Airworthiness Directive · Amendment 39-18256 · Fuel
Empresa Brasileira de Aeronautica S.A. (Embraer) Airplanes
This AD applies to all Empresa Brasileira de Aeronautica S.A. (Embraer) Model EMB-135BJ airplanes, certificated in any category.
We are adopting a new airworthiness directive (AD) for all Empresa Brasileira de Aeronautica S.A. (Embraer) Model EMB-135BJ airplanes. This AD was prompted by a determination that more restrictive fuel limitations are needed. This AD requires revising the maintenance or inspection program to incorporate new compliance times and fuel limitations. We are issuing this AD to detect and correct fatigue cracking of various structural elements and prevent ignition sources in the fuel system.
Within 60 days after the effective date of this AD, do the actions specified in paragraphs (g)(1), (g)(2), and (g)(3) of this AD.
(1) Revise the maintenance or inspection program, as applicable, by incorporating the Critical Design Configuration Control Limitations (CDCCLs) specified in Embraer Temporary Revision (TR) 8-1, dated October 26, 2012, to the Embraer Legacy BJ Maintenance Planning Document (MPG), MPG-1483, into Appendix 2, “Airworthiness Limitations Requirements,” of the Embraer Legacy BJ MPG, MPG-1483.
(2) Revise the maintenance or inspection program, as applicable, by incorporating the tasks and compliance times specified in Embraer TR 8-3, dated April 8, 2013, of Embraer Legacy BJ MPG, MPG-1483; and Embraer TR 8-2, dated December 5, 2012, to the Embraer Legacy BJ MPG, MPG-1483; into Appendix 2, “Airworthiness Limitations Requirements,” of the Embraer Legacy BJ MPG, MPG-1483. The initial compliance times for the tasks start at the applicable time specified in Embraer TR 8-2, dated December 5, 2012, and TR 8-3, dated April 8, 2013; or within 500 flight cycles after the effective date of this AD, whichever occurs later. Where Embraer TR 8-2, dated December 5, 2012, specifies a compliance time in “flight cycles” for the pre-mod service bulletin, those compliance times are total flight cycles.
(3) Revise the maintenance or inspection program, as applicable, by incorporating the new fuel system limitations specified in Embraer TR 8-1, dated October 26, 2012, to the Embraer Legacy BJ MPG, MPG-1483, into Appendix 2, “Airworthiness Limitations Requirements,” of the Embraer Legacy BJ MPG, MPG-1483. The initial compliance times for the tasks are specified in paragraphs (g)(3)(i) and (g)(3)(ii) of this AD.
(i) For tasks with reference numbers 28-50-01-220-001-A02, 28-50-08-212-001-A00, 28-50-09-212-001-A00, and 28-50-10-212-001-A00, at the later of the times specified in paragraph (g)(3)(i)(A) or (g)(3)(i)(B) of this AD.
(A) Before the accumulation of 10,000 total flight hours or within 48 months since the date of issuance of the original Brazilian standard airworthiness certificate or date of issuance of the original Brazilian export certificate of airworthiness, whichever occurs first.
(B) Within 60 months after the effective date of this AD.
(ii) For task reference number 28-50-01-720-001-A00, at the later of the times specified in paragraph (g)(3)(ii)(A) or (g)(3)(ii)(B) of this AD.
(A) Before the accumulation of 20,000 total flight hours or within 96 months since the date of issuance of the original Brazilian standard airworthiness certificate or date of issuance of the original Brazilian export certificate of airworthiness, whichever occurs first.
(B) Within 60 months after the effective date of this AD.
When the information from Embraer TR 8-1, dated October 26, 2012; TR 8-2, dated December 5, 2012; and TR 8-3, dated April 8, 2013; to the Embraer Legacy BJ MPG, MPG-1483, has been included in the general revisions of Embraer Legacy BJ MPG, MPG-1483, the general revisions may be inserted in the MPG, provided that the relevant information in the general revision is identical to that in Embraer TR 8-1, dated October 26, 2012; TR 8-2, dated December 5, 2012; and TR 8-3, dated April 8, 2013; and the TRs may be removed.
After accomplishing the revision required by paragraph (g) of this AD, no alternative actions (e.g., inspections), intervals, and/or CDCCLs may be used unless the actions, intervals, and/or CDCCLs are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (j)(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.
