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

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 Start Printed 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.
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 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:
|Action||Labor cost||Parts cost||Cost per product||Cost on U.S. operators|
|Modification and installation||16 work-hours × $85 per hour = $1,360||$2,250||$3,610||$86,640|
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.
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.Start List of Subjects
