ACTION: Final rule. SUMMARY: We are adopting a new airworthiness directive (AD) for certain Boeing Model 777 airplanes. This AD requires installing software upgrades to the airplane information management system (AIMS) located in the flight compartment. This AD results from an investigation that revealed that detrimental effects could occur on certain 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. DATES: This AD is effective April 2, 2009. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of April 2, 2009.

SUPPLEMENTARY INFORMATION: Discussion We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an airworthiness directive (AD) that would apply to certain Boeing Model 777 airplanes. That NPRM was published in the Federal Register on November 28, 2007 (72 FR 67263). That NPRM proposed to require installing software upgrades to the airplane information management system (AIMS) located in the flight compartment. Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received. Request To Incorporate Revised Service Information Boeing asks that we reference Boeing Service Bulletins 777–31A0119 and 777–31A0120, both Revision 2, both dated June 12, 2008, in the final rule. 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; were referenced in the NPRM as the appropriate sources of service information for accomplishing certain actions. Revision 2 of the service bulletins clarifies the procedures for upgrading to the Airplane Information Management System—1 (AIMS–1) Blockpoint 2006 (BP06) operational software. We have reviewed Revision 2 of these service bulletins and we agree with the commenter, since no additional work is necessary on airplanes changed in accordance with Revision 1 of the referenced service information; Revision 2 of these service bulletins just provides certain clarifications. We have added Revision 2 of these service bulletins to the applicability specified in paragraph (c) of this AD, and to paragraph (f)(1) of this AD, as the appropriate sources of service information for accomplishing the actions specified. In addition, we have added credit for accomplishing the E:\FR\FM\26FER1.SGM 26FER1 Federal Register / Vol. 74, No. 37 / Thursday, February 26, 2009 / Rules and Regulations actions using Revision 1 of these service bulletins to paragraph (g) of this AD. Request To Update Number of U.S. Airplanes Boeing also asks that we change the number of U.S. airplanes affected by this AD from 2 to 4 to reflect the production deliveries of airplanes with software requiring an update. Boeing states that there were about 142 AIMS– 2 airplanes that were delivered in production on which the affected software design was incorporated. Boeing also recommends adding a statement that about 230 additional airplanes (of which an estimated 70 of those airplanes are of U.S. registry) on which AIMS–1 software has been incorporated will require an update to BP06. We partially agree with the commenter. Since the total number of airplanes of the affected design in the worldwide fleet has not increased, we agree to change the number of U.S. airplanes affected by this AD from 2 to 4. The 2 additional U.S.-registered airplanes in need of the software update have been added to the Costs of Compliance section in this AD. We do not agree to include the statements provided by the commenter, as that language would be added to the Discussion section of the NPRM, which is not carried over to this final rule. We have made no change to the AD in this regard. Request To Reduce Compliance Time Air Line Pilots Association, International (ALPA), asks that the 15month compliance time specified in paragraph (f) of the NPRM be reduced. ALPA states that, given the potentially serious consequences of an undetected loss of pressurization, the number of affected aircraft, and the time required for installation of the software, a shorter compliance time should be imposed. We do not agree to reduce the compliance time specified in paragraph (f) of this AD. In developing the compliance time for this AD action, we considered not only the safety implications of the identified unsafe condition, but the average utilization rate of the affected fleet and the practical aspects of installing the software during regular maintenance periods. In addition, we considered the manufacturer’s recommendation for an appropriate compliance time. After considering all the available information, we determined that the 15month compliance time represents an appropriate interval of time in which the required actions can be performed in VerDate Nov<24>2008 14:57 Feb 25, 2009 Jkt 217001 a timely manner within the affected fleet, while still maintaining an adequate level of safety. We have not changed the AD in this regard. Conclusion We reviewed the relevant data, considered the comments received, and determined that air safety and the public interest require adopting the AD with the changes described previously. We also determined that these changes will not increase the economic burden on any operator or increase the scope of the AD. Costs of Compliance 8727 (2) Is not a ‘‘significant rule’’ under 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. You can find our regulatory evaluation and the estimated costs of compliance in the AD Docket. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. Adoption of the Amendment There are about 142 airplanes of the affected design in the worldwide fleet. This AD affects 4 airplanes of U.S. registry. The actions take between 1 and 4 work hours per airplane, at an average labor rate of $80 per work hour. Based on these figures, the estimated cost of the AD for U.S. operators is between $320 and $1,280, or between $80 and $320 per airplane. Accordingly, under the authority delegated to me by the Administrator, the FAA amends 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. 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. § 39.13 [Amended] 2. The FAA amends § 39.13 by adding the following new AD: ■ 2009–02–05 Boeing: Amendment 39–15795. Docket No. FAA–2007–0254; Directorate Identifier 2007–NM–209–AD. Effective Date (a) This airworthiness directive (AD) is effective April 2, 2009. Affected ADs (b) None. Applicability (c) This AD applies to Boeing Model 777– 200, –200LR, –300, and –300ER series airplanes, certificated in any category; as identified in Boeing Service Bulletins 777– 31A0119 and 777–31A0120, both Revision 2, both dated June 12, 2008. Regulatory Findings 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 that this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, 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.

