This AD was prompted by multiple reports of a short circuit between the heater element and the metal sheath of the pitot-static probe heater. This AD requires replacement of the left and right pitot-static probes with newly redesigned left and right pitot-static probes. We are issuing this AD to prevent degradation of the heating ability of the pitot- static probe heater, resulting in erroneous airspeed indication during flight in icing conditions and consequent reduced controllability of the airplane.

-----------------------------------------------------------------------
SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Bombardier, Inc. Model BD-100-1A10 (Challenger 300) airplanes. This AD
was prompted by multiple reports of a short circuit between the heater
element and the metal sheath of the pitot-static probe heater. This AD
requires replacement of the left and right pitot-static probes with
newly redesigned left and right pitot-static probes. We are issuing
this AD to prevent degradation of the heating ability of the pitot-
static probe heater, resulting in erroneous airspeed indication during
flight in icing conditions and consequent reduced controllability of
the airplane.
DATES: This AD becomes effective March 8, 2016.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of March 8,
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 BD-100-1A10 (Challenger 300) airplanes. The NPRM published in the
Federal Register on July 31, 2015 (80 FR 45617).
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian AD CF-2015-04, dated March
17, 2015 (referred to after this as the Mandatory Continuing
Airworthiness Information, or ``the MCAI''), to correct an unsafe
condition for certain Bombardier, Inc. Model BD-100-1A10 (Challenger
300) airplanes. The MCAI states:
There have been several reports where the pitot-static probe
heater came on and remained on regardless of the heater control
selected position. Investigation determined that the root cause is a
short circuit between the heater element and the metal sheath. If
not corrected, this condition may degrade the heating, resulting in
erroneous Airspeed Indication when flying in icing condition [and
consequent reduced controllability of the airplane].
This [Canadian] AD mandates the replacement of the pitot-static
probes with a redesigned probe which will prevent this failure mode.
You may examine the MCAI in the AD docket on the Internet at <a href="http://www.regulations.gov/#!documentDetail">http://www.regulations.gov/#!documentDetail</a>;D=FAA-2015-3140-0002.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (80 FR 45617, July 31,
2015) 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:
<bullet> Are consistent with the intent that was proposed in the
NPRM (80 FR 45617, July 31, 2015) for correcting the unsafe condition;
and
<bullet> Do not add any additional burden upon the public than was
already proposed in the NPRM (80 FR 45617, July 31, 2015).
Related Service Information Under 1 CFR Part 51
Bombardier issued Service Bulletin 100-34-38, dated January 9,
2014. The service information describes procedures for replacement of
the left and right pitot-static probes with newly redesigned left and
right pitot-static probes, part numbers 0856WC3 and 0856WC4
respectively. 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 126 airplanes of U.S. registry.
We also estimate that it will take about 12 work-hours 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 $13,468 per
product. Based on these figures, we estimate the cost of this AD on
U.S. operators to be $1,825,488, or $14,488 per product.
According to the manufacturer, some of the costs of this AD may be
covered under warranty, thereby reducing the cost impact on affected
individuals. We do not control warranty coverage for affected
individuals. As a result, we
[[Page 5366]]
have included all costs in our cost estimate.
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.

You may examine the AD docket on the Internet at <a href="http://www.regulations.gov/#!docketDetail">http://www.regulations.gov/#!docketDetail</a>;D=FAA-2015-3140; or in person at the
Docket Management Facility between 9 a.m. and 5 p.m., Monday through
