14 CFR Part 39
[Docket No. FAA-2011-0994; Directorate Identifier 2010-NM-143-AD;
Amendment 39-16949; AD 2012-03-08]
RIN 2120-AA64
Airworthiness Directives; Bombardier, Inc. Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are superseding an existing airworthiness directive (AD)
for certain Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series
700, 701, & 702), CL-600-2D15 (Regional Jet Series 705), and CL-600-
2D24 (Regional Jet Series 900) airplanes. That AD currently requires
repetitive detailed inspections for cracking or deformation, or pulled
or missing fasteners, on the lower panel of the left- and right-hand
main landing gear (MLG) doors, as applicable, and corrective actions if
necessary. That AD also reduces the repetitive inspection interval for
certain airplanes. This new AD adds a new modification of the MLG door
configuration, and removes certain airplanes from the applicability.
This AD was prompted by further analysis of the MLG door by the
manufacturer. We are issuing this AD to prevent failure of the lower
panel of the MLG door, departure of the lower panel from the airplane,
and consequent damage to airplane structure, which could adversely
affect the airplane's continued safe flight and landing.
DATES: This AD is effective April 4, 2012.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of April 4, 2012.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2006-14-05, Amendment 39-14676 (71 FR 38979,
July 11, 2006). That AD applies to the specified products. The NPRM was
published in the Federal Register on October 5, 2011 (76 FR 61633).
That NPRM proposed to continue to require repetitive detailed
inspections for cracking or deformation, or pulled or missing
fasteners, on the lower panel of the left- and right-hand main landing
gear (MLG) doors, as applicable, and corrective actions if necessary.
That NPRM also proposed to reduce the repetitive inspection interval
for certain airplanes. In addition, that NPRM proposed to add a new
modification of the MLG door configuration, and remove certain
airplanes from the applicability.
Comments
We gave the public the opportunity to participate in developing
this AD. We have considered the comment received. The Air Line Pilots
Association International supports the NPRM (76 FR 61633, October 5,
2011).
Explanation of Changes Made to This AD
We have revised certain headers throughout this AD. We have also
revised the wording in paragraphs (q) and (s) of this AD; this change
has not changed the intent of these paragraphs.
Conclusion
We reviewed the available data, including the comment 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 minor changes:
Are consistent with the intent that was proposed in the
NPRM (76 FR 61633, October 5, 2011) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (76 FR 61633, October 5, 2011).
Costs of Compliance
We estimate that this AD affects about 220 products of U.S.
registry.
The actions that are required by AD 2006-14-05, Amendment 39-14676
(71 FR 38979, July 11, 2006), and retained in this AD take about 3
work-hours per product, at an average labor rate of $85 per work hour.
Based on these figures, the estimated cost of the currently required
actions is $255 per product.
We estimate that it will take about 115 work-hours per product to
comply with the new basic requirements of this AD. The average labor
rate is $85 per work-hour. Required parts will cost about $0 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 costs. 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 AD on U.S.
operators to be $2,150,500, or $9,775 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 have 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 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.

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 removing airworthiness directive (AD)
2006-14-05, Amendment 39-14676 (71 FR 38979, July 11, 2006), and adding
the following new AD:
2012-03-08 Bombardier Inc.: Amendment 39-16949; Docket No. FAA-2011-
0994; Directorate Identifier 2010-NM-143-AD.
(a) Effective Date
This airworthiness directive (AD) is effective April 4, 2012.
(b) Affected ADs
This AD supersedes AD 2006-14-05, Amendment 39-14676 (71 FR
38979, July 11, 2006).
(c) Applicability
This AD applies to Bombardier, Inc. Model CL-600-2C10 (Regional
Jet Series 700, 701, & 702) airplanes having serial numbers (S/Ns)

prevent failure of the lower panel of the MLG door, departure of the
lower panel from the airplane, and consequent damage to airplane
structure, which could adversely affect the airplane's continued
safe flight and landing.
