,900. The pilot then performed a forced landing to a building roof top. According to the owner's manual, the calculated takeoff distance was less than 700 feet. Certification data revealed that at 90 to 100 mph, the geared engine should have produced about 2,900 to 3,000 rpm. A carburetor icing probability chart showed that for the ambient conditions, and with less than full power, moderate icing could result. A manufacturer's service instruction stated that 'the possibility of throttle icing at wide throttle openings is very remote, so remote in fact, that it can be disregarded.'
