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

DATES: This AD becomes effective April 17, 2013.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of April 17, 
2013.

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR 
part 39 to include an AD that would apply to the specified products. 
That NPRM was published in the Federal Register on July 19, 2012 (77 FR 
42457). That NPRM proposed to correct an unsafe condition for the 
specified products. The Mandatory Continuing Airworthiness Information 
(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 [Canadian] AD mandates the replacement of existing cargo 
compartment liners with compliant cargo compartment liners.
    Aeroplanes modified with [Transport Canada Civil Aviation] 
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 [Canadian] 
AD.

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

Comments

    We gave the public the opportunity to participate in developing 
this AD. We considered the comments received.

Request To Change Applicability

    Air Wisconsin (AWI) requested that we change the applicability to 
either specify airplane serial numbers (S/Ns) 7003 though 7067 
inclusive, and S/Ns 7069 through 7857 inclusive, including airplanes 
modified by STC ST01292NY, amended July 7, 2003 (http://www.airweb.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/1BB5140B1D3A130086256D7A006DF851?OpenDocument&Highlight=st01292ny); or 
specify the airplanes listed in 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. AWI stated that the NPRM (77 FR 
42457, July 19, 2012) specifies the applicability as airplane S/Ns 7003 
and subsequent, yet each of these Bombardier service bulletins 
describes the effectivity as airplane S/Ns 7003 thru 7067 inclusive and 
S/Ns 7069 thru 7857 inclusive, and states that the service bulletin was 
``validated'' on airplane S/N 7362.
    We do not agree with the commenter's request to change the 
applicability. The intent of this AD is to ensure that any Model CL-
600-2B19 airplane configured with a Class C cargo compartment be 
equipped with compliant cargo compartment liners. The Bombardier 
service information referenced in paragraphs (g)(1) through (g)(3) of 
this AD has listed airplanes with known Class C cargo compartments. In 
order to ensure that any subsequently converted airplanes will be 
equally equipped with compliant Class C cargo compartment liners, this 
AD must apply to any Model CL-600-2B19 airplane configured with a Class 
C cargo compartment. We have not changed the AD in this regard.

Requests To Extend Compliance Time

    AWI and Pinnacle Airlines (FLG) requested that we extend the 
compliance time from 28 months to 36 months after the effective date of 
the AD. Both commenters stated that the service information recommends 
a compliance time of 36 months. Additionally, both commenters stated 
that the manufacturer has yet to supply the necessary parts kits. FLG 
noted that, without the parts kits, it could be put in a position of 
parking its airplanes. AWI stated that, without kits available, 
airplanes that are currently having their heavy check visits completed 
are without the benefit of the cargo compartment liner modification 
being accomplished.
    We do not agree with the commenters' requests to extend the 
compliance time. In developing an appropriate compliance time for this 
action, we considered the safety implications, parts availability, and 
normal maintenance schedules for the timely accomplishment of the 
modification. Bombardier has confirmed with the FAA and Transport 
Canada Civil Aviation (TCCA) that parts are available to the operators, 
and the availability will be such that the operators will be able to 
incorporate the modification within the compliance time. However, under 
the provisions of paragraph (k) of this AD, we will consider requests 
for approval of an extension of the compliance time if sufficient data 
are submitted to substantiate that the new compliance time would 
provide an acceptable level of safety. We have not changed the AD in 
this regard.

Request To Change Date of Parts Installation Prohibition or Remove 
Prohibition

    AWI requested that we either remove the paragraph or change the 
date of the prohibition of the installation of the old style liners 
(paragraph (i) of the NPRM (77 FR 42457, July 19, 2012)) from the 
effective date of the AD to 28 months after the effective date of the 
AD. AWI stated that in order to maintain a pre-modification airplane 
until the modification required by paragraph (g) of the NPRM is 
performed, the operator needs to have the flexibility to install the 
old style liners when replacing any that might become damaged.
    We agree to change the date of the prohibition of the installation 
of the old style liners for certain airplanes. We have changed 
paragraph (j)(1) of this AD (referred to as paragraph (i) of the NPRM 
(77 FR 42457, July 19, 2012)) to state that the installation of the old 
style liners for airplane S/Ns 7003 through 7857 inclusive is 
prohibited after completion of the cargo compartment liner modification 
required by paragraph (g) of this AD, which is required within 28 
months after the effective date of this AD.
    We have also added new paragraph (j)(2) to this AD, which states 
that the installation of the old style liners for airplane S/Ns 7858 
and subsequent is prohibited as of the effective date of this AD. 
Airplane S/Ns 7858 and subsequent are/were not delivered with a class C 
cargo compartment. Paragraph (j)(2) of this AD prevents these airplanes 
from having the identified unsafe cargo liners installed if they are 
converted to class C cargo compartments.

Request To Use Certain STC Parts

    AWI requested that we change the NPRM (77 FR 42457, July 19, 2012) 
to allow the installation of inserts, which are necessary for the 
installation of the rear wall liners in the floor panels specified in 
STC ST00560NY, amended June 29, 2001 (http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/78C85CD7FA9FAFA585256CC2006A74D0?OpenDocument&Highlight=st00560ny). AWI 
stated that Bombardier Service Bulletin 601R-25-187, Revision A, dated 
September 1, 2011, does not mention these aftermarket panels and 
recognizes only the original equipment manufacturer floor panels.
    We agree with the commenter's request. We have added new paragraph 
(h) to this AD, which states that Comtek Advanced Structures floor 
panels

[[Page 15872]]

approved under STC ST00560NY, amended June 29, 2001 (http://rgl.faa.gov/Regulatory_and_Guidance_Library/rgstc.nsf/0/78C85CD7FA9FAFA585256CC2006A74D0?OpenDocument&Highlight=st00560ny), are 
considered equivalent to the original equipment floor panels described 
in Bombardier Service Bulletin 601R-25-187, Revision A, dated September 
1, 2011, and may be used in lieu of the floor panels described in 
Bombardier Service Bulletin 601R-25-187, Revision A, dated September 1, 
2011. We have re-identified subsequent paragraphs accordingly.

Request To Approve Past or Future Repairs

    AWI requested that we make accommodation in the NPRM (77 FR 42457, 
July 19, 2012) for previously approved or future approved repairs/
repair schemes without the need for alternative methods of compliance 
(AMOC) to do those repairs. AWI stated that the cargo compartment 
liners take quite a bit of abuse during loading/unloading operations 
and are frequently in need of repair to maintain serviceability. AWI 
pointed out that there are existing approved repairs for the liners in 
the airplane maintenance manual and/or service repair manual.
    We disagree with the commenter's request. This AD requires the 
installation of compliant cargo compartment liners. After accomplishing 
the actions required by this AD, maintenance and/or preventive 
maintenance under 14 CFR part 45 is permitted provided the maintenance 
does not result in changing the AD-mandated configuration (reference 14 
CFR 39.7). We have not changed the AD in this regard.

Conclusion

    We reviewed the available data, including the comments received, 
and determined that air safety and the public interest require adopting 
the AD with the changes described previously-and minor editorial 
changes. We have determined that these changes:
     Are consistent with the intent that was proposed in the 
NPRM (77 FR 42457, July 19, 2012) for correcting the unsafe condition; 
and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (77 FR 42457, July 19, 2012).

Costs of Compliance

    We estimate that this AD will affect 574 products of U.S. registry. 
We also estimate that it will take about 87 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 $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 this AD to the 
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 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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this AD and placed it in the AD docket.
