14 CFR Part 39

[Docket No. FAA-2013-0418; Directorate Identifier 2012-NM-200-AD; 
Amendment 39-17668; AD 2013-23-13]

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 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 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 AD requires a check 
of maintenance records to determine if certain repairs were done in 
area 1 of the frame base 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 issuing 
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: This AD becomes effective December 30, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of December 30, 
2013.

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 the specified products. The 
NPRM was published in the Federal Register on May 14, 2013 (78 FR 
28159). The NPRM proposed to correct an unsafe condition for the 
specified products. 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 on the 
Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2013-
0418-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We have considered the comment received.

Request To Correct Typographical Error in SUMMARY Section

    UPS noted there is a typographical error in the SUMMARY section of 
the NPRM (78 FR 28159, May 14, 2013). UPS stated that the third line 
includes the phrase ``frame brace fittings,'' but throughout the rest 
of the document the terminology used is ``frame base fittings.'' UPS 
suggested that for

[[Page 70208]]

consistency throughout the document ``brace'' be changed to ``base.''
    We agree that the word ``brace'' should be changed to ``base'' and 
have changed the SUMMARY section of this final rule accordingly. The 
error only appeared in the SUMMARY section so no additional changes 
were necessary.

Conclusion

    We reviewed the available data, including the comment received, and 
determined that air safety and the public interest require adopting 
this AD as proposed except for minor editorial changes and the 
correction of the typographical error in the SUMMARY section of this 
final rule. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (78 FR 28159, May 14, 2013) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 28159, May 14, 2013).

Costs of Compliance

    We estimate that this AD affects 124 airplanes of U.S. registry.
    We estimate it will take 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 $42,160, or $340 per product.
    In addition, we estimate that any necessary follow-on actions will 
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 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.
