Construcciones Aeronauticas, S.A. (CASA) Model CN-235 Series Airplanes
Model CN-235 series airplanes; as listed in CASA Service Bulletins SB-235-57-14, Revision 1, dated June 21, 1996; and SB-235-57-05, Revision 2, dated June 21, 1996, including Annex 1, dated June 10, 1993; and Model CN-235 having serial number C-011; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain CASA Model CN-235 series airplanes, that requires modification of certain fastener holes of the center wing. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent fatigue cracking in this area, which could result in reduced structural integrity of the wing.
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.
