SUPPLEMENTARY INFORMATION: Discussion On December 9, 2019, at 84 FR 67246, the Federal Register published the FAA’s notice of proposed rulemaking (NPRM), which proposed to amend 14 CFR part 39 by adding an AD that would apply to Airbus Helicopters Model AS332C, AS332C1, AS332L, and AS332L1 helicopters, with an MGB suspension bar right-hand side (RH) rear fitting part number (P/N) 330A22–2702– 07 and bolt P/N 330A22–0135–20, MGB suspension bar left-hand side (LH) rear fitting P/N 330A22–2702–06 and bolt P/ N 330A22–0135–20, or MGB suspension bar front bolt P/N 330A22–0134–20 installed. The NPRM proposed to require within 50 hours TIS, reviewing the helicopter records to determine the total hours TIS of the MGB suspension bar RH and LH rear fittings. The NPRM also proposed to require removing from service the RH rear fitting and its bolts and the LH rear fitting and its bolts based on the accumulated total hours TIS of the fittings and other conditions. Thereafter, the NPRM proposed to require removing from service the RH rear fitting and its bolts at intervals not to exceed 1,470 hours TIS, removing from service the LH rear fitting at intervals not to exceed 13,600 hours TIS, and removing from service the LH rear bolts during each Major Inspection ‘‘G.’’ Finally, the NPRM proposed to require removing from service the front bolts during each Major Inspection ‘‘G.’’ The proposed requirements were intended to prevent structural failure of the MGB suspension bar fittings and bolts, possibly resulting in detachment of the MGB suspension bars. The NPRM was prompted by EASA AD No. 2018–0260, dated December 3, 2018, issued by EASA, which is the Technical Agent for the Member States of the European Union, to correct an unsafe condition for Airbus Helicopters (formerly Eurocopter, Eurocopter France, Aerospatiale) Model AS 332 C, AS 332 C1, AS 332 L, and AS 332 L1 helicopters. From review of reported Model EC 225 LP data, EASA advises that the installation of the MGB upper deck fittings of the three MGB suspension bars could lead to tightening torque loss on the fittings’ attachment screws (bolts). Due to design similarities, Model AS 332 C, AS 332 C1, AS 332 L, and AS 332 L1 helicopters could also be affected by the same installation condition. E:\FR\FM\06APR1.SGM 06APR1 Federal Register / Vol. 85, No. 66 / Monday, April 6, 2020 / Rules and Regulations Investigations determined that a life limit reduction of the MGB suspension bar fittings and screws was necessary for these model helicopters. EASA states that this condition, if not corrected, could lead to structural failure of the MGB suspension bar fittings and screws, possibly resulting in detachment of the MGB suspension bars. Accordingly, the EASA AD requires determining the accumulated service life of the affected parts and introduced new life limits. Comments The FAA gave the public the opportunity to participate in developing this AD, but the FAA did not receive any comments on the NPRM. FAA’s Determination These helicopters have been approved by EASA and are approved for operation in the United States. Pursuant to the FAA’s bilateral agreement with the European Union, EASA has notified the FAA of the unsafe condition described in its AD. The FAA is issuing this AD after evaluating all information provided by EASA and determining the unsafe condition exists and is likely to exist or develop on other helicopters of these same type designs and that air safety and the public interest require adopting the AD requirements as proposed. Interim Action The FAA considers this AD to be an interim action. The design approval holder is currently developing a modification that will address the unsafe condition identified in this AD. Once this modification is developed, approved, and available, the FAA might consider additional rulemaking. jbell on DSKJLSW7X2PROD with RULES Differences Between This AD and the EASA AD The EASA AD allows an option for the first MGB RH rear fitting replacement to inspect torque and specifies different replacement compliance times based on the torque inspection results, whereas this AD does not. Related Service Information The FAA reviewed Airbus Helicopters Alert Service Bulletin No. AS332– 01.00.90, Revision 0, dated November 21, 2018. This service information specifies determining the accumulated hours TIS of certain part-numbered rear MGB suspension bar fittings and screws. This service information further specifies criteria to determine the initial replacement compliance time of those parts and a new life limit for those parts VerDate Sep<11>2014 16:25 Apr 03, 2020 Jkt 250001 thereafter. This service information also establishes a life limit for the front MGB attachment screws. Costs of Compliance The FAA estimates that this AD affects 14 helicopters of U.S. Registry. The FAA estimates that operators may incur the following costs in order to comply with this AD. Labor costs are estimated at $85 per work-hour. Determining the total hours TIS of the rear MGB fittings takes about 0.5 workhour for an estimated cost of $43 per helicopter and $602 for the U.S. fleet. Replacing a rear MGB fitting and its set of four bolts takes about 8 workhours and parts cost about $12,937, for an estimated cost of $13,617 per replacement cycle. Replacing a set of four MGB attachment bolts takes about 4 workhours and parts cost about $224, for an estimated cost of $564 per replacement cycle. Replacing a LH rear MGB fitting takes about 8 work-hours and parts cost about $12,713, for an estimated cost of $13,393 per replacement cycle. 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. The FAA is 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 helicopters identified in this rulemaking action. Regulatory Findings 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, PO 00000 Frm 00005 Fmt 4700 Sfmt 4700 19081 2. Will not affect intrastate aviation in Alaska, and 3. 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:

