14 CFR Part 39

[Docket No. FAA-2017-0477; Product Identifier 2016-NM-112-AD; Amendment 
39-18990; AD 2017-16-13]
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 CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 
Variants) airplanes. This AD was prompted by a report indicating that 
the lanyard length of the passenger drop down oxygen masks is too long. 
This AD requires replacing the existing oxygen mask lanyards with 
lanyards of the correct length. We are issuing this AD to address the 
unsafe condition on these products.

DATES: This AD is effective September 25, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of September 
25, 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-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 Variants) 
airplanes. The NPRM published in the Federal Register on May 22, 2017 
(82 FR 23156) (``the NPRM''). The NPRM was prompted by a report 
indicating that the lanyard length of the passenger drop down oxygen 
masks is too long. The NPRM proposed to require replacing the existing 
oxygen mask lanyards with lanyards of the correct length. We are 
issuing this AD to prevent improper oxygen flow functionality to the 
passenger oxygen masks in the event of an emergency.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2016-15, dated May 18, 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.
    BA 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 BA SB 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] SB 
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.

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 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.

Costs of Compliance

    We estimate that this AD affects 120 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

----------------------------------------------------------------------------------------------------------------

[[Page 39519]]

    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.
    This AD is issued in accordance with authority delegated by the 
Executive Director, Aircraft Certification Service, as authorized by 
FAA Order 8000.51C. In accordance with that order, issuance of ADs is 
normally a function of the Compliance and Airworthiness Division, but 
during this transition period, the Executive Director has delegated the 
authority to issue ADs applicable to transport category airplanes to 
the Director of the System Oversight Division.

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.

(d) Subject

    Air Transport Association (ATA) of America Code 35, Oxygen.

(e) Reason

    This AD was prompted by a report indicating that the lanyard 
length of the passenger drop down oxygen masks is too long. The 
length of the oxygen mask lanyard might 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. We are issuing this AD to prevent improper oxygen flow 
functionality to the passenger oxygen masks in the event of an 
emergency.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Replacement of Oxygen Mask Lanyards

    Within 2,400 flight hours or 60 months, whichever occurs first 
after the effective date of this AD, replace the existing lanyards 
in the passenger oxygen box assemblies with lanyards of the correct 
length, in accordance with the Accomplishment Instructions of 
Bombardier Service Bulletin 605-35-003, Revision 02, dated April 18, 
2016.

(h) Credit for Previous Actions

    This paragraph provides credit for actions required by paragraph 
(g) of this AD, if those actions were performed before the effective 
date of this AD using Bombardier Service Bulletin 605-35-003, dated 
January 28, 2016; or Bombardier Service Bulletin 605-35-003, 
Revision 01, dated February 10, 2016.

AMOC, notify your appropriate principal inspector, or lacking a 
principal inspector, the manager of the local flight standards 
district office/certificate holding district office.
    (2) Contacting the Manufacturer: For any requirement in this AD 
to obtain corrective actions from a manufacturer, the action must be 
accomplished using a method approved by the Manager, New York ACO, 
FAA; or Transport Canada Civil Aviation (TCCA); or Bombardier, 
Inc.'s TCCA Design Approval Organization (DAO). If approved by the 
DAO, the approval must include the DAO-authorized signature.
