DEPARTMENT OF TRANSPORTATION

Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2019-0977; Product Identifier 2019-NM-166-AD; Amendment 
39-19865; AD 2020-05-15]
RIN 2120-AA64

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 A319-131, -132, and -133 airplanes, Model A320-231, -
232, and -233 airplanes, and Model A321-131, -231, and -232 airplanes. 
This AD was prompted by a report of rupture of a hydraulic reservoir 
air pressurization hose on an in-service airplane, leading to air 
leakage that was undetectable during normal operation, and found during 
subsequent zonal inspection. This AD requires modifying the airplane by 
replacing the affected bleed air hoses with a modification of hydraulic 
pressurization lines, 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 April 24, 2020.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of April 24, 
2020.

SUPPLEMENTARY INFORMATION: 

Discussion

    The EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2019-0232, dated September 16, 2019 
(``EASA AD 2019-0232'') (also referred to as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for all Airbus SAS Model A319-131, -132, and -133 airplanes, 
Model A320-231, -232, and -233 airplanes, and Model A321-131, -231, and 
-232 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 
A319-131, -132, and -133 airplanes, Model A320-231, -232, and -233 
airplanes, and Model A321-131, -231, and -232 airplanes. The NPRM 
published in the Federal Register on December 16, 2019 (84 FR 68368). 
The NPRM was prompted by a report of rupture of a hydraulic reservoir 
air pressurization hose on an in-service airplane, leading to air 
leakage that was undetectable during normal operation, and found during 
subsequent zonal inspection. The NPRM proposed to require modifying the 
airplane by replacing the affected bleed air hoses with a modification 
of hydraulic pressurization lines, as specified in an EASA AD.
    The FAA is issuing this AD to address this condition, which, if not 
detected and corrected, could lead to exposure of the wing structure to 
high temperatures (possibly above 200 degrees Celsius (392 degrees 
Fahrenheit)), possibly resulting in reduced structural integrity 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 FAA has considered the comments 
received. The Air Line Pilots Association, International (ALPA) and 
United Airlines indicated support for the NPRM.

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 as proposed, except for minor 
editorial changes. The FAA has 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 IBR Material Under 1 CFR Part 51

    EASA AD 2019-0232 describes procedures for modifying the airplane 
by replacing the affected bleed air hoses with a modification kit that 
includes improved bleed air hoses. 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 802 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

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.
