He stated that the departure plan was to get the airplane on step into the wind, and then turn lengthwise and depart with a crosswind. During the takeoff run, the airplane “used a fair amount of water on step” before a gust of wind lifted the right wing. In an effort to correct for the gust, the pilot lowered the wing and added power, but the airplane was too close to the bank of the lake, which resulted in an impact with terrain and substantial damage to the fuselage, right wing and tail. The pilot reported no preimpact mechanical malfunctions or failures with the airplane that would have precluded normal operation. In the recommendation section of NTSB Form 6120.1, the pilot stated that a step turn departure may have been more appropriate. ## Aircraft - Registration: [N24BR](https://openairdocs.org/aircraft/N24BR), registered now, S/N 644, built 1953 (OpenAirDocs) - Reported make and model: DEHAVILLAND DHC-2 - Registry model: [Dehavilland DHC-2](https://openairdocs.org/model/dehavilland-dhc-2) (registry code 2808001) (OpenAirDocs) - Registry engine: [Pratt & Whitney R-985 series](https://openairdocs.org/engine/pratt-whitney-r-985-series) (registry code 52008, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 644 - Year built: 1953 - Airframe hours: 20112.3 - Engines: Pratt & Whitney R-985-AN14B 450 horsepower reciprocating - Damage: Substantial damage - Flight: Part 135 - Operator: Branch River Air Service Inc., doing business as Branch River Air - Registered owner: River Front Akn LLC - Airworthiness certificate: Standard, Normal - Last inspection: 100 hour, September 9, 2022 - Destination: PAKN, King Salmon, AK - Flight plan: Company VFR - Equipment: Satellite tracking device, Handheld GPS, ADS-B ## Flight crew As NTSB recorded them.
