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 all 
Airbus SAS Model A350-941 and -1041 airplanes. This AD was prompted by 
reports of passenger door girt bar fitting assembly safety hooks being 
stuck in the upward position. This AD requires repetitive detailed 
inspections of girt bar fitting assemblies, repetitive greasing of girt 
bar fitting assembly bushes, and, depending on findings, accomplishment 
of 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 May 4, 2020.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 4, 2020.

SUPPLEMENTARY INFORMATION:

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0207, dated August 22, 2019 
(``EASA AD 2019-0207'') (also referred to as the Mandatory Continuing 
Airworthiness Information, 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 November 15, 2019 (84 FR 62485). The NPRM was prompted by 
reports of passenger door girt bar fitting assembly safety hooks being 
stuck in the upward position. The NPRM proposed to require repetitive 
detailed inspections of girt bar fitting assemblies, repetitive 
greasing of girt bar fitting assembly bushes, and, depending on 
findings, accomplishment of applicable corrective actions.
    The FAA is issuing this AD to address passenger door girt bar 
fitting assembly safety hooks being stuck in the upward position, which 
could lead to girt bar disengagement from the girt bar fitting assembly 
and consequent failure of the passenger door slide deployment during an 
emergency, possibly preventing safe evacuation of the airplane. See the 
MCAI for additional background information.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The following presents the comments 
received on the NPRM and the FAA's response to each comment.

Support for the NPRM

    The Air Line Pilots Association, International (ALPA) indicated its 
support for the NPRM.

Request To Remove or Revise Reporting Requirement

    Delta Air Lines (Delta) requested that the proposed AD be revised 
to either not require reporting or to require reporting only in the 
case of discrepant findings. Delta noted that only 5 discrepant safety 
hooks were found during its inspection of 1,408 fittings. Delta added 
that the final fix will include a retrofit of the girt bar fittings, 
which should occur regardless of the number of reported failures.
    The FAA disagrees with the commenter's request. Reporting is 
necessary for the girt bar fitting assembly manufacturer to determine 
the extent of the discrepancies and to ascertain any necessary follow-
on actions. The FAA has not changed this AD in this regard.

Request To Revise Reporting Compliance Time

    Delta requested that paragraph (h)(3)(i) of the proposed AD be 
reworded to state that inspection report must be submitted within 90 
days after the end of the maintenance visit/check during which the 
inspection was performed, rather than within 90 days after the 
inspection. Delta noted that maintenance personnel often do not report 
findings to engineering until closure of the maintenance visit/check, 
which usually happens several days or weeks after the inspection was 
actually performed. Delta suggested that the revised reporting time 
would remove restrictive time constraints while still meeting the 
intent of the proposed AD.
    The FAA agrees with the commenter's request for the reasons 
provided. The FAA has revised paragraph (h)(3)(i) of this AD to specify 
that a report of findings must be submitted within 90 days after the 
conclusion of the maintenance visit or check where the inspection was 
completed.

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 with the change described previously 
and minor editorial changes. The FAA has determined that these minor 
changes:

[[Page 17479]]

     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.
    The FAA also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this final 
rule.

Related IBR Material Under 1 CFR Part 51

    EASA AD 2019-0207 describes procedures for repetitive detailed 
inspections of girt bar fitting assemblies, repetitive greasing of girt 
bar fitting assembly bushes, and, depending on findings, accomplishment 
of applicable corrective actions. Corrective actions include rework and 
replacement. EASA AD 2019-0207 also describes procedures for sending 
inspection results to Airbus. 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.

Interim Action

    The FAA considers this AD interim action. If final action is later 
identified, the FAA might consider further rulemaking then.

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
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85.............................              $0              $85           $1,105
----------------------------------------------------------------------------------------------------------------
* Table does not include estimated costs for reporting.

    The FAA estimates that it would take about 1 work-hour per product 
to comply with the reporting requirement in this AD. The average labor 
rate is $85 per hour. Based on these figures, the FAA estimates the 
cost of reporting the inspection results on U.S. operators to be 
$1,105, or $85 per product.
    The FAA estimates the following costs to do any necessary on-
condition actions that would be required based on the results of any 
required 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
------------------------------------------------------------------------
                                                             Cost per
              Labor cost                   Parts cost        product
------------------------------------------------------------------------
Up to 3 work-hours x $85 per hour =              (\*\)         $255 \*\
 $255.................................
------------------------------------------------------------------------
* The FAA has received no definitive data that would enable the agency
  to provide parts cost estimates for the on-condition actions specified
  in this AD.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to 
Information Collection Clearance Officer, Federal Aviation 
Administration, 10101 Hillwood Parkway, Fort Worth, TX 76177-1524.

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.

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.
