Airworthiness Directive · Amendment 39-12063 · Dornier Model 328-300 Series Airplanes
Dornier Model 328-300 Series Airplanes
All Model 328-300 series airplanes, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to all Dornier Model 328-300 series airplanes. This action requires inspections of all three hydraulic accumulators for signs of leaks, corrective actions if necessary, and eventual installation of an additional locking device to secure the nuts in the hydraulic accumulators, which will terminate the repetitive inspections. This action is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. This action is necessary to prevent possible loss of one or more of the hydraulic accumulators, which could result in a complete loss of the hydraulic system and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
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.
