Incident Overview
During a night approach to land, the right main landing gear of an aircraft struck a semi-trailer truck as the aircraft crossed over a highway. The centerline of the highway was located approximately 102 feet from the approach end of the runway. The pilot continued the landing, and the right main gear collapsed during the landing roll.
Investigation Findings
An investigation revealed that the right main gear hit the top of the truck cab, which was 9 feet 7 inches above ground level. The impact damaged the cab, windshield, and vertical exhaust stack of the truck.
Runway Environment
The runway was 4,350 feet long and had a 750-foot displaced threshold. No Visual Approach Slope Indicator (VASI) lights were installed.
Sequence of Events
The aircraft was on final approach in darkness when it passed over the highway, leading to contact with the truck. After the collision, the aircraft landed but the right main gear failed, collapsing during the rollout.
