The defining event best describes what happened. - [Landing-landing roll: Landing gear collapse](https://openairdocs.org/ntsb-events/094) (defining event); cases with it: [Cessna U206G, 2 cases](https://openairdocs.org/ntsb-events/094/sequence.md?model=2073356), [All aircraft, 1,787 cases](https://openairdocs.org/ntsb-events/094/sequence.md) ## Analysis The pilot of the wheel-equipped tricycle gear airplane reported that, he was landing on a hard packed snow-covered airstrip. After touchdown and during the landing rollout the right main tire and nose wheel broke through the hard crusted snow. The nose gear assembly collapsed, and the right wing struck the ground. The airplane sustained substantial damage to the right wing. The pilot reported no preaccident mechanical failures or malfunctions that would have precluded normal operations. In the recommendation section of the NTSB Accident/Incident Reporting Form 6120.1, the operator stated that the accident may have been prevented if the mission parameters had been clearly stated to the pilot, and that hard packed snow will no longer be considered a suitable landing area for wheel-equipped airplanes. ## Aircraft - Registration: [N1748R](https://openairdocs.org/aircraft/N1748R), registered now, S/N U20605438, built 1980 (OpenAirDocs) - Reported make and model: CESSNA U206G - Registry model: [Cessna U206G](https://openairdocs.org/model/cessna-u206g) (registry code 2073356) (OpenAirDocs) - Registry engine: [Continental IO-520-D](https://openairdocs.org/engine/continental-io-520-d) (registry code 17236, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: U20605438 - Year built: 1980 - Airframe hours: 3498.8 - Engines: CONT MOTOR IO-520-D 300 horsepower reciprocating - Damage: Substantial damage - Flight: Part 135 - Operator: Alaska Skyways Inc., doing business as Regal Air - Registered owner: Northstar Holdings LLC - Airworthiness certificate: Standard, Normal - Last inspection: Annual, October 27, 2020 - Departed: PAWS, Wasilla, AK - Destination: Same as departure - Flight plan: Company VFR - Airport: 8KA, Tatitna, runway 06/24, 1,200 × 12 ft, snow - Equipment: ADS-B, Handheld GPS, Satellite tracking device ## Flight crew As NTSB recorded them.
