When the airplane was about halfway down the runway during the takeoff roll, the pilot saw that the airspeed indicator was not functioning and decided to abort the takeoff. The pilot moved the throttle to idle and applied the brakes, but the airplane did not slow as expected, and the airplane continued to roll to the end of the runway. Despite maximum braking efforts, the airplane overran the end of the runway and impacted a drainage culvert. The pilot and passengers exited the airplane before it was destroyed by a postcrash fire that originated from the engine area. Though the pilot reported malfunctions of the airspeed indicator and brakes, the postcrash fire destroyed most of the airplane, and precluded an examination of these systems. As a result, the reasons for the reported failure of the airspeed indicator and brakes could not be determined based on the available evidence. ## Aircraft - Registration: [N42725](https://openairdocs.org/aircraft/N42725), registered now, S/N 18259165, built 1968 (OpenAirDocs) - Reported make and model: CESSNA 182L - Registry model: [Cessna 182L](https://openairdocs.org/model/cessna-182l) (registry code 2072726) (OpenAirDocs) - Registry engine: [Continental O-470 series](https://openairdocs.org/engine/continental-o-470-series) (registry code 17026, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 18259165 - Year built: 1968 - Airframe hours: 3555 - Engines: Continental O-470-R 230 horsepower reciprocating - Damage: Destroyed - Fire: On-Ground - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, February 17, 2025, 41.9 hours before - Airport: RYN, Ryan Field Airport, runway 33, 4,010 × 75 ft, asphalt - Equipment: Stall warning system, ADS-B ## Flight crew As NTSB recorded them.
