2020-26-19: Time Limits/Maintenance Checks

The Amendment \n\n\n\tAccordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: \n\nPART 39--AIRWORTHINESS DIRECTIVES \n\n0 1. The authority citation for part 39 continues to read as follows: \n\n\n\tAuthority: 49 U.S.C. 106(g), 40113, 44701. \n\n\n\nSec. 39.13 (Amended) \n\n0 2. The FAA amends Sec. 39.13 by adding the following new airworthiness directive: \n\n2020-26-19 Pilatus Aircraft Ltd: Amendment 39-21374; Docket No. FAA- 2020-0849; Project Identifier MCAI-2020-01036-A. \n\n(a) Effective Date \n\n\n\tThis airworthiness directive (AD) is effective March 29, 2021. \n\n(b) Affected ADs \n\n\n\tNone. \n\n(c) Applicability \n\n\n\tThis AD applies to Pilatus Aircraft Ltd. Model PC-7 airplanes, all serial numbers, certificated in any category. \n\n(d) Subject \n\n\n\tAir Transport Association (ATA) of America Code 05, Time Limits/ Maintenance Checks. \n\n(e) Reason \n\n\n\tThis AD was prompted by the need to revise the Airworthiness Limitation section of the existing aircraft maintenance manual (AMM). The FAA is issuing this AD to revise the Airworthiness Limitations section of the existing AMM to introduce new mandatory repetitive inspections for the flap pivot arm assemblies and for the wing angle brackets on middle rib 23, and to implement a change to \n\n((Page 10453)) \n\nthe Oxygen cylinder and pressure reducer task item. The unsafe condition, if not addressed, could result in reduced structural integrity and system reliability of the airplane. \n\n(f) Compliance \n\n\n\tUnless already done, before further flight: Incorporate the revised Airworthiness Limitation section as specified in Section 05- 10-10, ''Lifed and Overhauled Components,'' dated June 30, 2020, of Chapter 05, Time Limits/Maintenance Checks, of the Pilatus PC-7 Maintenance Manual, into the Airworthiness Limitations section of your FAA-accepted maintenance program (maintenance manual). \n\n(g) No Alternative Actions or Intervals \n\n\n\tAfter theAirworthiness Limitations section of the existing maintenance or inspection program has been revised as required by paragraph (f) 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 (h) of this AD. \n\n(h) Other FAA AD Provisions \n\n\n\tAMOCs: The Manager, International Validation Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.
