SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to certain The Boeing Company
Model 787-8 airplanes. The NPRM published in the Federal Register on
March 28, 2014 (79 FR 17457). The NPRM was prompted by a report
indicating that, on a different Boeing airplane model, there was an
oxygen-fed fire, which caused extensive damage to the flight deck. The
NPRM proposed to require replacing the low-pressure oxygen hoses with
non-conductive hoses in the crew oxygen system. We are issuing this AD
to prevent inadvertent electrical current from passing through an
internal, anti-collapse spring of the low pressure oxygen hose, which
can cause the low-pressure oxygen hose to melt or burn, leading to an
oxygen-fed fire and/or smoke beneath the flight deck in the forward
electronics equipment bay.
Comments
We gave the public the opportunity to participate in developing
this AD. The following presents the comments received on the NPRM (79
FR 17457, March 28, 2014) and the FAA's response to each comment.
Boeing, United Airlines, and John Johnson stated that they support
the NPRM (79 FR 17457, March 28, 2014).
Request To Shorten Compliance Time
The Air Line Pilots Association (ALPA) stated that it supports the
intent of the NPRM (79 FR 17457, March 28, 2014) but that the 60-month
compliance
[[Page 70446]]
time is excessive. ALPA recommended that the compliance time be
shortened. ALPA did not provide justification for its request, or
propose what the shorter compliance time should be.
We do not agree that the compliance time for this final rule should
be shortened. In developing the compliance time we considered the
implications, parts availability, and normal maintenance schedules for
timely accomplishment of the replacement of the oxygen hoses. Further,
the compliance time is in keeping with the manufacturers' recommended
compliance time. Operators are always permitted to accomplish the
requirements of an AD earlier than the specified compliance time. If
additional data are presented that would justify reducing the
compliance time we may consider further rulemaking on this issue. We
have not changed this final rule in this regard.
Conclusion
We reviewed the relevant data, considered the comments received,
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 (79 FR 17457, March 28, 2014) for correcting the unsafe condition;
and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM (79 FR 17457, March 28, 2014).
Costs of Compliance
We estimate that this AD affects 6 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost on U.S.
Action Labor cost Parts cost Cost per product operators
----------------------------------------------------------------------------------------------------------------
Rework and replacement........ Up to 2 work- $1,798 Up to $1,968......... Up to $11,808.
hours x $85 per
hour = $170.
----------------------------------------------------------------------------------------------------------------
According to the manufacturer, all 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
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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
