Airworthiness Directive · Amendment 39-16306 · Fuselage
Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135BJ, -135ER, -135KE, -135KL, -135LR, -145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP Airplanes
This AD applies to all Empresa Brasileira de Aeronautica S.A. (EMBRAER) Model EMB-135BJ, -135ER, -135KE, -135KL, -135LR, -145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes, certificated in any category, all serial numbers, except Model EMB-145LR airplanes that have been modified in accordance with Brazilian Supplemental Type Certificates 2002S06-09, 2002S06-10, and 2003S08-01.
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) 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. The FAA has provided guidance for this determination in Advisory Circular (AC) 25-1529-1.
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 Instructions for Continued Airworthiness to incorporate the structural inspection item (SSI) 53-10-19's applicable tasks identified in Appendix 2, “Airworthiness Limitation Requirements,” of the applicable document listed in Table 1 of this AD. The initial compliance times for the task start from the applicable time specified in SSI 53-10-19 or within 200 flight cycles after revising the ALS, whichever occurs later. Repeat the applicable inspection thereafter at the interval specified in Appendix 2 of the applicable document listed in Table 1 of this AD, except as provided by paragraphs (f)(2) and (g) of this AD.
| Model— | Appendix 2, “Airworthiness Limitation Requirements,” of EMBRAER— |
|---|---|
| EMB-135ER, -135KE, -135KL, -135LR, -145, -145ER, -145MR, -145LR, -145XR, -145MP, and -145EP airplanes | EMB135/EMB145 Maintenance Review Board Report (MRBR) MRB-145/1150, Revision 12, dated September 19, 2008. |
| EMB-135BJ airplanes | Legacy BJ—Maintenance Planning Guide MPG-1483, Revision 5, dated March 22, 2007. |
Note 2: Appendix 2, “Airworthiness Limitation Requirements,” of EMBRAER EMB135/EMB145 MRBR MRB-145/1150, Revision 12, dated September 19, 2008, includes EMBRAER Temporary Revision 10-6, dated May 23, 2007, which is referred to in the MCAI as an applicable document to incorporate into the maintenance program.
(2) After accomplishing the actions specified in paragraph (f)(1) of this AD, no alternative inspections or inspection intervals may be used unless the inspection or inspection interval is approved by the Manager, International Branch, ANM-116, Transport Airplane Directorate, FAA, or the Agência Nacional de Aviação Civil (ANAC) (or its delegated agent); or unless the inspection or interval is approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (g)(1) of this AD.
(3) Actions done before the effective date of this AD in accordance with EMBRAER EMB135/EMB145 MRBR MRB-145/1150, Revision 11, dated September 19, 2007, are acceptable for compliance with the corresponding requirements of this AD.
Note 3: This AD differs from the MCAI and/or service information as follows: (1) We have removed the requirement to mandate the SSI tasks in Section 4—“Structural Inspection Requirements,” of the applicable document listed in Table 1 of this AD which are referred to in the MCAI. Those SSI tasks are included in Appendix 2, “Airworthiness Limitation Requirements,” of the applicable document listed in Table 1 of this AD. (2) We have not included the 21,336-flight-cycle threshold specified in the MCAI because the airplanes in the U.S.-registered fleet have surpassed that threshold. Instead, we included a 200-flight-cycle grace period for accomplishing the SSI 53-10-19 tasks.
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.
