Adoption of 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 removing airworthiness directive (AD) 2018-25-04, Amendment 39-19515 (83 FR 63397, December 10, 2018), and adding the following new AD: \n\n2020-09-10 Airbus Canada Limited Partnership (Type Certificate previously held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.): Amendment 39-19906; Docket No. FAA-2020-0349; Product Identifier 2020-NM-027-AD. \n\n(a) Effective Date \n\n\n\tThis AD is effective May 26, 2020. \n\n(b) Affected ADs \n\n\n\tThis AD replaces AD 2018-25-04, Amendment 39-19515 (83 FR 63397, December 10, 2018) (''AD 2018-25-04''). \n\n(c) Applicability \n\n\n\tThis AD applies to AirbusCanada Limited Partnership (Type Certificate previously held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) airplanes, certificated in any category, identified in paragraphs (c)(1) and (2) of this AD. \n\t(1) Model BD-500-1A10 airplanes, serial numbers 50001 through 50017 inclusive, equipped with blow-out panel part number D762213- 503, D762216-505, or D762209-503. \n\t(2) Model BD-500-1A11 airplanes, serial numbers 55001 through 55044 inclusive, equipped with blow-out panel part number D762213- 503, D762216-505, or D762209-503. \n\n(d) Subject \n\n\n\tAir Transport Association (ATA) of America Code 50, Cargo and accessory compartment. \n\n(e) Reason \n\n\n\tThis AD was prompted by reports of dislodged cargo compartment blow-out panels. This AD was also prompted by a panel redesign that decreases the likelihood of dislodgement due to baggage impact, and by the determination that the repetitive inspection interval may be extended, based on in-service findings. The FAAis issuing this AD to address dislodged cargo compartment blow-out panels, which could result in openings in the forward and aft cargo compartments. In the event of a cargo compartment fire, these unintended openings in the forward and aft cargo compartments would provide a path for smoke, fire, and Halon to enter the adjacent equipment bays, flight deck, and passenger cabin, which could delay smoke detection in the forward and aft cargo compartments and result in the forward and aft cargo compartments not being able to maintain the Halon concentration required for fire suppression. The cargo compartment fire may become uncontrollable if this condition is not addressed, which could result in the loss of controllability of the airplane. \n\n(f) Compliance \n\n\n\tComply with this AD within the compliance times specified, unless already done. \n\n(g) Retained Repetitive Inspections of the Forward and Aft Cargo Compartment Blow-Out Panels and Re-Installation, With Revised Repetitive Inspection Interval \n\n\n\tThis paragraph restates the requirements of paragraph (g) of AD 2018-25-04, with a revised repetitive inspection interval. Within 7 days or 50 flight cycles, whichever occurs first, after January 14, 2019 (the effective date of AD 2018-25-04): Do a detailed inspection for any dislodged blow-out panel in the forward and aft cargo compartments, in accordance with C Series (Bombardier) Data \n\n((Page 27673)) \n\nModule BD500-A-J50-10-01-01AAA-310B-A, ''Forward and aft cargo compartment blow-out panels--Visual check,'' Issue 002, dated May 16, 2018. Re-install all dislodged forward and aft cargo compartment blow-out panels before further flight, in accordance with C Series (Bombardier) Data Module BD500-A-J50-10-01-00AAA-521A-A, ''Decompression panels dislodging--Return to basic configuration,'' Issue 002, dated May 16, 2018. Thereafter, at intervals not to exceed 200 flight cycles, repeat the detailed inspection for any dislodged blow-out panel in the forward and aftcargo compartments. \n\n(h) New Requirement of This AD: Blow-Out Panel Replacement \n\n\n\tWithin 9,350 flight hours or 56 months, whichever occurs first, after the date of issuance of the original airworthiness certificate or date of issuance of the original export certificate of airworthiness: Install new, redesigned sidewall and bulkhead panel assemblies in the forward and aft cargo compartments, in accordance with Airbus Canada Limited Partnership A220 Service Bulletin BD500- 500001, Issue 002, dated October 28, 2019. \n\n(i) No Reporting Requirement \n\n\n\tAlthough reporting was required in AD 2018-25-04, this AD does not include that requirement. \n\n(j) New Terminating Action for Repetitive Inspections \n\n\n\tModification of an airplane as required by paragraph (h) of this AD constitutes terminating action for the initial and repetitive inspections required by paragraph (g) of this AD for that airplane. \n\n(k) Credit for Previous Actions \n\n\n\tThis paragraph provides credit for actions required by paragraph (h) of this AD, if those actions were performed before the effective date of this AD using Bombardier C Series Service Bulletin BD500- 500001, Issue 001, dated February 18, 2019. \n\n(l) Other FAA AD Provisions \n\n\n\tThe following provisions also apply to this AD: \n\t(1) Alternative Methods of Compliance (AMOCs): The Manager, New York ACO Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.
