Subsequently, the propeller and fuselage impacted the runway and the airplane skidded to a stop. The airplane’s firewall and fuselage sustained substantial damage. The pilot reported, and a postaccident examination corroborated that, there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. ## Aircraft - Registration: [N392DC](https://openairdocs.org/aircraft/N392DC), registered now, S/N C0292, built 2004 (OpenAirDocs) - Reported make and model: DIAMOND AIRCRAFT IND INC DA20-C1 - Registry model: [Diamond Aircraft Ind DA20-C1](https://openairdocs.org/model/diamond-aircraft-ind-da20-c1) (registry code 2990001) (OpenAirDocs) - Registry engine: [Continental IO-240 series](https://openairdocs.org/engine/continental-io-240-series) (registry code 17063, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: C0292 - Year built: 2004 - Airframe hours: 4177 - Engines: Continental IO-240-B 125 horsepower reciprocating - Damage: Substantial damage - Flight: Instructional, Part 91 - Operator: Superior Aviation Gateway LLC - Registered owner: Fly Dynasty Corporation - Airworthiness certificate: Standard, Utility - Last inspection: Annual, January 1, 2021, 12 hours before - Departed: VDF, Tampa, FL - Destination: Same as departure - Airport: VDF, Tampa Executive Airport, runway 18, 3,219 × 75 ft, asphalt - Equipment: Stall warning system, ADS-B ## Flight crew As NTSB recorded them.
