There was no damage to the airplane, which was being operated by Hageland Aviation Services Inc., Anchorage, Alaska, as a scheduled visual flight rules (VFR) passenger/cargo flight under Title 14, CFR Part 135 when the accident occurred. The first officer and the sole passenger were not injured. Visual meteorological conditions prevailed, and a company VFR flight plan was filed. The flight departed Kotzebue about 0830, and was bound for Point Hope, Alaska. During a telephone conversation with the National Transportation Safety Board (NTSB) investigator-in-charge (IIC) on July 9, the director of operations for the operator said that about 30 minutes after the airplane departed Kotzebue, the captain went to check the cargo, leaving the first officer to fly the airplane. He said while the pilot was out of his seat, the airplane encountered unforecast turbulence, and the captain fell, breaking his ankle. He said the first officer returned the flight to Kotzebue to seek medical attention for the captain. ## Aircraft - Registration: [N410GV](https://openairdocs.org/aircraft/N410GV), registered now, S/N 208B0632, built 1997 (OpenAirDocs) - Reported make and model: CESSNA 208B - Registry model: [Cessna 208B](https://openairdocs.org/model/cessna-208b) (registry code 2073701) (OpenAirDocs) - Registry engine: [Pratt & Whitney PT6A series](https://openairdocs.org/engine/pratt-whitney-pt6a-series) (registry code 52032, turbo-prop) (OpenAirDocs) - Category: Airplane - Serial number: 208B0632 - Airframe hours: 8200 - Engines: Pratt & Whitney Canada PT6A-114A 675 horsepower turbo prop - Damage: No damage - Flight: Part 135 - Operator: Hageland Aviation Services Inc, doing business as Hageland Aviation Services, Inc. - Registered owner: Gussic Ventures, LLC - Airworthiness certificate: Standard, Normal - Last inspection: AAIP, July 16, 2003 - Departed: PAQT, Kotzebue, AK - Destination: PAPO, Point Hope, AK - Flight plan: Company VFR ## Flight crew As NTSB recorded them.
