On May 17, 1999, a Beech 99A (registration N133BA) was involved in an aviation accident near Bemidji, MN. Investigators recorded the probable cause as: Failure of the left main landing gear actuator for undetermined reasons. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
After takeoff, a red warning light in the landing gear handle failed to extinguish. The pilot recycled the gear and manually pumped it down, but during landing the left main gear collapsed after reverse thrust application.
Event Sequence
The pilot reported that after takeoff and raising the landing gear, the red warning light in the landing gear handle failed to go out. The pilot recycled the landing gear, but could not get the red light to extinguish. On return to the airport, the pilot lowered the landing gear handle down, but nothing happened. He recycled the handle two additional times with no results. The pilot overflew the airport and confirmed that the landing gear were still up. He then manually pumped the landing gear down. Only the nose gear and right main gear green indicator lights illuminated. The pilot overflew the airport again and was told that the three gear were down.
Landing
During the landing, the pilot touched down on the right main gear first, and then gently lowered the left main gear to the runway. The landing gear held initially. As the pilot applied reverse thrust, the left main gear suddenly collapsed. The airplane slid off the left side of the runway and came to a stop in the grass.
Post-Landing Examination
Examination of the airplane revealed no anomalies.
