SUPPLEMENTARY INFORMATION: We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model BD–700–1A10 airplanes. This AD was prompted by a report that the 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. Since the drain mast heaters are connected in parallel with the number 2 pitot static (PS) probe heater circuit, a number 2 PS probe heater failure may not be detected by the fault monitoring capabilities of the HBMU. This AD requires modification of the air data probes and sensors. We are issuing this AD to detect and correct an unannunciated failure of two PS probe heaters, which could affect controllability of the airplane in icing conditions. DATES: This AD becomes effective April 1, 2014. The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of April 1, 2014. ADDRESSES: You may examine the AD docket on the Internet at https:// www.regulations.gov/ 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–700–1A10 airplanes. The NPRM published in the Federal Register on September 11, 2013 (78 FR 55660). The NPRM was prompted by a report that the 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. Since the drain mast heaters are connected in parallel with the number 2 pitot static (PS) probe heater circuit, a number 2 PS probe heater failure may not be detected by the fault monitoring capabilities of the HBMU. The NPRM proposed to require modification of the air data probes and sensors. We are issuing this AD to detect and correct an unannunciated failure of two PS probe heaters, which could affect controllability of the airplane in icing conditions. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2012–32, This section of the FEDERAL REGISTER contains regulatory documents having general applicability and legal effect, most of which are keyed to and codified in the Code of Federal Regulations, which is published under 50 titles pursuant to 44 U.S.C. 1510.

Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Bombardier, Inc. Model BD-700-1A10 airplanes. This AD was prompted by a 
report that the 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. Since the drain 
mast heaters are connected in parallel with the number 2 pitot static 
(PS) probe heater circuit, a number 2 PS probe heater failure may not 
be detected by the fault monitoring capabilities of the HBMU. This AD 
requires modification of the air data probes and sensors. We are 
issuing this AD to detect and correct an unannunciated failure of two 
PS probe heaters, which could affect controllability of the airplane in 
icing conditions.

DATES: This AD becomes effective April 1, 2014.

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-700-1A10 airplanes. The NPRM published in the Federal Register 
on September 11, 2013 (78 FR 55660). The NPRM was prompted by a report 
that the 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. Since the drain mast heaters 
are connected in parallel with the number 2 pitot static (PS) probe 
heater circuit, a number 2 PS probe heater failure may not be detected 
by the fault monitoring capabilities of the HBMU. The NPRM proposed to 
require modification of the air data probes and sensors. We are issuing 
this AD to detect and correct an unannunciated failure of two PS probe 
heaters, which could affect controllability of the airplane in icing 
conditions.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2012-32, dated December 13, 2013 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for the specified products. 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 https://www.regulations.gov/#!documentDetail;D=FAA-2013-0705-0002.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the NPRM (78 FR 55660, September 
11, 2013) 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 (78 FR 55660, September 11, 2013) for correcting the unsafe 
condition; and
     Do not add any additional burden upon the public than was 
already proposed in the NPRM (78 FR 55660, September 11, 2013).

Costs of Compliance

    We estimate that this AD affects 32 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

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

List of Subjects in 14 CFR Part 39

    Air transportation, Aircraft, Aviation safety, Incorporation by 
reference, Safety.

Adoption of the Amendment

    Accordingly, under the authority delegated to me by the 
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 AD:

2014-03-05 Bombardier, Inc.: Amendment 39-17742. Docket No. FAA-
2013-0705; Directorate Identifier 2013-NM-052-AD.

(a) Effective Date

    This airworthiness directive (AD) becomes effective April 1, 
2014.

(b) Affected ADs

    None.

(c) Applicability

    (1) This AD applies to Bombardier, Inc. Model BD-700-1A10 
airplanes, certificated in any category, equipped with any 
electrical wiring heater current/brake temperature monitor unit 
(HBMU) installed in accordance with any FAA supplemental type 
certificate specified in table 1 of paragraph 1.A., ``Effectivity,'' 
of Bombardier Service Bulletin 700-30-021, Revision 01, dated 
November 21, 2012.
    (2) For airplanes on which the applicable service request for 
product support action (SRPSA) specified in table 3 and table 4 of 
paragraph 1.A., ``Effectivity,'' of Bombardier Service Bulletin 700-
30-021, Revision 01, dated November 21, 2012, has been incorporated, 
the requirements of this AD have been met.

(d) Subject

    Air Transport Association (ATA) of America Code 30, Ice and Rain 
Protection.

(e) Reason

    This AD was prompted by a report that the manufacturer has 
determined that some completion centers used the 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. We are issuing this AD to 
detect and correct an unannunciated failure of two PS probe heaters, 
which could affect controllability of the airplane in icing 
conditions.

(f) Compliance

    You are responsible for having the actions required by this AD 
performed within the compliance times specified, unless the actions 
have already been done.

(g) Modification

    Within 800 flight hours or 15 months after the effective date of 
this AD, whichever occurs first: Modify the air data probes and 
sensors, in accordance with the Accomplishment Instructions of 
Bombardier Service Bulletin 700-30-021, Revision 01, dated November 
21, 2012.

(h) Credit for Previous Actions

    This paragraph provides credit for actions required by paragraph 
(g) of this AD, if those actions were performed before the effective 
date of this AD using Bombardier Service Bulletin 700-30-021, dated 
August 28, 2012, which is not incorporated by reference in this AD.

(i) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, New 
York Aircraft Certification Office (ACO), ANE-170, FAA, has the 
authority to approve AMOCs for this AD, if requested using the 
procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, 
send your request to your principal inspector or local Flight 
Standards District Office, as appropriate. If sending information

Operational Safety, FAA, New York ACO, 1600 Stewart Avenue, Suite 
410, Westbury, NY 11590; telephone 516-228-7300; fax 516-794-5531. 
Before using any approved AMOC, notify your appropriate principal 
inspector, or lacking a principal inspector, the manager of the 
local flight standards district office/certificate holding district 
office. The AMOC approval letter must specifically reference this 
AD.
    (2) Airworthy Product: For any requirement in this AD to obtain 
corrective actions from a manufacturer or other source, use these 
actions if they are FAA-approved. Corrective actions are considered 
FAA-approved if they are approved by the State of Design Authority

[[Page 10333]]

(or their delegated agent). You are required to assure the product 
is airworthy before it is returned to service.
