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 A300 series airplanes; Model A300 B4-600, B4-600R, 
and F4-600R series airplanes, and Model A300 C4-605R Variant F 
airplanes (collectively called Model A300-600 series airplanes). This 
proposed AD was prompted by a report that cracking was found in area 2 
of the frame base fittings between frame 41 and frame 46. This proposed 
AD would require a check of maintenance records to determine if certain 
repairs were done in area 1 of the frame brace fittings, and, for 
affected airplanes, a detailed inspection for cracking in area 2 of the 
frame base fittings between frame 41 and frame 46, and repair if 
necessary. We are proposing this AD to detect and correct cracking in 
area 2 of the frame base fittings between frame 41 and frame 46, which 
could adversely affect the structural integrity of the airplane.

DATES: We must receive comments on this proposed AD by June 28, 2013.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2012-0229, dated October 31, 2012 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    During accomplishment of Airbus SB [service bulletin] A300-53-
6111, which addresses detailed visual inspections of the lower frame 
fittings between Frame (FR) 41 and FR 46, on one A300-600 aeroplane 
a crack was detected in the area 2 of the foot of frame FR 46 at 
junction radius level.
    This frame, that was previously repaired due to a crack finding 
in the area 1, was not due to be inspected before reaching the post-
repair inspection threshold, i.e., 45,400 FC [flight cycles], from 
repair embodiment.
    It has been determined that the current repairs proposed in 
Airbus SB A300-53-6111 and Airbus [SB] A300-53-0337 are of limited 
effect to prevent cracking in the area 2 of the lower frame 
fittings.
    Consequently, as a temporary action and until an improvement of 
the existing repairs is made available, this [EASA] AD requires a 
one-time detailed visual inspection [for cracking] of [the] frame 
base fittings that were repaired in accordance with Airbus SB A300-
53-0337, original issue or Rev. 1, or Airbus SB A300-53-6111 
original issue up to Rev. 4 * * *.

    The unsafe condition is cracking in the frame base fittings, which 
could adversely affect the structural integrity of the airplane. The 
required actions include repairing any cracking found. You may obtain 
further information by examining the MCAI in the AD docket.

Relevant Service Information

    Airbus has issued Alert Operators Transmission (AOT) A53W001-12, 
dated July 4, 2012, including Appendices 1, 2, and 3. The actions 
described in this service information are intended to correct the 
unsafe condition identified in the MCAI.

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.

Differences Between This Proposed AD and the MCAI

    Although EASA AD 2012-0229, dated October 31, 2012, specifies to 
contact the manufacturer for instructions to repair certain conditions, 
this proposed AD would require repairing those conditions using a 
method approved by either the Manager, International Branch, ANM-116, 
Transport Airplane Directorate, FAA; or EASA (or its delegated agent).

Costs of Compliance

    Based on the service information, we estimate that this proposed AD 
would affect about 124 products of U.S. registry. We also estimate that 
it would take about 4 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 the proposed 
AD on U.S. operators to be $42,160, or $340 per product.
    In addition, we estimate that any necessary follow-on actions would 
take up to 350 work-hours and require parts costing up to $56,469 for a 
cost of $86,219 per product. We have no way of determining the number 
of products that may need these actions.

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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.
