The pilot reported that, during the landing roll, the left brake locked and the airplane veered to the left, departing the side of the runway into a ravine. A postaccident examination of the airplane revealed no mechanical anomalies with the braking system that would have precluded normal operation, and the locked brake condition could not be duplicated; therefore, the reason for the loss of directional control could not be determined. ## Factual narrative On August 20, 2017, about 1300 central daylight time, a Cessna 182R airplane, N182DW, was substantially damaged when it departed the runway while landing at the Jesse Viertel Memorial Airport (KVER), Booneville, Missouri. The private pilot and passenger were not injured. The personal flight was conducted under the provisions of Title 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed and a Federal Aviation Administration (FAA) flight plan had been filed for the flight. The cross-country flight departed Clinton Regional Airport (KCLK) Clinton, Oklahoma, about 1045 and was en route to KVER. According to the pilot, while landing on runway 18 (4,000 ft by 75 ft, asphalt) the left brake locked and the airplane veered off of the runway and into a ravine. The horizontal stabilizer and fuselage were substantially damaged. According to the FAA inspector who responded to the accident, there were rubber witness marks, from both the left and the right tire, in a left turning arc that continued to the edge of the runway. The left tire did not have any flat spots consistent with the tire being locked. The master cylinder was full of hydraulic fluid and there was no evidence of a fluid leak. The brake caliper, brake pads, and left brake disc were all in good condition. The inspector was unable to duplicate the locked brake condition. An examination of the airframe and flight controls revealed no anomalies that would have resulted in a loss of directional control during a landing roll. ## Aircraft - Registration: [N182DW](https://openairdocs.org/deregistered/N182DW-2019-02-26), registration cancelled 2019-02-26, S/N R18200982, built 1979 (OpenAirDocs) - Reported make and model: CESSNA 182 (R) - Registry model: [Cessna R182](https://openairdocs.org/model/cessna-r182) (registry code 2072734) (OpenAirDocs) - Registry engine: [Lycoming 0-540 series](https://openairdocs.org/engine/lycoming-0-540-series) (registry code 41532, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: R18200982 - Year built: 1979 - Airframe hours: 3021.9 - Engines: Lycoming IO-540-J3C5D 235 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, March 16, 2017 - Departed: KCLK, Clinton, OK - Destination: KVER, Boonville, MO - Flight plan: VFR - Airport: KVER, Jesse Viertel Memorial Airport, runway 18, 4,000 × 75 ft, asphalt - Equipment: Stall warning system ## Flight crew As NTSB recorded them.
