Airworthiness Directives; Bombardier, Inc., Airplanes

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

ACTION: Final rule.

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

SUMMARY: The FAA is adopting a new airworthiness directive (AD) for 
certain Bombardier, Inc., Model CL-600-2B19 (Regional Jet Series 100 & 
440); CL-600-2C10 (Regional Jet Series 700, 701 & 702); CL-600-2D15 
(Regional Jet Series 705); CL-600-2D24 (Regional Jet Series 900); and

oxygen masks. This AD requires repacking the flight attendant and 
lavatory oxygen box assemblies as applicable, replacing the placards, 
and re-identifying the assemblies. The FAA is issuing this AD to 
address the unsafe condition on these products.

SUPPLEMENTARY INFORMATION: 

Discussion

    The FAA 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-600-2B19 (Regional Jet Series 100 & 440); CL-600-2C10 
(Regional Jet Series 700, 701 & 702); CL-600-2D15 (Regional Jet Series 
705); CL-600-2D24 (Regional Jet Series 900); and CL-600-2E25 (Regional 
Jet Series 1000) airplanes. The NPRM published in the Federal Register 
on June 11, 2019 (84 FR 27042). The NPRM was prompted by reports of 
incorrect deployment of forward and aft flight attendant oxygen masks. 
The NPRM proposed to require repacking the flight attendant and 
lavatory oxygen box assemblies as applicable, replacing the placards, 
and re-identifying the assemblies.
    The FAA is issuing this AD to address incorrect packing of the 
flight attendant and lavatory oxygen box assemblies, which could result 
in incorrectly deployed oxygen masks, and cause occupant distress and 
delayed access to oxygen supply during a high altitude emergency.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2018-03, dated January 
19, 2018 (referred to after this as the Mandatory Continuing 
Airworthiness Information, or ``the MCAI''), to correct an unsafe 
condition for certain Model CL-600-2B19 (Regional Jet Series 100 & 
440); CL-600-2C10 (Regional Jet Series 700, 701 & 702); CL-600-2D15 
(Regional Jet Series 705); CL-600-2D24 (Regional Jet Series 900); and 
CL-600-2E25 (Regional Jet Series 1000) airplanes. The MCAI states:

    After an in-service cabin oxygen masks deployment on a CL-600-
2D24 aeroplane,

[[Page 48051]]

the crew noted that the forward and aft flight attendant oxygen 
masks did not deploy correctly. The oxygen hoses were tangled with 
the pull lanyard and cordage from the oxygen box assemblies. 
Investigation found the same condition on other aeroplanes. The 
similarly designed lavatory oxygen box assembly is also affected. It 
was determined that packing instructions for these oxygen box 
assemblies were incorrect. If not corrected, inappropriately packed 
oxygen box assemblies resulting in incorrectly deployed oxygen masks 
can cause occupant distress and delayed access to oxygen supply 
during a high altitude emergency.
    This [Canadian] AD mandates the repacking of the forward flight 
attendant, aft flight attendant, and lavatory oxygen box assemblies 
[as applicable] and the installation of a revised packaging placard.

    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-2019-
0327.

Comments

    The FAA gave the public the opportunity to participate in 
developing this final rule. The FAA received no comments on the NPRM or 
on the determination of the cost to the public.

Conclusion

    The FAA reviewed the relevant data and determined that air safety 
and the public interest require adopting this final rule as proposed, 
except for minor editorial changes. The FAA has determined that these 
minor changes:
     Are consistent with the intent that was proposed in the 
NPRM for addressing 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 has issued the following service information:
     Service Bulletin 601R-35-021, dated October 30, 2017, 
which describes procedures for repacking the lavatory oxygen box 
assembly, replacing the placards, and re-identifying the assembly.
     Service Bulletin 670BA-35-015, dated October 30, 2017, 
which describes procedures for repacking the flight attendant and 
lavatory oxygen box assemblies, replacing the placards, and re-
identifying the assemblies.
    These documents are distinct since they apply to different airplane 
models. 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

    The FAA estimates that this AD affects 539 airplanes of U.S. 
registry. The FAA estimates the following costs to comply with this AD:

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
5 work-hours x $85 per hour = $425...........................            $100             $525         $282,975
----------------------------------------------------------------------------------------------------------------

    According to the manufacturer, some or all of the costs of this AD 
may be covered under warranty, thereby reducing the cost impact on 
affected individuals. The FAA does not control warranty coverage for 
affected individuals. As a result, the FAA has included all known costs 
in the 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.
    The FAA is 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 and 
associated appliances to the Director of the System Oversight Division.

Regulatory Findings

    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) Will not affect intrastate aviation in Alaska, and
    (3) 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.
