Discussion EASA, which is the Technical Agent for the Member States of the European Union, has issued Emergency AD No. 2017–0232–E, dated November 21, 2017, to correct an unsafe condition for Airbus Helicopters Model AS 332 C, AS 332 C1, AS 332 L, and AS 332 L1 helicopters. The EASA AD was prompted by the in-flight failure of a pin in a hinge attaching the T/R. EASA advises that damage to the hinge on a T/R blade was reported and that an investigation is ongoing to determine the root cause of the damage. EASA further advises that this condition could lead to failure of the hinge, unbalance of the T/R, and detachment of the T/R gearbox and hub with subsequent loss of control of the helicopter. To correct this unsafe condition, the EASA AD requires a one-time inspection of the flapping hinges, and depending on the findings, corrective actions. It also requires reporting the findings and sending any cracked components to Airbus Helicopters to support the investigation. FAA’s Determination These helicopters have been approved by the aviation authority of France and are approved for operation in the United States. Pursuant to our bilateral agreement with France, EASA, its technical representative, has notified us of the unsafe condition described in the EASA AD. We are issuing this AD because we evaluated all information provided by EASA and determined the unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs. Related Service Information Under 1 CFR Part 51 We reviewed Airbus Helicopters Emergency Alert Service Bulletin PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 10361 (EASB) No. 64.00.43, Revision 0, dated November 21, 2017, for Model AS332series helicopters. This service information describes procedures for visually and dye penetrant inspecting the hinges of all five T/Rs. 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. AD Requirements This AD requires, within 25 hours time-in-service (TIS): • Performing a tactile inspection of each hinge for friction points; • Measuring for play in the drag plane; • Measuring the tightening torque of each spindle bolt. Æ If the tightening torque is not within the minimum and maximum torque, dye-penetrant inspecting the spindle bolt for a crack and removing the spindle bolt and hexagonal castellated nut from service; Æ If the tightening torque is within the minimum and maximum torque, inspecting the spindle bolt for corrosion and fretting. • Inspecting the bearing race inner ring and bearing needles for spalling and replacing the bearing race if there is any spalling; • Measuring the thickness of each stop washer and removing the stop washer from service if the thickness is less than 1.5 mm (.060 inch); and • Inspecting the inner ring for brinelling. Æ If there is brinelling deeper than 0.1 mm (.004 inch), repairing the hinge. Æ If there is brinelling 0.1 mm (.004 inch) or less, dye-penetrant inspecting the inner ring for a crack. This AD also requires, within 10 days after the inspection, reporting the results of each inspection and measurement to Airbus Helicopters. Differences Between This AD and the EASA AD The EASA AD requires compliance within 25 hours TIS or at the next 50 hour inspection of the T/R, whichever is later; this AD requires compliance within 25 hours TIS. The EASA AD requires returning parts to Airbus Helicopters, and this AD does not. Interim Action We considered this AD interim action. The inspection reports that are required by this AD will enable Airbus Helicopters to obtain better insight into the cause of the damaged flapping hinge link, and eventually develop final action to address the unsafe condition. Once E:\FR\FM\09MRR1.SGM 09MRR1 10362 Federal Register / Vol. 83, No. 47 / Friday, March 9, 2018 / Rules and Regulations final action has been identified, we might consider further rulemaking. Costs of Compliance We estimate that this AD affects 20 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. At an average labor rate of $85 per hour, inspecting 5 T/R hinges will require 8 hours, and required materials cost would be minimal, for a cost per helicopter of $680 and a cost of $13,600 to the U.S. fleet. Reporting the inspection findings would require about 30 minutes, for a cost per helicopter of $43 and a cost of $860 to the U.S. fleet. If required, dye-penetrant inspecting the spindle bolt or inner ring would require about 1 hour, and required materials cost would be minimal, for a cost per helicopter of $85. If required, replacing a spindle bolt would require about 1 hour, and required parts would cost $625, for a cost per helicopter of $710. If required, replacing the bearing race would require about 1 hour, and required parts would cost $585, for a cost per helicopter of $670. If required, replacing the inner ring would require about 1 hour, and required parts would cost $1,986, for a cost per helicopter of $2,071. amozie on DSK30RV082PROD with RULES Paperwork Reduction Act A federal agency may not conduct or sponsor, and a person is not required to respond to, nor shall a person be subject to penalty for failure to comply with a collection of information subject to the requirements of the Paperwork Reduction Act unless that collection of information displays a current valid OMB control number. The control number for the collection of information required by this AD is 2120–0056. The paperwork cost associated with this AD has been detailed in the Costs of Compliance section of this document and includes time for reviewing instructions, as well as completing and reviewing the collection of information. Therefore, all reporting required by this AD is mandatory. Comments concerning the accuracy of this burden and suggestions for reducing the burden should be directed to the FAA at 800 Independence Ave, SW, Washington, DC 20591. ATTN: Information Collection Clearance Officer, AES–200. FAA’s Justification and Determination of the Effective Date An unsafe condition exists that requires the immediate adoption of this AD without providing an opportunity for public comments prior to adoption. The FAA has found that the risk to the flying public justifies waiving notice VerDate Sep<11>2014 15:43 Mar 08, 2018 Jkt 244001 and comment prior to adoption of this rule because the inspections required by this AD must be accomplished within 25 hours TIS, a relatively short period of time for these helicopters as they are primarily used for offshore operations. Therefore, we find good cause that notice and opportunity for prior public comment are impracticable. In addition, for the reason stated above, we find that good cause exists for making this amendment effective in less than 30 days. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. 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, I certify that this AD: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; 2. Is not a ‘‘significant rule’’ under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979); 3. Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction; 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. We prepared an economic evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

