Beechcraft 99 Airliner

The twin engine airplane departed Manchester-Boston Regional Airport Runway 06 at 0709LT on a cargo service (flight WIG1046) to Presque Isle. After takeoff, the airplane entered a left turn and climbed to 2,700 feet when the pilot reported problems to ATC. He followed several circuits over Manchester, Auburn and Merrimack with erratic courses and varying altitude and speed. Finally, the airplane entered a right turn and crashed in a forest located near Londonderry, about 8 km south of Manchester Airport. The accident occurred 17 minutes after departure. The pilot was seriously injured and the airplane was destroyed.

The crew departed Auburn-Lewiston Municipal Airport on a local training mission under callsign WIG634. After making a circuit over Sebago Lake located southwest of the airport, the crew continued to the northeast when control was lost. The airplane entered a descent with a rate of 7,300 feet per minute until it crashed in a wooded area located near Mt Oak Hill, about 25 km northeast of Auburn-Lewiston Municipal Airport. The airplane was destroyed and both occupants were killed.

Shortly after departure from Lansing-Capital Region Airport, while climbing, the pilot reported rudder control problems and was cleared for an immediate landing. Shortly later, the airplane impacted the ground and came to rest in a grassy area located near taxiway B. The pilot evacuated safely and the airplane was damaged beyond repair.

The crew departed Bogotá on a training flight to Mariquita with an intermediate stop at Ibagué-Perales Airport. While on approach by night, the twin engine aircraft went out of control and crashed in a field located few km from the airport, bursting into flames. The aircraft was totally destroyed by a post crash fire and all four crew members were killed.

According to the operator's director of safety, during landing in gusty crosswind conditions, the multi-engine, turbine-powered airplane bounced. The airplane then touched down a second time left of the runway centerline. "Recognizing their position was too far left," the flight crew attempted a go-around. However, both engines were almost at idle and "took time to spool back up." Without the appropriate airspeed, the airplane continued to veer to the left. A gust under the right wing "drove" the left wing into the ground. The airplane continued across a grass field, the nose landing gear collapsed, and the airplane slid to a stop. The airplane sustained substantial damage to the fuselage and left wing. The director of safety reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation. The automated weather observation system located at the accident airport reported that, about the time of the accident, the wind was from 110° at 21 knots, gusting to 35 knots. The pilot landed on runway 04. The Beechcraft airplane flight manual states the max demonstrated crosswind is 25 knots. Based on the stated wind conditions, the calculated crosswind component was 19 to 33 knots.
