Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Airbus Model A318, A319, A320, and A321 series airplanes. This AD was 
prompted by reports of cracking of the aft fixed fairing (AFF) of the 
pylons due to fatigue damage of the structure. This AD requires 
repetitive inspections for damage and cracking of the AFF of the 
pylons, and repair if necessary. We are issuing this AD to detect and 
correct damage and cracking of the AFF of the pylons, which could 
result in detachment of a pylon and consequent reduced structural 
integrity of the airplane.

DATES: This AD becomes effective May 10, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 10, 
2016.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 by adding an AD that would apply to certain Airbus Model A318, 
A319, A320, and A321 series airplanes. The NPRM published in the 
Federal Register on November 30, 2015 (80 FR 74729) (``the NPRM'').
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0154, dated July 2, 2014 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A318, A319, A320, and A321 series airplanes. The MCAI states:

    On aeroplanes equipped with post-mod 33844 CFM pylons, several 
operators have reported cracks on the Aft Fixed Fairing (AFF). After 
material analysis, it appears that

[[Page 19483]]

the pylon AFF structure, especially on this configuration, is 
subject to fatigue constraint damage which could lead to pylon AFF 
cracks.
    Further to these findings, Airbus released Alert Operators 
Transmission (AOT) A54N002-12 which provides instructions to inspect 
the pylon AFF, applicable only to aeroplanes incorporating Airbus 
production mod 33844 on CFM pylons. More recently, Airbus issued 
Service Bulletin (SB) A320-54-1027, superseding AOT A54N002-12.
    This condition, if not detected and corrected, could lead to 
detachment of a pylon AFF from the aeroplane, possibly resulting in 
injuries to persons on the ground.
    For the reasons described above, this [EASA] AD requires 
repetitive detailed inspections (DET) of the pylon AFF and, 
depending on findings, accomplishment of applicable corrective 
action(s).

    Since the MCAI was issued, EASA has clarified that the detachment 
of a pylon AFF from the airplane could result in damage to the 
airplane; such damage could result in reduced structural integrity of 
the airplane.
    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2015-
6537.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public.

Explanation of Change to the Proposed Applicability

    We have removed Airbus Model A320-215 airplanes from the 
Applicability statement of this AD; this model is not type certificated 
in the U.S.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting this AD with the change described 
previously, including minor editorial changes. We have determined that 
these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A320-54-1027, dated April 10, 
2014. This service information describes procedures for inspections for 
damage and cracking of the AFF of the pylons, and repair if necessary. 
This service information 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

    We estimate that this AD affects 69 airplanes of U.S. registry.
    We also estimate that it takes about 4 work-hours per product to 
comply with the basic requirements of this AD. The average labor rate 
is $85 per work-hour. Based on these figures, we estimate the cost of 
this AD on U.S. operators to be $23,460, or $340 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in 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.
    We are 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

    We determined that 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. Is not a ``significant rule'' under the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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.
