Airworthiness Directive · Amendment 39-19080 · Fuselage
Embraer S.A. Airplanes
This AD applies to the airplanes specified in paragraphs (c)(1) and (c)(2) of this AD, certificated in any category.
(1) 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; as identified in Embraer Service Bulletin 170-53-0051, Revision 03, dated August 21, 2013.
(2) Embraer S.A. 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 190-53-0019, Revision 03, dated August 21, 2013.
We are adopting a new airworthiness directive (AD) for certain Embraer S.A. Model ERJ 170 airplanes and Model ERJ 190-100 STD, -100 LR, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes. This AD was prompted by an evaluation by the design approval holder indicating that the forward pressure bulkhead is subject to widespread fatigue damage. This AD requires repetitive detailed inspections of the web aft face of the forward pressure bulkhead for any cracking and discrepancy, and repair if necessary. This AD also requires modification of the forward pressure bulkhead, which would terminate the inspections. We are issuing this AD to address the unsafe condition on these products.
Before the accumulation of 25,954 total flight cycles, or within 3,600 flight cycles after the effective date of this AD, whichever occurs later: Do a detailed inspection of the web aft face of the forward pressure bulkhead for any cracking and discrepancy (i.e., corrosion, dents, gauge marks, fastener anomalies), in accordance with Task 53-10-001-0005 specified in Embraer 170/175 MRB—Temporary Revision 12-3, dated September 19, 2016, to the Embraer 170/175 Maintenance Review Board Report, MRB-1621; or Task 53-10-001-0005 specified in Embraer 190/195 MRB—Temporary Revision 10-4, dated September 19, 2016, to the Embraer 190/195 Maintenance Review Board Report, MRB-1928; as applicable. Repeat the inspection thereafter at intervals not to exceed 6,489 flight cycles. If any cracking or discrepancy is found during any inspection required by this paragraph, before further flight, repair the forward pressure bulkhead using a method approved by the Manager, International Section, Transport Standards Branch, FAA; or the Agência Nacional de Aviação Civil (ANAC); or ANAC's authorized Designee. If approved by the ANAC Designee, the approval must include the Designee's authorized signature.
Before the accumulation of 38,931 total flight cycles: Modify the forward pressure bulkhead, in accordance with the Accomplishment Instructions of Embraer Service Bulletin 170-53-0051, Revision 03, dated August 21, 2013; or Embraer Service Bulletin 190-53-0019, Revision 03, dated August 21, 2013; as applicable. Accomplishing the modification required by this paragraph terminates 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.
