ADDRESSES: For service information identified in this AD, contact Boeing Commercial Airplanes, P.O. Box 3707, Seattle, Washington 98124–2207. 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 757 airplanes. That NPRM was published in the Federal Register on January 14, 2008 (73 FR 2195). That NPRM proposed to require an inspection to determine the manufacturer and manufacture date of the oxygen masks in the passenger service units and the lavatory and attendant box assemblies, and corrective action if necessary. Comments We gave the public the opportunity to participate in developing this AD. We considered the comment received. Boeing supports the NPRM. Conclusion We reviewed the relevant data, considered the comments received, and PO 00000 Frm 00024 Fmt 4700 Sfmt 4700 determined that air safety and the public interest require adopting the AD as proposed. Costs of Compliance There are about 1,035 airplanes of the affected design in the worldwide fleet. This AD affects about 640 airplanes of U.S. registry. The required actions take about 20 work hours per airplane, for an average of 240 oxygen masks 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 $1,024,000, or $1,600 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 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.

This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as: A crack has been found in an axle adaptor during fatigue testing. It was found that the internal edges of the dowel holes did not have the correct radius and the crack had developed from the edge of one of the dowel holes. A crack in the axle adaptor can cause the axle adaptor to fail and ultimately lead to loss of [the] wheels and total loss of brake capability. We are issuing this AD to require actions to correct the unsafe condition on these products. DATES: This AD becomes effective May 19, 2008.

Airworthiness Directives; Boeing Model 757 Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Boeing Model 757 airplanes. This AD requires an inspection to determine 
the manufacturer and manufacture date of the oxygen masks in the 
passenger service units and the lavatory and attendant box assemblies, 
and corrective action if necessary. This AD results from a report that 
several passenger masks with broken in-line flow indicators were found 
following a mask deployment. We are issuing this AD to prevent the in-
line flow indicators of the passenger oxygen masks from fracturing and 
separating, which could inhibit oxygen flow to the masks and 
consequently result in exposure of the passengers and cabin attendants 
to hypoxia following a depressurization event.

DATES: This AD is effective May 19, 2008.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of May 19, 
2008.

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 757 airplanes. That NPRM was published in the 
Federal Register on January 14, 2008 (73 FR 2195). That NPRM proposed 
to require an inspection to determine the manufacturer and manufacture 
date of the oxygen masks in the passenger service units and the 
lavatory and attendant box assemblies, and corrective action if 
necessary.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comment received. Boeing supports the NPRM.

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.

Costs of Compliance

    There are about 1,035 airplanes of the affected design in the 
worldwide fleet. This AD affects about 640 airplanes of U.S. registry. 
The required actions take about 20 work hours per airplane, for an 
average of 240 oxygen masks 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 $1,024,000, or $1,600 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

    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.
