Flight Overview
America West Airlines Flight 166, a Boeing 737, departed Phoenix, Arizona, en route to Durango, Colorado. The flight conducted an instrument landing system (ILS) approach to Durango's Runway 02 in instrument meteorological conditions (IMC).
Approach and Landing
During the approach, the captain used a 10- to 15-degree crab angle to maintain the localizer course. The aircraft touched down approximately 1,000 to 1,300 feet from the runway threshold. Upon touchdown, the speedbrakes deployed automatically.
Runway Excursion
After landing, the aircraft began to drift to the left of the runway centerline. The captain applied right rudder and right nosewheel steering, but these actions produced no effect. Reverse thrust was not employed. Approximately 3,000 feet from the runway threshold, the left main landing gear sank in soft snow along the runway edge. The aircraft subsequently veered to the left and came to a halt.
Conclusion
The aircraft came to rest left of the runway after the left main landing gear encountered soft snow. No further details were provided in the source.
