The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to certain McDonnell Douglas Model DC-9, DC-9-80, and C-9 (military) series airplanes; Model MD-88 airplanes; and Model MD-90 airplanes, that requires a one-time inspection of the forward attach pins of the outboard flight spoiler actuators to determine whether the pins are of correct length, and follow-on corrective actions. This amendment is prompted by a report that forward attach pins of incorrect length were found to be installed in the flight spoiler actuators on several in-service and in-production airplanes. The actions specified by this AD are intended to prevent failure of the piston of the flight spoiler actuator and consequent puncturing of the aft spar web, which could result in fuel leakage and reduced structural integrity of the wings.
