Narrative Report
On October 16, 2001 at 09:30 PM, Anchorage - Bethel experienced a crash involving Embraer EMB-120 Brasília, operated by ACE Air Cargo, with the event recorded near Bethel Alaska.
The flight was categorized as cargo and the reported phase was landing (descent or approach) at a airport (less than 10 km from airport) crash site.
2 people were known to be on board, 0 fatalities were recorded, 2 survivors were identified or estimated. This corresponds to an estimated fatality rate of 0.0%.
Crew on board: 2, crew fatalities: 0, passengers on board: 0, passenger fatalities: 0, other fatalities: 0.
The listed crash cause is human factor. The captain and first officer were conducting a localizer DME back course approach to runway 36 in a twin-engine turboprop airplane during a night cargo flight under IFR conditions. The minimum visibility for the approach was one mile, and the minimum descent altitude (MDA) was 460 feet msl (338 feet agl). Prior to leaving their cruise altitude, the first officer listened to the ATIS information which included an altimeter setting of 29.30 inHg. No other altimeter information was received until the crew reported they were inbound on the approach. At that time, tower personnel told the crew that the visibility was one mile in light snow, the wind was from 040 degrees at 22 knots, and the altimeter setting was 29.22 inHg. The crew did not reset the airplane altimeters from 29.30 to 29.22. At the final approach fix (5 miles from the runway), the captain began a descent to the MDA. Thirty-six seconds before impact, the first officer cautioned the captain about the airplane's high airspeed. Due to strong crosswinds, the captain disconnected the autopilot 22 seconds before impact. He said he pushed the altitude hold feature on the flight director at the MDA. Eighteen seconds before impact, the airplane leveled off about 471 feet indicated altitude, but then descended again 9 seconds later. The descent continued until the airplane collided with the ground, 3.5 miles from the runway. The crew said that neither the airport, or the snow-covered terrain, was observed before impact. The crew reported that the landing lights were off. The airplane was not equipped with a ground proximity warning system.
Aircraft reference details include registration N120AX, MSN 120-164, year of manufacture 1989.
