ACTION: Final rule. AGENCY: We are adopting a new airworthiness directive (AD) for certain Model 747 airplanes. This AD requires inspecting to verify the part number of the low-pressure flex-hoses of the crew oxygen system installed under the oxygen mask stowage boxes in the flight deck, and replacing the flex-hose with a new non-conductive low-pressure flexhose if necessary. This AD results from reports of low-pressure flex-hoses of the crew oxygen system that burned through due to inadvertent electrical current from a short circuit in the audio select panel. We are issuing this AD to prevent inadvertent electrical current, which can cause the low-pressure flexhoses of the crew oxygen system to melt or burn, causing oxygen system leakage and smoke or fire. DATES: This AD is effective September 9, 2010. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in the AD as of September 9, 2010.

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 Model 747 airplanes. That NPRM was published in the Federal Register on January 22, 2010 (75 FR 3658). That NPRM proposed to require inspecting to verify the part number of the low-pressure flex-hoses of the crew oxygen system installed under the oxygen mask stowage boxes in the flight deck, and replacing the flex-hose with a new non-conductive low-pressure flexhose if necessary. Comments We gave the public the opportunity to participate in developing this AD. We considered the comments received. Support for the NPRM Boeing concurs with the contents of the NPRM, and the Air Line Pilots Association, International (ALPA) supports the intent of the NPRM. Request To Shorten Compliance Time ALPA requests that the 36-month compliance time specified in the NPRM be shortened given the potential consequence of an oxygen-fed fire in the vicinity of the flightcrew station. We do not agree. In developing an appropriate compliance time, we considered the safety implications, parts availability, and normal maintenance schedules for timely accomplishment of replacement of the fasteners. Further, we arrived at the compliance time with manufacturer concurrence. In consideration of all of these factors, we determined that the compliance time, as proposed, represents an appropriate interval in which the inspections can be done in a timely manner within the fleet, while still maintaining an adequate level of safety. Operators are always permitted to accomplish the requirements of an AD at a time earlier than the specified compliance time; therefore, an operator may choose to do E:\FR\FM\05AUR1.SGM 05AUR1 Federal Register / Vol. 75, No. 150 / Thursday, August 5, 2010 / Rules and Regulations the inspection before 36 months in order to accomplish the requirements of this AD. If additional data are presented that would justify a shorter compliance time, we may consider further rulemaking on this issue. 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 as proposed. Explanation of Change to Costs of Compliance Since issuance of the NPRM, we have increased the labor rate used in the Costs of Compliance from $80 per workhour to $85 per work-hour. The Costs of Compliance information, below, reflects this increase in the specified hourly labor rate. 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, (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 Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows: wwoods2 on DSK1DXX6B1PROD with RULES_PART 1 Costs of Compliance We estimate that this AD will affect 211 airplanes of U.S. registry. We also estimate that it will take 1 work-hour per product to comply with this AD. The average labor rate is $85 per workhour. Based on these figures, we estimate the cost of this proposed AD to the U.S. operators to be $17,935, or $85 per product. ■ 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 Regulatory Findings This AD will not have federalism implications under Executive Order 13132.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Model 747 airplanes. This AD requires inspecting to verify the part 
number of the low-pressure flex-hoses of the crew oxygen system 
installed under the oxygen mask stowage boxes in the flight deck, and 
replacing the flex-hose with a new non-conductive low-pressure flex-
hose if necessary. This AD results from reports of low-pressure flex-
hoses of the crew oxygen system that burned through due to inadvertent 
electrical current from a short circuit in the audio select panel. We 
are issuing this AD to prevent inadvertent electrical current, which 
can cause the low-pressure flex-hoses of the crew oxygen system to melt 
or burn, causing oxygen system leakage and smoke or fire.

DATES: This AD is effective September 9, 2010.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in the AD as of September 9, 
2010.

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 Model 747 airplanes. That NPRM was published in the Federal 
Register on January 22, 2010 (75 FR 3658). That NPRM proposed to 
require inspecting to verify the part number of the low-pressure flex-
hoses of the crew oxygen system installed under the oxygen mask stowage 
boxes in the flight deck, and replacing the flex-hose with a new non-
conductive low-pressure flex-hose if necessary.

Comments

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

Support for the NPRM

    Boeing concurs with the contents of the NPRM, and the Air Line 
Pilots Association, International (ALPA) supports the intent of the 
NPRM.

Request To Shorten Compliance Time

    ALPA requests that the 36-month compliance time specified in the 
NPRM be shortened given the potential consequence of an oxygen-fed fire 
in the vicinity of the flightcrew station.
    We do not agree. In developing an appropriate compliance time, we 
considered the safety implications, parts availability, and normal 
maintenance schedules for timely accomplishment of replacement of the 
fasteners. Further, we arrived at the compliance time with manufacturer 
concurrence. In consideration of all of these factors, we determined 
that the compliance time, as proposed, represents an appropriate 
interval in which the inspections can be done in a timely manner within 
the fleet, while still maintaining an adequate level of safety. 
Operators are always permitted to accomplish the requirements of an AD 
at a time earlier than the specified compliance time; therefore, an 
operator may choose to do

[[Page 47209]]

the inspection before 36 months in order to accomplish the requirements 
of this AD. If additional data are presented that would justify a 
shorter compliance time, we may consider further rulemaking on this 
issue. 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 as proposed.

Explanation of Change to Costs of Compliance

    Since issuance of the NPRM, we have increased the labor rate used 
in the Costs of Compliance from $80 per work-hour to $85 per work-hour. 
The Costs of Compliance information, below, reflects this increase in 
the specified hourly labor rate.

Costs of Compliance

    We estimate that this AD will affect 211 airplanes of U.S. 
registry. We also estimate that it will take 1 work-hour per product to 
comply with this AD. The average labor rate is $85 per work-hour. Based 
on these figures, we estimate the cost of this proposed AD to the U.S. 
operators to be $17,935, or $85 per product.

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

    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,
    (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.

    (c) This AD applies to The Boeing Company Model 747-100, 747-
100B, 747-100B SUD, 747-200B, 747-200C, 747-200F, 747-300, 747-400,

Subject

    (d) Air Transport Association (ATA) of America Code 35: Oxygen.

Unsafe Condition

    (e) This AD results from reports of low-pressure flex-hoses of 
the crew oxygen system that burned through due to inadvertent 
electrical current from a short circuit in the audio select panel. 
The Federal Aviation Administration is issuing this AD to prevent 
inadvertent electrical current, which can cause the low-pressure 
flex-hoses of the crew oxygen system to melt or burn, resulting in 
oxygen system leakage and smoke or fire.

Compliance

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

Inspection

    (g) Within 36 months after the effective date of this AD, do an 
inspection to determine whether any low-pressure flex-hose of the 
crew oxygen system installed under the oxygen mask stowage box in 
the flight deck has a part number identified in Table 1 of this AD. 
A review of airplane maintenance records is acceptable in lieu of 
this inspection if the part number of the low-pressure flex-hoses of 
the crew oxygen system can be conclusively determined from that 
review.
    (1) For any hose having a part number identified in Table 1 of 
this AD, before further flight, replace the hose with a new or 
serviceable part, in accordance with the Accomplishment Instructions 
of Boeing Service Bulletin 747-35A2101, Revision 1, dated May 15, 
2003.
    (2) For any hose not having a part number identified in Table 1 
of this AD, no further action is required by this paragraph.
