SUPPLEMENTARY INFORMATION: Discussion AD 2018–01–12, Amendment 39– 19153 (83 FR 2039, January 16, 2018) applied to Airbus Helicopters Model AS350B3 helicopters with a dual hydraulic system installed. AD 2018– 01–12 required revising the rotorcraft flight manual (RFM) to perform the yaw load compensator check (ACCU TST switch) after rotor shut-down instead of during preflight procedures and to state that the yaw servo hydraulic switch (collective switch) must be in the ‘‘ON’’ (forward) position before taking off. AD 2018–01–12 also required modifying the yaw servo hydraulic switch and replacing the bistable ACCU TST button with a monostable button. We issued AD 2018–01–12 to prevent takeoff without hydraulic pressure in the tail rotor (T/R) hydraulic system, loss of T/R flight control, and subsequent loss of control of the helicopter. As published, AD 2018–01–12 contained an incorrect P/N in the preamble and regulatory text. Specifically, the AD identified the Geneva Aviation P122 and P132 electrical console monostable toggle switch P/N as ‘‘MS24658–16F.’’ The correct P/N is ‘‘MS24658–26F.’’ Accordingly, we have determined that it is appropriate to take action to revise AD 2018–01–12 to correct the Geneva Aviation P122 and P132 electrical console monostable toggle switch P/N. PO 00000 Frm 00001 Fmt 4700 Sfmt 4700 This correction will ensure that it will be possible for operators to comply with the AD by referencing the correct P/N for replacing the toggle switch. No other part of the preamble or regulatory information has been changed. The final rule is reprinted in its entirety for the convenience of affected operators. Impact of the Correction Since this action corrects an obvious error in referencing the P/N for a replacement part, it has no adverse economic impact and imposes no additional burden on any person. Therefore, we find that notice and opportunity for prior public comment are unnecessary and that good cause exists for making this amendment effective in less than 30 days. Related Service Information Under 1 CFR Part 51 We reviewed Airbus Helicopters Service Bulletin (SB) No. AS350– 67.00.64, Revision 0, dated February 25, 2015. This service information specifies procedures to install a timer relay and an additional indicator light on the caution and warning panel. This modification provides an ‘‘OFF’’ status indication of the yaw servo hydraulic switch by flashing a newly installed ‘‘HYD2’’ indicator light on the caution and warning panel. Airbus Helicopters identifies performance of this SB as modification 074622. We also reviewed Airbus Helicopters SB No. AS350–67.00.65, Revision 0, dated August 25, 2016. This service information specifies procedures to replace the bistable push button ACCU TST switch with a monostable push button switch. Airbus Helicopters identifies performance of this SB as modification 074719. 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. Other Related Service Information We reviewed Airbus Helicopters SB No. AS350–67.00.66, Revision 1, dated October 22, 2015. This service information specifies inserting specific pages of the SB into the rotorcraft flight manual. These pages revise the preflight and post-flight hydraulic checks by moving the T/R yaw load compensator check from preflight to post-flight. E:\FR\FM\02MRR1.SGM 02MRR1 8928 Federal Register / Vol. 83, No. 42 / Friday, March 2, 2018 / Rules and Regulations These pages also revise terminology within the flight manuals for the different engine configurations. 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 the same type design. daltland on DSKBBV9HB2PROD with RULES Costs of Compliance We estimate that this AD affects 86 helicopters of U.S. Registry. We estimate that operators may incur the following costs in order to comply with this AD. Labor costs are estimated at $85 per work-hour. Revising an RFM takes about 0.5 work-hour for a cost of $43 per helicopter and $3,698 for the U.S. fleet. Installing a timer relay for the yaw servo hydraulic switch and an indicator light takes about 9 work-hours and parts cost about $2,224. Replacing the ACCU TST button takes about 1 work-hour and parts cost about $2,244. Based on these figures, we estimate a total cost of $5,361 per helicopter and $461,046 for the U.S. fleet. 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 VerDate Sep<11>2014 16:25 Mar 01, 2018 Jkt 244001 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.

SUPPLEMENTARY INFORMATION: 

