AD 2019-19-05

The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by reports of disconnections of certain hinge arms of the bulk cargo door (BCD) due to disbonding of the hinge arm bushes. This AD requires either modifying and re-identifying affected BCDs or replacing affected BCDs, as specified in a European Aviation Safety Agency (EASA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.

Final rule.

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):

2019-19-05 Airbus SAS: Amendment 39-19741; Docket No. FAA-2019-0401; Product Identifier 2019-NM-002-AD.

(a) Effective Date

This AD is effective November 13, 2019.

(b) Affected ADs

None.

(c) Applicability

This AD applies to all Airbus SAS Model A350-941 and -1041 airplanes, certificated in any category.

[[Page 54001]]

(d) Subject

Air Transport Association (ATA) of America Code 52, Doors.

(e) Reason

This AD was prompted by reports of disconnections of certain hinge arms of the bulk cargo door (BCD) due to disbonding of the hinge arm bushes. The FAA is issuing this AD to address disconnected hinge arms, which, in a case of ditching, could result in the BCD opening inward and allowing water into the cargo hold, and consequent reduced flotation time.

(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, EASA AD 2018-0243, dated November 8, 2018 (``EASA AD 2018-0243''). All provisions specified in EASA AD 2018-0243 apply in this AD.

Note 1 to paragraph (g): Instructions for re-identification of each affected BCD are provided in paragraph (2) of EASA AD 2018- 0243. They can also be found in Airbus Service Bulletin A350-52- P015, Revision 01, dated November 12, 2018.

(h) Exceptions to EASA AD 2018-0243

(1) For purposes of determining compliance with the requirements of this AD: Where EASA AD 2018-0243 refers to its effective date, this AD requires using the effective date of this AD.
(2) The ``Remarks'' section of EASA AD 2018-0243 does not apply to this AD.

(i) 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.

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 the European Aviation Safety Agency (EASA); or Airbus SAS's EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature.
(3) Required for Compliance (RC): For any service information referenced in EASA AD 2018-0243 that contains RC procedures and tests: Except as required by paragraph (i)(2) of this AD, RC procedures and tests must be done to comply with this AD; any procedures or tests that are not identified as RC are recommended. Those procedures and tests that are not identified as RC may be deviated from using accepted methods in accordance with the operator's maintenance or inspection program withoutobtaining approval of an AMOC, provided the procedures and tests identified as RC can be done and the airplane can be put back in an airworthy condition. Any substitutions or changes to procedures or tests identified as RC require approval of an AMOC.

Discussion

The EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2018-0243, dated November 8, 2018 (``EASA AD 2018-0243'') (also referred to after this as the Mandatory Continuing Airworthiness Information,

[[Page 54000]]

or ``the MCAI''), to correct an unsafe condition for all Airbus SAS Model A350-941 and -1041 airplanes.
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 by adding an AD that would apply to all Airbus SAS Model A350-941 and -1041 airplanes. The NPRM published in the Federal Register on June 5, 2019 (84 FR 26023). The NPRM was prompted by reports of disconnections of certain hinge arms of the bulk cargo door (BCD) due to disbonding of the hinge arm bushes. The NPRM proposed to require either modifying and re-identifying affected BCDs or replacing affected BCDs.
The FAA is issuing this AD to address disconnected hinge arms, which, in a case ofditching, could result in the BCD opening inward and allowing water into the cargo hold, and consequent reduced flotation time. See the MCAI for additional background information.

Comments

The FAA gave the public the opportunity to participate in developing this final rule. The FAA has considered the comment received. Air Line Pilots Association, International (ALPA) indicated its support for the NPRM.

Conclusion

The FAA reviewed the relevant data, considered the comment received, and determined that air safety and the public interest require adopting this final rule as proposed, except for minor editorial changes. The FAA has determined that these minor changes:
Are consistent with the intent that was proposed in the NPRM for addressing the unsafe condition; and
Do not add any additional burden upon the public than was already proposed in the NPRM.

Related IBR Material Under 1 CFR Part 51

EASA AD 2018-0243 describes procedures for modifying andreplacing any affected BCD. EASA AD 2018-0243 also describes procedures for re- identifying and installing a standard identification plate on any modified BCD. This material is reasonably available because the interested parties have access to it through their normal course of business or by the means identified in the ADDRESSES section.

Costs of Compliance

The FAA estimates that this AD affects 11 airplanes of U.S. registry. The FAA estimates the following costs to comply with this AD:

Estimated Costs for Required Actions ----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Labor cost Parts cost product operators ---------------------------------------------------------------------------------------------------------------- 9 work-hours x $85 per hour = $765........................... (*) * $765 * $8,415 ----------------------------------------------------------------------------------------------------------------
* The FAA has received no definitive data on the parts costs for required actions

According to the manufacturer, some or all of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage for affected individuals. As a result, the FAA has included all known costs in our cost estimate.

Authority for This Rulemaking

Title 49 of the United States Code specifies the FAA's authority to issue rules on aviation safety. Subtitle I, section 106, describes the authority of the FAA Administrator. Subtitle VII: Aviation Programs, describes in more detail the scope of the Agency's authority.
The FAA is issuing this rulemaking under the authority described in Subtitle VII, Part A, Subpart III, Section 44701: ``General requirements.'' Under that section, Congress chargesthe FAA with promoting safe flight of civil aircraft in air commerce by prescribing regulations for practices, methods, and procedures the Administrator finds necessary for safety in air commerce. This regulation is within the scope of that authority because it addresses an unsafe condition that is likely to exist or develop on products identified in this rulemaking action.
This AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes and associated appliances to the Director of the System Oversight Division.

Regulatory Findings

This AD will not have federalism implications under Executive Order 13132. This AD will not have a substantial direct effect on the States, on the relationship between the national government and the States, or on the distribution of power and responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:
(1) Is not a ``significant regulatory action'' under Executive Order 12866,
(2) Will not affect intrastate aviation in Alaska, and
(3) Will not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act.
