He reported that he did not confirm the landing gear was down and locked, as he was distracted with scanning for the other traffic. During landing, the bottom of the fuselage sustained substantial damage. A postaccident functional test of the landing gear revealed no mechanical anomalies with the landing gear system. The pilot reported there were no preimpact mechanical malfunctions or failures with the airframe and engines that would have precluded normal operation. ## Aircraft - Registration: [N310VD](https://openairdocs.org/deregistered/N310VD-2022-08-06), registration cancelled 2022-08-06, S/N 310N-0123, built 1968 (OpenAirDocs) - Reported make and model: CESSNA 310N - Registry model: [Cessna 310N](https://openairdocs.org/model/cessna-310n) (registry code 2074234) (OpenAirDocs) - Registry engine: [Continental I0-470 series](https://openairdocs.org/engine/continental-i0-470-series) (registry code 17027, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 310N-0123 - Year built: 1968 - Airframe hours: 3515 - Engines: CONT MOTOR I0-470 SERIES 260 horsepower reciprocating; CONT MOTOR I0-470 SERIES 260 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, April 23, 2020 - Departed: UCP, New Castle, PA - Destination: Same as departure - Airport: TSO, Carroll County-Tolson, runway 07/25, 4,300 × 75 ft, asphalt - Equipment: ADS-B, Auto-pilot ## Flight crew As NTSB recorded them.
