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 <a href="http://www.regulations.gov">http://www.regulations.gov</a> 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 <a href="http://www.regulations.gov">http://www.regulations.gov</a>, 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.
