A commuter aircraft that crashed on sea ice off Alaska, killing all 10 folks on board, was half a ton chubby for a visit into icy situations, the Nationwide Transportation Security Board mentioned in a preliminary report launched Wednesday (March 19, 2025).

The load is only a “knowledge level” within the ongoing investigation, cautioned Clint Johnson, who runs the NTSB’s Alaska area. A last report together with possible causes can take a 12 months or extra after a crash.

The Feb 6. Bering Air crash was one among Alaska’s deadliest aircraft crashes this century and the third main U.S. aviation mishap in an eight-day stretch. A industrial jetliner and an Military helicopter collided over the Potomac River on Jan. 29, killing 67 folks. A medical transportation aircraft crashed in Philadelphia on Jan. 31, killing all six on board and one other individual on the bottom.

Small airplanes just like the Cessna Caravan on this crash are the workhorses of Alaska, the place a lot of the state’s 200-plus villages are past the street system and solely accessible by air or boat. Residents depend on the commuter planes like folks residing within the Decrease 48 rely upon vehicles, utilizing them to get to medical appointments and conferences, to buy groceries, to go to kinfolk or to attend away highschool sports activities video games.

The only-engine turboprop aircraft was flying that afternoon from the group of Unalakleet to Nome, a visit of about 150 miles (240 kilometers), when authorities misplaced contact lower than an hour after takeoff, David Olson, director of operations for Bering Air, mentioned on the time. The Cessna Caravan went lacking about 30 miles (50 kilometers) from its vacation spot.

A overview of the aircraft’s contents following the crash indicated its estimated gross weight at departure was about 9,865 kilos (4475 kilograms) — about 1,058 kilos (480 kilograms) over the utmost takeoff gross weight for a flight into areas the place icing is within the forecast, the report says. The pilot working handbook notes the utmost allowable takeoff gross weight for a flight into such situations was the identical as the fundamental airplane, 8,807 kilos (3995 kilograms).

Johnson mentioned it stays to be decided whether or not the chubby situations had been an element within the accident. Icing situations had been forecast alongside the route, and it was snowing, with some freezing rain in Nome, he mentioned. Officers try to find out what data was relayed to the pilot, what data he had when he left and whether or not ice situations existed on the crash location, he mentioned.

An electronic mail searching for remark despatched to Bering Air was not instantly returned.

Climate is usually a think about distant Alaska, and whereas flying is commonplace to most Alaskans, it may be a harmful endeavor, mentioned Whitney Energy Wilson, an aviation accident litigation lawyer and pilot in Anchorage.

“Icing ought to be concern for all pilots, however particularly for pilots of smaller plane and pilots who ceaselessly function in situations conducive to icing,” she mentioned. “The load of an plane, the truth that icing is one thing that we’re coping with, these issues must be taken critically as a result of the results could be so tragic.”

Investigators additionally seemed on the aircraft’s altitude. It was flying in an space the place reasonable icing was doable between 2,000 ft (610 meters) and eight,000 ft (2,438 meters) and the place the climate could possibly be hazardous to mild plane, NTSB chairperson Jennifer Homendy mentioned at a information convention in Nome final month.

Contact was misplaced shortly after air visitors management instructed the pilot the runway in Nome can be closed for about quarter-hour for deicing, the report says.

“The controller added that if the pilot wished to ‘decelerate a little bit bit’ to forestall the flight from arriving earlier than the runway reopened, that may be tremendous, and the pilot acknowledged,” the report states.

The pilot handbook additionally signifies an air pace of 95 knots should be maintained to fly in icing situations if de-icing gear is absolutely purposeful.

About three minutes after the pilot was instructed to descend to 4,000 ft, the autopilot disengaged at 3,100 ft and 99 knots, then dropped inside seconds to 70 knots, the report says. The ultimate satellite tv for pc monitoring knowledge happened one minute later, at 3:20 p.m., at an altitude of 200 ft.

The anti-icing system on the wings and tail of the 5-year-old turbo-propeller airplane was designed to forestall ice from accumulating, the report says.

The operator mentioned the amount of deicing fluid was checked throughout every preflight inspection. The pilot is answerable for guaranteeing there’s a enough amount onboard, however there isn’t any requirement to report when it’s added to the airplane. A employee on the Unalakleet airport instructed the pilot that the fluid was accessible, however the pilot instructed her the tank was full, in response to the report.

The U.S. Coast Guard has mentioned it was unaware of any misery alerts from the aircraft. After an in depth search, the wreckage was discovered the next day on a drifting ice floe. The pilot and all 9 passengers had been killed.
