Airplanes Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC–8–400 series airplanes. This proposed AD was prompted by reports of failure of the high pressure shutoff valves (HPSOVs) causing the timer and monitor unit (TMU) to become inoperative since the HPSOV and the TMU are on the same circuit breaker. This proposed AD would require a wiring modification to segregate the HPSOV power supply from the TMU. We are proposing this AD to prevent an inoperative TMU, which could result in the loss of the automatic de-icing mode, and lead to an increased workload for the flight crew and loss of control of the airplane.

Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority E:\FR\FM\02JAP1.SGM 02JAP1 77 Federal Register / Vol. 79, No. 1 / Thursday, January 2, 2014 / Proposed Rules for Canada, has issued Canadian Airworthiness Directive CF–2013–27, dated September 25, 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: This [TCCA] AD mandates a wiring modification to segregate the HPSOV power supply from the TMU. There have been several in-service reports of the failure of high pressure shutoff valves (HPSOV) causing the Timer and Monitor Unit (TMU) to become inoperative since the HPSOV and TMU are on the same circuit breaker. An inoperative TMU would result in the loss of the automatic de-icing mode and would lead to an increased workload for the flightcrew. In the case where additional failures occur during a critical flight phase, the significantly increased workload could lead to loss of control of the aeroplane. Bombardier, Inc. has issued Service Bulletin 84–36–04, Revision A, dated April 17, 2013. The actions described in this service information are intended to correct the unsafe condition identified in the MCAI. You may obtain further information by examining the MCAI in the AD docket. Relevant Service Information FAA’s Determination and Requirements of This Proposed AD This product has been approved by the aviation authority of another country, and is approved for operation in the United States. Pursuant to our bilateral agreement with the State of Design Authority, we have been notified of the unsafe condition described in the MCAI and service information referenced above. We are proposing this AD because we evaluated all pertinent information and determined an unsafe condition exists and is likely to exist or develop on other products of the same type design. Costs of Compliance We estimate that this proposed AD affects 78 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Parts cost Cost per product Cost on U.S. operators Wiring Modification .......................................... 7 work-hours × $85 per hour = $595 ............. $0 $595 $46,410 mstockstill on DSK4VPTVN1PROD with PROPOSALS 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 proposed AD would not have federalism implications under Executive Order 13132. This proposed AD would 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 this proposed regulation: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; VerDate Mar<15>2010 17:14 Dec 31, 2013 Jkt 232001 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. We prepared a regulatory evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

Section 527.40 Purpose and Scope This section more concisely describes the statutory authority (18 U.S.C. 4100, et seq.) for the Bureau’s procedures for transferring offenders to foreign countries and states that the purpose of this subpart is to describe those procedures. We propose to delete obsolete references to Public Law 95– 144, as it has been codified as 18 U.S.C. 4100, and also propose to delete the recitation of authority which stated that ‘‘18 U.S.C. 4102 authorizes the Attorney General to act on behalf of the United States in regard to such treaties. In accordance with the provisions of 28 CFR 0.96b, the Attorney General has delegated to the Director of the Bureau of Prisons, and to designees of the Director, the authority to receive custody of, and to transfer to and from the United States, offenders in compliance with the conditions of the treaty.’’ This authority is stated elsewhere in regulation and in the Authority section preceding these regulations and is therefore not necessary to repeat in these regulations.

Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Bombardier, Inc. Model DHC-8-400 series airplanes. This 
proposed AD was prompted by reports of failure of the high pressure 
shutoff valves (HPSOVs) causing the timer and monitor unit (TMU) to 
become inoperative since the HPSOV and the TMU are on the same circuit 
breaker. This proposed AD would require a wiring modification to 
segregate the HPSOV power supply from the TMU. We are proposing this AD 
to prevent an inoperative TMU, which could result in the loss of the 
automatic de-icing mode, and lead to an increased workload for the 
flight crew and loss of control of the airplane.

DATES: We must receive comments on this proposed AD by February 18, 
2014.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority

[[Page 77]]

for Canada, has issued Canadian Airworthiness Directive CF-2013-27, 
dated September 25, 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:

    There have been several in-service reports of the failure of 
high pressure shutoff valves (HPSOV) causing the Timer and Monitor 
Unit (TMU) to become inoperative since the HPSOV and TMU are on the 
same circuit breaker.
    An inoperative TMU would result in the loss of the automatic de-
icing mode and would lead to an increased workload for the 
flightcrew. In the case where additional failures occur during a 
critical flight phase, the significantly increased workload could 
lead to loss of control of the aeroplane.
    This [TCCA] AD mandates a wiring modification to segregate the 
HPSOV power supply from the TMU.

    You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    Bombardier, Inc. has issued Service Bulletin 84-36-04, Revision A, 
dated April 17, 2013. The actions described in this service information 
are intended to correct the unsafe condition identified in the MCAI.

FAA's Determination and Requirements of This Proposed AD

    This product has been approved by the aviation authority of another 
country, and is approved for operation in the United States. Pursuant 
to our bilateral agreement with the State of Design Authority, we have 
been notified of the unsafe condition described in the MCAI and service 
information referenced above. We are proposing this AD because we 
evaluated all pertinent information and determined an unsafe condition 
exists and is likely to exist or develop on other products of the same 
type design.

Costs of Compliance

    We estimate that this proposed AD affects 78 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

                                       hour = $595.
----------------------------------------------------------------------------------------------------------------

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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 this proposed 
regulation:
    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.
    We prepared a regulatory evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.

Sec.  39.13  [Amended]

2. The FAA amends Sec.  39.13 by adding the following new airworthiness 
directive (AD):

Bombardier, Inc.: Docket No. FAA-2013-1068; Directorate Identifier 
2013-NM-196-AD.

(a) Comments Due Date

    We must receive comments by February 18, 2014.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bombardier, Inc. Model DHC-8-400, -401, and -
402 airplanes, certificated in any category, serial numbers 4001 
through 4446 inclusive.

(d) Subject

    Air Transport Association (ATA) of America Code 36, Pneumatic.

(e) Reason

    This AD was prompted by reports of failure of the high pressure 
shutoff valves (HPSOVs) causing the timer and monitor unit (TMU) to 
become inoperative since the HPSOV and the TMU are on the same 
circuit breaker. We are issuing this AD to prevent an inoperative 
TMU, which could result in the loss of the automatic de-icing mode, 
and lead to an increased workload for the flight crew and loss of 
control of the airplane.

(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) Segregation of the HPSOV Power Supply From the TMU

    Within 2,000 flight hours or 12 months after the effective date 
of this AD, whichever occurs first: Do a wiring modification to 
segregate the HPSOV power supply from the TMU by incorporating 
Bombardier ModSum 4-110595, in accordance with the Accomplishment 
Instructions of Bombardier

Service Bulletin 84-36-04, Revision A, dated April 17, 2013.

(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 84-36-04, dated 
March 13, 2013.

(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

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, use these actions if they 
are FAA-approved. Corrective actions are considered FAA-approved if 
they were approved by the State of Design Authority (or its 
delegated agent, or by the DAH with a State of Design Authority's 
design organization approval). For a repair method to be approved, 
the repair approval must specifically refer to this AD. You are 
required to ensure the product is airworthy before it is returned to 
service.
