Airworthiness Directive · Amendment 39-21015 · Embraer S.A. Airplanes
Embraer S.A. Airplanes
Superseded. A later AD replaced this one: AD 2022-25-07. Comply with the one in force.
This AD applies to Embraer S.A. Model ERJ 170-100 LR, -100 STD, -100 SE, and -100 SU airplanes; and Model ERJ 170-200 LR, -200 SU, -200 STD, and -200 LL airplanes; certificated in any category; manufacturer serial numbers 17000002, 17000004 through 17000013 inclusive, and 17000015 through 17000761 inclusive.
The FAA is superseding Airworthiness Directive (AD) 2017-06- 08, which applied to certain 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. AD 2017-06-08 required revising the existing maintenance or inspection program, as applicable, to incorporate more restrictive airworthiness limitations. This AD continues to require that revision; adds a new requirement for revising the existing maintenance or inspection program, as applicable, to incorporate new or more restrictive airworthiness limitations; and adds airplanes to the applicability. Since the FAA issued AD 2017-06-08, the agency determined that new or more restrictive airworthiness limitations are necessary. The FAA is issuing this AD to address the unsafe condition on these products.
This paragraph restates the requirements of paragraph (i) of AD 2017-06-08, with no changes. For 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; manufacturer serial numbers 17000002, 17000004 through 17000013 inclusive, and 17000015 through 17000453 inclusive: Within 12 months after May 11, 2017 (the effective date of AD 2017-06-08), revise the existing maintenance or inspection program, as applicable, to incorporate the airworthiness limitations specified in Part 1—Certification Maintenance Requirements (CMR); Part 2—Airworthiness Limitation Inspections (ALI)-Structures; Part 3—Fuel System Limitation Items (FSL); and Part 4—Life Limited Items (LLI); of Appendix A—Airworthiness Limitations; of the EMBRAER 170/175 Maintenance Review Board Report (MRBR), MRB-1621, Revision 10, dated February 23, 2015. The initial compliance times and repetitive intervals are specified in the applicable part of the EMBRAER 170/175 MRBR, MRB-1621, Revision 10, dated February 23, 2015.
This paragraph restates the action required by paragraph (j) of AD 2017-06-08, with a new exception. Except as required by paragraph (i) of this AD, after accomplishing the revisions required by paragraph (g) of this AD, no alternative actions (e.g., inspections), intervals, or CDCCLs may be used unless the actions, intervals, and CDCCLs are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (k)(1) of this AD.
Within 90 days after the effective date of this AD, revise the existing maintenance or inspection program, as applicable, to incorporate the information specified in Part 1—Certification Maintenance Requirements, Part 2—Airworthiness Limitation Inspections (ALI)-Structures, Part 3—Fuel System Limitation Items, and Part 4—Life Limited Items; and EMBRAER Temporary Revision (TR) 14-1, dated November 13, 2018, to part 4—Life Limited Items; of Appendix A of the EMBRAER 170/175 MRBR, MRB-1621, Revision 14, dated September 27, 2018 (“EMBRAER 170/175 MRB-1621, Revision 14”). The initial compliance time for doing the tasks is at the later of the times specified in paragraphs (i)(1) and (2) of this AD. Accomplishing the revision required by this paragraph terminates the requirements of paragraph (g) of this AD.
(1) Within the applicable times specified in EMBRAER 170/175 MRB-1621, Revision 14. For the purposes of this AD, the initial compliance times (identified as “Threshold” or “T” in EMBRAER 170/175 MRB-1621, Revision 14) are expressed in “total flight cycles” or “total flight hours,” as applicable.
(2) Within 90 days or 600 flight cycles after the effective date of this AD, whichever occurs later.
After the existing maintenance or inspection program has been revised as required by paragraph (i) of this AD, no alternative actions (e.g., inspections), intervals, or CDCCLs may be used unless the actions, intervals, and CDCCLs are approved as an AMOC in accordance with the procedures specified in paragraph (k)(1) 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.
