Airworthiness Directive · Amendment 39-18563 · Pneumatic
Embraer S.A. Airplanes
This AD applies to the airplanes identified in paragraphs (c)(1) and (c)(2) of this AD, certificated in any category.
(1) All Embraer S.A. Model ERJ 170-100 LR, -100 STD, -100 SE., and -100 SU airplanes; and Model ERJ 170-200 LR, -200 SU, and -200 STD airplanes.
(2) All Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes.
We are adopting a new airworthiness directive (AD) for all Embraer S.A. Model ERJ 170 airplanes; and all Embraer S.A. Model ERJ 190-100 STD, -100 LR, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. This AD was prompted by reports of cracks in certain engine low-stage bleed check valves. This AD requires replacing the air management system (AMS) controller operation program of the AMS controller processor boards, and replacing the current low-stage bleed check valve and associated seals. We are issuing this AD to prevent failure of the low-stage bleed check valve; simultaneous failures of both low-stage bleed check valves could result in a dual engine in- flight shutdown.
For Embraer S.A. Model ERJ 190 airplanes identified in Embraer Service Bulletin 190-21-0041, Revision 02, dated July 30, 2013: Within 3 months after the effective date of this AD, replace the Hamilton Sundstrand air management system (AMS) controller operation program of the AMS controller processor boards, as specified in paragraph (g)(1) or (g)(2) of this AD.
(1) Replace with a new, improved program, in accordance with the Accomplishment Instructions of Embraer Service Bulletin 190-21-0041, Revision 02, dated July 30, 2013.
(2) Replace with a version of the Hamilton Sundstrand AMS controller operation program approved after August 31, 2012, using a method approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA; Agência Nacional de Aviação Civil (ANAC); or ANAC's authorized Designee.
For Embraer S.A. Model ERJ 190 airplanes identified in Embraer Service Bulletin 190-21-0041, Revision 02, dated July 30, 2013: Within 3 months after the effective date of this AD, and after accomplishment of the actions required by paragraph (g) of this AD, replace the check valve and associated seals of the left-hand and right-hand engine bleed system with a check valve identified in paragraph (i) of this AD, and new seals, in accordance with the Accomplishment Instructions of Embraer Service Bulletin 190-36-0023, Revision 03, dated September 24, 2014.
When complying with paragraph (h) of this AD, the low-stage bleed check valves having P/N 1001447-6, and associated seals, are replaced with new ones (zero-hour). Low-stage bleed check valves having P/N 1001447-6 that can be demonstrated with logged hours only on Model ERJ 170 airplanes and/or on Model ERJ 190 airplanes equipped with the AMS controller operational program version Black Label 13, or a later version, can be used instead of new ones (zero-hour).
(1) For Model ERJ 170-100 STD, -100 LR, -100SU, -100SE, -200 STD, -200 LR, and -200 SU airplanes: No person may install on any airplane a low-stage bleed check valve having P/N 1001447-6 that was installed on any Model ERJ 190-100 STD, -100 LR, -100 IGW, -200 STD, -200 LR, or -200 IGW airplane, any serial number except 190-00587, 190-00589, and 190-00593 and subsequent, prior to accomplishment of the requirements of paragraph (g) of this AD.
(2) For Model ERJ 190-100 STD, -100 LR, -100IGW, -200 STD, -200 LR, and -200 IGW airplanes: No person may install on any airplane on which the actions of paragraph (g) of this AD have been done, a low-stage bleed check valve having P/N 1001447-6 that was previously installed on any Model ERJ 190-100 STD, -100 LR, -100 IGW, -200 STD, -200 LR, or -200 IGW airplane, any serial number except 190-00587, 190-00589, 190-00593 and subsequent, prior to accomplishment of the requirements of paragraph (g) of this AD.
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.
