He stated that the airplane started to veer to the left and that he applied the right wheel brake to correct for the left turn. He was unable to maintain directional control, and the airplane exited the left side of the runway and nosed over, which resulted in damage to the right wing. Examination of the airplane revealed the left wheel and tire spun freely, whereas the right wheel and brake assembly were tight. Examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal flight operations. Runway skid marks were consistent with the right wheel brake locking up 1,100 ft from the runway threshold, followed quickly by the left wheel brake locking up 1,132 ft from the runway threshold. Both wheel brakes were locked up until the airplane exited the runway 1,500 ft from the threshold. ## Factual narrative On June 28, 2018, about 1130 central daylight time, a Cessna T210N airplane, N6386C, lost directional control while landing at Pocahontas Municipal Airport (M70), Pocahontas, Arkansas. The private pilot was not injured, and the airplane was substantially damaged. The airplane was registered to and operated by ALC Aviation Services LLC under the provisions of Title 14 Code of Federal Regulations Part 91 as a personal flight. Day visual meteorological conditions existed at the time of the landing, which departed from Henry County Airport (PHT), Paris, Tennessee about 1000.After landing on runway 36 with a left quartering tailwind, the pilot stated the airplane veered to the left as if a tire had blown. The pilot attempted to correct to centerline by applying the right brake but was unable to maintain directional control. The airplane subsequently exited the left side of the runway and nosed over, damaging the right wing. Examination of the runway revealed two skid marks starting 1,100 ft and 1,132 ft from the threshold of runway 36. The right skid mark started 32 ft before the left skid mark. Both skid marks continued to the left edge of the 4,000 ft long, 75 ft wide asphalt runway and exited 1,500 ft from the runway threshold. Examination of the airplane revealed the left wheel and tire spun freely, whereas the right wheel and brake assembly were tight. Disassembly of the right wheel and brake assembly revealed the brake linings were new and had recently been replaced. A review of maintenance records revealed the right brake lining had been replaced on numerous occasions as compared to left brake lining. Examination of the airframe and engine revealed no evidence of mechanical malfunctions or failures that would have precluded normal flight operations. ## Aircraft - Registration: [N6386C](https://openairdocs.org/aircraft/N6386C), registered now, S/N 21063879 (OpenAirDocs) - Reported make and model: Cessna T210 (N) - Registry model: [Cessna T210N](https://openairdocs.org/model/cessna-t210n) (registry code 2073456) (OpenAirDocs) - Category: Airplane - Serial number: 21063879 - Year built: 1980 - Airframe hours: 4670 - Engines: Continental Motors TSIO-520-R 310 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: ALC Aviation Services LLC - Registered owner: ALC Aviation Services LLC - Airworthiness certificate: Standard, Normal - Departed: PHT, Paris, TN - Destination: M70, Pocahontas, AR - Flight plan: VFR - Airport: M70, Pocahontas Muni, runway 36, 4,000 × 75 ft, asphalt - Equipment: ADS-B, Stall warning system, Onboard weather ## Flight crew As NTSB recorded them.
