Aviation Accident Preliminary Report - National Transportation Safety Board:

Location: Hooper Bay, AK
Accident Number: ANC20LA020
Date & Time: 02/04/2020, 1558 AKS
Registration: N454SF
Aircraft: Cessna 208
Injuries: 7 None
Flight Conducted Under: Part 135: Air Taxi & Commuter - Scheduled 

On February 4, 2020, about 1558 Alaska standard time, a Cessna 208B Caravan airplane, N454SF, sustained substantial damage after overrunning the end of the runway during takeoff, at the Hooper Bay Airport (HPB), Hooper Bay, Alaska. Of the 8 occupants onboard, the commercial pilot and six adult passengers, along with one infant passenger, were not injured. The airplane was registered to Aviation Capital Corporation and was operated by Grant Aviation under the provisions of Title 14 Code of Federal Regulations (CFR) Part 135 as an instrument flight rules scheduled passenger flight.

Day instrument meteorological conditions prevailed at the time of the accident, and an instrument flight plan was filed. The flight originated from HPB, about 1558, and was destined for Bethel, Alaska (BET).

According to the captain, the weather conditions the day of the accident consisted of snow, low visibility, and flat light. The original flight departure time had been delayed about 3 hours due to weather. The scheduled route of flight was from Bethel (BET), to Scammon Bay (SCM), to HPB, to Chevak (VAK), returning to BET with various passengers and cargo pick-ups and drop-offs along the route. Prior to departure from BET he received runway reports from his dispatcher that all destination airport runways were ready. He also obtained weather at all three destinations. He then did a risk analysis and gathered more weather before deeming the flight conditions good to dispatch the flight.

While enroute to HPB he gathered weather for VAK and determined that the VAK portion of the flight would be canceled due to deteriorating weather. Once in HPB he landed without incident on the snow covered runway. He then called Grant dispatch in BET and informed that he would take all the passengers going to BET since he had canceled his flight to VAK; he loaded 7 passengers total and their bags. During the time on the ground, while waiting for passengers, a twin-engine King Air airplane landed and departed the runway with no incident.

The pilot then back taxied for a runway 13 departure at HPB. He stated that flat light conditions prevailed, and it was difficult to see down the runway or have any depth perception. He initiated the takeoff with 20 degrees of flap selected and noticed no issues during the initial takeoff roll. He then noticed the airspeed was not increasing fast enough, witnessed the end of the runway approaching, and decided he could not abort the takeoff in time. Committed to the takeoff the airplane became airborne and the stall warning horn activated as the airplane cleared the departure end of the runway. The pilot attempted to get the airplane into ground effect, but the airplane settled, and the main landing gear encountered the snow covered terrain. Subsequently, the airplane's speed decreased, the nose wheel descended and encountered the snow, and the airplane came to rest upright about 150 ft from the end of the runway. All crew and passengers evacuated the airplane, and nobody was injured.

The pilot added that the snow on the runway during departure was about 3-5 inches of wet heavy snow.

Airport information for HPB effective January 30, 2020 states under airport remarks,

The automated weather observation system at the accident airport reported that, about the time of the accident, the visibility was 1 1/4 statute miles in light snow, overcast clouds at 1,500 ft, with wind from 060° at 10 knots.

No injuries were reported Tuesday afternoon when a Grant Aviation Cessna 208B Grand Caravan crashed during takeoff in Hooper Bay, according to a Federal Aviation Administration notice posted early Wednesday.

The plane “impacted the ground causing a prop strike," the notice said. There were seven passengers and a pilot on board.

Dan Knesek, director of operations at Grant Aviation, said the commercial flight took off in Hooper Bay around 4 p.m. and was headed to Chevak. Knesek said it’s unclear if or how long the plane was airborne.

“The investigation is just starting,” he said. “We’re working with the National Transportation Safety Board and Federal Aviation Administration as we speak.”

Hooper Bay is a village on the Bering Sea coast in Southwest Alaska.
