Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is superseding Airworthiness Directive (AD) 2022-03-
12, which applied to all Airbus SAS Model A330-200, -300, -800, and -
900 series airplanes; and Model A340-200, -300, -500, and -600 series 
airplanes. AD 2022-03-12 required replacing the doghouse door lock 
placard with an improved instruction placard. This AD was prompted by 
reports that the instructions on the doghouse door lock placard are 
unclear and incomplete, and by a determination that additional parts 
need to be modified. This AD continues to require the actions in AD 
2022-03-12 and expands the list of affected parts, as specified in a 
European Union Aviation Safety Agency (EASA) AD, which is incorporated 
by reference. This AD also prohibits the installation of affected parts 
under certain conditions. The FAA is issuing this AD to address the 
unsafe condition on these products.

DATES: This AD is effective May 30, 2023.
    The Director of the Federal Register approved the incorporation by 
reference

SUPPLEMENTARY INFORMATION: 

Background

    The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 
CFR part 39 to supersede AD 2022-03-12, Amendment 39-21929 (87 FR 8169, 
February 14, 2022) (AD 2022-03-12). AD 2022-03-12 applied to all Airbus 
SAS Model A330-200, -300, -800, and -900 series airplanes; and Model 
A340-200, -300, -500, and -600 series. AD 2022-03-12 required replacing 
the doghouse door lock placard with an improved instruction placard. AD 
2022-03-12 also prohibited the installation of affected parts under 
certain conditions. The FAA issued AD 2022-03-12 to address possible 
incorrect operation of the doghouse door lock due to unclear and 
incomplete handling instructions on the door placard installed near the 
lock. This condition, if not addressed, could lead to failure of the 
latch, which could block the door in the closed position and prevent 
access to the emergency equipment inside the doghouse.
    The NPRM published in the Federal Register on January 30, 2023 (88 
FR 5814). The NPRM was prompted by AD 2022-0179, dated August 26, 2022, 
issued by EASA, which is the Technical Agent for the Member States of 
the European Union (EASA AD 2022-0179) (also referred to as the MCAI). 
The MCAI states that the instructions on the doghouse door lock placard 
are unclear and incomplete, and could lead to incorrect operation of 
the lock. This condition, if not corrected, could lead to failure of 
the latch, blocking the door in the closed position and preventing 
access to emergency equipment, possibly resulting in injury to airplane 
occupants. Since EASA AD 2021-0136 was issued, it has been determined 
that additional parts need to be modified.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2023-0028.
    In the NPRM, the FAA proposed to continue to require the actions in 
AD 2022-03-12 and expand the list of affected parts, as specified in 
EASA AD 2022-0179, dated August 26, 2022. The NPRM also proposed to 
prohibit the installation of affected parts under certain conditions. 
The FAA is issuing this AD to address possible incorrect operation of 
the doghouse door lock due to unclear and incomplete handling 
instructions on the door placard installed near the lock. The unsafe 
condition, if not addressed, could result in failure of the latch, 
which could block the door in the closed position and prevent access to 
the emergency equipment inside the doghouse.

Discussion of Final Airworthiness Directive

Comments

    The FAA received no comments on the NPRM or on the determination of 
the cost to the public.

Conclusion

    This product has been approved by the aviation authority of another 
country and is approved for operation in the United States. Pursuant to 
the FAA's bilateral agreement with this State of Design Authority, it 
has notified the FAA of the unsafe condition described in the MCAI 
referenced above. The FAA reviewed the relevant data and determined 
that air safety requires adopting this AD as proposed. Accordingly, the 
FAA is issuing this AD to address the unsafe condition on this product. 
Except for minor editorial changes, this AD is adopted as proposed in 
the NPRM. None of the changes will increase the economic burden on any 
operator.

Related Service Information Under 1 CFR Part 51

    EASA AD 2022-0179 specifies procedures for replacing the doghouse 
door lock placard with an improved instruction placard. EASA AD 2022-
0179 also prohibits the installation of doghouses with incorrect 
instruction placards. 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 62 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
              Labor cost                      Parts cost            Cost per product      Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
2 work-hours x $85 per hour = $170...  Up to $95 per placard..  Up to $265 per placard.  Up to $16,430.*
----------------------------------------------------------------------------------------------------------------
* Assuming one placard per product. The number of placards on an airplane depends on the passenger configuration
  and varies from operator to operator.

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

[[Page 24685]]

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.
