Analysis

The private plt was practicing landings at centennial airport, denver, Colorado. Rnwy 17L, an asphalt rnwy 8,500 feet long and 101 feet wide, was in use. The plt reported that when he attempted to add power on final approach, the throttle cable would not move. Several attempts were made to free the throttle to no avail. The engine remained at 1700 RPM and the aircraft undershot the approach. The aircraft impacted one quarter mile short of the runway in a field. A post accident inspection provided evidence that the plastic coating on the throttle cable had disintegrated. Pieces of the coating were found in the outer housing.