ACTION: Final rule. SUMMARY: The FAA is superseding an existing airworthiness directive (AD) that applies to all Airbus Model A310 series airplanes. That AD currently requires repetitive detailed inspections to detect cracks propagating from the VerDate Nov<24>2008 14:57 Feb 25, 2009 Jkt 217001 fastener holes that attach the left- and right-hand pick-up angles at frame 40 to the wing lower skin and fuselage panel, and corrective actions if necessary. This new AD revises the intervals for accomplishing the repetitive detailed inspections and provides for an optional terminating modification for the repetitive inspections. This new AD also revises the applicability of the AD to remove certain airplanes. This AD results from mandatory continuing airworthiness information originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. We are issuing this AD to prevent reduced structural integrity of the airplane due to fatigue damage, and consequent cracking of the pick-up angles at frame 40.

Airworthiness Directives; Boeing Model 777 Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Boeing Model 777 airplanes. This AD requires installing software 
upgrades to the airplane information management system (AIMS) located 
in the flight compartment. This AD results from an investigation that 
revealed that detrimental effects could occur on certain 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.

DATES: This AD is effective April 2, 2009.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of April 2, 
2009.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an airworthiness directive (AD) that would apply to 
certain Boeing Model 777 airplanes. That NPRM was published in the 
Federal Register on November 28, 2007 (72 FR 67263). That NPRM proposed 
to require installing software upgrades to the airplane information 
management system (AIMS) located in the flight compartment.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comments received.

Request To Incorporate Revised Service Information

    Boeing asks that we reference Boeing Service Bulletins 777-31A0119 
and 777-31A0120, both Revision 2, both dated June 12, 2008, in the 
final rule. 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; were referenced in the NPRM as the 
appropriate sources of service information for accomplishing certain 
actions. Revision 2 of the service bulletins clarifies the procedures 
for upgrading to the Airplane Information Management System--1 (AIMS-1) 
Blockpoint 2006 (BP06) operational software.
    We have reviewed Revision 2 of these service bulletins and we agree 
with the commenter, since no additional work is necessary on airplanes 
changed in accordance with Revision 1 of the referenced service 
information; Revision 2 of these service bulletins just provides 
certain clarifications. We have added Revision 2 of these service 
bulletins to the applicability specified in paragraph (c) of this AD, 
and to paragraph (f)(1) of this AD, as the appropriate sources of 
service information for accomplishing the actions specified. In 
addition, we have added credit for accomplishing the

[[Page 8727]]

actions using Revision 1 of these service bulletins to paragraph (g) of 
this AD.

Request To Update Number of U.S. Airplanes

    Boeing also asks that we change the number of U.S. airplanes 
affected by this AD from 2 to 4 to reflect the production deliveries of 
airplanes with software requiring an update. Boeing states that there 
were about 142 AIMS-2 airplanes that were delivered in production on 
which the affected software design was incorporated. Boeing also 
recommends adding a statement that about 230 additional airplanes (of 
which an estimated 70 of those airplanes are of U.S. registry) on which 
AIMS-1 software has been incorporated will require an update to BP06.
    We partially agree with the commenter.
    Since the total number of airplanes of the affected design in the 
worldwide fleet has not increased, we agree to change the number of 
U.S. airplanes affected by this AD from 2 to 4. The 2 additional U.S.-
registered airplanes in need of the software update have been added to 
the Costs of Compliance section in this AD.
    We do not agree to include the statements provided by the 
commenter, as that language would be added to the Discussion section of 
the NPRM, which is not carried over to this final rule. We have made no 
change to the AD in this regard.

Request To Reduce Compliance Time

    Air Line Pilots Association, International (ALPA), asks that the 
15-month compliance time specified in paragraph (f) of the NPRM be 
reduced. ALPA states that, given the potentially serious consequences 
of an undetected loss of pressurization, the number of affected 
aircraft, and the time required for installation of the software, a 
shorter compliance time should be imposed.
    We do not agree to reduce the compliance time specified in 
paragraph (f) of this AD. In developing the compliance time for this AD 
action, we considered not only the safety implications of the 
identified unsafe condition, but the average utilization rate of the 
affected fleet and the practical aspects of installing the software 
during regular maintenance periods. In addition, we considered the 
manufacturer's recommendation for an appropriate compliance time. After 
considering all the available information, we determined that the 15-
month compliance time represents an appropriate interval of time in 
which the required actions can be performed in a timely manner within 
the affected fleet, while still maintaining an adequate level of 
safety. We have not changed the AD in this regard.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
the AD with the changes described previously. We also determined that 
these changes will not increase the economic burden on any operator or 
increase the scope of the AD.

Costs of Compliance

    There are about 142 airplanes of the affected design in the 
worldwide fleet. This AD affects 4 airplanes of U.S. registry. The 
actions take between 1 and 4 work hours per airplane, at an average 
labor rate of $80 per work hour. Based on these figures, the estimated 
cost of the AD for U.S. operators is between $320 and $1,280, 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
