Airworthiness Directives; Bombardier, Inc. Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are superseding Airworthiness Directive (AD) 2014-03-05,
for certain Bombardier, Inc. Model BD-700-1A10 airplanes. AD 2014-03-05
required modification of the air data probes and sensors. This new AD
continues to require modification of the air data probes and sensors.
This new AD also adds airplanes to the applicability. This AD was
prompted by a report that the manufacturer has determined that some
completion centers used the heater current/brake temperature monitor
unit (HBMU) logic circuit to control the line voltage of the drain mast
heaters. We are issuing this AD to detect and correct an unannunciated
failure of two pitot static probe heaters, which could affect
controllability of the airplane in icing conditions.
DATES: This AD becomes effective February 19, 2015.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in this AD as of April 1,
2014 (79 FR 10331, February 25, 2014).

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede AD 2014-03-05, Amendment 39-17742 (79 FR 10331,
February 25, 2014).
AD 2014-03-05 applied to certain Bombardier, Inc. Model BD-700-1A10
airplanes. The NPRM published in the Federal Register on August 26,
2014 (79 FR 50880).
Transport Canada Civil Aviation (TCCA), which is the aviation
authority for Canada, has issued Canadian Airworthiness Directive CF-
2012-32, dated December 13, 2012 (referred to after this as the
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to
correct an unsafe condition for certain Bombardier, Inc. Model BD-700-
1A10 airplanes. The MCAI states:
The aeroplane manufacturer has determined that some completion
centers used the Heater/Brake Monitoring Unit (HBMU) logic circuit
to control the line voltage of the drain mast heaters. This same
logic circuit is also used to control the line voltage of the number
2 pitot static (PS) probe heater. Since the drain mast heaters are
connected in parallel with the number 2 PS probe heater circuit, a
number 2 PS probe heater failure may not be detected by the fault
monitoring capabilities of the HBMU.
The unannunciated failure of two PS probe heaters could
adversely affect the aeroplane's flight characteristics in icing
conditions.
This [Canadian] AD mandates a modification to the existing drain
mast heater wiring to correct the fault-monitoring capabilities of
the HBMU and eliminate the potential dormant failure of the number 2
PS probe heater.
You may examine the MCAI in the AD docket on the Internet at http://www.regulations.gov/#!documentDetail;D=FAA-2014-0582-0002.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM (79 FR 50880, August 26,
2014) or on the determination of the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the
[[Page 2000]]
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 (79 FR 50880, August 26, 2014) for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was
already proposed in the NPRM (79 FR 50880, August 26, 2014).
Costs of Compliance
We estimate that this AD affects 79 airplanes of U.S. registry.
The actions required by AD 2014-03-05, Amendment 39-17742 (79 FR
10331, February 25, 2014), and retained in this AD take about 35 work-
hours per product, at an average labor rate of $85 per work-hour.
Required parts cost about $0 per product. Based on these figures, the
estimated cost of the actions that were required by AD 2014-03-05 is
$2,975 per product.
We also estimate that it will take about 35 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. Based on these figures, we estimate the cost of this AD on
U.S. operators to be $235,025, or $2,975 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 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 http://www.regulations.gov/#!docketDetail;D=FAA-2014-0582; or in person at the
Docket Management Facility between 9 a.m. and 5 p.m., Monday through
Friday, except Federal holidays. The AD docket contains this AD, the
regulatory evaluation, any comments received, and other information.
