Raytheon Aircraft Company 400A N800SD accident near Atlanta, Georgia

Probable cause

The collapse of the airplane’s left main landing gear during the landing roll for undetermined reasons.

NTSB analysis

After a normal landing, the left main landing gear collapsed during the landing roll, which resulted in the airplane impacting the runway on its left belly and dragging the left wing about 3,800 ft down the paved surface of the runway before coming to rest. The left wing sustained substantial damage. Postaccident operational testing of the airplane’s landing gear system revealed that the left main landing gear down lock actuator did not provide adequate pressure to lock the landing gear, which allowed the landing gear to retract upon landing. Visual examination of the actuator did not reveal any anomalies, and it was not leaking fluid. No additional examination of the left landing gear actuator was performed.
