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.
The article details multiple incidents of landing gear failures across various aircraft types, including collapses during landing/rollout and unsuccessful retraction or extension attempts.
Causes for these failures are diverse, ranging from structural component damage (e.g., actuator supports, mounting points, fasteners, elongated holes) and hydraulic system deficiencies (e.g., low fluid levels) to operational factors like specific rudder inputs during retraction.
Several cases highlight the ineffectiveness of emergency extension procedures in preventing gear collapse and the challenges in identifying underlying issues such as inaccessible fluid reservoirs or subtle structural wear like fretting corrosion.
