14 CFR Part 39

[Docket No. FAA-2013-0465; Directorate Identifier 2012-NM-085-AD; 
Amendment 39-17617; AD 2013-20-11]

Airworthiness Directives; Airbus Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for all 
Airbus Model A318, A319, A320, and A321 series airplanes. This AD was 
prompted by a determination that oxygen generators installed on a 
certain batch of passenger emergency oxygen container assemblies might 
become detached by extreme pulling of the mask tube at the end of the 
oxygen supply causing a high temperature oxygen generator and mask to 
fall down. This AD requires modifying the passenger emergency oxygen 
container assembly. We are issuing this AD to prevent a high 
temperature oxygen generator and mask from falling down and possibly 
resulting in an ignition source in the passenger compartment, injury to 
passengers, and reduced availability of supplemental oxygen.

DATES: This AD becomes effective December 2, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of December 2, 
2013.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
The NPRM published in the Federal Register on July 3, 2013 (78 FR 
40074). The NPRM proposed to correct an unsafe condition for the 
specified products.
    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
Airworthiness Directive 2012-0055, dated April 3, 2012 (referred to 
after this as the Mandatory Continuing Airworthiness Information, or 
``the MCAI''), to correct an unsafe condition for the specified 
products. The MCAI states:

    It has been determined that oxygen generators, installed on a 
specific batch of Type 1 (22 minute) passenger emergency oxygen 
container assemblies, may become detached by extreme pulling of the 
mask tube at the end of oxygen supply. Investigations revealed that 
such detachment can be caused by the increase in temperature towards 
the end of the generator operation, which may weaken the plastic 
housing in the attachment area of the bracket.
    This condition, if not corrected, could make the rivets slip 
through the plastic housing, causing a `hot' oxygen generator and 
mask to fall down, possibly resulting in injury to passengers.
    For the reasons described above, this [EASA] AD requires 
modification of the affected oxygen container assemblies. This 
[EASA] AD also prohibits the installation of the affected 
(unmodified) containers on any aeroplane as replacement parts.

The modification consists of adding a reinforcement plate at the rear 
outside of the container and adding two washers to the rivets at the 
inside of the container to prevent the generator from detaching. You 
may examine the MCAI in the AD docket on the Internet at <a href="http://www.regulations.gov/#!documentDetail">http://www.regulations.gov/#!documentDetail</a>;D=FAA-2013-0465-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (78 FR 40074, July 3, 
2013) or on the determination of the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting this AD as proposed-except for 
minor editorial changes. We have determined that these minor changes:
    <bullet> Are consistent with the intent that was proposed in the 
NPRM (78 FR 40074, July 3, 2013) for correcting the unsafe condition; 
and
    <bullet> Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 40074, July 3, 2013).

Costs of Compliance

    We estimate that this AD affects 4 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                Action                         Labor cost           Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
Modification..........................  2 work-hours x $85 per                $0            $170            $680
                                         hour = $170.
----------------------------------------------------------------------------------------------------------------


[[Page 64163]]

    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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 determined that 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 the DOT Regulatory Policies 
and Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska; and
    4. 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 AD and placed it in the AD docket.