Discussion

    AD 2018-01-12, Amendment 39-19153 (83 FR 2039, January 16, 2018) 
applied to Airbus Helicopters Model AS350B3 helicopters with a dual 
hydraulic system installed. AD 2018-01-12 required revising the 
rotorcraft flight manual (RFM) to perform the yaw load compensator 
check (ACCU TST switch) after rotor shut-down instead of during 
preflight procedures and to state that the yaw servo hydraulic switch 
(collective switch) must be in the ``ON'' (forward) position before 
taking off. AD 2018-01-12 also required modifying the yaw servo 
hydraulic switch and replacing the bistable ACCU TST button with a 
monostable button.
    We issued AD 2018-01-12 to prevent takeoff without hydraulic 
pressure in the tail rotor (T/R) hydraulic system, loss of T/R flight 
control, and subsequent loss of control of the helicopter.
    As published, AD 2018-01-12 contained an incorrect P/N in the 
preamble and regulatory text. Specifically, the AD identified the 
Geneva Aviation P122 and P132 electrical console monostable toggle 
switch P/N as ``MS24658-16F.'' The correct P/N is ``MS24658-26F.''
    Accordingly, we have determined that it is appropriate to take 
action to revise AD 2018-01-12 to correct the Geneva Aviation P122 and 
P132 electrical console monostable toggle switch P/N. This correction 
will ensure that it will be possible for operators to comply with the 
AD by referencing the correct P/N for replacing the toggle switch.
    No other part of the preamble or regulatory information has been 
changed. The final rule is reprinted in its entirety for the 
convenience of affected operators.

Impact of the Correction

    Since this action corrects an obvious error in referencing the P/N 
for a replacement part, it has no adverse economic impact and imposes 
no additional burden on any person. Therefore, we find that notice and 
opportunity for prior public comment are unnecessary and that good 
cause exists for making this amendment effective in less than 30 days.

Related Service Information Under 1 CFR Part 51

    We reviewed Airbus Helicopters Service Bulletin (SB) No. AS350-
67.00.64, Revision 0, dated February 25, 2015. This service information 
specifies procedures to install a timer relay and an additional 
indicator light on the caution and warning panel. This modification 
provides an ``OFF'' status indication of the yaw servo hydraulic switch 
by flashing a newly installed ``HYD2'' indicator light on the caution 
and warning panel. Airbus Helicopters identifies performance of this SB 
as modification 074622.
    We also reviewed Airbus Helicopters SB No. AS350-67.00.65, Revision 
0, dated August 25, 2016. This service information specifies procedures 
to replace the bistable push button ACCU TST switch with a monostable 
push button switch. Airbus Helicopters identifies performance of this 
SB as modification 074719.
    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.

Other Related Service Information

    We reviewed Airbus Helicopters SB No. AS350-67.00.66, Revision 1, 
dated October 22, 2015. This service information specifies inserting 
specific pages of the SB into the rotorcraft flight manual. These pages 
revise the preflight and post-flight hydraulic checks by moving the T/R 
yaw load compensator check from preflight to post-flight.

[[Page 8928]]

These pages also revise terminology within the flight manuals for the 
different engine configurations.

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 the same type 
design.

Costs of Compliance

    We estimate that this AD affects 86 helicopters of U.S. Registry. 
We estimate that operators may incur the following costs in order to 
comply with this AD. Labor costs are estimated at $85 per work-hour.
    Revising an RFM takes about 0.5 work-hour for a cost of $43 per 
helicopter and $3,698 for the U.S. fleet. Installing a timer relay for 
the yaw servo hydraulic switch and an indicator light takes about 9 
work-hours and parts cost about $2,224. Replacing the ACCU TST button 
takes about 1 work-hour and parts cost about $2,244.
    Based on these figures, we estimate a total cost of $5,361 per 
helicopter and $461,046 for the U.S. fleet.

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.

for Model AS350B3 helicopters is referred to as Airbus modification 
OP 3082 or OP 3346.

(b) Unsafe Condition

    This AD defines the unsafe condition as lack of hydraulic 
pressure in a tail rotor (T/R) hydraulic system. This condition 
could result in loss of T/R flight control and subsequent loss of 
control of the helicopter.

(c) Affected ADs

    This AD replaces AD 2018-01-12, Amendment 39-19153 (83 FR 2039, 
January 16, 2018).

(d) Effective Date

    This AD becomes effective March 2, 2018.

(e) Compliance

    You are responsible for performing each action required by this 
AD within the specified compliance time unless it has already been 
accomplished prior to that time.

(f) Required Actions

    (1) Before further flight, insert a copy of this AD into the 
rotorcraft flight manual, Section 4 Normal Operating Procedures, or 
make pen and ink changes to the preflight and post-flight procedures 
as follows:
    (i) Stop performing the yaw load compensator check (ACCU TST 
switch) during preflight procedures, and instead perform the yaw 
load compensator check during post-flight procedures after rotor 
shut-down.
    (ii) The yaw servo hydraulic switch (collective switch) must be 
in the ``ON'' (forward) position before takeoff.

    Note 2 to paragraph (f)(1)(ii) of this AD:  The yaw servo 
hydraulic switch is also called the hydraulic pressure switch or 
hydraulic cut off switch in various Airbus Helicopters rotorcraft 
flight manuals.

    (2) Within 350 hours time-in-service:
    (i) Install a timer relay for the yaw servo hydraulic switch 
(collective switch) by following the Accomplishment Instructions,