Discussion

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued Emergency AD No. 2017-0232-E, dated November 
21, 2017, to correct an unsafe condition for Airbus Helicopters Model 
AS 332 C, AS 332 C1, AS 332 L, and AS 332 L1 helicopters. The EASA AD 
was prompted by the in-flight failure of a pin in a hinge attaching the 
T/R. EASA advises that damage to the hinge on a T/R blade was reported 
and that an investigation is ongoing to determine the root cause of the 
damage. EASA further advises that this condition could lead to failure 
of the hinge, unbalance of the T/R, and detachment of the T/R gearbox 
and hub with subsequent loss of control of the helicopter. To correct 
this unsafe condition, the EASA AD requires a one-time inspection of 
the flapping hinges, and depending on the findings, corrective actions. 
It also requires reporting the findings and sending any cracked 
components to Airbus Helicopters to support the investigation.

FAA's Determination

    These helicopters have been approved by the aviation authority of 
France and are approved for operation in the United States. Pursuant to 
our bilateral agreement with France, EASA, its technical 
representative, has notified us of the unsafe condition described in 
the EASA AD. We are issuing this AD because we evaluated all 
information provided by EASA and determined the unsafe condition exists 
and is likely to exist or develop on other helicopters of these same 
type designs.

Related Service Information Under 1 CFR Part 51

    We reviewed Airbus Helicopters Emergency Alert Service Bulletin 
(EASB) No. 64.00.43, Revision 0, dated November 21, 2017, for Model 
AS332-series helicopters. This service information describes procedures 
for visually and dye penetrant inspecting the hinges of all five T/Rs.
    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.

