## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Dornier Model 328-100 series airplanes, equipped with ground spoiler actuators having part number 1059A0000-02. This proposal would require removal of the gland attachment bolts of the ground spoiler actuator and replacement with new bolts installed with higher torque. 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 hydraulic fluid leakage due to loose or broken gland attachment bolts, and consequent loss of the main hydraulic system.
