## Summary

This document proposes the supersedure of an existing airworthiness directive (AD), applicable to all Dornier Model 328-100 series airplanes, that currently requires repetitive inspections of the left and right roll spoiler actuators to check for signs of leakage and deformation of the housing, repetitive inspections of the gap between the left roll spoiler actuator housing cap and the actuator housing, repetitive torque checks of the left roll spoiler actuator housing cap attachment screws, and corrective action, if necessary. This action would require replacement of the double shuttle valves in the roll spoiler actuators with new improved valves. Accomplishment of the proposed replacement would constitute terminating action for the requirements of this AD. This proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by the proposed AD are intended to prevent oil leakage from the rollspoiler actuators, which could result in incorrect roll spoiler operation and reduced controllability of the airplane.
