Airworthiness Directive · Amendment 39-12082 · Construcciones Aeronauticas, S.A. (CASA), Model CN-235, CN-235-100, and CN-235-200 Series Airplanes
Construcciones Aeronauticas, S.A. (CASA), Model CN-235, CN-235-100, and CN-235-200 Series Airplanes
All Model CN-235, CN-235-100, and CN-235-200 series airplanes, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to to all CASA Model CN-235, CN-235-100, and CN-235-200 series airplanes, that requires replacing the upper brackets in frames 33, 34, and 35, with improved brackets that are more fatigue resistant, and reinforcing frame 35. The actions specified by this AD are intended to prevent fatigue cracking in the zone of the fittings connecting the fuselage to stiffener rods located in frames 33, 34, and 35, which could result in reduced structural integrity 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.
