We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This AD was prompted by a design review, which found that the burst pressure of the flexible hose used to vent oxygen from the high-pressure relief valve of the oxygen cylinder overboard is lower than the opening pressure of the high-pressure relief valve. This AD requires replacement of flexible relief hoses for the crew oxygen bottles with new metal design relief hoses. We are issuing this AD to prevent the accumulation of excess oxygen in an enclosed space, which could, if near a source of ignition, cause an uncontrolled oxygen-fed fire.

Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This AD 
was prompted by a design review, which found that the burst pressure of 
the flexible hose used to vent oxygen from the high-pressure relief 
valve of the oxygen cylinder overboard is lower than the opening 
pressure of the high-pressure relief valve. This AD requires 
replacement of flexible relief hoses for the crew oxygen bottles with 
new metal design relief hoses. We are issuing this AD to prevent the 
accumulation of excess oxygen in an enclosed space, which could, if 
near a source of ignition, cause an uncontrolled oxygen-fed fire.

DATES: This AD is effective September 8, 2016.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of September 8, 
2016.

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 Bombardier, Inc. 
Model BD-700-1A10 and BD-700-1A11 airplanes. The NPRM published in the 
Federal Register on April 12, 2016 (81 FR 21491) (``the NPRM''). The 
NPRM was prompted by a design review, which found that the burst 
pressure of the flexible hose used to vent oxygen from the high-
pressure relief valve of the oxygen cylinder overboard is lower than 
the opening pressure of the high-pressure relief valve. This pressure 
difference could cause the flexible hose to burst before it is able to 
vent excess oxygen overboard. The NPRM proposed to require replacement 
of flexible relief hoses for the crew oxygen bottles with new metal 
design relief hoses. We are issuing this AD to prevent the accumulation 
of excess oxygen in an enclosed space, which could, if near a source of 
ignition, cause an uncontrolled oxygen-fed fire.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2015-25, dated September 10, 2015 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for certain Bombardier, Inc. Model BD-700-
1A10 and BD-700-1A11 airplanes. The MCAI states:

    A design review found that the burst pressure of the flexible 
hose used to vent oxygen from the high-pressure relief valve of the 
oxygen cylinder overboard is lower than the opening pressure of the 
high-pressure relief valve. This could cause the flexible hose to 
burst before it is able to vent the excess oxygen overboard. If an 
ignition source is present, the accumulation of oxygen in an 
enclosed space may result in an uncontrolled oxygen-fed fire.
    This [Canadian] AD mandates the replacement of the oxygen 
[flexible] hose assembly with a new design oxygen [metal] hose 
assembly.

    You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
5459.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM or on the determination of 
the cost to the public. We reviewed the relevant data 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:
     Are consistent with the intent that was proposed in the 
NPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM.

Related Service Information Under 1 CFR Part 51

    Bombardier, Inc. has issued the following service information:
     Service Bulletin 700-35-013, Revision 01, dated July 22, 
2015.
     Service Bulletin 700-35-5001, Revision 01, dated July 22, 
2015;
     Service Bulletin 700-35-6001, Revision 01, dated July 22, 
2015; and
     Service Bulletin 700-1A11-35-012, Revision 01, dated July 
22, 2015.
    The service information describes procedures to replace the 
flexible oxygen hoses with metal hoses. 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.

Costs of Compliance

    We estimate that this AD affects 73 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                       hour = $255.
----------------------------------------------------------------------------------------------------------------

    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.

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 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 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.

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec.  39.13  [Amended]

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

2016-15-06 Bombardier, Inc.: Amendment 39-18597; Docket No. FAA-
2016-5459; Directorate Identifier 2015-NM-148-AD.

(a) Effective Date

    This AD is effective September 8, 2016.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bombardier, Inc. Model BD-700-1A10 and BD-
