Airworthiness Directive · Amendment 39-13460 · Dornier Model 328-300 Series Airplanes
Dornier Model 328-300 Series Airplanes
Model 328-300 series airplanes as listed in Dornier Service Bulletins SB-328J-26-156 and SB-328J-26-161, both dated February 26, 2002; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Dornier Model 328-300 series airplanes, that requires replacement of 3-switch and 4-switch overhead fire extinguisher control panels with new, improved panels. This action is necessary to prevent the inadvertent release of the fire switch pushbutton on the overhead fire extinguisher control panel with the switch guard closed, which could result in an uncommanded engine shutdown. 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.
