Bering Air Flight 445 Crash Near Nome: NTSB Preliminary Analysis

Near Nome, Alaska, on February 6, 2025, a Textron Aviation (Cessna) 208B Grand Caravan, N321BA, operating as Bering Air flight 445, crashed in Norton Sound during a scheduled commuter flight. Preliminary NTSB findings indicate that the airplane descended offshore after a sequence involving reduced airspeed, reduced engine power, an autopilot disengagement at about 99 knots, and the final loss of communications while the flight was descending toward Nome. Federal investigators are examining the accident with particular focus on the flight’s low-altitude descent profile over the Bering Sea, icing-related operating conditions, and preliminary weight-and-balance issues identified in the report.

Accident Summary

What Happened

According to the NTSB preliminary report, the pilot departed Unalakleet at 1437 Alaska standard time on an IFR clearance to Nome via the EMMMO intersection and climbed to 8,000 ft mean sea level. The flight later began descending toward Nome after receiving current airport information and after air traffic control advised that runway 10/28 was temporarily closed for deicing.

At 1514, after the controller suggested slowing slightly so the airplane would not arrive before the runway reopened, the recorded data showed a decrease in airspeed accompanied by a reduction in engine power. The airplane leveled at 6,000 ft about 1515:30, later descended toward 4,000 ft, and the autopilot disengaged at 1519:35 when the recorded airspeed was about 99 knots.

About 19 seconds after the autopilot disengagement, the airspeed had decreased to about 70 knots and the altitude was about 3,100 ft msl, which marked the end of the available onboard avionics data. The final ADS-B point was recorded at 1520:09 about 32 miles east of Nome and about 12 miles offshore at 1,325 ft msl, and a third-party satellite tracking source recorded a final point at 1520:17 and 200 ft msl before the controller issued a low altitude alert and received no further response.

Aircraft and Operational Context

The airplane was a 2020 Textron Aviation 208B powered by a Pratt and Whitney PT6A-140 turboprop engine and equipped with a McCauley four-blade controllable-pitch propeller. It was configured with two pilot seats and nine passenger seats and fitted with both a fuselage cargo pod and a TKS ice protection system that supplied fluid to porous leading-edge panels, the propeller, and the windshield.

The preliminary report identifies a significant loading issue. Based on the operator’s manifest, the airplane’s preliminary gross takeoff weight was about 9,776 lbs, which the NTSB said was about 969 lbs above the maximum takeoff weight for flight into known or forecast icing conditions and about 714 lbs above the maximum gross takeoff weight permitted under the Aircraft Payload Extender III supplement.

Postaccident examination of the airplane contents produced an even higher estimated departure weight of about 9,865 lbs, with approximately 798 lbs of baggage and cargo onboard. The report also states that the pilot operating handbook supplement for the TKS system specified a minimum indicated airspeed of 95 knots for operations in icing conditions, a parameter that may become technically important as investigators evaluate the descent profile and aircraft performance.

Accident Investigation

Because this is an NTSB preliminary investigation, the factual record is still developing and no probable cause has been issued. Readers looking for a broader explanation of how factual reports, laboratory work, and later Board findings fit together can review the firm’s overview of the NTSB investigation process.

The current reconstruction relies on archived FAA ADS-B data, preliminary Anchorage ARTCC communications, preliminary onboard avionics data, and later satellite tracking information. That multi-source sequence places the airplane at 6,000 ft, then 4,000 ft, then 1,325 ft msl offshore in Norton Sound, with the last satellite point at 200 ft msl only seconds before communications ended.

On-scene findings add several technical data points that investigators will need to reconcile with the flightpath evidence. The wreckage was located on a large floating icepack in Norton Sound, the airplane came to rest upright, the flap actuator extension was consistent with flaps retracted, and the initial airframe examination found no evidence of an in-flight structural failure, all of which shows why these matters often require the kind of detailed evidentiary review seen in aviation wrongful death claims.

The NTSB also documented ice-related observations and system-condition evidence that may prove significant. Minor ice accumulation was observed aft of the TKS porous membranes, significant ice accumulation was noted on the base of the beacon or strobe light atop the vertical stabilizer, the TKS tank was too damaged to determine fluid quantity at impact, and recovered avionics equipment was sent to Washington for recorder-laboratory examination.

Operational and Regulatory Issues

The preliminary report frames this accident within a demanding Alaska Part 135 operating environment that combined offshore routing, winter weather, and runway servicing activity at the destination. At Nome, the 1505 weather observation included light snow, a broken ceiling at 2,700 ft agl, overcast at 5,500 ft agl, and a temperature of minus 10 degrees Celsius, while AIRMET Sierra and Zulu were in effect for IFR conditions, mountain obscuration, and occasional moderate icing between 2,000 and 8,000 ft msl.

Those facts do not establish a cause, but they do identify several operational questions investigators are likely to assess closely, including dispatch and release decisions, aircraft loading, icing exposure, speed management during descent, and the practical implications of the temporary runway closure for deicing at Nome. The report also notes that no SIGMETs or center weather advisories were in effect for the accident site at the time.

Regulatory review is also likely to include the operator’s aircraft-loading practices, the use of the TKS-equipped airplane, and compliance with applicable operational requirements in icing conditions.
