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 all 
Airbus SAS Model A300 B2K-3C, B2-203, B4-2C, and B4-203 airplanes. This 
AD was prompted by a determination that internal system pollution can 
occur, most likely due to corroded unions in the pressurization lines, 
with an associated risk of contamination of the check valves. This AD 
requires repetitive inspections (functional checks) of the 
pressurization of the hydraulic system reservoirs, and corrective 
actions if necessary, 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 March 14, 2023.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of March 14, 
2023.

ADDRESSES: 
    AD Docket: You may examine the AD docket at regulations.gov under 
Docket No. FAA-2022-1412; or in person at Docket Operations between 9

SUPPLEMENTARY INFORMATION: 

Background

    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 
A300 B2-203, A300 B2K-3C, A300 B4-203, and A300 B4-2C airplanes. The 
NPRM published in the Federal Register on November 18, 2022 (87 FR 
69222).
    The NPRM was prompted by AD 2022-0116, dated June 21, 2022, issued 
by EASA, which is the Technical Agent for the Member States of the 
European Union (EASA AD 2022-0116) (also referred to as the MCAI). The 
MCAI states that internal system pollution can occur, most likely due 
to corroded unions at the pressurization lines, with an associated risk 
of contamination of the check valves. The three hydraulic system 
reservoirs are pressurized by air coming from the engine or the 
auxiliary power unit bleed air duct or from the ground connection. Air 
tightness of the pressurization system of the reservoirs is achieved by 
check valves that are located on the respective pressurization lines 
and on top of each hydraulic reservoir.
    In the NPRM, the FAA proposed to require repetitive inspections 
(functional checks) of the pressurization of the hydraulic system 
reservoirs, and corrective actions if necessary, as specified in EASA 
AD 2022-0116. The FAA is issuing this AD to address check valve 
contamination, which could lead to hydraulic reservoir pressurization 
issues and, if combined with an air pressurization line rupture, could 
lead to loss of hydraulic systems and possibly result in loss of 
control of the airplane. See the MCAI for additional background 
information.
    You may examine the MCAI in the AD docket at regulations.gov under 
Docket No. FAA-2022-1412.

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 2022-0116 specifies procedures for repetitive detailed 
inspections by performing functional checks for air leakage of the 
hydraulic system reservoirs and corrective actions. Corrective actions 
include a fault isolation to identify the source of depressurization 
and replacement of the check valves. EASA AD 2022-0116 also specifies 
procedures for reporting the inspection findings.
    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 2 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with 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 a 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 currently valid OMB Control Number. The OMB 
Control Number for this information collection is 2120-0056. Public 
reporting for this collection of information is estimated to take 
approximately 1 hour per response, including the time for reviewing 
instructions, searching existing data sources, gathering and 
maintaining the data needed, and completing and reviewing the 
collection of information. All responses to this collection of 
information are mandatory. Send comments regarding this burden estimate 
or any other aspect of this collection of information, including 
suggestions for reducing this burden, 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.
