EASA 2011-0164R3

Supersedes but retains requirements of AD2011-0164R2, which mandated repetitive inspections of the tail rotor control stop screws and any necessary adjustment and introduced an optional modification (mod 074602) that would delete the need for repetitive inspections for post-mod 072295 helicopters. Revised AD limits the applicability, excluding post-mod 074819 helicopters, and introduces another optional modification (mod 074819) applicable to all helicopters that also eliminates the need for these repetitive inspections.
