Federal Aviation Administration
14 CFR Part 39
[Docket No. FAA-2011-1089; Directorate Identifier 2011-NM-110-AD;
Amendment 39-17097; AD 2012-12-17]
RIN 2120-AA64
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-100-1A10 (Challenger 300) airplanes. This AD
was prompted by reports of deformation found at the neck of the
pressure regulator body on the oxygen cylinder and regulator assembly
(CRA). This AD requires an inspection to determine if a certain oxygen
CRA is installed and the replacement of affected oxygen CRAs. We are
issuing this AD to prevent elongation of the pressure regulator neck,
which could result in rupture of the oxygen cylinder, and, in the case
of cabin depressurization, oxygen not being available when required.
DATES: This AD becomes effective July 30, 2012.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of July 30,
2012.
ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov or in person at the U.S. Department of
Transportation, Docket Operations, M-30, West Building Ground Floor,
Room W12-140, 1200 New Jersey Avenue SE., Washington, DC.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a supplemental notice of proposed rulemaking (SNPRM) to
amend 14 CFR part 39 to include an AD that would apply to the specified
products. That SNPRM was published in the Federal Register on February
8, 2012 (77 FR 6525). The original NPRM (76 FR 64857, October 19, 2011)
proposed to require an inspection to determine if a certain oxygen
cylinder and regulator assembly (CRA) is installed and the replacement
of affected oxygen CRAs. The SNPRM proposed to change the compliance
time in paragraph (g) of the SNPRM.
You may obtain further information by examining the MCAI in the AD
docket.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the SNPRM (77 FR 6525, February 8,
2012), or on the determination of the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed.
Costs of Compliance
We estimate that this AD will affect 79 products of U.S. registry.
We also estimate that it will take about 3 work-hours per product to
comply with the basic requirements of this AD. The average labor rate
is $85 per work-hour. Required parts will cost about $0 per product.
Where the service information lists required parts costs that are
covered under warranty, we have assumed that there will be no charge
for these parts. As we do not control warranty coverage for affected
parties, some parties may incur costs higher than estimated here. Based
on these figures, we estimate the cost of this AD to the U.S. operators
to be $29,145, or $255 per product.
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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket.
Examining the AD Docket
You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the SNPRM (77 FR 6525, February 8,
2012), the regulatory evaluation, any comments received, and other
information. The street address for the Docket Operations office
(telephone (800) 647-5527) is in the ADDRESSES section. Comments will
be available in the AD docket shortly after receipt.

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

2. The FAA amends Sec. 39.13 by adding the following new AD:
2012-12-17 Bombardier, Inc.: Amendment 39-17097. Docket No. FAA-
2011-1089; Directorate Identifier 2011-NM-110-AD.

(d) Subject
Air Transport Association (ATA) of America Code 35: Oxygen.
(e) Reason
This AD was prompted by reports of deformation found at the neck
of the pressure regulator body on the oxygen cylinder and regulator
assembly (CRA). We are issuing this AD to prevent elongation of the
pressure regulator neck, which could result in rupture of the oxygen
cylinder, and in the case of cabin depressurization, oxygen not
being available when required.
(f) Compliance
You are responsible for having the actions required by this AD
performed within the compliance times specified, unless the actions
have already been done.
(g) Actions
For airplanes having S/Ns 20003 through 20291 inclusive: Within
750 flight hours, or within 6 months after the effective date of
this AD, whichever occurs first, inspect oxygen pressure regulators
having part number (P/N) 806370-06 or 806370-14, to determine the
serial number, in accordance with paragraph 2.B.(2) of the
Accomplishment Instructions of Bombardier Service Bulletin 100-35-
05, Revision 02, dated January 31, 2011.
(1) If the serial number of the oxygen pressure regulator is
listed in table 2 of the Accomplishment Instructions of Bombardier
Service Bulletin 100-35-05, Revision 02, dated January 31, 2011,
replace the affected oxygen CRA, in accordance with paragraph 2.C.
of the Accomplishment Instructions of Bombardier Service Bulletin
100-35-05, Revision 02, dated January 31, 2011.
(2) If the serial number of the oxygen pressure regulator is not
listed in table 2 of the Accomplishment Instructions of Bombardier
Service Bulletin 100-35-05, Revision 02, dated January 31, 2011, no
further action is required by this paragraph.
(h) Parts Installation
For all airplanes: As of the effective date of this AD, no
person may install an oxygen pressure regulator (P/N 806370-06 or
806370-14) having any serial number listed in table 2 of the
Accomplishment Instructions of Bombardier Service Bulletin 100-35-
05, Revision 02, dated January 31, 2011, on any airplane, unless a
suffix ``-A'' is beside the serial number.

reference this AD.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
