14 CFR Part 39
[Docket No. FAA-2007-28922; Directorate Identifier 2007-NM-132-AD;
Amendment 39-15225; AD 2007-21-07]
RIN 2120-AA64
Airworthiness Directives; Airbus Model A310 Series Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for the
products listed above. This AD results from mandatory continuing
airworthiness information (MCAI) originated by an aviation authority of
another country to identify and correct an unsafe condition on an
aviation product. The MCAI describes the unsafe condition as:
An incident occurred on one A300-600 aircraft at parking brake
application. Both engines were running, the aircraft started moving
again despite parking brake application. Captain tried to stop the
aircraft via the pedals but, as the parking brake selector valve was
selected, the aircraft could not be stopped (as per design,
activation of the parking brake inhibits the other braking modes,
and consequently prevents the recovery of the normal braking through
the pedals). As part of the investigation, the pressure limiter was
removed and examined. The expertise revealed a metallic wire aimed
at reducing the section of one port of this equipment was found
broken. A part of this wire partially obstructed the hole receiving
this wire, thus delaying the build up of parking brake pressure.
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective November 20, 2007.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of November 20,
2007.

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 August 16, 2007 (72
FR 45976). That NPRM proposed to correct an unsafe condition for the
specified products. The MCAI states:
An incident occurred on one A300-600 aircraft at parking brake
application. Both engines were running, the aircraft started moving
again despite parking brake application. Captain tried to stop the
aircraft via the pedals but, as the parking brake selector valve was
selected, the aircraft could not be stopped (as per design,
activation of the parking brake inhibits the other braking modes,
and consequently prevents the recovery of the normal braking through
the pedals). As part of the investigation, the pressure limiter was
removed and examined. The expertise revealed a metallic wire aimed
at reducing the section of one port of this equipment was found
broken. A part of this wire partially obstructed the hole receiving
this wire, thus delaying the build up of parking brake pressure. In
order to avoid recurrence of the failure mode described above, EASA
issued Airworthiness Directive (AD) 2006-0178 to require the
replacement of the parking brake pressure limiter (FIN 323292).
During embodiment of SB (Service Bulletin) 32-2133 on an A310 as
per AD 2006-0178 (EASA AD 2006-0178 corresponds to FAA AD 2007-02-
21, amendment 39-14908), an operator reported that the modified
pressure limiter could not be fitted. Subsequent investigation
concluded that A310 installation being slightly different from A300-
600 aircraft, the approved solution was not directly adaptable to
A310 aircraft.
[[Page 58490]]
* * * This new AD, dealing with the same subject, requires the
replacement of the brake pressure limiter by accomplishment of
Airbus SB A310-32-2133, which has been revised to include the
adaptation kit for A310 aircraft.
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 or on the determination of
the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed.
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have required different actions in this AD from those
in the MCAI in order to follow our FAA policies. Any such differences
are highlighted in a NOTE within the AD.
Costs of Compliance
We estimate that this AD will affect 68 products of U.S. registry.
We also estimate that it will take about 6 work-hours per product to
comply with the basic requirements of this AD. The average labor rate
is $80 per work-hour. Labor costs may be covered under warranty as
described in the service information. 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 $32,640, or $480 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 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); and
3. 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, 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.

1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by adding the following new AD:
2007-21-07 Airbus: Amendment 39-15225. Docket No. FAA-2007-28922;
Directorate Identifier 2007-NM-132-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective November
20, 2007.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Airbus Model A310 series airplanes,
certificated in any category, except airplanes on which Airbus
Service Bulletin A310-32-2133, Revision 02, dated February 26, 2007,
has been embodied in service.
Subject
(d) Air Transport Association (ATA) of America Code 32: Landing
gear.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
An incident occurred on one A300-600 aircraft at parking brake
application. Both engines were running, the aircraft started moving
again despite parking brake application. Captain tried to stop the
aircraft via the pedals but, as the parking brake selector valve was
selected, the aircraft could not be stopped (as per design,
activation of the parking brake inhibits the other braking modes,
and consequently prevents the recovery of the normal braking through
the pedals). As part of the investigation, the pressure limiter was
removed and examined. The expertise revealed a metallic wire aimed
at reducing the section of one port of this equipment was found
broken. A part of this wire partially obstructed the hole receiving
this wire, thus delaying the build up of parking brake pressure. In
order to avoid recurrence of the failure mode described above, EASA
(European Aviation Safety Agency), issued Airworthiness Directive
(AD) 2006-0178 to require the replacement of the parking brake
pressure limiter (FIN 323292).
During embodiment of SB (Service Bulletin) 32-2133 on an A310 as
per AD 2006-0178 [EASA AD 2006-0178 corresponds to FAA AD 2007-02-
21, amendment 39-14908], an operator reported that the modified
pressure limiter could not be fitted. Subsequent investigation
concluded that A310 installation being slightly different from A300-
600 aircraft, the approved solution was not directly adaptable to
A310 aircraft.
* * * This new AD, dealing with the same subject, requires the
replacement of the brake
[[Page 58491]]
pressure limiter by accomplishment of Airbus SB A310-32-2133, which
has been revised to include the adaptation kit for A310 aircraft.
Actions and Compliance
(f) Unless already done, do the following actions.
(1) Within 10 months after the effective date of this AD,
replace the parking brake pressure limiter (FIN 323292), in
accordance with the instructions given in Airbus Service Bulletin
A310-32-2133, Revision 02, dated February 26, 2007.
(2) [Reserved]
