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 A300 B4-603, B4-620, and B4-622 airplanes; Model A300 B4-
605R and A300 B4-622R airplanes; and Model A300 C4-605R Variant F 
airplanes. This proposed AD was prompted by an in-service detection of 
cracks in the fuselage skin lap joints. This proposed AD would require 
an ultrasonic inspection of certain skin lap joints, and repair if 
necessary. We are proposing this AD to detect and correct cracks in 
certain skin lap joints. Such cracking could result in reduced 
structural integrity of the airplane.

DATES: We must receive comments on this proposed AD by October 14, 
2016.

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 2016-0557, dated March 18, 2016 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for all Airbus Model A300 
B4-603, B4-620, and B4-622 airplanes; Model A300 B4-605R and A300 B4-
622R airplanes; and Model A300 C4-605R Variant F airplanes. The MCAI 
states:

    Prompted by in-service detection on Airbus A300-600 aeroplanes 
of cracks in certain fuselage skin lap joints, several studies were 
launched to understand the phenomenon and provide the corrective 
actions. More recently, new analyses were performed and the results 
identified that a new area has to be inspected at the skin lap joint 
below Stringer (STR) 28 at Frame (FR) 72 to FR 76.
    This condition, if not detected and corrected, could result in 
reduced structure integrity of the aeroplane.
    To address this unsafe condition, Airbus published Service 
Bulletin (SB) A300-53-6184 [dated November 12, 2015] to introduce 
inspections and applicable corrective actions for the affected 
areas.
    For the reason described above, this [EASA] AD requires 
repetitive Special Detail Inspections (SDI) of the affected skin lap 
joint and, depending on findings, accomplishment of applicable 
corrective action(s) [repairs].

    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-2016-
9051.

Related Service Information Under 1 CFR Part 51

    We reviewed Airbus Service Bulletin A300-53-6184, November 12, 
2015. The service information describes procedures for an ultrasonic 
inspection of the skin lap joint below stringer 28 at FR 72 to FR 76, 
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.

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 these 
same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 29 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                Action                        Labor cost            Cost per product      Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Ultrasonic inspection................  6 work-hours x $85 per   $510 per inspection      $14,790 per inspection
                                        hour = $510 per          cycle.                   cycle.
                                        inspection cycle.
----------------------------------------------------------------------------------------------------------------

    We have no way to determine the costs to do any necessary repairs 
that would be required based on the results of the proposed inspection. 
We have no way of determining the number of airplanes that might need 
these repairs.

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,

[[Page 59532]]

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.
