RIN 2120–AA64 Examining the AD Docket This section of the FEDERAL REGISTER contains notices to the public of the proposed issuance of rules and regulations. The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 Airworthiness Directives; Bombardier, Inc., 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 CL–600–1A11 (CL–600), CL–600–2A12 (CL–601 Variant), and CL–600–2B16 (CL–601– 3A, CL–601–3R, and CL–604 Variants) airplanes. This proposed AD was prompted by reports of fractured rudder pedal tubes on the pilot-side rudder bar assembly. This proposed AD would require repetitive inspections of the rudder pedal tubes for cracking and corrective actions if necessary. Replacement of both pilot-side rudder bar assemblies is terminating action for the inspections. We are proposing this AD to address the unsafe condition on these products. DATES: We must receive comments on this proposed AD by December 4, 2017. ADDRESSES: You may send comments, using the procedures found in 14 CFR 11.43 and 11.45, by any of the following methods: • Federal eRulemaking Portal: Go to https://www.regulations.gov.

Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2017–09, dated February 22, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc., Model CL– 600–1A11 (CL–600), CL–600–2A12 (CL– 601 Variant), and CL–600–2B16 (CL– 601–3A, CL–601–3R, and CL–604 Variants) airplanes. The MCAI states: There have been two in-service reports of fractured rudder pedal tubes installed on the pilot-side rudder bar assembly on CL–600– 2B19 aeroplanes. Laboratory examination of the fractured rudder pedal tubes found that in both cases, the fatigue cracks initiated at the aft taper pin holes where the connecting rod fitting is attached. Fatigue testing of the rudder pedal tubes confirmed that the fatigue cracking is due to loads induced during parking brake application. Therefore, only the rudder pedal tubes on the pilot’s side are vulnerable to fatigue cracking as the parking brake is primarily applied by the pilot. Loss of pilot rudder pedal input during flight would result in reduced yaw controllability of the aeroplane. Loss of pilot rudder pedal input during takeoff or landing may lead to a runway excursion. This [Canadian] AD mandates initial and repetitive [detailed visual or eddy current] inspections [for cracking] of both pilot-side rudder pedal tubes, part number (P/N) 600– 90204–3 until the terminating action in Part III of this [Canadian] AD is accomplished [i.e., replacement of both pilot-side rudder bar assemblies]. Corrective actions include replacement of both pilot-side rudder bar assemblies and repair. You may examine the MCAI in the AD docket on the Internet at https:// www.regulations.gov by searching for and locating Docket No. FAA–2017– 0907. Related Service Information Under 1 CFR Part 51 Bombardier, Inc., has issued the following service information. The service information describes procedures for repetitive inspections of the rudder pedal tubes for cracking, replacement of both pilot-side rudder bar assemblies, and repair. These documents are distinct since they apply to different airplane models.

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. 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 these same type designs. Costs of Compliance We estimate that this proposed AD affects 141 airplanes of U.S. registry. We estimate the following costs to comply with this proposed AD: ESTIMATED COSTS Action Labor cost Parts cost Inspections .......... 10 work-hours × $85 per hour = $850 per inspection cycle. Cost per product $0 Cost on U.S. operators $850 per inspection cycle $119,850 per inspection cycle. ON-CONDITION COSTS Action Labor cost Parts cost Replacement ....... 2 work-hours × $85 per hour = $170 ........................................................ Cost per product $8,564 Cost on U.S. operators $8,734 and Airworthiness Division, but during this transition period, the Executive Director has delegated the authority to issue ADs applicable to transport category airplanes to the Director of the System Oversight Division. The Proposed Amendment Authority for This Rulemaking rmajette on DSKBCKNHB2PROD with PROPOSALS We have received no definitive data that would enable us to provide cost estimates for any on-condition repairs specified in this proposed AD. We have no way of determining the number of aircraft that might need this repair. Regulatory Findings 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. This proposed AD is issued in accordance with authority delegated by the Executive Director, Aircraft Certification Service, as authorized by FAA Order 8000.51C. In accordance with that order, issuance of ADs is normally a function of the Compliance PART 39—AIRWORTHINESS DIRECTIVES 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. $1,231,494 VerDate Sep<11>2014 14:17 Oct 18, 2017 Jkt 244001 List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.

