Airworthiness Directive · Amendment 39-13042 · Dornier Model 328-100 and -300 Series Airplanes
Dornier Model 328-100 and -300 Series Airplanes
Airplanes listed in Table 1 of this AD, certificated in any category. Table 1 follows: Table 1.--Applicability Model Serial numbers 328-100 series airplanes..................... 3005 through 3119 inclusive. 328-300 series airplanes..................... 3105 through 3196, excluding 3192 through 3194, inclusive.
This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-100 and -300 series airplanes, that requires replacement of the screws in the aileron, rudder, and elevator trim tabs with new screws; and removal and re-installation of screws in the aileron, elevator, and rudder trim tabs and the rudder spring tab; as applicable. This action is necessary to prevent reduced structural integrity of the screws in the aileron, elevator, and rudder trim tabs and the rudder spring tab, due to countersinks that were not manufactured correctly, which could result in 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.
