Airworthiness Directives; Bombardier, Inc. Airplanes
AGENCY: Federal Aviation Administration (FAA), 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 the discovery of a number of
incorrectly calibrated angle of attack (AOA) transducers installed in
the stall protection system. This AD requires replacement of
incorrectly calibrated AOA transducers. We are issuing this AD to
detect and replace incorrectly calibrated AOA transducers; incorrect
calibration of the transducers could result in late activation of the
stick pusher.
DATES: This AD is effective June 6, 2016.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of June 6,
2016.

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-600-2B19 (Regional Jet Series 100&440) airplanes. The NPRM
published in the Federal Register on November 17, 2015 (80 FR 71749)
(``the NPRM''). The NPRM was prompted by the discovery of a number of
incorrectly calibrated AOA transducers installed in the stall
protection system. The NPRM proposed to require replacement of
incorrectly calibrated AOA transducers. We are issuing this AD to
detect and replace incorrectly calibrated AOA transducers; incorrect
calibration of the transducers could result in late activation of the
stick pusher.
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2015-17, effective 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-600-2B19 (Regional Jet
Series 100 & 440) airplanes. The MCAI states:
It was discovered that a number of [angle of attack] AOA
transducers installed on Bombardier CL-600-2B19 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 http://www.regulations.gov by searching for and locating Docket No. FAA-2015-
4814.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
We reviewed the relevant data 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:
Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
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 601R-27-164, dated March
30, 2015. The service information describes procedures for replacement
of incorrectly 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 575 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 $5,945,500, 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
[[Page 26103]]
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
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.
