If you've not performed this Service Letter item it involves replacing existing solid head bolts with drilled head bolts that can be safety wired. We found our MLG actuator bolts were backing out(1st photo below) so performed the Service Letter. New drilled head AN175H22A bolts(2nd photo below) can be sourced at Military Fasteners https://military-fasteners.com/
