Airworthiness Directive · Amendment 39-13031 · Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-145 Series Airplanes
Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-145 Series Airplanes
Model EMB-145 series airplanes, serial numbers 145004 through 145058 inclusive, and 145060; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain EMBRAER Model EMB-145 series airplanes, that requires the installation of reinforcements in the lower portion of wing rib 15 on the left-hand and right-hand sides of the airplane. 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 reduced structural integrity of the wing flap support structure.
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.
