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 B4-103, B4-203, and B4-2C airplanes, and Model A300 
B4-600, B4-600R, and F4-600R series airplanes, and Model A300 C4-605R 
Variant F airplanes (collectively called A300-600 series airplanes). 
This AD was prompted by reports of cracking in the forward lug of the 
main landing gear (MLG) rib 5 aft bearing attachment. This AD requires 
repetitive inspections for cracking of the left-hand (LH) and right-
hand (RH) wing MLG rib 5 aft bearing forward lugs, and repair if 
necessary. We are issuing this AD to detect and correct cracking of the 
LH and RH wing MLG rib 5 aft bearing forward lugs, which could affect 
the structural integrity of the MLG attachment, resulting in MLG 
collapse during landing or rollout with consequent damage to the 
airplane and injury to occupants.

DATES: This AD becomes effective September 11, 2012.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of September 11, 
2012.

ADDRESSES: You may examine the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> or in person at the U.S. Department of 
Transportation, Docket Operations, M-30, West Building Ground Floor, 
Room W12-140, 1200 New Jersey Avenue SE., Washington, DC.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on February 28, 2012 
(77 FR 11793). That NPRM proposed to correct an unsafe condition for 
the specified products. The MCAI states:

    During routine visual inspection, a crack has been found in the 
wing MLG [main landing gear] rib 5 aft bearing forward lug on two 
A310 in-service aeroplanes. Laboratory examination of cracked ribs 
confirmed that the crack was due to the presence of pitting 
corrosion in the forward lug hole. Also on both aeroplanes medium to 
heavy corrosion was found in the forward lugs on the opposite wing 
after removal of the bushes. Similarly to A310 aeroplanes, A300 and 
A300-600 aeroplanes are concerned by this situation which, if not 
detected, could affect the structural integrity of the MLG 
attachment.
    The aim of the [EASA] Emergency Airworthiness Directive (EAD) 
2006-0372-E [which corresponds to FAA AD 2007-03-18, Amendment 39-
14929 (72 FR 5919, February 8, 2007)] was to mandate, for A300 and 
A300-600 aeroplanes, repetitive detailed visual inspections (DVI) of 
wing MLG rib 5 aft bearing forward lugs for detection of through 
cracks.
    Since then, in order to ensure the detection of any crack in the 
forward lug of the RH [right-hand] and LH [left-hand] MLG rib 5 aft 
bearing attachment at an early stage, Airbus has developed a new 
inspection by means of ultrasonic method. Due to the early crack 
detection possibility, this new means of inspection also enables 
extension of the inspection interval.
    For technical reasons, this new means of inspection is only 
applicable to A300B4, C4,

[[Page 46938]]

and F4 and A300-600 aeroplane series (not to A300B2 aeroplane 
series).
    For these reasons, this new [EASA] AD * * * adds new inspection 
program requirements [a revised detailed inspection, optional 
ultrasonic inspections, and repair if necessary].

As an option, a modification, which includes installing bushings with 
an increased interference fit in the aft bearing forward lugs, 
terminates the repetitive inspections. You may obtain further 
information by examining the MCAI in the AD docket.

Comments

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

Request To Refer to Revised Service Bulletin

    UPS requested that we revise the NPRM (77 FR 11793, February 28, 
2012) to refer to Airbus Mandatory Service Bulletin A300-57-6106, 
Revision 03, dated January 26, 2012. UPS pointed out that this revised 
service bulletin provides a new repair drawing that supersedes a 
previous repair drawing.
    We agree. We have changed paragraphs (j) and (o) of this AD to 
refer to Airbus Mandatory Service Bulletin A300-57-6106, Revision 03, 
dated January 26, 2012. We have also added paragraph (m)(5) to this AD 
to give credit for actions done before the effective date of this AD 
using Airbus Service Bulletin A300-57-6106, Revision 02, dated June 18, 
2010.

Request To Change Paragraph Reference for Terminating Action

    UPS stated that paragraph (k) of the NPRM (77 FR 11793, February 
28, 2012) provides terminating action to AD 2007-03-18, Amendment 39-
14929 (72 FR 5919, February 8, 2007), by doing the inspections called 
out in paragraph (g) of the NPRM. UPS stated that the reference for the 
terminating action for the repetitive inspections of this NPRM and for 
AD 2007-03-18 should be paragraph (j) of the NPRM.
    We agree that paragraph (k) of this AD should refer to paragraph 
(j), not paragraph (g), of this AD for the terminating modification. 
Paragraph (k) of this AD has been changed to refer to paragraph (j) of 
this AD.

Request To Specify Terminating Action for Related AD

    UPS requested that we refer to Airbus Mandatory Service Bulletin 
A300-57-6106, Revision 03, dated January 26, 2012, which clarifies that 
the terminating action for the repetitive inspections includes 
replacing the bushings. UPS also requested that the same reference be 
included in a related NPRM (Docket No. FAA-2011-1225, Directorate 
Identifier 2010-NM-269-AD).
    We agree that the terminating action should include replacing the 
bushings, which is clarified in Airbus Mandatory Service Bulletin A300-
57-6106, Revision 03, dated January 26, 2012. As stated previously, we 
have changed paragraph (j) of this AD to refer to Airbus Mandatory 
Service Bulletin A300-57-6106, Revision 03, dated January 26, 2012. No 
further change to this AD is necessary.
    Directorate Identifier 2010-NM-269-AD, has been issued as AD 2012-
08-03, Amendment 39-17019 (77 FR 24367, April 24, 2012), and refers to 
Airbus Mandatory Service Bulletin A300-57-6106, Revision 03, dated 
January 26, 2012, for the terminating action.

Other Change Made To This AD

    We have revised paragraph (m) of this AD to refer to paragraph (j) 
of this AD instead of paragraph (g) of this AD.

Conclusion

    We reviewed the available data, including the comments received, 
and determined that air safety and the public interest require adopting 
the AD with the changes described previously and minor editorial 
changes. We have determined that these changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM (77 FR 11793, February 28, 2012) for correcting the unsafe 
condition; and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 11793, February 28, 2012).

Costs of Compliance

    We estimate that this AD will affect 165 products of U.S. registry. 
We also estimate that it will take about 3 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 to the U.S. operators to be $42,075, or $255 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 52 work-hours and require parts costing $4,590, for a cost 
of $9,010 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.

Examining the AD Docket

    You may examine the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a>; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains the NPRM (77 FR 11793, February 28, 
2012), the regulatory evaluation, any comments received, and other 
information. The street address for the Docket Operations office 
(telephone (800) 647-5527) is in the ADDRESSES section. Comments will 
be available in the AD docket shortly after receipt.
