The right wing and fuselage sustained substantial damage. After the accident, a runway inspection revealed a continuous black tire mark from near the runway centerline, consistent with the position of the left main gear when landing. The tire mark terminated at the runway edge, where a tire impression began and continued to the wreckage location. A postaccident examination of the left wheel brake revealed corroded caliper pins, which prevented the brake caliper from free floating as designed. This corrosion likely prevented the tire from rotating and resulted in the uncorrectable veer off the runway. ## Factual narrative On June 21, 2023, about 1447 central daylight time, a Cessna 175, N9354B, was substantially damaged when it was involved in an accident near Mesquite, Texas. The pilot and passenger were uninjured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. According to the pilot, after touchdown on the runway the airplane veered to the left, exited the runway, and impacted a precision approach path indicator light. The right wing and fuselage sustained substantial damage. After the accident, a runway inspection revealed a continuous black tire mark from near the runway centerline, consistent with the position of the left main gear when landing. The tire mark terminated at the runway edge, where a tire impression began and continued to the wreckage location. During a postaccident examination, the left wheel brake caliper was wedged and unable to free float with corrosion present on the caliper pins. The pilot stated that following the last annual inspection, he took the airplane to Alaska to conduct back-country flying. This was the only time the airplane was stored outside. Normally, the airplane remained in a hangar in Texas and out of the elements. ## Aircraft - Registration: [N9354B](https://openairdocs.org/aircraft/N9354B), registered now, S/N 55154, built 1958 (OpenAirDocs) - Reported make and model: CESSNA 175 - Registry model: [Cessna 175](https://openairdocs.org/model/cessna-175) (registry code 2072502) (OpenAirDocs) - Registry engine: [Continental GO-300 series](https://openairdocs.org/engine/continental-go-300-series) (registry code 17024, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 55154 - Year built: 1958 - Engines: Lycoming O-360-A1D reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, August 5, 2022 - Airport: HQZ, Mesquite Metro, runway 18, 6,000 × 100 ft, concrete ## Flight crew As NTSB recorded them.