Discussion

    On December 9, 2019, at 84 FR 67246, the Federal Register published 
the FAA's notice of proposed rulemaking (NPRM), which proposed to amend 
14 CFR part 39 by adding an AD that would apply to Airbus Helicopters 
Model AS332C, AS332C1, AS332L, and AS332L1 helicopters, with an MGB 
suspension bar right-hand side (RH) rear fitting part number (P/N) 
330A22-2702-07 and bolt P/N 330A22-0135-20, MGB suspension bar left-
hand side (LH) rear fitting P/N 330A22-2702-06 and bolt P/N 330A22-
0135-20, or MGB suspension bar front bolt P/N 330A22-0134-20 installed. 
The NPRM proposed to require within 50 hours TIS, reviewing the 
helicopter records to determine the total hours TIS of the MGB 
suspension bar RH and LH rear fittings. The NPRM also proposed to 
require removing from service the RH rear fitting and its bolts and the 
LH rear fitting and its bolts based on the accumulated total hours TIS 
of the fittings and other conditions. Thereafter, the NPRM proposed to 
require removing from service the RH rear fitting and its bolts at 
intervals not to exceed 1,470 hours TIS, removing from service the LH 
rear fitting at intervals not to exceed 13,600 hours TIS, and removing 
from service the LH rear bolts during each Major Inspection ``G.'' 
Finally, the NPRM proposed to require removing from service the front 
bolts during each Major Inspection ``G.''
    The proposed requirements were intended to prevent structural 
failure of the MGB suspension bar fittings and bolts, possibly 
resulting in detachment of the MGB suspension bars.
    The NPRM was prompted by EASA AD No. 2018-0260, dated December 3, 
2018, issued by EASA, which is the Technical Agent for the Member 
States of the European Union, to correct an unsafe condition for Airbus 
Helicopters (formerly Eurocopter, Eurocopter France, Aerospatiale) 
Model AS 332 C, AS 332 C1, AS 332 L, and AS 332 L1 helicopters. From 
review of reported Model EC 225 LP data, EASA advises that the 
installation of the MGB upper deck fittings of the three MGB suspension 
bars could lead to tightening torque loss on the fittings' attachment 
screws (bolts). Due to design similarities, Model AS 332 C, AS 332 C1, 
AS 332 L, and AS 332 L1 helicopters could also be affected by the same 
installation condition.

[[Page 19081]]

Investigations determined that a life limit reduction of the MGB 
suspension bar fittings and screws was necessary for these model 
helicopters.
    EASA states that this condition, if not corrected, could lead to 
structural failure of the MGB suspension bar fittings and screws, 
possibly resulting in detachment of the MGB suspension bars. 
Accordingly, the EASA AD requires determining the accumulated service 
life of the affected parts and introduced new life limits.

Comments

    The FAA gave the public the opportunity to participate in 
developing this AD, but the FAA did not receive any comments on the 
NPRM.

FAA's Determination

    These helicopters have been approved by EASA and are approved for 
operation in the United States. Pursuant to the FAA's bilateral 
agreement with the European Union, EASA has notified the FAA of the 
unsafe condition described in its AD. The FAA is issuing this AD after 
evaluating all information provided by EASA and determining the unsafe 
condition exists and is likely to exist or develop on other helicopters 
of these same type designs and that air safety and the public interest 
require adopting the AD requirements as proposed.

Interim Action

    The FAA considers this AD to be an interim action. The design 
approval holder is currently developing a modification that will 
address the unsafe condition identified in this AD. Once this 
modification is developed, approved, and available, the FAA might 
consider additional rulemaking.

Differences Between This AD and the EASA AD

    The EASA AD allows an option for the first MGB RH rear fitting 
replacement to inspect torque and specifies different replacement 
compliance times based on the torque inspection results, whereas this 
AD does not.

Related Service Information

    The FAA reviewed Airbus Helicopters Alert Service Bulletin No. 
AS332-01.00.90, Revision 0, dated November 21, 2018. This service 
information specifies determining the accumulated hours TIS of certain 
part-numbered rear MGB suspension bar fittings and screws. This service 
information further specifies criteria to determine the initial 
replacement compliance time of those parts and a new life limit for 
those parts thereafter. This service information also establishes a 
life limit for the front MGB attachment screws.

Costs of Compliance

    The FAA estimates that this AD affects 14 helicopters of U.S. 
Registry. The FAA estimates that operators may incur the following 
costs in order to comply with this AD. Labor costs are estimated at $85 
per work-hour.
    Determining the total hours TIS of the rear MGB fittings takes 
about 0.5 work-hour for an estimated cost of $43 per helicopter and 
$602 for the U.S. fleet.
    Replacing a rear MGB fitting and its set of four bolts takes about 
8 work-hours and parts cost about $12,937, for an estimated cost of 
$13,617 per replacement cycle.
    Replacing a set of four MGB attachment bolts takes about 4 work-
hours and parts cost about $224, for an estimated cost of $564 per 
replacement cycle.
    Replacing a LH rear MGB fitting takes about 8 work-hours and parts 
cost about $12,713, for an estimated cost of $13,393 per replacement 
cycle.

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.
    The FAA is 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 helicopters identified in this rulemaking action.

Regulatory Findings

    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. Will not affect intrastate aviation in Alaska, and
    3. 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.