PO 00000 Frm 00004 Fmt 4702 Sfmt 4702 48671 Discussion We issued AD 2012–22–15, Amendment 39–17252 (77 FR 68063, November 15, 2012) (‘‘AD 2012–22– 15’’). AD 2012–22–15 requires actions intended to address an unsafe condition on all Fokker Services B.V. Model F28 Mark 0070 and Mark 0100 airplanes. We issued an NPRM to amend 14 CFR part 39 by adding an AD that would supersede AD 2012–22–15. The NPRM published in the Federal Register on December 16, 2016 (81 FR 91068). The NPRM was prompted by new and more restrictive airworthiness limitations. The NPRM proposed to revise the maintenance or inspection program, as applicable, to incorporate the new and more restrictive airworthiness limitations. Actions Since the NPRM Was Issued Since we issued the NPRM, additional airworthiness limitations have been issued and we have determined it is necessary to require revising the maintenance or inspection program, as applicable, to incorporate the new airworthiness limitations. The European Aviation Safety Agency (EASA), which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2017–0095, dated May 30, 2017 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Fokker Services B.V. Model F28 Mark 0070 and Mark 0100 airplanes. The MCAI states: Fokker Services Engineering Report SE– 623 contains the Airworthiness Limitation Items (ALIs) and Safe Life Items (SLIs). This report is Part 2 of the Airworthiness Limitations Section (ALS Part 2) of the Instructions for Continued Airworthiness, referred to in Section 06, Appendix 1, of the Fokker 70/100 Maintenance Review Board document. The complete ALS consists of: Part 1—Report SE–473, Certification Maintenance Requirements (CMRs)—ref. EASA AD 2015–0027 [which corresponds to FAA AD 2016–11–22, Amendment 39–18549 (81 FR 36438, June 7, 2016)], Part 2—Report SE–623, ALIs and SLIs—ref. EASA AD 2016–0125 [which corresponds to certain requirements in FAA AD 2012–22– 15], and Part 3—Report SE–672, Fuel ALIs and CDCCLs—ref. EASA AD 2015–0032 [which corresponds to FAA AD 2016–11–15, Amendment 39–18542 (81 FR 36447, June 7, 2016)]. The instructions contained in those reports have been identified as mandatory actions for continued airworthiness. Failure to accomplish these actions could result in an unsafe condition. EASA previously issued AD 2016–0125, requiring the actions described in ALS Part 2, Report SE–623 at issue 15 and 16. E:\FR\FM\19OCP1.SGM 19OCP1

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: We propose to adopt a new airworthiness directive (AD) for 
certain Bombardier, Inc., Model CL-600-1A11 (CL-600), CL-600-2A12 (CL-
601 Variant), and CL-600-2B16 (CL-601-3A, CL-601-3R, and CL-604 
Variants) airplanes. This proposed AD was prompted by reports of 
fractured rudder pedal tubes on the pilot-side rudder bar assembly. 
This proposed AD would require repetitive inspections of the rudder 
pedal tubes for cracking and corrective actions if necessary. 
Replacement of both pilot-side rudder bar assemblies is terminating 
action for the inspections. We are proposing this AD to address the 
unsafe condition on these products.

DATES: We must receive comments on this proposed AD by December 4, 
2017.

Discussion

    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2017-09, dated February 22, 2017 (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-
1A11 (CL-600), CL-600-2A12 (CL-601 Variant), and CL-600-2B16 (CL-601-
3A, CL-601-3R, and CL-604 Variants) airplanes. The MCAI states:

    There have been two in-service reports of fractured rudder pedal 
tubes installed on the pilot-side rudder bar assembly on CL-600-2B19 
aeroplanes. Laboratory examination of the fractured rudder pedal 
tubes found that in both cases, the fatigue cracks initiated at the 
aft taper pin holes where the connecting rod fitting is attached. 
Fatigue testing of the rudder pedal tubes confirmed that the fatigue 
cracking is due to loads induced during parking brake application. 
Therefore, only the rudder pedal tubes on the pilot's side are 
vulnerable to fatigue cracking as the parking brake is primarily 
applied by the pilot.
    Loss of pilot rudder pedal input during flight would result in 
reduced yaw controllability of the aeroplane. Loss of pilot rudder 
pedal input during takeoff or landing may lead to a runway 
excursion.
    This [Canadian] AD mandates initial and repetitive [detailed 
visual or eddy current] inspections [for cracking] of both pilot-
side rudder pedal tubes, part number (P/N) 600-90204-3 until the 
terminating action in Part III of this [Canadian] AD is accomplished 
[i.e., replacement of both pilot-side rudder bar assemblies].

    Corrective actions include replacement of both pilot-side rudder 
bar assemblies and repair. You may examine the MCAI in the AD docket on 
the Internet at https://www.regulations.gov by searching for and 
locating Docket No. FAA-2017-0907.

Related Service Information Under 1 CFR Part 51

    Bombardier, Inc., has issued the following service information. The 
service information describes procedures for repetitive inspections of 
the rudder pedal tubes for cracking, replacement of both pilot-side 
rudder bar assemblies, and repair. These documents are distinct since 
they apply to different airplane models.

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 these 
same type designs.

Costs of Compliance

    We estimate that this proposed AD affects 141 airplanes of U.S. 
registry.
    We estimate the following costs to comply with this proposed AD:

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

    We have received no definitive data that would enable us to provide 
cost estimates for any on-condition repairs specified in this proposed 
AD. We have no way of determining the number of aircraft that might 
need this repair.

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.
    This proposed AD is issued in accordance with authority delegated 
by the Executive Director, Aircraft Certification Service, as 
authorized by FAA Order 8000.51C. In accordance with that order, 
issuance of ADs is normally a function of the Compliance and 
Airworthiness Division, but during this transition period, the 
Executive Director has delegated the authority to issue ADs applicable 
to transport category airplanes to the Director of the System Oversight 
Division.

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.

excursion.

(f) Compliance

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

(g) Repetitive Inspections and Part Marking

    At the applicable time specified in figure 1 to paragraph (g) of 
this AD, do a detailed or eddy current inspection of both pilot-side 
rudder pedal tubes for cracking, in accordance with Part A of the 
Accomplishment Instructions of the applicable service information 
identified in paragraphs (g)(1) through (g)(6) of this AD. If no 
cracking is found, before further flight, mark the part in 
accordance with Part A of the Accomplishment Instructions of the 
applicable service information identified in paragraphs (g)(1) 
through (g)(6) of this AD. Repeat the detailed or eddy current 
inspection thereafter at intervals not to exceed 600 flight cycles
