Lpine air taxi was on visual approach and the pilot attempted to go around for unknown reasons when the acft struck the rwy. Landing gear collapsed,acft skidded off the rwy and came to rest 5O feet from the rwy.(-23)on October 17, 1998 at 02:54 MDT, Beech craft model B-99, serial number U-102, inpacted the ground tearing off the main landing gear, just south of runway 29 at Missoula airport. The captain stated that the flight to Missoula was the first officers leg, and during landing the first officer flared too high. The captain and first officer were unable to regain control of the aircraft. The captain sustained minor injuries in the accident. (.19)on October 17, 1998, approximately 0254 mountain daylight time, a Beech 99, N299GL, impacted the terrain during an attempted go-around from a night visual approach at Missoula International Airport, Missoula, Montana. The aircraft, which is registered to clb corporation of provo, Utah, and operated as alpine air 5010 sustained substantial damaged. The captain, who holds an airline transport pilot certificate, reveived minor injuries and the copilot, who holds a commercial certificate was uninjuried. The 14 CFR part 135 cargo flight which departed billings, Montana approximately 1 hour 32 minutes prior to the accident, had been IFR en route. According to the crew, during the copilot's attempt to land on runway 29, the captain took control of the aircraft and initiated a go-around when he became uncomfortable with the landing approach. However; he was unable to arrest the sink rate before impacting the terrain. (.4)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 e xcute 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.
