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 reports that airplanes 
with a Class C cargo (baggage) compartment have liners that do not meet 
flammability requirements. This proposed AD would require replacing the 
existing cargo compartment liners with liners that comply. We are 
proposing this AD to prevent inadequate fire protection in the cargo 
compartment and consequent uncontrolled fire.

DATES: We must receive comments on this proposed AD by September 4, 
2012.

ADDRESSES: You may send comments by any of the following methods:
     Federal eRulemaking Portal: Go to http://www.regulations.gov. Follow the instructions for submitting comments.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian AD CF-2012-11, dated March 
23, 2012 (referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    It was found that the cargo compartment liners installed on CL-
600-2B19 configured with Class C cargo compartment do not all meet 
the flammability requirements. Non-compliant cargo compartment 
liners may not provide adequate fire protection and could lead to an 
uncontrolled baggage bay fire.
    This AD mandates the replacement of existing cargo compartment 
liners with compliant cargo compartment liners.
    Aeroplanes modified with [TCCA] Supplemental Type Certificate 
(STC) Number SA01-19 Issue No. 1 [corresponding FAA STC ST01292NY, 
amended July 7, 2003 http://www.airweb.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/1BB5140B1D3A130086256D7A006DF851?OpenDocument&Highlight=st01292ny] 
Cargo Liner Replacement Panels are also affected by this AD.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Bombardier, Inc. issued the following service information:
     Bombardier Service Bulletin 601R-25-187, Revision A, dated 
September 1, 2011;
     Bombardier Service Bulletin 601R-25-198, dated September 
1, 2011; and
     Bombardier Service Bulletin 601R-25-199, dated September 
1, 2011.
    Comtek Aftermarket Structures issued COMTEK Service Bulletin COMSB-
25-52-001, Revision A, dated December 29, 2011.
    The actions described in this service information are intended to 
correct the unsafe condition identified in the MCAI.

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

    Based on the service information, we estimate that this proposed AD 
would affect about 574 products of U.S. registry. We also estimate that 
it would take about 87 work-hours per product to comply with the basic 
requirements of this proposed AD. The average labor rate is $85 per 
work-hour. Required parts would cost about $43,559 per product. Where 
the service information lists required parts costs that are covered 
under warranty, we have assumed that there will be no charge for these 
parts. As we do not control warranty coverage for affected parties, 
some parties may incur costs higher than estimated here. Based on these 
figures, we estimate the cost of the proposed AD on U.S. operators to 
be $29,247,596, or $50,954 per product.

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
    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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with

[[Page 42459]]

this proposed AD and placed it in the AD docket.

principal inspector, or lacking a principal inspector, the manager 
of the local flight standards district office/certificate holding 
district office. The AMOC approval letter must specifically 
reference this AD.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority 
(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
