2018-19-24: Time Limits/Maintenance Checks

Adoption of the Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: PART 39--AIRWORTHINESS DIRECTIVES 0 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. Sec. 39.13 [Amended] 0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive (AD): 2018-19-24 BAE Systems (Operations) Limited: Amendment 39-19425; Docket No. FAA-2018-0511; Product Identifier 2017-NM-145-AD. (a) Effective Date This AD is effective November 7, 2018. (b) Affected ADs This AD affects AD 2005-15-11, Amendment 39-14200 (70 FR 43025, July 26, 2005) (``AD 2005-15-11''). (c) Applicability This AD applies to all BAE Systems (Operations) Limited Model 4101 airplanes, certificated in any category, all manufacturer serial numbers. (d) Subject Air Transport Association (ATA) of America Code05, Time Limits/ Maintenance Checks. (e) Reason This AD was prompted by a determination that it is possible for cracks in fuselage frame 90 to exceed the critical length for failure in less time than the current inspection interval; and a determination that inspection requirements for a number of maintenance tasks involving certain airworthiness limitations are incorrect. We are issuing this AD to address cracking in fuselage frame 90, which could cause it to fail and thereby compromise the structural integrity of the aircraft pressure hull. We are also issuing this AD to address fatigue damage of various airplane structures, which could result in reduced structural integrity of the airplane. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Inspection At the compliance times specified in paragraphs (g)(1) and (g)(2) of this AD, as applicable: Do a detailed inspection of fuselage frame 90 for cracking orfatigue damage, in accordance with the Accomplishment Instructions of BAE Systems (Operations) Limited Alert Service Bulletin J41-A53-058, dated December 6, 2016. If any cracking or fatigue damage is found: Before further flight, repair using a method approved by the Manager, International Section, Transport Standards Branch, FAA; or the European Aviation Safety Agency (EASA); or BAE Systems (Operations) Limited's EASA Design Organization Approval (DOA). (1) For airplanes with 6,300 flight cycles or fewer since Structural Significant Items (SSI) 53-10-029 (Maintenance Planning Document (MPD) 531029-DVl-10010-1) was last accomplished: Within 6,600 flight cycles after the last accomplishment of SSI 53-10-029 (MPD 531029-DVl-10010-1), or within 6 months after the effective date of this AD, whichever is later. (2) For airplanes with more than 6,300 flight cycles since SSI 53-10-029 (MPD 531029-DVl-10010-1) was last accomplished: Within 300 flight cycles or 4.5 months, whichever is earlier, since the last accomplishment of SSI 53-10-029 (MPD 531029-DVl-10010-1), or within 6 months after the effective date of this AD, whichever is later. (h) Maintenance or Inspection Program Revisions Within 90 days after the effective date of this AD: Revise the maintenance or inspection program, as applicable, by incorporating the maintenance tasks and associated thresholds and intervals described in, and in accordance with, the Accomplishment Instructions of BAE Systems (Operations) Limited Service Bulletin J41-51-001, Revision 4, dated July 11, 2017. The initial compliance times for new or revised tasks are at the applicable times specified in BAE Systems (Operations) Limited Service Bulletin J41-51-001, Revision 4, dated July 11, 2017, or within 6 months after the effective date of this AD, whichever is later. (i) No Alternative Actions and Intervals After the maintenance or inspection program has been revised as required by paragraph (h) of this AD, no alternative actions (e.g., inspections) or intervals may be used unless the actions or intervals are approved as an alternative method of compliance (AMOC) in accordance with the procedures specified in paragraph (l)(1) of this AD. (j) Terminating Action for Requirements of AD 2005-15-11 Accomplishment of the actions required by paragraph (h) of this AD terminates all requirements of AD 2005-15-11. (k) No Reporting Requirement Although the Accomplishment Instructions of BAE Systems (Operations) Limited Alert Service Bulletin J41-A53-058, dated December 6, 2016, specify to submit certain information to the manufacturer, this AD does not include that requirement. (l) Other FAA AD Provisions The following provisions also apply to this AD: (1) Alternative Methods of Compliance (AMOCs): The Manager, International Section, Transport Standards Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or local Flight Standards District Office, as appropriate. If sending information directly to the International Section, send it to the attention of the person identified in paragraph (m)(2) of this AD. Information may be emailed to: 9-ANM-116-AMOC- [[Page 49789]] [email protected]. Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the local flight standards district office/ certificate holding district office. (2) Contacting the Manufacturer: For any requirement in this AD to obtain corrective actions from a manufacturer, the action must be accomplished using a method approved by the Manager, International Section, Transport Standards Branch, FAA; or EASA; or BAE Systems (Operations) Limited's EASA DOA. If approved by the DOA, the approval must include the DOA-authorized signature.
