Airworthiness Directives; Bombardier, Inc. Airplanes

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

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Bombardier, Inc. Model CL-600-2B19 (Regional Jet Series 100 & 440) 
airplanes, CL-600-2C10 (Regional Jet Series 700, 701 & 702) airplanes, 
CL-600-2D15 (Regional Jet Series 705) airplanes, CL-600-2D24 (Regional 
Jet Series 900) airplanes, and CL-600-2E25 (Regional Jet Series 1000) 
airplanes. This AD requires repetitive detailed inspections of the cage 
assembly, window louver panel assemblies (WLPAs), and blowout panels 
(BOPs), and corrective action if necessary. This AD was prompted by 
reports of several

[[Page 74674]]

cases of damaged or detached decompression WLPAs and BOPs. We are 
issuing this AD to detect and correct damaged and detached WLPAs and 
BOPs. A detached WLPA or BOP could delay smoke detection in the cargo 
compartment, and in the event of a cargo compartment fire, this could 
lead to an uncontrolled cargo compartment fire.

DATES: This AD becomes effective December 15, 2015.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of December 15, 
2015.

SUPPLEMENTARY INFORMATION: 

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2015-28, dated October 21, 2015 (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, CL-600-2C10 (Regional 
Jet Series 700, 701 & 702) airplanes, CL-600-2D15 (Regional Jet Series 
705) airplanes, CL-600-2D24 (Regional Jet Series 900) airplanes, and 
CL-600-2E25 (Regional Jet Series 1000) airplanes. The MCAI states:

    Several cases of damaged decompression window louver panel 
assemblies (WLPAs) have been reported in-service. Subsequent review 
of in-service data also showed multiple reports of detached blowout 
panels (BOPs). Damaged or detached WLPAs or BOPs create openings in 
the cargo compartment.
    The presence of unintended openings on the WLPAs and BOPs could 
delay smoke detection in the cargo compartment. In addition, the 
cargo compartment may not be able to maintain Halon concentration 
required for fire suppression. In the event of a cargo compartment 
fire, this condition could lead to an uncontrolled cargo compartment 
fire.
    This [Canadian] AD mandates the repetitive inspection of the 
affected WLPAs and BOPs.

    Required actions include repetitive detailed inspections for 
damaged and detached WLPAs and BOPs. Corrective actions include repair. 
You may examine the MCAI on the Internet at http://www.regulations.gov 
by searching for and locating Docket No. FAA-2015-5819.

Related Service Information Under 1 CFR Part 51

    Bombardier has issued the following service information:
     Bombardier Service Bulletin 601R-25-201, dated July 21, 
2015.
     Bombardier Service Bulletin 670BA-25-100, dated July 21, 
2015.
    The service information describes procedures for repetitive 
detailed inspections for damage of the cage assembly, WLPAs, and BOPs, 
and repair and replacement of damaged parts. 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 of this AD.

FAA's Determination and Requirements of This 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 issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of these 
same type designs.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because a 
detached WLPA or BOP could delay smoke detection in the cargo 
compartment, and in the event of a cargo compartment fire, this could 
lead to an uncontrolled cargo compartment fire. Therefore, we 
determined that notice and opportunity for public comment before 
issuing this AD are impracticable and that good cause exists for making 
this amendment effective in fewer than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2015-5819; Directorate 
Identifier 2015-NM-166-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD based on 
those comments.
    We will post all comments we receive, without change, to http://

[[Page 74675]]

www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 986 airplanes of U.S. registry.
    We also estimate that it will take about 2 work-hours per product 
to comply with the basic requirements of this AD. The average labor 
rate is $85 per work-hour. Required parts will cost about $0 per 
product. Based on these figures, we estimate the cost of this AD on 
U.S. operators to be $167,620, or $170 per product.
    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions specified in this AD.

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.
