We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This AD was prompted by results of a design review indicating that the burst pressure of the flexible hose, used to vent oxygen from the high-pressure relief valve of the oxygen cylinder overboard, was lower than the opening pressure of the high-pressure relief valve, which could cause the flexible hose to burst before it can vent the excess oxygen overboard. This AD requires replacing the oxygen hose assembly with a new, improved assembly. We are issuing this AD to prevent the accumulation of oxygen in an enclosed space, which could result in an uncontrolled oxygen-fed fire if an ignition source is nearby.

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-600-2B19 (Regional Jet Series 100 & 440) 
airplanes. This AD was prompted by results of a design review 
indicating that the burst pressure of the flexible hose, used to vent 
oxygen from the high-pressure relief valve of the oxygen cylinder 
overboard, was lower than the opening pressure of the high-pressure 
relief valve, which could cause the flexible hose to burst before it 
can vent the excess oxygen overboard. This AD requires replacing the 
oxygen hose assembly with a new, improved assembly. We are issuing this 
AD to prevent the accumulation of oxygen in an enclosed space, which 
could result in an uncontrolled oxygen-fed fire if an ignition source 
is nearby.

DATES: This AD becomes effective October 2, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of October 2, 
2015.

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-600-2B19 (Regional Jet Series 100 & 440) airplanes. The NPRM 
published in the Federal Register on April 13, 2015 (80 FR 19570).
    Transport Canada Civil Aviation (TCCA), which is the airworthiness 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-36, dated October 17, 2014 (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-
2B19 (Regional Jet Series 100 & 440) airplanes. The MCAI states:

    Design review found that the burst pressure of the flexible 
hose, used to vent oxygen from the high-pressure relief valve of the 
oxygen cylinder overboard, is lower than the opening pressure of the 
high-pressure relief valve. This could cause the flexible hose to 
burst before it is able to vent the excess oxygen overboard. If an 
ignition source is present, the accumulation of oxygen in an 
enclosed space may result in an uncontrolled oxygen-fed fire.
    This [Canadian] AD mandates the replacement of the oxygen hose 
assembly with a new design oxygen hose assembly.

You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2015-0823-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. The following presents the comments received on the NPRM (80 
FR 19570, April 13, 2015) and the FAA's response to each comment.

Request To Extend the Compliance Time

    Mesa Airlines asked that the compliance time specified in paragraph 
(g) of the NPRM (80 FR 19570, April 13, 2015) be changed. Mesa Airlines 
stated that the current compliance time would immediately ground 
airplanes on the effective date of the AD. Mesa Airlines asked that we 
change the compliance time to ``Within 6,000 flight hours, or within 44 
months after the effective date of this AD, whichever occurs first.'' 
Mesa Airlines added that this would allow for scheduling with heavy 
maintenance inspection and parts procurement.
    We partially agree with the request. We have changed the compliance 
time in paragraph (g) of this AD to ``Within 5,800 flight hours or 44 
months after the effective date of this AD, whichever occurs first.'' 
This change matches the compliance time in the MCAI, and will allow 
operators to remain in compliance.
    We do not agree that the compliance time should be extended to 
``Within 6,000 flight hours, or within 44 months after the effective 
date of this AD, whichever occurs first''. After considering all the 
available information, we have determined that the compliance time 
represents an appropriate interval of time in which the required 
actions can be performed in a timely manner within the affected fleet, 
while still maintaining an adequate level of safety. In developing an 
appropriate compliance time, we considered the safety implications, 
parts availability, and normal maintenance schedules for timely 
accomplishment of the replacement. However, if additional data are 
presented that would justify a longer compliance time, we may consider 
further rulemaking on this issue. We have not changed the AD in this 
regard.

Request To Refer To Revised Service Information

    Richard Rupslauskas asked that we include Bombardier Service 
Bulletin 601R-35-018, Revision A, in the NPRM (80 FR 19570, April 13, 
2015), and give credit for Bombardier Service Bulletin 601R-35-018, 
dated May 21, 2013. The commenter stated that Revision A should be 
distributed very soon, and added that no additional work will be 
required on aircraft that have had the modification incorporated using 
the original issue of the service information. The commenter added that 
the NPRM should recognize that either the original or Revision A of the 
service information is acceptable as a method of compliance.
    We do not agree to reference Bombardier Service Bulletin 601R-35-
018, Revision A, because that revision has not yet been issued. 
However, after Revision A is issued, affected operators may request 
approval to use that revision of the referenced service bulletin as an 
alternative method of compliance, under the provisions of paragraph 
(i)(1) of this AD.

Request To Include Parts Cost

    Richard Rupslauskas stated that the parts cost is $835 per 
airplane, and added that since 575 airplanes are affected, the total 
cost for parts is $480,125.
    We infer that the commenter wants the parts cost included in the 
``Costs of Compliance'' section of this AD. We agree to include the 
parts cost of $835 in that section. We have changed this AD 
accordingly.

Conclusion

    We reviewed the relevant data, considered the comments received, 
and determined that air safety and the public interest require adopting 
this AD with the changes described previously and minor editorial 
changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
NPRM (80 FR 19570, April 13, 2015) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (80 FR 19570, April 13, 2015).
    We also determined that these changes will not increase the 
economic burden on any operator or increase the scope of this AD.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued Service Bulletin 601R-35-018, dated May 21, 
2013. The service information describes procedures for replacing the 
oxygen hose assembly with a new, improved assembly. The actions 
described in this service information are intended to correct the 
unsafe condition identified in the MCAI. This service information is 
reasonably available because the interested parties have access to it

[[Page 52181]]

through their normal course of business or by the means identified in 
the ADDRESSES section of this AD.

Costs of Compliance

    We estimate that this AD affects 575 airplanes of U.S. registry.
    We also estimate that it takes about 2 work-hours per product to 
comply with the basic requirements of this AD. Required parts will cost 
about $835 per product. The average labor rate is $85 per work-hour. 
Based on these figures, we estimate the cost of this AD on U.S. 
operators to be $577,875, or $1,005 per airplane.
    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.

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.
