Federal Aviation Administration

14 CFR Part 39

[Docket No. FAA-2016-5033; Directorate Identifier 2015-NM-118-AD; 
Amendment 39-18450; AD 2016-07-05]
RIN 2120-AA64


Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
The Boeing Company Model 747-8 series airplanes. This AD requires an 
inspection to determine if all oxygen components in the passenger 
oxygen system are installed, installation of new o-rings, and 
corrective actions if necessary. This AD was prompted by a report that 
oxygen tube couplings in the passenger oxygen system could be missing 
or incorrectly installed. We are issuing this AD to detect and correct 
oxygen leaks from oxygen tube couplings in the passenger oxygen system, 
which could result in depletion of emergency oxygen at a faster rate 
than expected, reduce the passengers' and crews' protection from 
hypoxia at elevated cabin altitudes, and increase the risk of a fire.

DATES: This AD is effective April 15, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of April 15, 
2016.
    We must receive comments on this AD by May 16, 2016.

SUPPLEMENTARY INFORMATION: 

Discussion

    We have determined that some Model 747-8 series airplanes could 
have oxygen components missing or incorrectly installed at oxygen tube 
couplings attached to the outboard stowage bin support assemblies. The 
manufacturer believes that these airplanes were delivered with the 
correct configuration of oxygen components. However, because of an 
error in an engineering drawing and related parts list, which omitted 
part number call-outs for some oxygen components, we want to be certain

[[Page 18465]]

installations are correct and prevent incorrect installation during 
subsequent rework of the oxygen tubing components. This condition, if 
not corrected, could result in oxygen leaks from oxygen tube couplings 
in the passenger oxygen system, which could result in depletion of 
emergency oxygen at a faster rate than expected, reduce the passengers' 
and crews' protection from hypoxia at elevated cabin altitudes, and 
increase the risk of a fire.

Related Service Information Under 1 CFR Part 51

    We reviewed Boeing Special Attention Service Bulletin 747-35-2132, 
dated June 8, 2015. The service information describes procedures for 
inspection of passenger oxygen coupler assemblies for missing oxygen 
components, installation of o-rings, and corrective actions. This 
service information is reasonably available because the interested 
parties have access to it through their normal course of business or by 
the means identified in the ADDRESSES section.

FAA's Determination

    We are issuing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of the same type design.

AD Requirements

    This AD requires accomplishing the actions identified in the 
service information identified previously. For information on the 
procedures and compliance times, see this service information at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
5033.
    The phrase ``corrective actions'' is used in this AD. ``Corrective 
actions'' are actions that correct or address any condition found. 
Corrective actions in an AD could include, for example, repairs.
    This AD also requires sending the inspection results to the 
Manager, Seattle Aircraft Certification Office, FAA.

FAA's Justification and Determination of the Effective Date

    There are no products of this type currently registered in the 
United States. However, this rule is necessary to ensure that the 
described unsafe condition is addressed if any of these products are 
placed on the U.S. Register in the future. Therefore, we find that 
notice and opportunity for prior public comment are unnecessary and 
that good cause exists for making this amendment effective in less than 
30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety and was not preceded by notice and an opportunity for public 
comment. However, we invite you to send any written data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2016-5033; Directorate 
Identifier 2015-NM-118-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD because of 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 0 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
----------------------------------------------------------------------------------------------------------------
Inspection...........................  8 work-hours x $85 per                 $0            $680              $0
                                        hour = $680.
Reporting............................  1 work-hour x $85 per                   0              85               0
                                        hour = $85.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary corrective 
actions that will be required based on the results of the inspection. 
We have no way of determining the number of aircraft that might need 
these repairs:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per
                    Action                                Labor cost               Parts cost        product
----------------------------------------------------------------------------------------------------------------
Corrective Action............................  8 work-hours x $85 per hour =            $6,888           $7,568
                                                $680.
----------------------------------------------------------------------------------------------------------------

    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.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting associated with 
this AD is mandatory. Comments concerning the accuracy of this burden 
and suggestions for reducing the burden should be directed to the FAA 
at 800 Independence Ave. SW., Washington, DC 20591, ATTN: Information 
Collection Clearance Officer, AES-200.

Authority for This Rulemaking

    Title 49 of the United States Code specifies the FAA's authority to 
issue

[[Page 18466]]

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),
    (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.
