Airworthiness Directive · Amendment 39-13158 · Raytheon Model Beech 400A and 400T Series Airplanes
Raytheon Model Beech 400A and 400T Series Airplanes
Model Beech 400A series airplanes, serial numbers RK-232 through RK-265 inclusive; and Model Beech 400T series airplane having serial number TX-10; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Raytheon Model Beech 400A and 400T series airplanes, that requires replacement of the low-pressure oxygen tubing located in the forward fuselage (nose avionics bay), lower forward flight deck, and lower forward cabin areas, as applicable, with new low-pressure oxygen tubing. This action is necessary to prevent leakage of oxygen from scored low-pressure oxygen tubing, which could result in lack of available oxygen for the flightcrew, or possible explosion or fire. 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.
