Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The pilot reported that he was performing takeoffs and landings when the accident occurred. He said that on one of the landings, when the airplane was on the downwind leg of the traffic pattern, the engine went to idle. The pilot attempted to land the airplane on the runway, but the airplane struck a fence short of the runway. Examination of the airplane revealed that the outer flexible sheath of the throttle cable came loose from the crimped metal sleeve, which was part of the instrument panel fitting. Movement of the cockpit throttle control would not actuate the throttle arm of the carburetor. Records indicated that the airplane was manufactured in 1946 and the throttle cable appeared to be original. No entry indicating replacement of the cable was found in the airplane's maintenance records.
