SUPPLEMENTARY INFORMATION: Discussion Transport Canada Civil Aviation (TCCA), which is the aviation authority E:\FR\FM\16DER1.SGM 16DER1 90962 Federal Register / Vol. 81, No. 242 / Friday, December 16, 2016 / Rules and Regulations for Canada, has issued Canadian AD CF–2016–23, dated July 28, 2016 (referred to after this as the Mandatory Continuing Airworthiness Information, or ‘‘the MCAI’’), to correct an unsafe condition for certain Bombardier, Inc. Model BD–700–1A10 and BD–700– 1A11 airplanes. The MCAI states: Bombardier reported that during maintenance of a BD–700 aeroplane, the engine mount pin, part number (P/N) BRR15838, was found backed out of the rear mount link. The retaining bolt, P/N AS54020, which passes through the engine mount pin was also found fractured at the groove which holds the locking spring. An investigation revealed the most probable root cause of failure to be a single axial tension static overload, with no evidence of fatigue contributing to the failure. The above condition if not detected, may result in the loss of engine attachment to the airframe. Bombardier has issued Service Bulletins (SBs) 700–71–002, 700–71–6002, 700–71– 5002 and 700–1A11–71–002 to inspect the attachment points of the links between the engine rear mount assemblies, and installation of replacement hardware if required. This [Canadian] AD mandates incorporation of the above Bombardier SBs to inspect [for discrepancies (including missing or broken bolts, missing nuts, incorrect torque values, and an incorrect gap between the bushing and washer), noncompliant gaps and torque values, broken or missing attachment hardware; and corrective actions, including installation of replacement hardware if necessary] and maintain integrity of the affected engine rear mount assembly. Bombardier is developing design changes for the parts in question. Further mandatory action may be required when the new parts become available. You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA–2016–9503. Related Service Information Under 1 CFR Part 51 FAA’s Determination of the Effective Date We reviewed the following service information: • Bombardier Service Bulletin 700– 71–002, Revision 01, dated June 30, 2016. • Bombardier Service Bulletin 700– 71–6002, Revision 01, dated June 30, 2016. • Bombardier Service Bulletin 700– 71–5002, Revision 01, dated June 30, 2016. • Bombardier Service Bulletin 700– 1A11–71–002, Revision 01, dated June 30, 2016. The service information describes procedures for an inspection for discrepancies of the attachment points of the links between the engine rear mount assemblies, and corrective actions. These documents are distinct since they apply to different airplane models and serial numbers. 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. An unsafe condition exists that requires the immediate adoption of this AD. The FAA has found that the risk to the flying public justifies waiving notice and comment prior to adoption of this rule because broken engine attachment hardware could result in separation of an engine from the airplane. Therefore, we determined that notice and opportunity for public comment before issuing this AD are impracticable and that good cause exists for making this amendment effective in fewer than 30 days. FAA’s Determination and Requirements of This 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 issuing this AD because we evaluated all pertinent information and determined the unsafe condition exists and is likely to exist or develop on other products of these same type designs. Comments Invited This AD is a final rule that involves requirements affecting flight safety, and we did not precede it by notice and opportunity for public comment. We invite you to send any written relevant data, views, or arguments about this AD. Send your comments to an address listed under the ADDRESSES section. Include ‘‘Docket No. FAA–2016–9503; Directorate Identifier 2016–NM–179– AD’’ at the beginning of your comments. We specifically invite comments on the overall regulatory, economic, environmental, and energy aspects of this AD. We will consider all comments received by the closing date and may amend this AD based on those comments. We will post all comments we receive, without change, to http:// www.regulations.gov, including any personal information you provide. We will also post a report summarizing each substantive verbal contact we receive about this AD. Costs of Compliance We estimate that this AD affects 97 airplanes of U.S. registry. We estimate the following costs to comply with this AD: ESTIMATED COSTS Labor cost Inspection ........................................................ asabaliauskas on DSK3SPTVN1PROD with RULES Action 1 work-hour × $85 per hour = $85 per airplane. We estimate the following costs to do any necessary corrective actions that would be required based on the results of the inspection. We have no way of Cost per product Parts cost $0 $85 Cost on U.S. operators $8,245 determining the number of aircraft that might need these corrective actions: ON-CONDITION COSTS Action Labor cost Bolt and Nut Replacement ........................................... 1 work-hour × $85 per hour = $85 ...............................

We have received no definitive data that would enable us to provide cost estimates for other on-condition actions specified in this AD. According to the manufacturer, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected individuals. We do not control warranty coverage for affected individuals. As a result, we have included all available costs in our cost estimate. 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 DSK3SPTVN1PROD with RULES 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 VerDate Sep<11>2014 17:15 Dec 15, 2016 Jkt 241001 under the criteria of the Regulatory Flexibility Act.

Airworthiness Directives; Bombardier, Inc. Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

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

SUMMARY: We are adopting a new airworthiness directive (AD) for certain 
Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. This AD 
requires an inspection for discrepancies of the attachment points of 
the links between the engine rear mount assemblies, and corrective 
actions if necessary. This AD was prompted by a report indicating that 
during maintenance, an engine mount pin was found backed out of the 
rear mount link, and the associated retaining bolt was also found 
fractured. We are issuing this AD to address the unsafe condition on 
these products.

