What happened
During the landing roll, the pilot reported that the right wing of the aircraft settled to the runway surface. The incident occurred while the airplane was decelerating on the ground after touchdown.
The investigation
A post-incident examination of the airplane revealed a mechanical failure within the landing gear system. Specifically, the pivot link connecting the push-pull tubes to the over-center link assembly had failed. This structural failure prevented the landing gear from maintaining its extended position or absorbing the load correctly during the ground phase of the flight.
Findings
A repair station was employed to inspect and repair the aircraft following the incident. During their assessment of the landing gear system rigging, technicians determined that the assembly was found to be out of tolerance. This misalignment likely contributed to the stress that led to the pivot link failure, resulting in the right wing settling onto the runway during the landing roll.
