Airworthiness Directives; the Boeing Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain The Boeing Company Model 787-8 airplanes. This proposed 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 proposed AD would require replacing the low-
pressure oxygen hoses with non-conductive hoses in the crew oxygen 
system. We are proposing 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 compartment in the forward electronics equipment bay.

DATES: We must receive comments on this proposed AD by May 12, 2014.

ADDRESSES: You may send comments, using the procedures found in 14 CFR

Discussion

    We received a report indicating that, on a different Boeing 
airplane model, a fire originated near the first officer's area, which 
caused extensive damage to the flight deck. A Boeing investigation 
found that the low pressure flexible hoses in the pressurized 
flightcrew oxygen system can potentially be conductive because of the 
anti-kink metallic spring inside the hose. This condition, if not 
corrected, could result in inadvertent electrical current passing 
through an internal, anti-collapse spring of the low-pressure oxygen 
hose causing the low-pressure oxygen hose to melt or burn, leading to 
an oxygen-fed fire and/or smoke beneath the flight compartment in the 
forward electronics equipment bay.
    Some hoses on Model 787-8 airplanes are similar in design to those 
on the Boeing airplane model on which the fire occurred; therefore, 
Model 787-8 airplanes might be subject to the same unsafe condition.

Relevant Service Information

    We reviewed Boeing Alert Service Bulletin B787-81205-SB350001-00, 
Issue 001, dated August 22, 2013. For information on the procedures and 
compliance times, see this service information at http://www.regulations.gov by searching for Docket No. FAA-2014-0174.
    Boeing Alert Service Bulletin B787-81205-SB350001-00, Issue 001, 
dated August 22, 2013, refers to B/E Aerospace Service Bulletin 
4421086-35-001, Rev. 002, dated July 9, 2013, as an additional source 
of guidance for reworking the crew oxygen distribution manifold 
assembly.

FAA's Determination

    We are proposing 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.

Proposed AD Requirements

    This proposed AD would require replacing the low-pressure oxygen 
hoses with non-conductive hoses in the crew oxygen system, as specified 
in the service information described previously.

Typographical Error in Service Information

    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 the 
service information.

Costs of Compliance

    We estimate that this proposed AD affects 6 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                       Parts
             Action                  Labor cost         cost        Cost per product      Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Rework and replacement.........  Up to 2 work-hours     $1,798  Up to $1,968...........  Up to $11,808.
                                  x $85 per hour =
                                  $170.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, all of the costs of this proposed 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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    (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.