AD Requirements

    This AD requires, within 25 hours time-in-service (TIS):
     Performing a tactile inspection of each hinge for friction 
points;
     Measuring for play in the drag plane;
     Measuring the tightening torque of each spindle bolt.
    [cir] If the tightening torque is not within the minimum and 
maximum torque, dye-penetrant inspecting the spindle bolt for a crack 
and removing the spindle bolt and hexagonal castellated nut from 
service;
    [cir] If the tightening torque is within the minimum and maximum 
torque, inspecting the spindle bolt for corrosion and fretting.
     Inspecting the bearing race inner ring and bearing needles 
for spalling and replacing the bearing race if there is any spalling;
     Measuring the thickness of each stop washer and removing 
the stop washer from service if the thickness is less than 1.5 mm (.060 
inch); and
     Inspecting the inner ring for brinelling.
    [cir] If there is brinelling deeper than 0.1 mm (.004 inch), 
repairing the hinge.
    [cir] If there is brinelling 0.1 mm (.004 inch) or less, dye-
penetrant inspecting the inner ring for a crack.
    This AD also requires, within 10 days after the inspection, 
reporting the results of each inspection and measurement to Airbus 
Helicopters.

Differences Between This AD and the EASA AD

    The EASA AD requires compliance within 25 hours TIS or at the next 
50 hour inspection of the T/R, whichever is later; this AD requires 
compliance within 25 hours TIS. The EASA AD requires returning parts to 
Airbus Helicopters, and this AD does not.

Interim Action

    We considered this AD interim action. The inspection reports that 
are required by this AD will enable Airbus Helicopters to obtain better 
insight into the cause of the damaged flapping hinge link, and 
eventually develop final action to address the unsafe condition. Once

[[Page 10362]]

final action has been identified, we might consider further rulemaking.

Costs of Compliance

    We estimate that this AD affects 20 helicopters of U.S. Registry.
    We estimate that operators may incur the following costs in order 
to comply with this AD. At an average labor rate of $85 per hour, 
inspecting 5 T/R hinges will require 8 hours, and required materials 
cost would be minimal, for a cost per helicopter of $680 and a cost of 
$13,600 to the U.S. fleet. Reporting the inspection findings would 
require about 30 minutes, for a cost per helicopter of $43 and a cost 
of $860 to the U.S. fleet. If required, dye-penetrant inspecting the 
spindle bolt or inner ring would require about 1 hour, and required 
materials cost would be minimal, for a cost per helicopter of $85. If 
required, replacing a spindle bolt would require about 1 hour, and 
required parts would cost $625, for a cost per helicopter of $710.
    If required, replacing the bearing race would require about 1 hour, 
and required parts would cost $585, for a cost per helicopter of $670.
    If required, replacing the inner ring would require about 1 hour, 
and required parts would cost $1,986, for a cost per helicopter of 
$2,071.

Paperwork Reduction Act

    A federal agency may not conduct or sponsor, and a person is not 
required to respond to, nor shall a person be subject to penalty for 
failure to comply with a collection of information subject to the 
requirements of the Paperwork Reduction Act unless that collection of 
information displays a current valid OMB control number. The control 
number for the collection of information required by this AD is 2120-
0056. The paperwork cost associated with this AD has been detailed in 
the Costs of Compliance section of this document and includes time for 
reviewing instructions, as well as completing and reviewing the 
collection of information. Therefore, all reporting required by this AD 
is mandatory. Comments concerning the accuracy of this burden and 
suggestions for reducing the burden should be directed to the FAA at 
800 Independence Ave, SW, Washington, DC 20591. ATTN: Information 
Collection Clearance Officer, AES-200.

FAA's Justification and Determination of the Effective Date

    An unsafe condition exists that requires the immediate adoption of 
this AD without providing an opportunity for public comments prior to 
adoption. The FAA has found that the risk to the flying public 
justifies waiving notice and comment prior to adoption of this rule 
because the inspections required by this AD must be accomplished within 
25 hours TIS, a relatively short period of time for these helicopters 
as they are primarily used for offshore operations. Therefore, we find 
good cause that notice and opportunity for prior public comment are 
impracticable.
    In addition, for the reason stated above, we find that good cause 
exists for making this amendment effective in less than 30 days.

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, I certify that this AD:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979);
    3. Will not affect intrastate aviation in Alaska to the extent that 
it justifies making a regulatory distinction; 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.
    We prepared an economic evaluation of the estimated costs to comply 
with this AD and placed it in the AD docket.
