Airworthiness Directive · Amendment 39-10552 · Dornier Model 328-100 Series Airplanes
Dornier Model 328-100 Series Airplanes
Model 328-100 series airplanes, serial numbers 3005 through 3095 inclusive; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-100 series airplanes, that requires replacement of the existing pressure dump and relief valves in the main and auxiliary hydraulic systems with new valves. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent failure of the pressure dump and relief valves in the main and auxiliary hydraulic systems, which could cause a loss in hydraulic pressure for roll control spoilers and brakes, and consequent reduced controllability of the airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
