Raytheon Aircraft Company Model 1900, 1900C, 1900C (C-12J), and 1900D Airplanes
The Federal Register printed this AD without its applicability text. Read it at the link below.
The FAA adopts a new airworthiness directive (AD) for certain Raytheon Aircraft Company (Raytheon) Model 1900, 1900C, 1900C (C-12J), and 1900D airplanes that do not have canted bulkhead Kit No. 129-4005-1 S incorporated. This AD requires you to repetitively inspect the canted bulkhead located at Fuselage Station (FS) 588.10 for cracks and incorporate canted bulkhead Repair Kit No. 129-4005-1 S anytime cracks are found. When Kit No. 129-4005-1 S is incorporated, the repetitive inspection requirement in this AD is terminated and no further action is required. This AD is the result of numerous reports of multi-site cracks occurring in the canted bulkhead at FS 588.10. We are issuing this AD to detect and correct cracks in the canted bulkhead. These cracks could result in failure of the bulkhead. Failure of the canted bulkhead could lead to loss of rudder and elevator control, which could result in loss of control 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.
