Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for all 
Airbus Model A318-111 and -112 airplanes; Model A319-111, -112, and -
115 airplanes; Model A320-214 airplanes; and Model A321-111, -112, -
211, -212, and -213 airplanes. This proposed AD was prompted by reports 
of cracked cadmium-plated lock nuts that attach the hinge to the fan 
cowl door. This proposed AD would require inspecting to determine the 
serial number of each engine fan cowl door, inspecting for cracking of 
the hinge lock nuts of any affected door, and replacing the lock nuts 
if necessary. We are proposing this AD to detect and correct cracking 
of the hinge lock nuts, which could result in separation of the hinge 
from the fan cowl door, in-flight loss of the door, and consequent 
damage to the airplane.

DATES: We must receive comments on this proposed AD by August 17, 2015.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Union, has issued EASA 
Airworthiness Directive 2014-0276, dated December 19, 2014 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus Model 
A318-111 and -112 airplanes; Model A319-111, -112, and -115 airplanes; 
Model A320-214 airplanes; and Model A321-111, -112, -211, -212, and -
213 airplanes. The MCAI states:

    In-service findings have been reported of cracked cadmium plated 
lock nuts. This cracking occurs shortly after installation. 
Investigation results attribute the cause to an improper 
manufacturing procedure of the nuts. It was determined that the 
affected batch of lock nuts was used on the fan cowl to attach 
hinges to the cowl doors on CFM56-5B engines only.
    This condition, if not corrected, could lead to separation of 
the hinge from the fan cowl door, possibly resulting in in-flight 
loss of a fan cowl door, with consequent damage to the aeroplane 
and/or injury to persons on the ground.
    For the reasons describes above, this [EASA] AD required 
identification of the affected fan cowl doors, a one-time inspection 
of the fan cowl door hinge nuts and, depending on findings, 
replacement of the affected nuts.

    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-
1991.

Related Service Information Under 1 CFR Part 51

    Airbus has issued Service Bulletin A320-71-1062, including Appendix 
01, dated July 28, 2014. Goodrich Aerostructures has issued Service 
Bulletin RA32071-151, dated June 11, 2014. The service information 
describes procedures for inspection of the hinge nuts of the fan cowl 
door, and replacement 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 of this NPRM.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation

[[Page 38037]]

in the United States. Pursuant to our bilateral agreement with the 
State of Design Authority, we have been notified of the unsafe 
condition described in the MCAI and service information referenced 
above. We are proposing this AD because we evaluated all pertinent 
information and determined an unsafe condition exists and is likely to 
exist or develop on other products of these same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 437 airplanes of U.S. 
registry.
    We also estimate that it would take about 2 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Required parts would cost about $0 per 
product. Based on these figures, we estimate the cost of this proposed 
AD on U.S. operators to be $74,290, or $170 per product.
    We have received no definitive data that would enable us to provide 
a cost estimate for the on-condition actions specified in this proposed 
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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    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.
