14 CFR Part 39

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.
