Discussion An investigation of a service problem revealed that detrimental effects could occur during flight on certain Boeing Model 777 airplanes with certain airplane information management system (AIMS) software. The following PO 00000 Frm 00001 Fmt 4702 Sfmt 4702 airplane effects could potentially occur: A false measure of cabin pressure by the left air supply and cabin pressure controller (ASCPC) could result in an unannunciated loss of cabin pressure. If an undetected loss of pressure event were to cause an unsafe pressure in the cabin, the flightcrew could become incapacitated. Relevant Service Information We have reviewed Boeing Alert Service Bulletin 777–31A0119, Revision 1, dated March 27, 2007; and Boeing Alert Service Bulletin 777–31A0120, Revision 1, dated March 23, 2007. Service Bulletin 777–31A0119 describes procedures for installing the AIMS–1 Blockpoint 2006 (BP06) operational software in the AIMS–1 hardware. Service Bulletin 777–31A0120 describes procedures for installing the AIMS–2 BP06 operational software in the AIMS– 2 hardware. Concurrent Service Bulletins Boeing Alert Service Bulletin 777– 31A0119 recommends prior or concurrent accomplishment of Boeing Special Attention Service Bulletin 777– 31–0098, Revision 1, dated May 3, 2007. That service bulletin describes procedures for installing the AIMS–1 Blockpoint 2005A (BP05A) operational software. Boeing Alert Service Bulletin 777–31A0120 recommends prior or concurrent accomplishment of Boeing Special Attention Service Bulletin 777– 31–0097, Revision 3, dated February 22, 2007. That service bulletin describes procedures for installing the AIMS–2 BP05A operational software. FAA’s Determination and Requirements of the Proposed AD We have evaluated all pertinent information and identified an unsafe condition that is likely to exist or develop on other airplanes of this same type design. For this reason, we are proposing this AD, which would require accomplishing the actions specified in the service information described previously. Costs of Compliance There are about 142 airplanes of the affected design in the worldwide fleet. This proposed AD would affect about 2 airplanes of U.S. registry. The proposed actions would take between 1 and 4 work hours per airplane, at an average labor rate of $80 per work hour. Based E:\FR\FM\28NOP1.SGM 28NOP1 67264 Federal Register / Vol. 72, No. 228 / Wednesday, November 28, 2007 / Proposed Rules on these figures, the estimated cost of the proposed AD for U.S. operators is between $160 and $640, or between $80 and $320 per airplane. Authority for This Rulemaking 1. The authority citation for part 39 continues to read as follows: Authority: 49 U.S.C. 106(g), 40113, 44701. 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. § 39.13 [Amended] 2. The Federal Aviation Administration (FAA) amends § 39.13 by adding the following new airworthiness directive (AD): Boeing: Docket No. FAA–2007–0254; Directorate Identifier 2007–NM–209–AD. Comments Due Date (a) The FAA must receive comments on this AD action by January 14, 2008. Affected ADs (b) None.

Unsafe Condition (d) This AD results from an investigation that revealed that detrimental effects could occur on certain airplane information management system (AIMS) software during flight. We are issuing this AD to prevent an unannunciated loss of cabin pressure. If an undetected loss of pressure event were to cause an unsafe pressure in the cabin, the flight crew could become incapacitated. 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. The Proposed Amendment Software Installation (f) Within 15 months after the effective date of this AD, do the actions specified in paragraphs (f)(1) and (f)(2) of this AD, as applicable. (1) Install the AIMS Blockpoint 2006 (BP06) operational software by doing all the actions in accordance with the Accomplishment Instructions of Boeing Alert Service Bulletin 777–31A0119, Revision 1, dated March 27, 2007; or Boeing Alert Service Bulletin 777–31A0120, Revision 1, dated March 23, 2007; as applicable.

Discussion

    An investigation of a service problem revealed that detrimental 
effects could occur during flight on certain Boeing Model 777 airplanes 
with certain airplane information management system (AIMS) software. 
The following airplane effects could potentially occur: A false measure 
of cabin pressure by the left air supply and cabin pressure controller 
(ASCPC) could result in an unannunciated loss of cabin pressure. If an 
undetected loss of pressure event were to cause an unsafe pressure in 
the cabin, the flightcrew could become incapacitated.

Relevant Service Information

    We have reviewed Boeing Alert Service Bulletin 777-31A0119, 
Revision 1, dated March 27, 2007; and Boeing Alert Service Bulletin 
777-31A0120, Revision 1, dated March 23, 2007. Service Bulletin 777-
31A0119 describes procedures for installing the AIMS-1 Blockpoint 2006 
(BP06) operational software in the AIMS-1 hardware. Service Bulletin 
777-31A0120 describes procedures for installing the AIMS-2 BP06 
operational software in the AIMS-2 hardware.

Concurrent Service Bulletins

    Boeing Alert Service Bulletin 777-31A0119 recommends prior or 
concurrent accomplishment of Boeing Special Attention Service Bulletin 
777-31-0098, Revision 1, dated May 3, 2007. That service bulletin 
describes procedures for installing the AIMS-1 Blockpoint 2005A (BP05A) 
operational software. Boeing Alert Service Bulletin 777-31A0120 
recommends prior or concurrent accomplishment of Boeing Special 
Attention Service Bulletin 777-31-0097, Revision 3, dated February 22, 
2007. That service bulletin describes procedures for installing the 
AIMS-2 BP05A operational software.

FAA's Determination and Requirements of the Proposed AD

    We have evaluated all pertinent information and identified an 
unsafe condition that is likely to exist or develop on other airplanes 
of this same type design. For this reason, we are proposing this AD, 
which would require accomplishing the actions specified in the service 
information described previously.

Costs of Compliance

    There are about 142 airplanes of the affected design in the 
worldwide fleet. This proposed AD would affect about 2 airplanes of 
U.S. registry. The proposed actions would take between 1 and 4 work 
hours per airplane, at an average labor rate of $80 per work hour. 
Based

[[Page 67264]]

on these figures, the estimated cost of the proposed AD for U.S. 
operators is between $160 and $640, or between $80 and $320 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.
