14 CFR Part 39

[Docket No. FAA-2013-0864; Directorate Identifier 2013-NM-108-AD]
RIN 2120-AA64


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 777F series airplanes. This proposed 
AD was prompted by a report of a fire that originated near the first 
officer's seat and caused extensive damage to the flight deck. This 
proposed AD would require replacing the low-pressure oxygen hoses with 
non-conductive low-pressure oxygen hoses in the stowage box and 
supernumerary ceiling area. We are proposing this AD to prevent 
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 and lead to an oxygen-fed fire on 
the flight deck.

DATES: We must receive comments on this proposed AD by December 9, 
2013.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    We have received a report of a fire that originated near the first 
officer's seat and caused extensive damage to the flight deck. 
Electrical current passing through an internal, anti-collapse spring of 
the low-pressure oxygen hose can cause the low-pressure oxygen hose to 
melt or burn and lead to an oxygen-fed fire on the flight deck.

 Relevant Service Information

    We reviewed Boeing Alert Service Bulletin 777-35A0029, Revision 1, 
dated April 29, 2013. For information on the procedures, see this 
service information at http://www.regulations.gov by searching for 
Docket No. FAA-2013-0864.

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 accomplishing the actions specified 
in the service information identified previously.

Costs of Compliance

    We estimate that this proposed AD affects 18 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
              Action                        Labor cost            Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
Replace oxygen hoses..............  7 work-hours x $85 per             $1,450           $2,045          $36,810
                                     hour = $595.
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some 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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

The Boeing Company: Docket No. FAA-2013-0864; Directorate Identifier 
2013-NM-108-AD.

(a) Comments Due Date

    We must receive comments by December 9, 2013.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to The Boeing Company Model 777F series

2013.

(d) Subject

    Joint Aircraft System Component (JASC)/Air Transport Association 
(ATA) of America Code 35, Oxygen.

(e) Unsafe Condition

    This AD was prompted by a report of a fire that originated near 
the first officer's seat and caused extensive damage to the flight 
deck. We are issuing this AD to prevent 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 and lead to an oxygen-fed fire on the flight deck.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Oxygen Hose Replacement

    Within 36 months after the effective date of this AD: Replace 
the low-pressure oxygen hoses in the stowage box and supernumerary 
ceiling area with new non-conductive low-pressure oxygen hoses, in 
accordance with the Accomplishment Instructions of Boeing Alert 
Service Bulletin 777-35A0029, Revision 1, dated April 29, 2013.

(h) Parts Installation Prohibition

    As of the effective date of this AD, no person may install a 
low-pressure oxygen hose, part number (P/N) 57034-08A050140,

[[Page 63132]]

P/N 57034-08A050215, or P/N 57034-09A050270, on any airplane.

(i) Credit for Previous Actions

    This paragraph provides credit for the actions specified in 
paragraph (g) of this AD, if those actions were performed before the 
effective date of this AD using Boeing Alert Service Bulletin 777-
35A0029, dated June 6, 2012, provided that the low-pressure oxygen 
hoses described in Boeing Alert Service Bulletin 777-35A0029, 
Revision 1, dated April 29, 2013, were replaced with new non-
conductive low-pressure oxygen hoses. Boeing Alert Service Bulletin 
777-35A0029, dated June 6, 2012, is not incorporated by reference in 
this AD.

(j) Alternative Methods of Compliance (AMOCs)

    (1) The Manager, Seattle Aircraft Certification Office (ACO), 
FAA, has the authority to approve AMOCs for this AD, if requested 
using the procedures found in 14 CFR 39.19. In accordance with 14 
CFR 39.19, send your request to your principal inspector or local 
Flight Standards District Office, as appropriate. If sending 
information directly to the manager of the ACO, send it to the 
attention of the person identified in paragraph (k) of this AD. 
Information may be emailed to 9-ANM-Seattle-ACO-AMOC-Requests@faa.gov.
    (2) Before using any approved AMOC, notify your appropriate 
principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office.
    (3) An AMOC that provides an acceptable level of safety may be 
used for any repair required by this AD if it is approved by the 
Boeing Commercial Airplanes ODA that has been authorized by the 
Manager, Seattle ACO, to make those findings. For a repair method to 
be approved, the repair must meet the certification basis of the 
airplane, and the approval must specifically refer to this AD.
