14 CFR Part 39

[Docket No. FAA-2017-0333; Directorate Identifier 2017-NM-005-AD; 
Amendment 39-18974; AD 2017-15-14]

Airworthiness Directives; Bombardier, Inc. (Type Certificate 
Previously Held by Canadair Limited) 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 CL-215-6B11 (CL-415 Variant) airplanes. This AD 
was prompted by a report indicating that an oxygen bottle was found 
loose while the clamp strap was in the locked position. This AD 
requires modification of the clamp strap and installation of additional 
shims, as applicable, to the flight crew's oxygen bottles' retaining 
structures. We are issuing this AD to address the unsafe condition on 
these products.

DATES: This AD is effective September 5, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of September 5, 
2017.

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 CL-215-6B11 (CL-415 Variant) airplanes. The NPRM published in the

[[Page 35637]]

Federal Register on May 9, 2017 (82 FR 21482).
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2016-33, dated October 
12, 2016 (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Bombardier, Inc., Model CL-215-6B11 (CL-415 
Variant) airplanes. The MCAI states:

    During the implementation of Service Bulletin (SB) 215-4051, the 
oxygen bottle was found loose while the clamp strap was in the 
locked position. This was determined to be caused by the quick 
release latch assembly not achieving the proper clamping pressure.
    The release of the oxygen bottle due to improper clamping 
pressure may result in a loose mass cockpit hazard or an oxygen rich 
environment leading to a possible fire hazard.
    In order to mitigate the unsafe condition, SB 215-4457 was 
issued to modify the clamp strap and install additional shims to add 
strength to the attaching structure for all affected aeroplanes.

    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-2017-
0333.

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.

Conclusion

    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 Service Bulletin 215-4457, Revision 3, 
dated May 8, 2013. The service information describes procedures for 
installing shims, and, for certain airplanes, modifying the straps of 
the latch assembly, on the flight crew's oxygen bottles' retaining 
structure. 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 24 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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.

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

2017-15-14 Bombardier, Inc. (Type Certificate Previously Held by 
Canadair Limited): Amendment 39-18974; Docket No. FAA-2017-0333;

    This AD is effective September 5, 2017.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bombardier, Inc. (Type Certificate previously 
held by Canadair Limited) Model CL-215-6B11 (CL-415 Variant) 
airplanes, certificated in any category, having serial numbers 2001, 
2002, 2005 through 2007 inclusive, 2010, 2012 through 2017
