Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2014–30, dated September 5, 2014 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition VerDate Sep<11>2014 16:40 Dec 31, 2015 Jkt 238001 for certain Bombardier, Inc. Model CL– 600–2B16 (CL–604 Variant) airplanes. The MCAI states: A revision has been made to the CL 604/ 605 Time Limits/Maintenance Checks (TLMC) manual, to introduce new tasks for the HSTA. Failure to comply with the TLMC tasks could lead to an unsafe condition. This [Canadian] AD is issued to ensure that premature wear and cracking of the affected components are detected and corrected. The unsafe condition is premature wear and cracking of the HSTA, which could result in failure of the HSTA and consequent loss of control of the airplane. You may examine the MCAI in the AD docket on the Internet at http:// www.regulations.gov by searching for and locating Docket No. FAA–2015– 8129. 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. This proposed AD would require revising the maintenance or inspection program to incorporate new airworthiness limitations for the HSTA. Related Service Information Under 1 CFR Part 51 Bombardier Inc. has issued the following service information. • For Model CL–600–2B16 (CL–604 Variant) airplanes, serial numbers 5301 through 5665 inclusive: Task 27–42–01– 109, Restoration (Overhaul) of the Horizontal Stabilizer Trim Actuator, Part No. 604–92305–7 and Subs (Vendor Part No. 8454–3 and Subs); and Task 27–42–01–111, Detailed Inspection of the Horizontal Trim Actuator (HSTA) Secondary Load Path Indicator, Part No. 604–92305–7 and Subs (Vendor Part No. 8454–3 and Subs); of Section 5–10–40, Certification Maintenance Requirements, of Part 2, Airworthiness Limitations, Revision 22, dated July 11, 2014, of the Bombardier Challenger 604 Time Limits/Maintenance Checks Manual. • For Model CL–600–2B16 (CL–604 Variant) airplanes, serial numbers 5701 through 5962 inclusive: Task 27–42–01– 109, Restoration (Overhaul) of the Horizontal Stabilizer Trim Actuator, PO 00000 Frm 00012 Fmt 4702 Sfmt 4702 33 Part No. 604–92305–7 and Subs (Vendor Part No. 8454–3 and Subs); and Task 27–42–01–111, Detailed Inspection of the Horizontal Trim Actuator (HSTA) Secondary Load Path Indicator, Part No. 604–92305–7 and Subs (Vendor Part No. 8454–3 and Subs); of Section 5–10–40, Certification Maintenance Requirements, of Part 2, Airworthiness Limitations, Revision 10, dated July 11, 2014, of the Bombardier Challenger 605 Time Limits/Maintenance Checks Manual. The service information describes procedures for revising the maintenance or inspection program to incorporate new airworthiness limitations for the HSTA. 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 of this NPRM. Costs of Compliance We estimate that this proposed AD affects 78 airplanes of U.S. registry. We also estimate that it would take about 1 work-hour per product to comply with the basic requirements of this proposed AD. The average labor rate is $85 per work-hour. Based on these figures, we estimate the cost of this proposed AD on U.S. operators to be $6,630, or $85 per product. 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 E:\FR\FM\04JAP1.SGM 04JAP1 34 Federal Register / Vol. 81, No. 1 / Monday, January 4, 2016 / Proposed Rules distribution of power and responsibilities among the various levels of government.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-30, dated September 5, 2014 (referred to after this as the 
Mandatory Continuing Airworthiness Information, or ``the MCAI''), to 
correct an unsafe condition for certain Bombardier, Inc. Model CL-600-
2B16 (CL-604 Variant) airplanes. The MCAI states:

    A revision has been made to the CL 604/605 Time Limits/
Maintenance Checks (TLMC) manual, to introduce new tasks for the 
HSTA. Failure to comply with the TLMC tasks could lead to an unsafe 
condition.
    This [Canadian] AD is issued to ensure that premature wear and 
cracking of the affected components are detected and corrected.

    The unsafe condition is premature wear and cracking of the HSTA, 
which could result in failure of the HSTA and consequent loss of 
control of the airplane. You may examine the MCAI in the AD docket on 
the Internet at http://www.regulations.gov by searching for and 
locating Docket No. FAA-2015-8129.

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.
    This proposed AD would require revising the maintenance or 
inspection program to incorporate new airworthiness limitations for the 
HSTA.

limitations for the HSTA. 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 of this NPRM.

Costs of Compliance

    We estimate that this proposed AD affects 78 airplanes of U.S. 
registry.
    We also estimate that it would take about 1 work-hour per product 
to comply with the basic requirements of this proposed AD. The average 
labor rate is $85 per work-hour. Based on these figures, we estimate 
the cost of this proposed AD on U.S. operators to be $6,630, or $85 per 
product.

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

[[Page 34]]

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.

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

Bombardier, Inc.: Docket No. FAA-2015-8129; Directorate Identifier 
2014-NM-197-AD.

(a) Comments Due Date

    We must receive comments by February 18, 2016.

(b) Affected ADs

    None.

(c) Applicability

    This AD applies to Bombardier, Inc. Model CL-600-2B16 (CL-604 
Variant) airplanes, certificated in any category, serial numbers 
5301 through 5665 inclusive, and 5701 through 5962 inclusive.

(d) Subject

    Air Transport Association (ATA) of America Code 27, Flight 
Controls.

(e) Reason

    This AD was prompted by a determination that certain maintenance 
tasks for the horizontal stabilizer trim actuator (HSTA) are 
inadequate. We are issuing this AD to detect and correct premature 
wear and cracking of the HSTA, which could result in failure of the 
HSTA and consequent loss of control of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Maintenance or Inspection Program Revision

    Within 30 days after the effective date of this AD: Revise the 
maintenance or inspection program, as applicable, to incorporate 
Task 27-42-01-109, Restoration (Overhaul) of the Horizontal 
Stabilizer Trim Actuator, Part No. 604-92305-7 and Subs (Vendor Part 
No. 8454-3 and Subs); and Task 27-42-01-111, Detailed Inspection of 
the Horizontal Trim Actuator (HSTA) Secondary Load Path Indicator, 
Part No. 604-92305-7 and Subs (Vendor Part No. 8454-3 and Subs); of 
the applicable document identified in paragraph (g)(1) or (g)(2) of 
this AD.
    (1) For Model CL-600-2B16 (CL-604 Variant) airplanes, serial 
numbers 5301 through 5665 inclusive: Section 5-10-40, Certification

(h) No Alternative Actions or Intervals

    After the maintenance or inspection program has been revised, as 
required by paragraph (g) of this AD, no alternative actions (e.g., 
inspections) or intervals may be used unless the actions or 
intervals are approved as an alternative method of compliance (AMOC) 
in accordance with the procedures specified in paragraph (i)(1) of 
this AD.

(i) Other FAA AD Provisions

    The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager, New
