Airworthiness Directive · Amendment 39-17940 · Nacelles/pylons
Empresa Brasileira de Aeronautica S.A. (Embraer) Airplanes
Superseded. A later AD replaced this one: AD 2021-25-02. Comply with the one in force.
This AD applies to all Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 ECJ, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes, certificated in any category.
We are adopting a new airworthiness directive (AD) for all Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 ECJ, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. This AD requires, for certain airplanes, retorquing and replacing the pylon outboard and inboard lower link fittings. For all airplanes, this AD requires repetitive retorquing of the pylon outboard and inboard lower link fittings. This AD was prompted by a report of a loose lower link assembly on the left and right pylons. We are issuing this AD to prevent loss of a shear pin on the pylon outboard and inboard lower link fittings, which could result in failure of the fitting and consequent separation of the engine from the wing.
Retorque the left and right pylon outboard and inboard lower link fittings, as specified in paragraph (g)(1) or (g)(2) of this AD, as applicable.
(1) For airplanes identified as Groups 1 and 2 in Embraer Service Bulletin 190-54-0015, dated July 3, 2014: Retorque at the applicable time specified in paragraph (g)(1)(i) or (g)(1)(ii) of this AD, in accordance with the Accomplishment Instructions of Embraer Alert Service Bulletin 190-54-A015, Revision 03, dated June 27, 2014.

(B) If, as of the effective date of this AD, the airplane has accumulated 600 or more total flight cycles or 750 or more total flight hours after accomplishment of Embraer Service Bulletin 190-54-0013: Retorque within 10 flight hours after the effective date of this AD.
(ii) For Group 2 airplanes: Retorque at the applicable time specified in paragraph (g)(1)(ii)(A) or (g)(1)(ii)(B) of this AD.
