Accident Summary
A 35-hour student pilot was landing a 1961 Colt aircraft when a brake control cable failed, causing a total loss of braking action. The aircraft overran the departure end of the runway and struck a ridge in a wheat field adjacent to the airport.
Flight Details
The pilot was aware that the landing was downwind but was concerned about losing visual contact with the airport due to forming fog if he attempted to circle for runway 3. The reported wind was from 030 degrees at 15 knots. The pilot touched down midfield on the 4,800-foot runway. During the landing roll, as the aircraft approached the departure end, the pilot began applying the wheel brakes using the brake lever.
Mechanical Failure
While applying brake pressure, the cable to the brakes snapped at the point where it makes a sharp turn over a pulley (part number 11200-00). This resulted in a complete loss of braking effectiveness. The failed cable assembly, part number 40123-91, is listed in the manufacturer's illustrated parts catalog as a condition item without a specified replacement or retirement time. The aircraft had accumulated 1,715 total airframe hours.
Aircraft Information
The aircraft involved was a 1961 model 'Colt'. No registration or operator details were provided in the report.
