14 CFR Part 39

[Docket No. FAA-2022-0522; Project Identifier MCAI-2022-00340-T; 
Amendment 39-22135; AD 2022-16-06]
RIN 2120-AA64

Airworthiness Directives; Airbus SAS Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Airbus SAS Model A330-200, A330-200 Freighter, A330-300, and 
A330-900 series airplanes; and all Model A340-200 and A340-300 series 
airplanes. This AD was prompted by recent tests that demonstrated that 
when the upper secondary load path (SLP) of the trimmable horizontal 
stabilizer actuator (THSA) is engaged, the THSA might not stall, with 
consequently no indication of SLP engagement. This AD requires 
modifying the THSA installation, implementing the electrical load 
sensing device (ELSD) wiring provisions, and installing and activating 
the ELSD, 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 September 27, 2022.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of September 
27, 2022.

SUPPLEMENTARY INFORMATION:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2022-0039, dated March 8, 2022 (EASA 
AD 2022-0039) (also referred to as the MCAI), to correct an unsafe 
condition for certain Airbus SAS Model A330-201, A330-202, A330-203, 
A330-223, A330-223F, A330-243, A330-243F, A330-301, A330-302, A330-303, 
A330-321, A330-322, A330-323, A330-341, A330-342, A330-343, and A330-
941 airplanes; and all Model A340-211, A340-212, A340-213, A340-311, 
A340-312, and A340-313 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 A330-201, A330-202, A330-203, A330-223, A330-223F, A330-243, 
A330-243F, A330-301, A330-302, A330-303, A330-321, A330-322, A330-323, 
A330-341, A330-342, A330-343, and A330-941 airplanes; and all Model 
A340-211, A340-212, A340-213, A340-311, A340-312, and A340-313 
airplanes. The NPRM published in the Federal Register on May 19, 2022 
(87 FR 30434). The NPRM was prompted by recent tests that demonstrated 
that when the upper SLP of the THSA is engaged, the THSA might not 
stall, with consequently no indication of SLP engagement. The NPRM 
proposed to require modifying the THSA installation, implementing the 
ELSD wiring provisions, and installing and activating the ELSD, as 
specified in EASA AD 2022-0039.
    The FAA is issuing this AD to address the unsafe condition on these 
products. See the MCAI for additional background information.

Discussion of Final Airworthiness Directive

Comments

    The FAA received comments from the Air Line Pilots Association, 
International, which supported the NPRM without change.

Conclusion

    The FAA reviewed the relevant data, considered the comments 
received, and determined that air safety requires adopting this AD as 
proposed. 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. Accordingly, the FAA is issuing this AD to 
address the unsafe condition on these products.

Related Service Information Under 1 CFR Part 51

    EASA AD 2022-0039 specifies procedures for modification to the THSA 
by installation and activation of the ELSD, and installation of the 
wiring provisions for the ELSD. The installation and activation of the 
ELSD include installation of the ELSD on the THSA, modification of the 
electrical harness, and modification of the circuit breaker in the 
auxiliary power unit (APU) control box. The installation of the wiring 
provisions for the ELSD includes modifying the structure at frame 87, 
installing the brackets at frame 87, installing the electrical dummy 
connectors, rerouting the wire between frame 56 and frame 69, modifying 
the circuit breaker box, modifying the electrical harness, and 
rerouting the wiring.

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

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.
