Upon landing, the airplane bounced slightly and, after the tailwheel touched down, the airplane veered sharply to the right. The pilot attempted to maintain directional control with left rudder and brake; however, the airplane departed the runway and traveled into the grassy area between the runway and taxiway. As the airplane slowed, it turned sharply to the right, which allowed the right wing to contact the ground. While the pilot thought that the left brake may have failed after touchdown, due to the damage to the landing gear assembly he was not able to perform a brake inspection. A Federal Aviation Administration inspector examined the airplane with no mechanical anomalies identified. ## Factual narrative The pilot was returning from a 1-hour local area flight. Upon landing, the airplane bounced slightly, and after the tail wheel touched down, the airplane veered sharply to the right. The pilot attempted to maintain directional control with left rudder and brake; however, the airplane departed the runway and into the grassy area between the runway and taxiway. As the airplane slowed, it turned sharply to the right, which allowed the right wing to contact the ground. The pilot thought that the left brake may have failed after touchdown, but due to the damage to the landing gear assembly it was not possible to perform a brake inspection. A Federal Aviation Administration (FAA) inspector examined the airplane with no mechanical anomalies identified. ## Aircraft - Registration: [N5491W](https://openairdocs.org/aircraft/N5491W), registered now, S/N 081, built 2005 (OpenAirDocs) - Reported make and model: TEW WILLIAM P TEAM ROCKET F1 - Registry model: [Tew William P TEAM ROCKET F1](https://openairdocs.org/model/tew-william-p-team-rocket-f1) (registry code 05613VQ) (OpenAirDocs) - Registry engine: [Amateur-built UNKNOWN ENG](https://openairdocs.org/engine/amateur-built-unknown-eng) (registry code 99999) (OpenAirDocs) - Category: Airplane, amateur-built - Serial number: 081 - Airframe hours: 390 - Engines: Lycoming IO-540-C4B5 290 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Special, Experimental (Special) - Last inspection: Continuous airworthiness, April 17, 2011, 2 hours before - Departed: 36U, Heber, UT - Destination: 36U, Heber, UT - Airport: 36U, Russ McDonald Field, runway 03, 6,898 × 75 ft, asphalt ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
