Airworthiness Directive · Amendment 39-19429 · Nacelles/pylons
Embraer S.A. Airplanes
Superseded. A later AD replaced this one: AD 2021-25-02. Comply with the one in force.
This AD applies to the Embraer S.A. airplanes identified in paragraphs (c)(1) and (c)(2) of this AD, certificated in any category.
(1) Model ERJ 190-100 STD, -100 LR, and -100 IGW airplanes; and Model ERJ 190-200 STD, -200 LR, and -200 IGW airplanes; as identified in Embraer Service Bulletin 190-54-0016, Revision 04, dated December 7, 2017.
(2) Model ERJ 190-100 ECJ airplanes as identified in Embraer Service Bulletin 190LIN-54-0008, Revision 02, dated May 9, 2018.
We are adopting a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 ECJ, and -100 IGW airplanes; and Model ERJ 190-200 STD, -200 LR, and -200 IGW airplanes. This AD was prompted by reports of bushing migration and loss of nut torque on the engine pylon lower inboard and outboard link fittings. This AD requires modification of the attaching parts of the left-hand (LH) and right-hand (RH) pylon lower link fittings, inboard and outboard positions. We are issuing this AD to address the unsafe condition on these products.
