Comments will be available in the AD docket shortly after the Docket Management System receives them. Discussion The European Aviation Safety Agency (EASA), which is the airworthiness authority for the European Union, notified us that an unsafe condition may exist on certain Airbus Model A300 and A310 airplanes; and Model A300 B4– 600, B4–600R, and F4–600R series airplanes, and Model C4–605R Variant F airplanes (collectively called A300–600 series airplanes). The EASA advises it has received a report indicating that a failure of the parking brake system occurred on a Model A300–600 airplane. After the airplane had been braked to a halt with both engines running and the parking brake applied, the airplane began to move again. As engaging the parking brake inhibits all other braking modes by design, the flightcrew was unable to stop the airplane using the brake pedals. Investigation revealed that a wire intended to reduce the area of one internal port of the parking brake pressure limiter had broken and caused excess restriction of the port, which delayed the buildup of parking brake pressure. This condition, if not corrected, could cause failure of the parking braking system and interference with emergency use of the brake pedals, which could lead to airplane collision with surrounding objects or departure from the runway. Relevant Service Information We have reviewed the Airbus service bulletins described in the following table. The service bulletins describe procedures for replacing the pressure limiter of the parking brake system with a new or modified pressure limiter— modification includes removing a certain wire and installing a new pressure restrictor. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition.

As described in FAA Order 8100.14A, ‘‘Interim Procedures for Working with the European Community on Airworthiness Certification and Continued Airworthiness,’’ dated August 12, 2005, the EASA has kept the FAA informed of the situation described above. We have examined the EASA’s findings, evaluated all pertinent information, and determined that we need to issue an AD for airplanes of this type design that are certificated for operation in the United States. VerDate Aug<31>2005 14:58 Sep 25, 2006 Jkt 208001 Therefore, we are proposing this AD, which would require accomplishing the actions specified in the service information described previously. Costs of Compliance This proposed AD would affect about 229 airplanes of U.S. registry. The proposed actions would take about 2 work hours per airplane, at an average labor rate of $80 per work hour. The manufacturer states that it will supply required parts to the operators at no cost. Based on these figures, the estimated cost of the proposed AD for U.S. operators is $36,640, or $160 per airplane. 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 PO 00000 Frm 00007 Fmt 4702 Sfmt 4702 Dated February 22, 2006.

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 have determined that this proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 the proposed regulation: 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 proposed AD and placed it in the AD docket.

Discussion

    The European Aviation Safety Agency (EASA), which is the 
airworthiness authority for the European Union, notified us that an 
unsafe condition may exist on certain Airbus Model A300 and A310 
airplanes; and Model A300 B4-600, B4-600R, and F4-600R series 
airplanes, and Model C4-605R Variant F airplanes (collectively called 
A300-600 series airplanes). The EASA advises it has received a report 
indicating that a failure of the parking brake system occurred on a 
Model A300-600 airplane. After the airplane had been braked to a halt 
with both engines running and the parking brake applied, the airplane 
began to move again. As engaging the parking brake inhibits all other 
braking modes by design, the flightcrew was unable to stop the airplane 
using the brake pedals. Investigation revealed that a wire intended to 
reduce the area of one internal port of the parking brake pressure 
limiter had broken and caused excess restriction of the port, which 
delayed the buildup of parking brake pressure. This condition, if not 
corrected, could cause failure of the parking braking system and 
interference with emergency use of the brake pedals, which could lead 
to airplane collision with surrounding objects or departure from the 
runway.

Relevant Service Information

    We have reviewed the Airbus service bulletins described in the 
following table. The service bulletins describe procedures for 
replacing the pressure limiter of the parking brake system with a new 
or modified pressure limiter--modification includes removing a certain 
wire and installing a new pressure restrictor. Accomplishing the 
actions specified in the service information is intended to adequately 
address the unsafe condition.

airworthiness of these airplanes in the European Union.
    The service bulletins refer to Messier--Bugatti Service Bulletin 
C24264-32-848, dated February 15, 2006, as an additional source of 
service information for modifying the parking brake pressure limiter.

FAA's Determination and Requirements of the Proposed AD

    These airplane models are manufactured in France and are type 
certificated for operation in the United States under the provisions of 
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and 
the applicable bilateral airworthiness agreement. As described in FAA 
Order 8100.14A, ``Interim Procedures for Working with the European 
Community on Airworthiness Certification and Continued Airworthiness,'' 
dated August 12, 2005, the EASA has kept the FAA informed of the 
situation described above. We have examined the EASA's findings, 
evaluated all pertinent information, and determined that we need to 
issue an AD for airplanes of this type design that are certificated for 
operation in the United States.
    Therefore, we are proposing this AD, which would require 
accomplishing the actions specified in the service information 
described previously.

Costs of Compliance

    This proposed AD would affect about 229 airplanes of U.S. registry. 
The proposed actions would take about 2 work hours per airplane, at an 
average labor rate of $80 per work hour. The manufacturer states that 
it will supply required parts to the operators at no cost. Based on 
these figures, the estimated cost of the proposed AD for U.S. operators 
is $36,640, or $160 per airplane.

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 have determined that this proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 the proposed 
regulation:
    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 proposed AD and placed it in the AD docket. See the 
ADDRESSES section for a location to examine the regulatory evaluation.

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Safety.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    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]

    2. The Federal Aviation Administration (FAA) amends Sec.  39.13 by 
adding the following new airworthiness directive (AD):

Airbus: Docket No. FAA-2006-25891; Directorate Identifier 2006-NM-
186-AD.

Comments Due Date

    (a) The FAA must receive comments on this AD action by October 
26, 2006.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Airbus Model A300 and A310 airplanes; and

605R, F4-622R, and C4-605R Variant F airplanes; certificated in any 
category; except for airplanes on which Airbus Modification 12994 
has been embodied in production.

Unsafe Condition

    (d) This AD results from a report indicating that failure of the 
parking brake system occurred on a Model A300-600 airplane. We are 
issuing this AD to prevent failure of the parking braking system and 
interference with emergency use of the brake pedals, which could 
lead to airplane collision with surrounding objects or departure 
from the runway.

Compliance

    (e) You are responsible for having the actions required by this 
AD performed within the compliance times specified, unless the 
actions have already been done.

Pressure Limiter Replacement

    (f) Within 18 months after the effective date of this AD, 
replace the pressure limiter of the parking brake system with a new 
or modified pressure limiter having part number (P/N) C24264-303 or 
C24264004-1, as applicable, in accordance with the Accomplishment 
Instructions of the applicable service bulletin specified in Table 1
