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 all
Airbus Model A300 B4-600, B4-600R, and F4-600R series airplanes, and
Model C4-605R Variant F airplanes (collectively called A300-600 series
airplanes), and Model A310 series airplanes. This AD was prompted by a
report of a crack in the selector valve pipe of the forward cargo door
located in the avionics bay opposite the line replaceable unit racking.
This AD requires replacing a certain aluminum high pressure pipe with a
new corrosion resistant stainless steel pipe. We are issuing this AD to
prevent cracking in the selector valve pipe of the forward cargo door
which could impact the 90 VU avionics line replaceable unit, and could
result in multiple computer failures, affecting flight safety.
DATES: This AD becomes effective April 25, 2012.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of April 25,
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 December 22, 2011
(76 FR 79558). That NPRM proposed to require replacing a certain
aluminum high pressure pipe with a new corrosion resistant stainless
steel pipe. The MCAI states:
An A300-600 operator has reported a hydraulic leak at the
forward cargo door area. After further investigation, the forward
cargo door selector valve pipe Part Number (P/N) A5231006100300,
located in the avionics bay opposite to Line Replaceable Unit (LRU)
racking, was found cracked.
This condition, if not detected and corrected, can impact the 90
VU avionics LRU, which could result in multiple computer failures,
affecting flight safety.
For the reasons described above, this AD requires the
replacement of the aluminum pipe P/N A5231006100300 with a stainless
steel pipe P/N A5231007000600.
This [EASA] AD has been corrected to make clear that the use of
Airbus SB A310-
[[Page 16431]]
52-2067 and Airbus SB [service bulletin] A300-52-6065 at original
issue is acceptable to comply with paragraph (1) of this [EASA] AD,
unless, inadvertently, the high pressure pipe P/N A5231007000600 has
been replaced in service, after original issue of the SB's
accomplishment, with P/N A5231006100300.
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 received no comments on the NPRM (76 FR 79558, December 22,
2011) or on the determination of the cost to the public.
Changes to AD
We have clarified that the models affected by Airbus Mandatory
Service Bulletin A300-52-6065, Revision 01, dated July 5, 2010, are
Model A300-600 series airplanes. We have changed paragraph (g) of this
AD accordingly.
We have revised the heading for and the wording in paragraph (j) of
this AD; this change has not changed the intent of that paragraph.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed except for
minor editorial changes and/or the changes described previously. We
have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM (76 FR 79558, December 22, 2011) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (76 FR 79558, December 22, 2011).
Costs of Compliance
We estimate that this AD will affect 152 products of U.S. registry.
We also estimate that 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. Required parts will cost about $0 per product.
Where the service information lists required parts costs that are
covered under warranty, we have assumed that there will be no charge
for these parts. As we do not control warranty coverage for affected
parties, some parties may incur costs higher than estimated here. Based
on these figures, we estimate the cost of this AD to the U.S. operators
to be $51,680, or $340 per product.
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 http://www.regulations.gov; 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 (76 FR 79558, December 22,
2011), 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.
