ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Bombardier, Inc. Model CL-600-2C10 (Regional Jet Series 700, 701, &
702) airplanes, Model CL-600-2D15 (Regional Jet Series 705) airplanes,
Model CL-600-2D24 (Regional Jet Series 900) airplanes, and Model CL-

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 by adding an AD that would apply to certain Bombardier, Inc.
Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes,
Model CL-600-2D15 (Regional Jet Series 705) airplanes, Model CL-600-
2D24 (Regional Jet Series 900) airplanes, and Model CL-600-2E25
(Regional Jet Series 1000) airplanes. The NPRM published in the Federal
Register on November 12, 2015 (80 FR 69896) (``the NPRM'').
Transport Canada Civil Aviation (TCCA), which is the aviation
authority Canada, has issued Canadian Airworthiness Directive CF-2015-
18, dated July 16, 2015 (referred to after this as the Mandatory
Continuing Airworthiness Information, or ``the MCAI''), to correct an
unsafe condition for certain Bombardier, Inc. Model CL-600-2C10
(Regional Jet Series 700, 701, & 702) airplanes, Model CL-600-2D15
(Regional Jet Series 705) airplanes, Model CL-600-2D24 (Regional Jet
Series 900) airplanes, and Model CL-600-2E25 (Regional Jet Series 1000)
airplanes. The MCAI states:
It was discovered that a number of AOA transducers installed on
Bombardier CL-600-2C10, CL-600-2D15, CL-600-2D24, and CL-600-2E25
aeroplanes were incorrectly calibrated due to a quality control
problem at both the production and repair facilities. Incorrect
calibration of the AOA transducer could result in a late activation
of the stick pusher.
This [Canadian] AD mandates the replacement of the incorrectly
calibrated AOA transducer.
You may examine the MCAI in the AD docket on the Internet at <a href="http://www.regulations.gov">http://www.regulations.gov</a> by searching for and locating Docket No. FAA-2015-
4811.
Comments
We gave the public the opportunity to participate in developing
this AD. We considered the one comment received. The commenter
supported the NPRM.
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
this AD as proposed except for minor editorial changes. We have
determined that these minor changes:
<bullet> Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM.
Related Service Information Under 1 CFR Part 51
We reviewed Bombardier Service Bulletin 670BA-27-069, dated March
30, 2015. This service information
[[Page 21710]]
describes procedures for replacement of transducers with correctly
calibrated AOA transducers. This service information is reasonably
available because the interested parties have access to it through
their normal course of business or by the means identified in the
ADDRESSES section.
Costs of Compliance
We estimate that this AD affects 400 airplanes of U.S. registry.
We also estimate that it would take about 4 work-hours per product
to comply with the basic requirements of this AD. The average labor
rate is $85 per work-hour. Required parts would cost about $10,000 per
product. Based on these figures, we estimate the cost of this AD on
U.S. operators to be $4,136,000, or $10,340 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
Adoption of the Amendment

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 airworthiness
directive (AD):
2016-08-05 Bombardier, Inc.: Amendment 39-18481. Docket No. FAA-
2015-4811; Directorate Identifier 2015-NM-104-AD.
(a) Effective Date

Instructions of Bombardier Service Bulletin 670BA-27-069, dated
March 30, 2015.
(h) Parts Installation Prohibition
