Abstract
This amendment revises an existing airworthiness directive (AD), applicable to certain Boeing Model 727-100 and -200 series airplanes, that currently requires replacing the attaching nutplates on certain engine nose cowls with washers and self-locking nuts. This amendment changes the responsible office for approval of an alternative method of compliance. This amendment is prompted by the transfer of the supplemental type certificate. The actions specified in this AD are intended to prevent the attach bolts from becoming loose, which could result in subsequent separation of the nose cowl from the engine.
