2023-22-08: Fuselage

1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. 2. The FAA amends § 39.13 by: a. Removing Airworthiness Directive (AD) 2023-04-12, Amendment 39-22359 (88 FR 12143, February 27, 2023); and b. Adding the following new AD: 2023-22-08 Airbus SAS: Amendment 39-22592; Docket No. FAA-2023-2142; Project Identifier MCAI-2023-01056-T. (a) Effective Date This airworthiness directive (AD) is effective November 20, 2023. (b) Affected ADs This AD replaces AD 2023-04-12, Amendment 39-22359 (88 FR 12143, February 27, 2023) (AD 2023-04-12). (c) Applicability This AD applies to all Airbus SAS Model A350-941 and -1041 airplanes, certificated in any category. (d) Subject Air Transport Association (ATA) of America Code 53, Fuselage. (e) Unsafe Condition This AD was prompted by the migration of cargo sealing tape from its original position between the cargo floor panels and the cargo loading system in the longitudinal direction in the forward and aft cargo compartment area, and between the cargo floor panels and the floor structure in the transversal direction in the bulk cargo compartment area at frame 82. The FAA is issuing this AD to address this tape migration, which can affect the tightness of the cargo compartment floor panels that provide an enclosed area to maintain halon concentration in the event of a fire. This condition, if not addressed, could affect the fire extinguishing system efficiency in the cargo compartments, possibly resulting in failure of the system to contain a cargo compartment fire or permanently extinguish a fire. (f) Compliance Comply with this AD within the compliance times specified, unless already done. (g) Requirements Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2023-0176, dated October 6, 2023 (EASA AD 2023-0176). (h) Exceptions to EASA AD 2023-0176 (1) Where EASA AD 2023-0176 refers to "31 January 2023 [the effective date of EASA AD 2023-0011]," this AD requires replacing those words with "March 14, 2023 (the effective date of AD 2023-04-12)." (2) Where EASA AD 2023-0176 refers to its effective date, this AD requires using the effective date of this AD. (3) Where paragraph (2) of EASA AD 2023-0176 specifies accomplishing corrective actions if "discrepancies, as identified in the AOT" are found, for this AD, discrepancies are defined as cargo sealing tape that has migrated more than 11 millimeters, complete migration of the tape as shown in Condition B of the service information reference in EASA AD 2023-0176, incorrect seating/condition of the tape in repaired areas, and incorrect sealant condition in repaired areas. (4) Where paragraph (2) of EASA AD 2023-0176 specifies accomplishing corrective actions "in accordance with the instructions of the AOT," for this AD, replace those words with "in accordance with the instructions of the AOT for the FWD and AFT cargo compartment areas and in accordance with the instructions of Airbus AOT A53P016-22, Revision 03, dated September 13, 2023, or later approved revisions for the BULK cargo compartment areas." (5) Where the service information referenced in EASA AD 2023-0176 specifies use of cargo sealing tape 398FR, this AD also allows use of cargo sealing tape 398FRP. (6) This AD does not adopt the "Remarks" section of EASA AD 2023-0176.

(3) Required for Compliance (RC): Except as required by paragraph (i)(2) of this AD, if any service information referenced in EASA AD 2023-0176 that contains paragraphs that are labeled as RC, the instructions in RC paragraphs, including subparagraphs under an RC paragraph, must be done to comply with this AD; any paragraphs, including subparagraphs under those paragraphs, that are not identified as RC are recommended.
