Construcciones Aeronauticas, S.A. (CASA) Model CN-235 Series Airplanes
Model CN-235 series airplanes, serial numbers C- 041 and C-042, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain CASA Model CN-235 series airplanes, that requires installation of fuselage skin reinforcements in the right and left zones of the fuselage between stations 11232 and 11740 and stringers P7 and P9. The actions specified by this AD are intended to prevent premature fatigue cracking of the fuselage, 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.
