SUMMARY: We are adopting a new airworthiness directive (AD) for all
Airbus Model A300 series airplanes; Model A310 series airplanes; and
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 reports of cracked fuel pump
canister hoods located in fuel tanks. This AD requires replacing any
cracked hood halves of fuel pump canisters. We are issuing this AD to
prevent any detached canister hood fragments/debris from being ingested
into the fuel feed system, and becoming a potential source of ignition
with consequent fire or explosion.
DATES: This AD becomes effective November 27, 2012.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of November 27,
2012.

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 22, 2012
(77 FR 10409). That NPRM proposed to correct
[[Page 64702]]
an unsafe condition for the specified products. The MCAI states:
This [European Aviation Safety Agency (EASA)] AD results from
findings of cracked fuel pump canister hoods located in fuel tanks.
From the analyses, laboratory testing and examinations made so
far, it is presently thought that vibration-induced fatigue can be
identified as the root cause for the cracks found on in-service
aeroplanes. However, current data does not yet permit to exclude
some other potential contributing factors.
This condition, if not detected and corrected, could lead to
detached canister hood fragments/debris to be ingested into the fuel
feed system. Also, the metallic debris inside the fuel tank could
result in a potential source of ignition and consequent fire or
explosion.
For the reasons described above, this [EASA] AD requires
repetitive [detailed] inspections of all fuel pump canister hood
halves and their replacement if any [cracking] damage is found. This
[EASA] AD also requires the inspection results to be reported.
This [EASA] AD is considered to be an interim action. The
reports that are required by this [EASA] AD will enable the
manufacturer to obtain better insight into the nature, cause, and
extent of the fuel pump canister hood cracking, and eventually to
develop final action to address the unsafe condition. Once final
action has been identified, further AD actions could be considered.
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 have considered the comments received.
Request To Extend Reporting Time
FedEx requested that the time for submitting reports, proposed in
the NPRM (77 FR 10409, February 22, 2012) as 30 days, be extended to 90
days, because it might not have immediate access to maintenance
vendors' records of the completed tasks, and system-wide reporting can
sometimes require longer times.
Although EASA AD 2011-0124, dated June 30, 2011, specifies a 30-day
compliance time for submitting reports, we agree with the commenter's
request to extend the compliance time for reporting because a delay
will not compromise safety. We have changed paragraphs (j)(1) and
(j)(2) of this final rule accordingly. This difference has been
coordinated with EASA.
Request for Specific Contact Information for Reporting
FedEx requested that we provide specific information for submitting
the reports proposed in the NPRM (77 FR 10409, February 22, 2012),
including an email address, to facilitate reporting.
We agree with the commenter's request for the reason given, and
have added that information in paragraph (j) of this final rule.
Request To Delay the Final Rule Effective Date and Extend the
Compliance Time
UPS requested that the AD be effective after Airbus completes
certifying the improved design for the fuel pump half hood, projected
to be completed in late 2012. UPS also requested an initial compliance
time of 36 months (versus the 30 months proposed in the NPRM (77 FR
10409, February 22, 2012)) to allow for purchasing and part lead time.
UPS stated that these changes to the NPRM would enable a one-time
through-the-fleet solution without the need for repetitive inspections.
We do not agree with the commenter's request for extending the
compliance time. In developing an appropriate compliance time for this
action, we considered not only the degree of urgency associated with
addressing the subject unsafe condition, but the manufacturer's and
EASA's recommendations for an appropriate compliance time, and the
availability of required parts. We have not changed the AD in this
regard.
Further, we do not agree with the request for delaying the AD. For
continued operational safety, operators need to begin the inspections,
and not delay the inspections until the part is certified. We will
consider an alternative method of compliance (AMOC) when parts are
available. Operators may request approval of an AMOC in accordance with
paragraph (k)(1) of this final rule, if sufficient data are submitted
to substantiate that the method would provide an acceptable level of
safety. We have not changed the AD in this regard.
Airplane Models Added to This AD
We have determined that Model A300 B2-1A and A300 B4-601 airplanes
were inadvertently omitted from the Applicability of the NPRM (77 FR
10409, February 22, 2012). We have added those models to the
Applicability of this AD in paragraphs (c)(1) and (c)(3) respectively.
However, none of the airplanes added to the Applicability of this AD
are on the U.S. Register. Therefore, additional notice and opportunity
for public comment before issuing this AD are unnecessary.
Explanation of Updated Credit Language
We have revised the heading and wording for paragraph (i) of this
AD to provide appropriate credit for previous accomplishment of certain
actions. This change does not affect the intent of that paragraph.
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 10409, February 22, 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 10409, February 22, 2012).
Costs of Compliance
We estimate that this AD will affect about 221 products of U.S.
registry. We also estimate that it will take up to 12 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 $225,420, or $1,020 per
product.
In addition, we estimate that any necessary follow-on actions would
take about 1 work-hour. We have no way of determining the number of
products that may need these actions.
We have received no definitive data that would enable us to provide
cost estimates for certain parts required for the on-condition actions
(replacing fuel pump canister hood halves) specified in this 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
[[Page 64703]]
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 10409, February 22,
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.