DATES: This AD becomes effective January 3, 2017.

SUPPLEMENTARY INFORMATION: 

Discussion

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

[[Page 90962]]

for Canada, has issued Canadian AD CF-2016-23, dated July 28, 2016 
(referred to after this as the Mandatory Continuing Airworthiness 
Information, or ``the MCAI''), to correct an unsafe condition for 
certain Bombardier, Inc. Model BD-700-1A10 and BD-700-1A11 airplanes. 
The MCAI states:

    Bombardier reported that during maintenance of a BD-700 
aeroplane, the engine mount pin, part number (P/N) BRR15838, was 
found backed out of the rear mount link. The retaining bolt, P/N 
AS54020, which passes through the engine mount pin was also found 
fractured at the groove which holds the locking spring. An 
investigation revealed the most probable root cause of failure to be 
a single axial tension static overload, with no evidence of fatigue 
contributing to the failure.
    The above condition if not detected, may result in the loss of 
engine attachment to the airframe.
    Bombardier has issued Service Bulletins (SBs) 700-71-002, 700-
71-6002, 700-71-5002 and 700-1A11-71-002 to inspect the attachment 
points of the links between the engine rear mount assemblies, and 
installation of replacement hardware if required.
    This [Canadian] AD mandates incorporation of the above 
Bombardier SBs to inspect [for discrepancies (including missing or 
broken bolts, missing nuts, incorrect torque values, and an 
incorrect gap between the bushing and washer), noncompliant gaps and 
torque values, broken or missing attachment hardware; and corrective 
actions, including installation of replacement hardware if 
necessary] and maintain integrity of the affected engine rear mount 
assembly. Bombardier is developing design changes for the parts in 
question. Further mandatory action may be required when the new 
parts become available.

    You may examine the MCAI on the Internet at http://www.regulations.gov by searching for and locating Docket No. FAA-2016-
9503.

Related Service Information Under 1 CFR Part 51

    We reviewed the following service information:
     Bombardier Service Bulletin 700-71-002, Revision 01, dated 
June 30, 2016.
     Bombardier Service Bulletin 700-71-6002, Revision 01, 
dated June 30, 2016.
     Bombardier Service Bulletin 700-71-5002, Revision 01, 
dated June 30, 2016.
     Bombardier Service Bulletin 700-1A11-71-002, Revision 01, 
dated June 30, 2016.
    The service information describes procedures for an inspection for 
discrepancies of the attachment points of the links between the engine 
rear mount assemblies, and corrective actions. These documents are 
distinct since they apply to different airplane models and serial 
numbers. 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 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 issuing this AD because we 
evaluated all pertinent information and determined the unsafe condition 
exists and is likely to exist or develop on other products of these 
same type designs.

FAA's Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD. The FAA has found that the risk to the flying public justifies 
waiving notice and comment prior to adoption of this rule because 
broken engine attachment hardware could result in separation of an 
engine from the airplane. Therefore, we determined that notice and 
opportunity for public comment before issuing this AD are impracticable 
and that good cause exists for making this amendment effective in fewer 
than 30 days.

Comments Invited

    This AD is a final rule that involves requirements affecting flight 
safety, and we did not precede it by notice and opportunity for public 
comment. We invite you to send any written relevant data, views, or 
arguments about this AD. Send your comments to an address listed under 
the ADDRESSES section. Include ``Docket No. FAA-2016-9503; Directorate 
Identifier 2016-NM-179-AD'' at the beginning of your comments. We 
specifically invite comments on the overall regulatory, economic, 
environmental, and energy aspects of this AD. We will consider all 
comments received by the closing date and may amend this AD based on 
those comments.
    We will post all comments we receive, without change, to http://www.regulations.gov, including any personal information you provide. We 
will also post a report summarizing each substantive verbal contact we 
receive about this AD.

Costs of Compliance

    We estimate that this AD affects 97 airplanes of U.S. registry.
    We estimate the following costs to comply with this AD:

                                                 Estimated Costs
----------------------------------------------------------------------------------------------------------------
                                                                                     Cost per      Cost on U.S.
                Action                         Labor cost           Parts cost        product        operators
----------------------------------------------------------------------------------------------------------------
Inspection............................  1 work-hour x $85 per                 $0             $85          $8,245
                                         hour = $85 per airplane.
----------------------------------------------------------------------------------------------------------------

    We estimate the following costs to do any necessary corrective 
actions 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 corrective actions:

                                               On-Condition Costs
----------------------------------------------------------------------------------------------------------------
                                                                                                     Cost per
                    Action                                 Labor cost               Parts cost        product
----------------------------------------------------------------------------------------------------------------
Bolt and Nut Replacement......................  1 work-hour x $85 per hour = $85            $730            $815

[[Page 90963]]

 
Torque Change on Affected Bolts...............  1 work-hour x $85 per hour = $85               0              85
----------------------------------------------------------------------------------------------------------------

    We have received no definitive data that would enable us to provide 
cost estimates for other on-condition actions specified in this AD.
    According to the manufacturer, some of the costs of this AD may be 
covered under warranty, thereby reducing the cost impact on affected 
individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all available costs in our 
cost estimate.

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.
