Airworthiness Directives; Airbus SAS Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus SAS Model A350-941 airplanes. This AD was prompted by an 
inspection on the production line that revealed evidence of paint 
peeling on the forward and aft cargo frame forks around the hook bolt 
hole. This AD requires a detailed visual inspection for any deficiency 
of the frame forks around the hook bolt hole on certain forward and aft 
cargo doors and applicable corrective actions. We are issuing this AD 
to address the unsafe condition on these products.

DATES: This AD is effective November 15, 2018.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of November 15, 
2018.

SUPPLEMENTARY INFORMATION: 

Discussion

    We 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 airplanes. The NPRM published in the Federal Register on May 15, 
2018 (83 FR 22414). The NPRM was prompted by an inspection on the 
production line that revealed evidence of paint peeling on the forward 
and aft cargo frame forks around the hook bolt hole. The NPRM proposed 
to require a detailed visual inspection for any deficiency of the frame 
forks around the hook bolt hole on certain forward and aft cargo doors 
and applicable corrective actions.
    We are issuing this AD to address paint peeling on the forward and 
aft cargo doors that could develop into galvanic corrosion, which could 
lead to cargo door failure and possibly result in decompression of the 
airplane and injury to occupants.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA AD 
2018-0031, dated January 31, 2018 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for all Airbus SAS Model A350-941 
airplanes. The MCAI states:

    Following an inspection on the production line, paint peeling 
was found on forward and aft cargo door frame forks around the hook 
bolt hole. Subsequent investigations determined this had been caused 
by incorrect masking method during application of primer, top coat 
and Tartaric Sulfuric Anodizing (TSA) layer. As the cargo doors are 
located in an area with high corrosion sensitivity, where a surface 
protection with primer, top coat and TSA is specified, in case of 
paint peeling off, galvanic corrosion could develop.
    This condition, if not detected and corrected, could lead to 
cargo door failure, possibly resulting in decompression of the 
aeroplane and injury to occupants.
    To address this potential unsafe condition, Airbus identified 
the affected parts and issued the SB [Airbus Service Bulletin (SB) 
A350-52-P011, dated May 12, 2017] to provide inspection 
instructions.
    For the reasons described above, this [EASA] AD requires a one-
time detailed [visual] inspection (DET) of the affected parts [for 
discrepancies] and, depending on findings, accomplishment of 
applicable corrective action(s) [i.e., restoration of the anti-
corrosion protection of frame forks of affected parts].

    You may examine the MCAI in the AD docket on the internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2018-
0410.

Comments

    We gave the public the opportunity to participate in developing 
this final rule. We received no comments on the NPRM or on the 
determination of the cost to the public.

Clarification of Definition of Serviceable Part

    We have changed paragraph (g)(2) in this AD by adding that a 
serviceable part is also ``a part identified as an affected part, and 
the actions in paragraph (i) of this AD have been accomplished on that 
part.'' This change has been coordinated with EASA and Airbus.

Conclusion

    We reviewed the relevant data 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:
     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 Service Information Under 1 CFR Part 51

    Airbus SAS has issued Airbus Service Bulletin A350-52-P011, dated 
May 12, 2017. This service information describes procedures for a one-
time detailed visual inspection of the frame forks around the hook bolt 
hole on the forward and aft cargo door, and applicable corrective 
actions. This service information is reasonably

[[Page 51314]]

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

    We estimate that this AD affects 9 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
             Action                  Labor cost        Parts cost     Cost per product    Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Inspection.....................  Up to 9 work-hours              $0  Up to $765........  Up to $6,885.
                                  x $85 per hour =
                                  $765.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary on-condition 
actions that would be required based on the results of the inspection. 
We have no way of determining the number of aircraft that might need 
this action:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per
                    Action                                 Labor cost               Parts cost        product
----------------------------------------------------------------------------------------------------------------
Restoration...................................  9 work-hours x $85 per hour =                $50           $815.
                                                 $765.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, all of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all 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.
    We are 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) Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979),
    (3) Will not affect intrastate aviation in Alaska, and
    (4) 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.
