Unable to stop, the airplane continued off the end of the runway, through a fence, off an embankment, and onto a road. The pilot stated that upon exiting the airplane, he noticed about a 10-15 knot tailwind. A postaccident examination of the airplane revealed substantial damage to the gear box. The pilot reported that there were no preaccident mechanical malfunctions or anomalies that would have precluded normal operation. ## Aircraft - Registration: [N1393F](https://openairdocs.org/aircraft/N1393F), registered now, S/N 18502840, built 1975 (OpenAirDocs) - Reported make and model: CESSNA A185F (NO SERIES) - Registry model: [Cessna A185F](https://openairdocs.org/model/cessna-a185f) (registry code 2072821) (OpenAirDocs) - Registry engine: [Continental IO-520 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 18502840 - Year built: 1975 - Airframe hours: 1620 - Engines: Continental IO520D115B 300 hp reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, June 25, 2021, 311 hours before - Departed: KRKP, Rockport, TX - Destination: PVT, Blanco, TX - Airport: PVT, Private, runway 17, 2,000 × 100 ft, grass/turf - Equipment: Stall warning system, ADS-B, Auto-pilot, Electronic primary flight display ## Flight crew As NTSB recorded them.
