We will also post a report summarizing each substantive verbal contact we receive about this proposed AD. Discussion asabaliauskas on DSKBBXCHB2PROD with PROPOSALS On May 17, 2016, we issued AD 2016–11–02, Amendment 39–18529 (81 FR 33371, May 26, 2016) (‘‘AD 2016– 11–02’’), for all Bombardier, Inc., Model CL–600–2C10 (Regional Jet Series 700, 701, & 702) airplanes; Model CL–600– 2D15 (Regional Jet Series 705) airplanes; Model CL–600–2D24 (Regional Jet Series 900) airplanes; and Model CL– 600–2E25 (Regional Jet Series 1000) airplanes. AD 2016–11–02 was prompted by reports of loose or missing fasteners on the upper and lower engine pylon structure common to the upper and lower pylon skin panels and engine thrust fitting. AD 2016–11–02 requires repetitive detailed visual inspections of the upper and lower engine pylons for protruding, loose, or missing fasteners; and repair, including applicable related investigative and corrective actions, if necessary. We issued AD 2016–11–02 to detect and correct protruding, loose, or missing fasteners, which could result in structural failure of the engine pylons. Since we issued AD 2016–11–02, we have determined that a terminating action is necessary to address the unsafe condition. In addition, Transport Canada Civil Aviation (TCCA), which is the aviation authority for Canada, has issued Canadian Airworthiness Directive CF–2016–10R1, dated July 8, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for all Bombardier, Inc., Model CL–600–2C10 (Regional Jet Series 700, 701, & 702) airplanes; Model CL–600–2D15 (Regional Jet Series 705) airplanes; Model CL–600–2D24 (Regional Jet Series 900) airplanes; and Model CL–600–2E25 (Regional Jet Series 1000) airplanes. The MCAI states: There have been several reported findings of loose or missing Hi-Lite fasteners and collars on the left hand (L/H) and right hand (R/H) upper and lower engine pylon structure common to the upper and lower pylon skin panels and engine thrust fitting. Missing fasteners in these areas are shown to significantly reduce the safety margins and could result in a structural failure of the engine pylon. Bombardier, as an interim corrective action issued a new Aircraft Maintenance Manual (AMM) task for detailed inspection of the engine pylon rib and skin fasteners to inspect for protruding, loose or missing fasteners and rectify any discrepancies noted in accordance with a Repair Engineering Order (REO). The original version of this [Canadian] AD, CF– 2016–10, mandated the subject inspection and necessary rectification. Bombardier has since issued Service Bulletin (SB) 670BA–54–007 to replace all affected fasteners with interference fit fasteners [including applicable related investigative and corrective actions], as terminating action for the mandated inspection requirement. [Canadian] AD CF– 2016–10 is now being revised to mandate compliance with SB 670BA–54–007. Related investigative actions include measurements of the attach holes in the engine pylon upper structure and special detailed visual inspections for cracks in the engine pylon structure. Corrective actions include repair. You may examine the MCAI in the AD docket on the Internet at https:// 26865 www.regulations.gov by searching for and locating Docket No. FAA–2017– 0530. Related Service Information Under 1 CFR Part 51 Bombardier, Inc., issued Service Bulletin 670BA–54–007, dated May 13, 2016. The service information describes procedures for replacing fasteners and collars, including applicable related investigative and corrective actions. Bombardier, Inc., also issued Repair Engineering Order 670–54–51–034, ‘‘Repair for Missing or Loose/Protruding Fasteners in Upper and Lower Pylon Skins FS 1088–FS 1098, PBL 69.3 L & RHS,’’ Revision A, dated April 20, 2016. The service information describes procedures for repair, including applicable related investigative and corrective actions. In addition, Bombardier, Inc., issued Temporary Revision 54–0007, dated March 8, 2016, to the CRJ700/900/1000 AMM. The service information describes procedures for a detailed visual inspection for protruding, loose, or missing fasteners of the left-hand and right-hand upper and lower engine pylons. 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 273 airplanes of U.S. registry. ESTIMATED COSTS Action Labor cost Inspection (retained from AD 2016–11–02).

Cost per product Parts cost (1) Up to $2,720. 1 We have received no definitive data that would enable us to provide cost estimates for the parts cost specified in this proposed AD for the on-condition repairs. 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. asabaliauskas on DSKBBXCHB2PROD with PROPOSALS 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.

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

SUMMARY: We propose to supersede Airworthiness Directive (AD) 2016-11-
02, which applies to all Bombardier, Inc., Model CL-600-2C10 (Regional 
Jet Series 700, 701, & 702) airplanes; Model CL-600-2D15 (Regional Jet 
Series 705) airplanes; Model CL-600-2D24 (Regional Jet Series 900) 
airplanes; and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. 
AD 2016-11-02 requires repetitive inspections of the upper and lower 
engine pylons for protruding, loose, or missing fasteners; and repair 
if necessary. Since we issued AD 2016-11-02, we have determined that a 
terminating action is necessary to address the unsafe condition. This 
proposed AD would continue to require the repetitive inspections of the 
upper and lower engine pylons for protruding, loose, or missing 
fasteners; and repair if necessary. This proposed AD would also require 
replacement of affected fasteners, which terminates the inspections. We 
are proposing this AD to address the unsafe condition on these 
products.

