Airworthiness Directive · Amendment 39-16319 · Fuselage
Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 190-100 STD, -100 LR, -100 IGW, -200 STD, -200 LR, and -200 IGW Airplanes
Superseded. A later AD replaced this one: AD 2012-23-09. Comply with the one in force.
This AD applies to all Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model ERJ 190-100 STD, -100 LR, -100 IGW, -200 STD, -200 LR, and -200 IGW airplanes, certificated in any category.
Note 1: This AD requires revisions to certain operator maintenance documents to include new inspections. Compliance with these inspections is required by 14 CFR 91.403(c). For airplanes that have been previously modified, altered, or repaired in the areas addressed by these inspections, the operator may not be able to accomplish the inspections described in the revisions. In this situation, to comply with 14 CFR 91.403(c), the operator must request approval for an alternative method of compliance according to paragraph (g)(1) of this AD. The request should include a description of changes to the required inspections that will ensure the continued operational safety of the airplane.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions.
(1) Within 90 days after the effective date of this AD: Revise the ALS of the ICA to include the tasks specified in Table 1 of this AD. These tasks are identified in EMBRAER Temporary Revision (TR) 2-5, dated December 6, 2007; and EMBRAER TR 2-6, dated February 12, 2008; to Appendix A, Part 2, Airworthiness Limitation Inspections (ALI)—Structures, of the EMBRAER 190 Maintenance Review Board Report (MRBR) MRB-1928.
Note 2: The actions required by paragraph (f)(1) of this AD may be done by inserting a copy of EMBRAER TR 2-5 and TR 2-6 into the ALS of the EMBRAER 190 MRBR MRB-1928. When these TRs have been included in general revisions of the EMBRAER 190 MRBR MRB-1928, the general revisions may be inserted in the EMBRAER 190 MRBR MRB-1928, provided the relevant information in the general revision is identical to that in EMBRAER TR 2-5 and TR 2-6, and these TRs may be removed.
(2) The initial compliance times for the tasks specified in EMBRAER TR 2-5, dated December 6, 2007; and EMBRAER TR 2-6, dated February 12, 2008; to Appendix A, Part 2, Airworthiness Limitation Inspections (ALI)—Structures, of the EMBRAER 190 MRBR MRB-1928; start at the later of the times specified in paragraphs (f)(2)(i) and (f)(2)(ii) of this AD. For certain tasks, the compliance times depend on the pre-modification and post-modification condition of the associated service bulletin, as specified in the “Applicability” column of these TRs.
(i) Within the applicable threshold times specified in these TRs.
(ii) At the applicable compliance time specified in Table 1 of this AD.
| EMBRAER MRBR TR | Subject | MRBR task No. | Compliance time |
|---|---|---|---|
| TR 2-5, dated December 6, 2007 | Wing stub main box lower skin and splices—internal | 57-01-002-0002 | 250 flight cycles after effective date of this AD. |
| TR 2-5, dated December 6, 2007 | Wing stub spar 3—internal/external | 57-01-008-0003 | 500 flight cycles after effective date of this AD. |
| TR 2-5, dated December 6, 2007 | Wing stub spar 3—external | 57-01-008-0004 | 500 flight cycles after effective date of this AD. |
| TR 2-5, dated December 6, 2007 | Wing lower skin panel stringers—internal | 57-10-007-0004 | 500 flight cycles after effective date of this AD. |
| TR 2-5, dated December 6, 2007 | Wing main box rib 11—internal | 57-10-012-0003 | 500 flight cycles after effective date of this AD. |
| TR 2-6, dated December 12, 2008 | Nose landing gear wheel well metallic structure | 53-10-021-0004 | 500 flight cycles after effective date of this AD. |
(iii) Thereafter, except as provided in paragraph (g) of this AD, no alternative replacement times or structural inspection intervals may be approved for these tasks.
Note 3: This AD differs from the MCAI and/or service information as follows: Although the MCAI specifies both revising the airworthiness limitations and doing repetitive inspections, this AD only specifies the revision. Requiring revision of the airworthiness limitations, rather than requiring individual repetitive inspections, is advantageous for operators because it allows them to record AD compliance status only at the time that they make the revision, rather than after every inspection. It also has the advantage of keeping all airworthiness limitations, whether imposed by original certification or by AD, in one place within the operator's maintenance program, thereby reducing the risk of non-compliance because of oversight or confusion.
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.
