Airworthiness Directives; The Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
The Boeing Company Model 787-8 airplanes. This AD 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. 
This AD requires 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.

DATES: This AD is effective December 31, 2014.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of December 31, 
2014.

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.

    Paragraph III.A., ``Verification,'' of B/E Aerospace Service 
Bulletin 4421086-35-001, Rev. 002, dated July 9, 2013, has a 
typographical error. The last sentence in that paragraph states, 
``If the decal shows PN 4421086-101, continue with the retrofit 
steps in paragraph II.B.'' The sentence should refer to paragraph 
III.B. of B/E Aerospace Service Bulletin 4421086-35-001, Rev. 002, 
dated July 9, 2013.
