ACTION: Final rule. AGENCY: We are superseding Airworthiness Directive (AD) 2014–16– 02, which applied to certain Bombardier, Inc., Model CL–600–1A11 (CL–600) airplanes. AD 2014–16–02 required revising the airplane flight manual to prohibit thrust reverser operation, doing repetitive detailed inspections of both engine thrust reversers for cracks, and modifying the thrust reversers if necessary. The modification is also an interim (optional) terminating action for the repetitive inspections. This new AD adds a new terminating modification of the thrust reversers, which includes new inspections and repair, if necessary. This AD was prompted by a determination that it is necessary to add a requirement to repair or modify the thrust reversers, which would terminate the requirements of AD 2014–16–02. We are issuing this AD to address the unsafe condition on these products. DATES: This AD is effective August 3, 2017. The Director of the Federal Register approved the incorporation by reference of certain publications listed in this AD as of August 3, 2017. The Director of the Federal Register approved the incorporation by reference of certain other publications listed in this AD as of August 12, 2014 (79 FR 46968, August 12, 2014).

SUPPLEMENTARY INFORMATION: Discussion We issued a supplemental notice of proposed rulemaking (SNPRM) to amend 14 CFR part 39 to supersede AD 2014–16–02, Amendment 39–17926 (79 FR 46968, August 12, 2014) (‘‘AD 2014– 16–02’’). AD 2014–16–02 applied to certain Bombardier, Inc. Model CL–600– 1A11 (CL–600) airplanes. The SNPRM published in the Federal Register on December 13, 2016 (81 FR 89881) (‘‘the SNPRM’’). We preceded the SNPRM with a notice of proposed rulemaking (NPRM) that published in the Federal Register on December 24, 2015 (80 FR 80293) (‘‘the NPRM’’). The NPRM was prompted by a determination that it is necessary to add a requirement to repair or modify the thrust reversers, which would terminate the requirements of AD 2014–16–02 after modification or repair. The NPRM proposed to continue to require the actions specified in AD 2014–16–02 until modification or repair of the thrust reversers. The SNPRM proposed to reduce the compliance time for modification of the thrust reversers, and add new modification procedures. We are issuing this AD to detect and correct cracks of the translating sleeve at the thrust reverser actuator attachment points, which could result in PO 00000 Frm 00014 Fmt 4700 Sfmt 4700 deployment or dislodgement of an engine thrust reverser in flight and subsequent reduced control of the airplane. Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2014–19R1, dated March 11, 2016 (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) airplanes. The MCAI states: There have been two reported incidents of partial deployment of an engine thrust reverser in-flight, caused by a failure of the translating sleeve at the thrust reverser actuator attachment points. Inspection of the same area on some other thrust reversers revealed cracks emanating from the holes under the nut plates. In both incidents, the affected aeroplane landed safely without any noticeable controllability issues, however structural failure of thrust reverser actuator attachment points resulting in thrust reverser deployment or dislodgment in flight is a safety hazard warranting an immediate mitigating action. To help in mitigating any immediate safety hazard, Bombardier Inc. has revised the Aircraft Flight Manual (AFM) through Temporary Revisions (TR) 600/29, 600/30, 600–1/24 and 600–1/26, to prohibit the thrust reverser operation on affected aeroplanes. Additionally, as an interim corrective action, Bombardier Inc. has issued alert service bulletin (ASB) A600–0769 requiring an inspection and/or a mechanical lock out of the thrust reverser to prevent it from moving out of forward thrust mode. Original [TCCA] Emergency AD CF–2014– 19 [which corresponds to FAA AD 2014–16– 02] was issued 20 June 2014 to mandate the incorporation of above mentioned revised AFM procedures and compliance with ASB A600–0769. This [TCCA] AD is now being revised to include the terminating action [modification of the thrust reversers] in accordance with Part C of the ASB A600– 0769 Rev 02 dated 22 February 2016. 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– 7529. Comments We gave the public the opportunity to participate in developing this AD. We received no comments on the SNPRM or on the determination of the cost to the public. Conclusion We reviewed the available data and determined that air safety and the public interest require adopting this AD as proposed, except for minor editorial E:\FR\FM\29JNR1.SGM 29JNR1 29377 Federal Register / Vol. 82, No. 124 / Thursday, June 29, 2017 / Rules and Regulations changes. We have determined that these minor changes: • Are consistent with the intent that was proposed in the SNPRM for correcting the unsafe condition; and • Do not add any additional burden upon the public than was already proposed in the SNPRM. Related Service Information Under 1 CFR Part 51 We reviewed Bombardier Alert Service Bulletin A600–0769, Revision 02, dated February 22, 2016. The service information describes procedures for a new permanent modification of the thrust reversers on both engines, which includes inspections for cracks and elongated holes. We also reviewed the following TRs, which introduce procedures to prohibit thrust reverser operation. These documents are distinct since they apply to different airplane configurations. • Canadair TR 600/29–2, dated January 18, 2016, to the Canadair CL– 600–1A11 AFM. • Canadair TR 600–1/24–2, dated January 18, 2016, to the Canadair CL– 600–1A11 AFM (Winglets). 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. Costs of Compliance We estimate that this AD affects 18 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Cost per product Labor cost AFM revision; inspection [retained actions from AD 2014-16-02]. New modification ............................................. 29 work-hours × $85 per hour = $2,465 ........ N/A $2,465 $44,370 100 work-hours × $85 per hour = $8,500 ...... $509 9,009 162,162 We estimate the following costs to do any necessary modifications that will be Parts cost Cost on U.S. operators Action required based on the results of the inspection. We have no way of determining the number of aircraft that might need this modification: ON-CONDITION COSTS Action Labor cost Modification ...................................... 36 work-hours × $85 per hour = $3,060 ................................................... nlaroche on DSK30NT082PROD with RULES We have received no definitive data that would enable us to provide cost estimates for the on-condition actions for the inspections that are part of the new modification specified in 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 VerDate Sep<11>2014 15:31 Jun 28, 2017 Jkt 241001 Parts cost 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.

