Discussion The DGAC, which is the airworthiness authority for France, notified us that an unsafe condition may exist on certain Airbus Model A300 B2 series airplanes and A300 B4 series airplanes; Model A300 B4–600, B4– 600R, and F4–600R series airplanes, and Model C4 605R Variant F airplanes (collectively called A300–600); and Model A310 series airplanes. The DGAC advises that the existing cabin altitude pressure indicator can give a false indication of the cabin altitude especially when the pressurization system is operated in manual mode. Accidents have occurred on in-service airplanes when crewmembers forcibly initiated opening of passenger/crew doors against residual pressure (a positive pressure difference between inside the cabin and outside the cabin) causing the doors to rapidly open. In these accidents, the existing pressurization system did not indicate the presence of residual pressure in the cabin. Relevant Service Information Airbus has issued Service Bulletins A300–21–0131, Revision 01, dated January 6, 2005; A300–21–6050, Revision 01, dated December 17, 2004; and A310–21–2063, Revision 01, dated January 6, 2005. The service bulletins describe procedures for replacing the existing cabin altitude indicator in the cabin pressure control panel with a new improved cabin altitude indicator. The new cabin altitude indicator introduces a stop in the needle driving mechanism to limit the needle position near 5,000 feet in case of extreme low altitude. (A stop already exists for the ‘‘overhigh’’ altitude.) The new cabin altitude indicator is designed to prevent false interpretation of the needle position when altitude goes out of the normal range. 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–2005– 027, dated February 16, 2005, to ensure the continued airworthiness of these airplanes in France. All three service bulletins described above reference Thales Service Bulletin 37000–3–21–001, dated October 8, 2004, as an additional source of service information for replacing the cabin altitude indicator. PO 00000 Frm 00013 Fmt 4702 Sfmt 4702 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. 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 194 airplanes of U.S. registry. The proposed actions would take about 7 work hours per airplane, at an average labor rate of $65 per work hour. Required parts would cost about $1,246 per airplane. Based on these figures, the estimated cost of the proposed AD for U.S. operators is $329,994, or $1,701 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 E:\FR\FM\14SEP1.SGM 14SEP1 54323 Federal Register / Vol. 70, No. 177 / Wednesday, September 14, 2005 / Proposed Rules 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.

Discussion

    The DGAC, which is the airworthiness authority for France, notified 
us that an unsafe condition may exist on certain Airbus Model A300 B2 
series airplanes and A300 B4 series airplanes; Model A300 B4-600, B4-
600R, and F4-600R series airplanes, and Model C4 605R Variant F 
airplanes (collectively called A300-600); and Model A310 series 
airplanes. The DGAC advises that the existing cabin altitude pressure 
indicator can give a false indication of the cabin altitude especially 
when the pressurization system is operated in manual mode. Accidents 
have occurred on in-service airplanes when crewmembers forcibly 
initiated opening of passenger/crew doors against residual pressure (a 
positive pressure difference between inside the cabin and outside the 
cabin) causing the doors to rapidly open. In these accidents, the 
existing pressurization system did not indicate the presence of 
residual pressure in the cabin.

Relevant Service Information

    Airbus has issued Service Bulletins A300-21-0131, Revision 01, 
dated January 6, 2005; A300-21-6050, Revision 01, dated December 17, 
2004; and A310-21-2063, Revision 01, dated January 6, 2005. The service 
bulletins describe procedures for replacing the existing cabin altitude 
indicator in the cabin pressure control panel with a new improved cabin 
altitude indicator. The new cabin altitude indicator introduces a stop 
in the needle driving mechanism to limit the needle position near 5,000 
feet in case of extreme low altitude. (A stop already exists for the 
``overhigh'' altitude.) The new cabin altitude indicator is designed to 
prevent false interpretation of the needle position when altitude goes 
out of the normal range. 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-2005-027, dated February 16, 2005, to ensure 
the continued airworthiness of these airplanes in France.
    All three service bulletins described above reference Thales 
Service Bulletin 37000-3-21-001, dated October 8, 2004, as an 
additional source of service information for replacing the cabin 
altitude indicator.

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. 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 194 airplanes of U.S. registry. 
The proposed actions would take about 7 work hours per airplane, at an 
average labor rate of $65 per work hour. Required parts would cost 
about $1,246 per airplane. Based on these figures, the estimated cost 
of the proposed AD for U.S. operators is $329,994, or $1,701 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

[[Page 54323]]

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.

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 FAA amends Sec.  39.13 by adding the following new 
airworthiness directive (AD):

Airbus: Docket No. FAA-2005-22411; Directorate Identifier 2005-NM-
074-AD.

Comments Due Date

    (a) The Federal Aviation Administration must receive comments on 
this AD action by October 14, 2005.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to Airbus Model A300 B2-1A, B2-1C, B2K-3C, 
and B2-203 airplanes; Model A300 B4-2C, B4-103, and B4-203 
airplanes; Model A300 B4-601, B4-603, B4-620, and B4-622 airplanes; 
Model A300 B4-605R and B4-622 airplanes; Model A300 F4-605R and F4-
622R airplanes; Model A300 C4-605R Variant F airplanes; Model A310-
203, -204, -221, and -222 airplanes; and Model A310-304, -322, -324, 
and -325 airplanes; certificated in any category; except for those 
airplanes on which Airbus Modification 12857 has been incorporated 
in production.

Unsafe Condition

    (d) This AD was prompted by a report of injuries occurring on 
in-service airplanes when crewmembers forcibly initiated opening of 
passenger/crew doors against residual pressure causing the doors to 
rapidly open. We are issuing this AD to prevent injury to 
crewmembers, and subsequent damage to the airplane caused by the 
rapid opening of the door.

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.

Replacing the Cabin Altitude Indicator

    (f) Within 22 months after the effective date of this AD, 
replace the cabin altitude indicator (Part Number (P/N) 37000-3) in 
the cabin pressure control panel with a new improved cabin altitude 
indicator (P/N 37000-3-01), in accordance with the service bulletins 
specified in Table 1 of this AD, as applicable.
