Abstract
This document corrects information in an existing airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model DC-9, DC-9-80 and C-9 (military) series airplanes, and Model MD-88 airplanes. The AD currently requires either the installation of external protective doublers between the outboard flight spoiler actuators and the aft spar webs of the wings, or replacement of the pistons of the outboard flight spoiler actuators with improved pistons. This action corrects a part number specified for flight spoiler actuator assembly that is acceptable for installation on these airplanes. This action is necessary to ensure that operators who previously have installed assemblies with this part number will be given proper credit for that installation, and will not be required to perform additional, unnecessary work to comply with the requirements of the AD.
