Airworthiness Directives; Bombardier, Inc. Model CL-600-2B19 
(Regional Jet Series 100 & 440) Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding an existing airworthiness directive (AD) 
for the products listed above. This AD results from mandatory 
continuing airworthiness information (MCAI) originated by an aviation 
authority of

[[Page 22522]]

another country to identify and correct an unsafe condition on an 
aviation product. The MCAI describes the unsafe condition as:

    AD CF-2002-12 [which corresponds to FAA AD 2003-04-21, amendment 
39-13070] mandated installation of revised overwing emergency exit 
placards showing that the exit door should be opened and disposed 
from a seated position. However, it was later discovered that the 
new placards illustrated an incorrect hand position for removal of 
the exit upper handle cover. These incorrect instructions could 
cause difficulty or delay when opening the overwing emergency exit.

As a result, the timely and safe evacuation of passengers and crew may 
be impeded. We are issuing this AD to require actions to correct the 
unsafe condition on these products.

DATES: This AD becomes effective June 3, 2010.
    The Director of the Federal Register approved the incorporation by 
reference of a certain publication listed in this AD as of June 3, 
2010.
    On April 4, 2003 (68 FR 9509, February 28, 2003), the Director of 
the Federal Register approved the incorporation by reference of a 
certain other publication listed in this AD.

SUPPLEMENTARY INFORMATION: 

Discussion

    We issued a supplemental notice of proposed rulemaking (NPRM) to 
amend 14 CFR part 39 to include an AD that would apply to the specified 
products. That supplemental NPRM was published in the Federal Register 
on December 23, 2009 (74 FR 68198), and proposed to supersede AD 2003-
04-21, Amendment 39-13070 (68 FR 9509, February 28, 2003). That 
supplemental NPRM proposed to correct an unsafe condition for the 
specified products. The MCAI states:

    AD CF-2002-12 [which corresponds to FAA AD 2003-04-21] mandated 
installation of revised overwing emergency exit placards showing 
that the exit door should be opened and disposed from a seated 
position. However, it was later discovered that the new placards 
illustrated an incorrect hand position for removal of the exit upper 
handle cover. These incorrect instructions could cause difficulty or 
delay when opening the overwing emergency exit.

As a result, the timely and safe evacuation of passengers and crew may 
be impeded. The required actions include replacing the incorrect 
placards with revised placards. 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 comment received from the only commenter.

Request To Refer to Updated Service Information

    Air Wisconsin requests that we update the supplemental NPRM to 
refer to the most recent service information. Air Wisconsin notes that 
Bombardier Service Bulletin 601R-11-088, Revision A, dated March 24, 
2009, has been revised. Bombardier has issued Service Bulletin 601R-11-
088, Revision B, dated November 17, 2009.
    We agree to refer to the latest service information. We have 
determined that the actions specified in the revised service bulletin 
are essentially identical to the actions specified in Bombardier 
Service Bulletin 601R-11-088, Revision A, dated March 24, 2009. We have 
revised paragraphs (h) and (k) of this AD to refer to Bombardier 
Service Bulletin 601R-11-088, Revision B, dated November 17, 2009. We 
have revised paragraph (i) of this AD to also give credit for actions 
done in accordance with Bombardier Service Bulletin 601R-11-088, 
Revision A, dated March 24, 2009.

Explanation of Change Made to This AD

    We have revised this AD to identify the legal name of the 
manufacturer as published in the most recent type certificate data 
sheet for the affected airplane models.

Conclusion

    We reviewed the relevant data, considered the comment received, and 
determined that air safety and the public interest require adopting the 
AD with the changes described previously. We also determined that these 
changes will not increase the economic burden on any operator or 
increase the scope of the AD.

Differences Between This AD and the MCAI or Service Information

    We have reviewed the MCAI and related service information and, in 
general, agree with their substance. But we might have found it 
necessary to use different words from those in the MCAI to ensure the 
AD is clear for U.S. operators and is enforceable. In making these 
changes, we do not intend to differ substantively from the information 
provided in the MCAI and related service information.
    We might also have required different actions in this AD from those 
in the MCAI in order to follow our FAA policies. Any such differences 
are highlighted in a Note within the AD.

Explanation of Change to Costs of Compliance

    After the supplemental NPRM was issued, we reviewed the figures we 
have used over the past several years to calculate AD costs to 
operators. To account for various inflationary costs in the airline 
industry, we find it necessary to increase the labor rate used in these 
calculations from $80 per work hour to $85 per work hour. The cost 
impact information, below, reflects this increase in the specified 
hourly labor rate.

Costs of Compliance

    We estimate that this AD will affect 664 products of U.S. registry. 
We also estimate that it will take about 1 work-hour 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 $128 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 $141,432, or $213 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

[[Page 22523]]

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 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); and
    3. 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.

Examining the AD Docket

    You may examine the AD docket on the Internet at http://
www.regulations.gov; or in person at the Docket Operations office 
between 9 a.m. and 5 p.m., Monday through Friday, except Federal 
holidays. The AD docket contains the NPRM, the regulatory evaluation, 
any comments received, and other information. The street address for 
the Docket Operations office (telephone (800) 647-5527) is in the 
ADDRESSES section. Comments will be available in the AD docket shortly 
after receipt.

    (a) This airworthiness directive (AD) becomes effective June 3, 
2010.

Affected ADs

    (b) This AD supersedes AD 2003-04-21 R1, Amendment 39-13070.

Applicability

    (c) 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.

Subject

    (d) Air Transport Association (ATA) of America Code 11: Placards
