Comments will be available in the AD docket shortly after the DMS receives them. Discussion ´ ´ The Direction Generale de l’Aviation Civile (DGAC), which is the airworthiness authority for France, notified us that an unsafe condition may exist on certain Airbus Model A319, A320, and A321 series airplanes. The DGAC advises that one operator reported failure of the parking brake while the airplane was on the holding point of the runway before takeoff, leading to a runway departure. The flight crew tried to stop the airplane with the brake pedals, but were unsuccessful. Additional reports were received from other operators of incidents of braking difficulty after the parking brake was selected. Analysis showed that the airplane is designed so that normal braking is inhibited when the parking brake is selected. In the case of parking brake loss, a flight crew operations manual (FCOM) procedure recommends immediately releasing the parking brake handle to restore braking through the pedals; however, excess pilot workload can preclude using that procedure. When the parking brake lever is selected to the ON position, the parking brake selector valve sends a signal to the braking and steering control unit, which inhibits the normal braking system. These conditions, if not corrected, could result in possible runway departure in the event of failure of the parking brake. Relevant Service Information Airbus has issued Service Bulletin A320–32–1201, Revision 01, dated May 29, 2002. The service bulletin describes procedures for modifying the parking brake system (including installing VerDate jul<14>2003 15:58 Apr 05, 2005 Jkt 205001 placards) to automatically restore the normal parking brake if the parking brake pressure decreases below a certain threshold. The service bulletin also describes procedures for performing operational tests after accomplishing the modification. Accomplishing the actions specified in the service information is intended to adequately address the unsafe condition. The DGAC mandated the service information and issued French airworthiness directive F–2004–137, dated November 10, 2004, to ensure the continued airworthiness of these airplanes in France. 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 § 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement. Pursuant to this bilateral airworthiness agreement, the DGAC has kept the FAA informed of the situation described above. We have examined the DGAC’s findings, evaluated all pertinent information, and determined that we need to issue an AD for products 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. 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. See the ADDRESSES section for a location to examine the regulatory evaluation. List of Subjects in 14 CFR Part 39 Costs of Compliance This proposed AD would affect about 357 airplanes of U.S. registry. The proposed modification would take about 23 work hours per airplane, at an average labor rate of $65 per work hour. Required parts would cost about $5,600 per airplane. Based on these figures, the estimated cost of the proposed modification for U.S. operators is $2,532,915, or $7,095 per airplane. Air transportation, Aircraft, Aviation safety, Safety.

Discussion

    The Direction G[eacute]n[eacute]rale de l'Aviation Civile (DGAC), 
which is the airworthiness authority for France, notified us that an 
unsafe condition may exist on certain Airbus Model A319, A320, and A321 
series airplanes. The DGAC advises that one operator reported failure 
of the parking brake while the airplane was on the holding point of the 
runway before takeoff, leading to a runway departure. The flight crew 
tried to stop the airplane with the brake pedals, but were 
unsuccessful. Additional reports were received from other operators of 
incidents of braking difficulty after the parking brake was selected. 
Analysis showed that the airplane is designed so that normal braking is 
inhibited when the parking brake is selected. In the case of parking 
brake loss, a flight crew operations manual (FCOM) procedure recommends 
immediately releasing the parking brake handle to restore braking 
through the pedals; however, excess pilot workload can preclude using 
that procedure. When the parking brake lever is selected to the ON 
position, the parking brake selector valve sends a signal to the 
braking and steering control unit, which inhibits the normal braking 
system. These conditions, if not corrected, could result in possible 
runway departure in the event of failure of the parking brake.

Relevant Service Information

    Airbus has issued Service Bulletin A320-32-1201, Revision 01, dated 
May 29, 2002. The service bulletin describes procedures for modifying 
the parking brake system (including installing placards) to 
automatically restore the normal parking brake if the parking brake 
pressure decreases below a certain threshold. The service bulletin also 
describes procedures for performing operational tests after 
accomplishing the modification. Accomplishing the actions specified in 
the service information is intended to adequately address the unsafe 
condition. The DGAC mandated the service information and issued French 
airworthiness directive F-2004-137, dated November 10, 2004, to ensure 
the continued airworthiness of these airplanes in France.

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 
Sec.  21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the 
applicable bilateral airworthiness agreement. Pursuant to this 
bilateral airworthiness agreement, the DGAC has kept the FAA informed 
of the situation described above. We have examined the DGAC's findings, 
evaluated all pertinent information, and determined that we need to 
issue an AD for products 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 357 airplanes of U.S. registry. 
The proposed modification would take about 23 work hours per airplane, 
at an average labor rate of $65 per work hour. Required parts would 
cost about $5,600 per airplane. Based on these figures, the estimated 
cost of the proposed modification for U.S. operators is $2,532,915, or 
$7,095 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. See the ADDRESSES section for a location 
to examine the regulatory evaluation.
