The defining event best describes what happened. - [Landing: Hard landing](https://openairdocs.org/ntsb-events/092) (defining event); cases with it: [Cessna U206G, 5 cases](https://openairdocs.org/ntsb-events/092/sequence.md?model=2073356), [All aircraft, 2,102 cases](https://openairdocs.org/ntsb-events/092/sequence.md) ## Analysis During an air taxi flight, the pilot executed a glassy-water landing on a remote lake with an excessive descent rate which resulted in a hard landing and go-around. The pilot later successfully landed the airplane without further incident. The hard landing resulted in the front seat passenger sustaining a broken rib. All three persons aboard were seated and wearing lap belts without shoulder harasses. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. The front-seat passenger stated the sun’s position in the sky – combined with the glassy water surface conditions - produced significant sun glare, especially on the pilot’s side of the airplane. ## Aircraft - Registration: [N756SG](https://openairdocs.org/aircraft/N756SG), registered now, S/N U20604315, built 1978 (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 series](https://openairdocs.org/engine/continental-io-520-series) (registry code 17032, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: U20604315 - Year built: 1978 - Airframe hours: 9058 - Engines: Continental IO-550-F12B 300 horsepower reciprocating - Damage: Minor damage - Flight: Part 135 - Operator: Waters Aero Marine Inc, doing business as Penobscot Island Air - Registered owner: Waters Aero Marine Inc - Airworthiness certificate: Standard, Normal - Last inspection: AAIP, August 22, 2022 - Departed: 70B, Millinocket, ME - Destination: Same as departure - Equipment: Satellite tracking device, ADS-B ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
