[Docket No. FAA-2017-0477; Directorate Identifier 2016-NM-112-AD]
RIN 2120-AA64
Airworthiness Directives; Bombardier, Inc., Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD)
for
certain Bombardier, Inc., Model CL-600-2B16 (CL-601-3A, CL-601-3R, and
CL-604 Variants) airplanes. This proposed AD was prompted by a report
indicating that the lanyard length of the passenger drop down oxygen
masks is too long. This proposed AD would require replacing the
existing oxygen mask lanyards with lanyards of the correct length. We
are proposing this AD to address the unsafe condition on these
products.
DATES: We must receive comments on this proposed AD by July 6,
2017.
ADDRESSES: You may send comments, using the procedures found in
14 CFR
11.43 and 11.45, by any of the following methods:

Discussion
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2016-15, dated June 1, 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-600-2B16 (CL-
601-3A, CL-601-3R, and CL-604 Variants) airplanes. The MCAI states:
Bombardier (BA) has determined that the lanyard length of the
passenger drop down oxygen masks is too long and may cause the
safety pin tethered to the opposite end of the lanyard to remain
engaged in the oxygen flow mechanism when the mask is pulled to the
passenger's face. In an emergency situation where oxygen is
required, it is possible that certain passengers may not receive
oxygen supply due to the increased length of the lanyard.
[Bombardier] has issued service bulletin (SB) 605-35-003 to
replace the existing lanyards in the passenger oxygen box assemblies
with lanyards of the correct length. Incorporation of this
[Bombardier service bulletin] will restore the proper oxygen flow
functionality to the passenger oxygen masks in the event of an
emergency.
This [Canadian] AD mandates the incorporation of [Bombardier
service bulletin] 605-35-003.
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-2017-0477.
Related Service Information Under 1 CFR Part 51
Bombardier, Inc., issued Service Bulletin 605-35-003, Revision 02,
dated April 18, 2016. This service information describes procedures for
replacing the existing oxygen mask lanyards with lanyards of the
correct length. 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.
FAA's Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
Costs of Compliance
We estimate that this proposed AD affects 120 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:
Estimated Costs
|
Action
|
Labor cost
|
Parts cost
|
Cost per
product
|
Cost on
U.S. operators
|
| Replacement |
4 work-hours x $85 per hour =
$340 |
Not available |
$340
|
$40,800
|
According to the manufacturer, some
of the costs of this proposed
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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
regulation:
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.

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

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