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-600-1A11 (CL-600), CL-600-2A12 (CL-601), and
CL-600-2B16 (CL-601-3A, CL-601-3R, & CL-604 Variants) airplanes. This
AD was prompted by reports of cracking found on the upper and lower Web
of the engine support beam. This AD requires revising the maintenance
program. We are issuing this AD to detect and correct fatigue cracking
of the engine support beam, which could result in failure of the engine
support beam and affect the structural integrity of the airplane.
DATES: This AD becomes effective March 19, 2013.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in this AD as of March 19,
2013.
ADDRESSES: You may examine the AD docket on the Internet at http://www.regulations.gov or in person at the U.S. Department of
Transportation, Docket Operations, M-30, West Building Ground Floor,

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 31, 2012 (77 FR
45288). That NPRM proposed to correct an unsafe condition for the
specified products. The Mandatory Continuing Airworthiness Information
(MCAI) states:
Cracks on the upper and lower Web of the Engine Support Beam
(ESB) have been discovered on two (2) Challenger aeroplanes in
service. Failure of the ESB could adversely affect the structural
integrity of the aeroplane.
A Temporary Revision (TR) has been made to the Time Limits/
Maintenance Checks (TLMC) manual to introduce a new Airworthiness
Limitations (AWL) task to ensure that fatigue cracking of the ESB is
detected and corrected.
This [Canadian] directive mandates the incorporation of the new
AWL task.
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 received no comments on the NPRM (77 FR 45288, July 31,
2012) or on the determination of the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed--except for
minor editorial changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM (77 FR
[[Page 9784]]
45288, July 31, 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 45288, July 31, 2012).
Costs of Compliance
We estimate that this AD will affect 111 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. Based on these figures, we estimate the cost of
this AD to the U.S. operators to be $9,435, or $85 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.
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 (77 FR 45288, July 31, 2012),
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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 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 AD:
2013-03-08 Bombardier, Inc.: Amendment 39-17343. Docket No. FAA-
2012-0725; Directorate Identifier 2011-NM-207-AD.
(a) Effective Date
This airworthiness directive (AD) becomes effective March 19,
2013.
(b) Affected ADs
None.
(c) Applicability
(1) This AD applies to the airplane models specified in
paragraphs (c)(1)(i), (c)(1)(ii), (c)(1)(iii), and (c)(1)(iv) of
this AD, certificated in any category.
(i) Bombardier, Inc. Model CL-600-1A11 (CL-600), serial numbers
1004 through 1085 inclusive.
(ii) Bombardier, Inc. Model CL-600-2A12 (CL-601), serial numbers
3001 through 3066 inclusive.
(iii) Bombardier, Inc. Model CL-600-2B16 (CL-601-3A and CL-601-
3R Variants), serial numbers 5001 through 5194 inclusive.
(iv) Bombardier, Inc. Model CL-600-2B16 (CL-604 Variants),
serial numbers 5301 through 5665 inclusive, and 5701 and subsequent.
(2) This AD requires revisions to certain operator maintenance
documents to include new inspections. Compliance with these
inspections is required by 14 CFR 91.403(c). For airplanes that have
been previously modified, altered, or repaired in the areas
addressed by these inspections, the operator may not be able to
accomplish the inspections described in the revisions. In this
situation, to comply with 14 CFR 91.403(c), the operator must
request approval for an alternative method of compliance according
to paragraph (j) of this AD. The request should include a
description of changes to the required inspections that will ensure
the continued damage tolerance of the affected structure. The FAA
has provided guidance for this determination in FAA Advisory
Circular (AC) 25.1529-1A, dated November 20, 2007 (http://rgl/
Regulatory--and--Guidance--Library/rgAdvisoryCircular.nsf/0/
