ACTION: Final rule.
AGENCY:
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 highpressure 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 highpressure 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:
PO 00000
Frm 00027
Fmt 4700
Sfmt 4700
51323
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 https://
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,

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.

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 https://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:
[[Page 51324]]
Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.
Action Labor cost Parts cost product operators
----------------------------------------------------------------------------------------------------------------
Modification........................ 3 work-hours x $85 per $14,483 $14,738 $1,075,874
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.

Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
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-
700-1A11 airplanes, certificated in any category, having serial
numbers (S/Ns) 9002 through 9704 inclusive, and 9998.
(d) Subject
Air Transport Association (ATA) of America Code 35, Oxygen.
(e) Reason
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
pressure difference could cause the flexible hose to burst before it
is able to vent excess oxygen overboard. 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.
(f) Compliance
Comply with this AD within the compliance times specified,
unless already done.
(g) Modification
Within 2,500 flight hours or 42 months, whichever occurs first,
after the effective date of this AD, incorporate Bombardier Modsum
