During an examination of the brakes it was found that the left brake piston would not release the disc when manually pushed in. No further mechanical anomalies were noted with the brake system. ## Factual narrative On March 3, 2002, at 1130 mountain standard time, an experimental Fairchild 24W-46, N77618, nosed over during the turnoff from landing at the Marana Northwest Regional Airport (AVQ), Marana, Arizona. The airplane, owned and operated by the private pilot under the provisions of 14 CFR Part 91, sustained substantial damage. The pilot, the sole occupant, was not injured. Visual meteorological conditions prevailed. The cross-country flight departed the Casa Grande Municipal Airport, Casa Grande, Arizona, about 1100, and was destined for AVQ. No flight plan had been filed. In the pilot's written statement, he indicated that he made a normal wheel landing. On rollout he applied rudder and then brake to maintain directional control. He stated that the left brake locked up and the airplane went over on it's back. During retrieval of the airplane, the brake pads were loosened. Both the owner and the person assisting with the retrieval noted that there was no clearance of the brake pads. When they attempted to push in the piston to release the disk they found it could not be moved. They also noticed that the brake pads were discolored. No further discrepancies were noted with the brake system. ## Aircraft - Registration: [N77618](https://openairdocs.org/aircraft/N77618), registered now, S/N W46-318, built 1946 (OpenAirDocs) - Reported make and model: Fairchild 24W-46 - Registry model: [Fairchild 24W-46](https://openairdocs.org/model/fairchild-24w-46) (registry code 3370626) (OpenAirDocs) - Registry engine: [Warner SS165 series](https://openairdocs.org/engine/warner-ss165-series) (registry code 64504, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: W46318 - Airframe hours: 1284 - Engines: Warner SS-165 165 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Paul Conn - Last inspection: Annual, November 1, 2001, 9 hours before - Departed: CGZ, CASA GRANDE, AZ - Destination: AVQ, TUCSON, AZ - Airport: AVQ, Marana Northwest Regional Airp, runway 12, 6,901 × 100 ft, asphalt ## Flight crew As NTSB recorded them.
