RIN 2120-AA64

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 
certain Airbus Model A320-212, -214, -232, and -233 airplanes. This 
proposed AD was prompted by a report of a crack found during an 
inspection of the pocket radius of the fuselage frame. This proposed AD 
would require repetitive low frequency eddy current inspections or 
repetitive high frequency eddy current inspections of this area, and 
repair if necessary. The repair terminates the repetitive inspections. 
We are proposing this AD to detect and correct any cracking of the 
pocket radius, which could lead to in-flight decompression of the 
airplane and possible injury to the passengers.

DATES: We must receive comments on this proposed AD by October 13, 
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 2014-0278, dated December 19, 2014 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for certain Airbus Model 
A320-212, -214, -232, and -233 airplanes. The MCAI states:

    An operator reported finding a crack during an inspection in 
accordance with the instructions of Airbus Alert Operators 
Transmission (AOT) A53N007-14. What was found, a 170 mm through-
thickness crack in the pocket radius between frame 36 and 37 above 
stringer 6 on left hand (LH) side lap joint, was not the aim of the 
AOT inspection. Prior to this finding, the operator reported noise 
in the affected area during several weeks.
    This condition, if not detected and corrected, could lead to in-
flight decompression of the aeroplane, possibly resulting in injury 
to occupants.
    To address this unsafe condition, Airbus published AOT A53N009-
14 to provide inspection and repair instructions to detect and 
prevent crack propagation.
    EASA decided to agree on a sampling inspection to determine 
whether additional aeroplanes need to be inspected.
    For the reasons described above, this [EASA] AD requires, for 
the selected aeroplanes, repetitive Low Frequency Eddy Current 
(LFEC) or High Frequency Eddy Current (HFEC) inspections of the 
pocket radii [for cracks] located between fuselage frames 35 and 40, 
above stringer 6 on both LH and right hand (RH) sides and, depending 
on findings, accomplishment of repair instructions.
    This [EASA] AD is considered an interim action and further 
[EASA] AD action may follow.

    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-
3148.

Related Service Information Under 1 CFR Part 51

    We reviewed Airbus Alert Operators Transmission A53N009-14, dated 
December 17, 2014. The service information describes procedures for 
repetitive inspections of the pocket radii located between fuselage 
frames 35 and 40, above stringer 6 on both the left- and right-hand 
sides, 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 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 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 the same 
type design.

Costs of Compliance

    We estimate that this proposed AD affects 1 airplane of U.S. 
registry.
    We also estimate that it would take about 3 work-hours per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this proposed AD on U.S. operators to be $255, or $255 per 
product.
    We have received no definitive data that would enable us to provide 
cost estimates 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.
