He reported that the ground loop was prevented but the airplane nosed over as a result of the brake input. A postflight inspection revealed substantial damage to the fuselage, the right wing support strut, and the empennage. The pilot reported there were no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. ## Factual narrative The pilot reported that after the touchdown, right rudder and brake was applied to counter a ground loop. He reported that the ground loop was prevented but the airplane nosed over as a result of the brake input. A postflight inspection revealed substantial damage to the fuselage, the right wing support strut, and the empennage. The pilot reported there were no pre-impact mechanical failures or malfunctions with the airframe or engine that would have precluded normal operation. The pilot reported as a safety recommendation, for "more judicious use of brakes in the future." ## Aircraft - Registration: [N2099V](https://openairdocs.org/deregistered/N2099V-2018-05-30), registration cancelled 2018-05-30, S/N 14324, built 1948 (OpenAirDocs) - Reported make and model: CESSNA 120 (NO SERIES) - Registry model: [Cessna 120](https://openairdocs.org/model/cessna-120) (registry code 2071402) (OpenAirDocs) - Registry engine: [Continental C85 series](https://openairdocs.org/engine/continental-c85-series) (registry code 17008, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 14324 - Year built: 1946 - Engines: Continental C-85-12 85 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, May 1, 2015 - Departed: TKI, McKinney, TX - Destination: TKI, McKinney, TX - Airport: TKI, Collin County Rgnl At Mc Kinne, runway 18, 7,002 × 150 ft, concrete ## Flight crew As NTSB recorded them.