SUPPLEMENTARY INFORMATION: FOR FURTHER INFORMATION CONTACT: Authority for This Rulemaking The FAA’s authority to issue rules regarding aviation safety is found in Title 49 of the United States Code. 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. This rulemaking is promulgated under the authority described in Subtitle VII, Part A, Subpart I, Section 40103. Under that section, the FAA is charged with prescribing regulations to assign the use of airspace necessary to ensure the safety of aircraft and the efficient use of airspace. This regulation is within the scope of that authority as it establishes Class E airspace extending upward from 700 feet above the surface at Finleyville Airpark, Finleyville, PA to support instrument flight rules (IFR) operations at the airport.

Airworthiness Directives; Bombardier, Inc., Airplanes

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

ACTION: Final rule.

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

SUMMARY: We are superseding Airworthiness Directive (AD) 2014-16-02, 
which applied to certain Bombardier, Inc., Model CL-600-1A11 (CL-600) 
airplanes. AD 2014-16-02 required revising the airplane flight manual 
to prohibit thrust reverser operation, doing repetitive detailed 
inspections of both engine thrust reversers for cracks, and modifying 
the thrust reversers if necessary. The modification is also an interim 
(optional) terminating action for the repetitive inspections. This new 
AD adds a new terminating modification of the thrust reversers, which 
includes new inspections and repair, if necessary. This AD was prompted 
by a determination that it is necessary to add a requirement to repair 
or modify the thrust reversers, which would terminate the requirements 
of AD 2014-16-02. We are issuing this AD to address the unsafe 
condition on these products.

DATES: This AD is effective August 3, 2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain publications listed in this AD as of August 3, 
2017.
    The Director of the Federal Register approved the incorporation by 
reference of certain other publications listed in this AD as of August 
12, 2014 (79 FR 46968, August 12, 2014).

