He then departed back to his home airport, where he conducted another touch-and-go landing. The student pilot stated that the approach for the second landing was fine but during the landing flare, he believed that he was approaching the end of the runway too fast. The student pilot decided to execute a go-around by increasing engine power and retracting the wing flaps. He stated that the airplane settled onto the runway and he attempted to apply brakes. The airplane veered off the left side of the runway and impacted a pole and a building, resulting in substantial damage to the engine firewall. The student pilot stated that there were no mechanical malfunctions or anomalies with the airplane. ## Factual narrative The student pilot stated that he and a passenger departed on a local flight to a tower-controlled airport, where he conducted five touch-and-go landings and one full-stop landing. He then departed back to his home airport, where he conducted another touch-and-go landing. The student pilot stated that the approach for the second landing was "fine," but during the landing flare, he felt that he was "approaching the end of the runway too fast." The student pilot decided to execute a go-around, added power, and "pulled out all of [the] flaps." He stated that the airplane "lost all its lift," and settled onto the runway. After the airplane touched down, the student pilot attempted to apply brakes. The airplane "jerked" off the left side of the runway and impacted a pole and a building, resulting in substantial damage to the engine firewall. The student pilot stated that there were no mechanical malfunctions or anomalies with the airplane. ## Aircraft - Registration: [N51745](https://openairdocs.org/deregistered/N51745-2012-12-11), registration cancelled 2012-12-11, S/N 17274341, built 1980 (OpenAirDocs) - Reported make and model: CESSNA 172 (P) - Registry model: [Cessna 172P](https://openairdocs.org/model/cessna-172p) (registry code 2072436) (OpenAirDocs) - Registry engine: [Lycoming 0-320 series](https://openairdocs.org/engine/lycoming-0-320-series) (registry code 41508, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 17274341 - Engines: LYCOMING O320 180 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Hixson Aviation - Registered owner: Air-Planes LLC - Airworthiness certificate: Standard, Normal; Standard, Utility - Departed: 1A0, Chattanooga, TN - Destination: 1A0, Chattanooga, TN - Flight plan: Unknown - Airport: 1A0, Dallas Bay Sky Park, runway 05, 3,025 × 50 ft, asphalt ## Flight crew As NTSB recorded them.
