Just wanted to provide an update as I received a reply from the FAA regarding the FOIA request I made to get the metallurgy report for the landing gear actuator gears. The FAA stated that the type holder will not provide the information and that the FAA has no means of requiring them to do so, nor does the FAA have a means of requiring the type hold to provide replacement parts in order comply with ADs or SBs, even if the type holder has the capability to produce the parts, which they do.
