Narrative Report
On October 17, 1998 at 02:30 AM, Billings - Missoula experienced a crash involving Beechcraft 99 Airliner, operated by Alpine Air, with the event recorded near Missoula Montana.
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. While flying a night visual approach, the co-pilot flared too high above the runway. As the aircraft floated down the runway, the speed decreased, and the pilot-in-command took control. Because he felt the aircraft was approaching a stall, he initiated a go-around. During the attempted go-around, the pilot-in-command found it necessary to keep both hands on the control wheel due to the fact that the aircraft had been trimmed to the full nose-up position during the landing flare. Even with both hands on the control wheel, the aircraft became very difficult to control. Although the co-pilot moved the throttles to maximum power and began retraction of the flaps, the pilot-in-command's remedial action had occurred too late to successfully execute the go-around. It was later discovered that during the operator's initial training, both crew members had been taught to apply full nose-up trim after crossing the runway threshold and reducing the power to idle. This action, which the operator eliminated from the landing sequence procedure after this accident, was inconsistent with the instructions in the Beech 99 Pilots Operating Manual.
Aircraft reference details include registration N299GL, MSN U-102, year of manufacture 1969.
Geospatial coordinates for this crash are approximately 46.8701°, -113.9953°.
