However, during the landing rollout the airplane began to veer towards the hangars. The pilot attempted to correct using opposite rudder and right brake, but the airplane struck a hangar and hangar door resulting in substantial damage to the right wing. The pilot reported he had a potential brake failure, but an examination of the airplane conducted by Federal Aviation Administration inspectors confirmed the airplane’s rudder control, braking, and steering functions. At the time of the accident, the pilot was landing the airplane on runway 18 with a 5-knot variable wind. ## Aircraft - Registration: [N85930](https://openairdocs.org/deregistered/N85930-2021-09-27), registration cancelled 2021-09-27, S/N 11AC-355, built 1946 (OpenAirDocs) - Reported make and model: AERONCA 11AC - Registry model: [Aeronca 11AC](https://openairdocs.org/model/aeronca-11ac) (registry code 0191102) (OpenAirDocs) - Registry engine: [Continental A&C65 series](https://openairdocs.org/engine/continental-a-c65-series) (registry code 17003, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 11AC-355 - Year built: 1946 - Airframe hours: 1545 - Engines: Continental A65-8F 65 hp reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Operator: Leupp Matthew - Registered owner: Leupp Matthew - Airworthiness certificate: Standard, Normal - Last inspection: Annual, May 1, 2021, 18.3 hours before - Departed: KLHQ, Lancaster, OH - Destination: Same as departure - Airport: 38OH, Industry Air Park, runway 18, 2,550 × 60 ft, grass/turf - Equipment: Handheld GPS ## Flight crew As NTSB recorded them.
