We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) airplanes. This proposed 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 proposed AD would require replacing the oxygen hose assembly with a new, improved assembly. We are proposing 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), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 
440) airplanes. This proposed 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 proposed AD would require 
replacing the oxygen hose assembly with a new, improved assembly. We 
are proposing 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: We must receive comments on this proposed AD by May 28, 2015.

Discussion

    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 by searching for and locating Docket No. FAA-2015-
0823.

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; see ADDRESSES for ways to access this service 
information.

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 575 airplanes of U.S. 
registry.
    We also estimate that it would take about 2 work-hours per product 
to comply with the basic requirements of this proposed AD. Required 
parts would cost about $0 per product. The average labor rate is $85 
per work-hour. Based on these figures, we estimate the cost of this 
proposed AD on U.S. operators to be $97,750, or $170 per airplane.
    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

[[Page 19572]]

    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:

PART 39--AIRWORTHINESS DIRECTIVES

0
1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.


Sec.  39.13  [Amended]

0
2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Bombardier, Inc.: Docket No. FAA-2015-0823; Directorate Identifier 
2014-NM-211-AD.

(a) Comments Due Date

    We must receive comments by May 28, 2015.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bombardier, Inc. Model CL-600-2B19 (Regional 
Jet Series 100 & 440) airplanes, certificated in any category, 
serial numbers 7003 and subsequent.

(d) Subject

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

(e) Reason

    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. 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.

(f) Compliance

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

(g) Replacement

    Before the accumulation of 5,800 total flight hours or within 44 
months after the effective date of this AD, whichever occurs first, 
replace all oxygen hose assemblies having part number (P/N) 38026-4-
0280-000 with new, improved assemblies having P/N 601R44045-1, in 
accordance with the Accomplishment Instructions of Bombardier 
Service Bulletin 601R-35-018, dated May 21, 2013.

(h) Parts Installation Prohibition

    As of the effective date of this AD, no person may install an 
oxygen hose assembly, P/N 38026-4-0280-000, on any airplane.