SUPPLEMENTARY INFORMATION:

Discussion

    We issued a supplemental notice of proposed rulemaking (SNPRM) to 
amend 14 CFR part 39 to supersede AD 2014-16-02, Amendment 39-17926 (79 
FR 46968, August 12, 2014) (``AD 2014-16-02''). AD 2014-16-02 applied 
to certain Bombardier, Inc. Model CL-600-1A11 (CL-600) airplanes. The 
SNPRM published in the Federal Register on December 13, 2016 (81 FR 
89881) (``the SNPRM''). We preceded the SNPRM with a notice of proposed 
rulemaking (NPRM) that published in the Federal Register on December 
24, 2015 (80 FR 80293) (``the NPRM''). The NPRM was prompted by a 
determination that it is necessary to add a requirement to repair or 
modify the thrust reversers, which would terminate the requirements of 
AD 2014-16-02 after modification or repair. The NPRM proposed to 
continue to require the actions specified in AD 2014-16-02 until 
modification or repair of the thrust reversers. The SNPRM proposed to 
reduce the compliance time for modification of the thrust reversers, 
and add new modification procedures. We are issuing this AD to detect 
and correct cracks of the translating sleeve at the thrust reverser 
actuator attachment points, which could result in deployment or 
dislodgement of an engine thrust reverser in flight and subsequent 
reduced control of the airplane.
    Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2014-19R1, dated March 11, 2016 (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) airplanes. The MCAI states:

    There have been two reported incidents of partial deployment of 
an engine thrust reverser in-flight, caused by a failure of the 
translating sleeve at the thrust reverser actuator attachment 
points. Inspection of the same area on some other thrust reversers 
revealed cracks emanating from the holes under the nut plates.
    In both incidents, the affected aeroplane landed safely without 
any noticeable controllability issues, however structural failure of 
thrust reverser actuator attachment points resulting in thrust 
reverser deployment or dislodgment in flight is a safety hazard 
warranting an immediate mitigating action.
    To help in mitigating any immediate safety hazard, Bombardier 
Inc. has revised the Aircraft Flight Manual (AFM) through Temporary 
Revisions (TR) 600/29, 600/30, 600-1/24 and 600-1/26, to prohibit 
the thrust reverser operation on affected aeroplanes. Additionally, 
as an interim corrective action, Bombardier Inc. has issued alert 
service bulletin (ASB) A600-0769 requiring an inspection and/or a 
mechanical lock out of the thrust reverser to prevent it from moving 
out of forward thrust mode.
    Original [TCCA] Emergency AD CF-2014-19 [which corresponds to 
FAA AD 2014-16-02] was issued 20 June 2014 to mandate the 
incorporation of above mentioned revised AFM procedures and 
compliance with ASB A600-0769. This [TCCA] AD is now being revised 
to include the terminating action [modification of the thrust 
reversers] in accordance with Part C of the ASB A600-0769 Rev 02 
dated 22 February 2016.

    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-
7529.

Comments

    We gave the public the opportunity to participate in developing 
this AD. We received no comments on the SNPRM or on the determination 
of the cost to the public.

Conclusion

    We reviewed the available data and determined that air safety and 
the public interest require adopting this AD as proposed, except for 
minor editorial

[[Page 29377]]

changes. We have determined that these minor changes:
     Are consistent with the intent that was proposed in the 
SNPRM for correcting the unsafe condition; and
     Do not add any additional burden upon the public than was 
already proposed in the SNPRM.

Related Service Information Under 1 CFR Part 51

    We reviewed Bombardier Alert Service Bulletin A600-0769, Revision 
02, dated February 22, 2016. The service information describes 
procedures for a new permanent modification of the thrust reversers on 
both engines, which includes inspections for cracks and elongated 
holes.
    We also reviewed the following TRs, which introduce procedures to 
prohibit thrust reverser operation. These documents are distinct since 
they apply to different airplane configurations.
     Canadair TR 600/29-2, dated January 18, 2016, to the 
Canadair CL-600-1A11 AFM.
     Canadair TR 600-1/24-2, dated January 18, 2016, to the 
Canadair CL-600-1A11 AFM (Winglets).
    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.

Costs of Compliance

    We estimate that this AD affects 18 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.

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

    We estimate the following costs to do any necessary modifications 
that will be required based on the results of the inspection. We have 
no way of determining the number of aircraft that might need this 
modification:

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

    We have received no definitive data that would enable us to provide 
cost estimates for the on-condition actions for the inspections that 
are part of the new modification specified in 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 
of the Regulatory Flexibility Act.
