I've also had a recent failure of the MAC 6A. Mine did not completely
come apart but ceased to work because the gears no longer were making
contact. This was on a LCN2 so it just did not cause the wanted spring
tension etc. The back bearing plate pushed out as Jim
described. Earl
Upon inspection found the Mac 6A
trim motor housing to be broken. The main trim shaft that works the trim
tab had pushed the rear bearing plate out and scattered the gears inside the
elevator.