Discussion

    On May 17, 2016, we issued AD 2016-11-02, Amendment 39-18529 (81 FR 
33371, May 26, 2016) (``AD 2016-11-02''), for all Bombardier, Inc., 
Model CL-600-2C10 (Regional Jet Series 700, 701, & 702) airplanes; 
Model CL-600-2D15 (Regional Jet Series 705) airplanes; Model CL-600-
2D24 (Regional Jet Series 900) airplanes; and Model CL-600-2E25 
(Regional Jet Series 1000) airplanes. AD 2016-11-02 was prompted by 
reports of loose or missing fasteners on the upper and lower engine 
pylon structure common to the upper and lower pylon skin panels and 
engine thrust fitting. AD 2016-11-02 requires repetitive detailed 
visual inspections of the upper and lower engine pylons for protruding, 
loose, or missing fasteners; and repair, including applicable related 
investigative and corrective actions, if necessary. We issued AD 2016-
11-02 to detect and correct protruding, loose, or missing fasteners, 
which could result in structural failure of the engine pylons.
    Since we issued AD 2016-11-02, we have determined that a 
terminating action is necessary to address the unsafe condition. In 
addition, Transport Canada Civil Aviation (TCCA), which is the aviation 
authority for Canada, has issued Canadian Airworthiness Directive CF-
2016-10R1, dated July 8, 2016 (referred to after this as the Mandatory 
Continuing Airworthiness Information, or ``the MCAI''), to correct an 
unsafe condition for all Bombardier, Inc., Model CL-600-2C10 (Regional 
Jet Series 700, 701, & 702) airplanes; Model CL-600-2D15 (Regional Jet 
Series 705) airplanes; Model CL-600-2D24 (Regional Jet Series 900) 
airplanes; and Model CL-600-2E25 (Regional Jet Series 1000) airplanes. 
The MCAI states:

    There have been several reported findings of loose or missing 
Hi-Lite fasteners and collars on the left hand (L/H) and right hand 
(R/H) upper and lower engine pylon structure common to the upper and 
lower pylon skin panels and engine thrust fitting. Missing fasteners 
in these areas are shown to significantly reduce the safety margins 
and could result in a structural failure of the engine pylon.
    Bombardier, as an interim corrective action issued a new 
Aircraft Maintenance Manual (AMM) task for detailed inspection of 
the engine pylon rib and skin fasteners to inspect for protruding, 
loose or missing fasteners and rectify any discrepancies noted in 
accordance with a Repair Engineering Order (REO). The original 
version of this [Canadian] AD, CF-2016-10, mandated the subject 
inspection and necessary rectification.
    Bombardier has since issued Service Bulletin (SB) 670BA-54-007 
to replace all affected fasteners with interference fit fasteners 
[including applicable related investigative and corrective actions], 
as terminating action for the mandated inspection requirement. 
[Canadian] AD CF-2016-10 is now being revised to mandate compliance 
with SB 670BA-54-007.

Related investigative actions include measurements of the attach holes 
in the engine pylon upper structure and special detailed visual 
inspections for cracks in the engine pylon structure. Corrective 
actions include 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-2017-0530.

Related Service Information Under 1 CFR Part 51

    Bombardier, Inc., issued Service Bulletin 670BA-54-007, dated May 
13, 2016. The service information describes procedures for replacing 
fasteners and collars, including applicable related investigative and 
corrective actions.
    Bombardier, Inc., also issued Repair Engineering Order 670-54-51-
034, ``Repair for Missing or Loose/Protruding Fasteners in Upper and 
Lower Pylon Skins FS 1088-FS 1098, PBL 69.3 L & RHS,'' Revision A, 
dated April 20, 2016. The service information describes procedures for

    In addition, Bombardier, Inc., issued Temporary Revision 54-0007, 
dated March 8, 2016, to the CRJ700/900/1000 AMM. The service 
information describes procedures for a detailed visual inspection for 
protruding, loose, or missing fasteners of the left-hand and right-hand 
upper and lower engine pylons.
    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 273 airplanes of U.S. 
registry.

[[Page 26866]]

    We estimate the following costs to do any necessary repairs that 
would be required based on the results of the inspection. We have no 
way of determining the number of aircraft that might need these 
repairs:

                                               On-Condition Costs

----------------------------------------------------------------------------------------------------------------
\1\ We have received no definitive data that would enable us to provide cost estimates for the parts cost
  specified in this proposed AD for the on-condition repairs.

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.

List of Subjects in 14 CFR Part 39

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

The Proposed Amendment

    Accordingly, under the authority delegated to me by the
