Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Airbus SAS Model A350-941 airplanes. This AD was prompted by 
the results of a structural analysis, which identified that the upper 
frame fittings (UFFs) of the forward cargo door surrounding structure 
have a low fatigue life. This AD requires repetitive inspections of the 
forward cargo door UFFs and brackets for discrepancies and, depending 
on the findings, doing applicable corrective actions, as specified in a 
European Union Aviation Safety Agency (EASA) AD, which is incorporated 
by reference. The FAA is issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective December 31, 2019.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 31, 
2019.

SUPPLEMENTARY INFORMATION: 

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0126, dated June 5, 2019 
(``EASA AD 2019-0126'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Airbus SAS Model A350-941 airplanes.
    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 by adding an AD that would apply to certain Airbus SAS 
Model A350-941 airplanes. The NPRM published in the Federal Register on 
August 30, 2019 (84 FR 45694). The NPRM was prompted by the results of 
a structural analysis, which identified

[[Page 64988]]

that the UFFs of the forward cargo door surrounding structure have a 
low fatigue life. The NPRM proposed to require repetitive inspections 
of the forward cargo door UFFs and brackets for discrepancies and, 
depending on the findings, doing applicable corrective actions.
    The FAA is issuing this AD to address low fatigue life of the UFFs 
of the forward cargo door surrounding structure, which could lead to 
failure of a forward fuselage cargo door UFF, resulting in reduced 
structural integrity of the fuselage. See the MCAI for additional 
background information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. We have considered the comments received. 
Kate Johnson and an anonymous commenter indicated support for the NPRM.

Conclusion

    The FAA reviewed the relevant data, considered the comments 
received, and determined that air safety and the public interest 
require adopting this final rule as proposed, except for minor 
editorial changes. We have determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM for addressing the unsafe condition; and
    <bullet> 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 2019-0126 describes procedures for repetitive detailed 
inspections of the UFFs and brackets of the forward cargo door for 
discrepancies, including cracking, and applicable corrective actions. 
Corrective actions include a modification to reinforce the affected UFF 
brackets, and repair of any discrepancy detected in the area 
surrounding the UFF brackets. 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 13 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
----------------------------------------------------------------------------------------------------------------
40 work-hours x $85 per hour = $3,400........................              $0           $3,400          $44,200
----------------------------------------------------------------------------------------------------------------

    The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any 
required or optional actions. The FAA has no way of determining the 
number of aircraft that might need these on-condition actions:

                                    Estimated Costs of On-Condition Actions *
----------------------------------------------------------------------------------------------------------------
               Labor cost                             Parts cost                       Cost per  product
----------------------------------------------------------------------------------------------------------------
Up to 132 work-hours x $85 per hour = Up  Up to $6,940......................  Up to $18,160.
 to $11,220.
----------------------------------------------------------------------------------------------------------------
* The FAA has received no definitive data that would enable the agency to provide cost estimates for the on-
  condition repair specified in this AD.

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 charges the 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.
