Crew observed right main landing gear unsafe indication on extension at destination. Emergency gear extension procedures did not result in safe indication. After landing, right main gear collapsed as aircraft came to a stop. Significant damage was discovered to the right main gear actuator support structure.
Landing gear failures stem from diverse issues, including structural damage (actuator supports, mounting points, fasteners), hydraulic system problems (low fluid), and operational interactions.
These failures commonly lead to gear collapse during landing or rollout, often resulting in significant aircraft damage.
Detection challenges exist, such as inaccessible hydraulic fluid reservoirs during pre-flight checks or intermittent issues that technicians cannot replicate.
Recurring factors in gear collapses include structural integrity problems like elongated bolt holes, broken fasteners, and fretting corrosion.
