The purpose of these notices is to give interested persons an opportunity to participate in the rule making prior to the adoption of the final rules. DEPARTMENT OF TRANSPORTATION Federal Aviation Administration 14 CFR Part 39 [Docket No. FAA–2018–0994; Product Identifier 2017–SW–002–AD] RIN 2120–AA64 Airworthiness Directives; Airbus Helicopters Federal Aviation Administration (FAA), DOT. ACTION: Notice of proposed rulemaking (NPRM). AGENCY: The FAA proposes to supersede Airworthiness Directive (AD) 2017–14–05 for Airbus Helicopters Model SA330J helicopters. AD 2017– 14–05 requires replacing certain righthand (RH) hydraulic pumps and is prompted by reports of broken screws that attach the cover of the hydraulic pump. This proposed AD would continue to require the same actions as AD 2017–14–05 but would also require replacing the left-hand (LH) hydraulic pump. The actions of this proposed AD are intended to address an unsafe condition on these products. DATES: The FAA must receive comments on this proposed AD by December 20, 2019. ADDRESSES: You may send comments by any of the following methods: • Federal eRulemaking Docket: Go to http://www.regulations.gov.

SUPPLEMENTARY INFORMATION: Comments Invited The FAA invites you to participate in this rulemaking by submitting written comments, data, or views. The FAA also invites comments relating to the economic, environmental, energy, or federalism impacts that might result from adopting the proposals in this document. The most helpful comments reference a specific portion of the proposal, explain the reason for any recommended change, and include supporting data. To ensure the docket does not contain duplicate comments, commenters should send only one copy of written comments, or if comments are filed electronically, commenters should submit only one time. The FAA will file in the docket all comments received, as well as a report summarizing each substantive public contact with FAA personnel concerning this proposed rulemaking. Before acting on this proposal, the FAA will consider PO 00000 Frm 00001 Fmt 4702 Sfmt 4702 all comments received on or before the closing date for comments. The FAA will consider comments filed after the comment period has closed if it is possible to do so without incurring expense or delay. The FAA may change this proposal in light of the comments received. Discussion The FAA issued a final rule; request for comment to AD 2017–14–05, Amendment 39–18949 (82 FR 31899, July 11, 2017) (‘‘AD 2017–14–05’’) for Airbus Helicopters Model SA330J helicopters with a LH and RH hydraulic pump part number (P/N) FR65WEO2005–175A with a serial number 4108, 4141, 4177, 4227, 4241, 4284, 4377, 4422, 4570, 4573, 4574, 4641, 4649, 4668, 4766, 4802, 4821, 4831, 4837, 4888, 4896, 4946, 4985, 5023, 5071, 5304, 5366, 5376, 5409, 5442, 5486, 5599, 5630, 94075/01, or 94048/01 installed. AD 2017–14–05 requires replacing the RH hydraulic pump within 15 hours time-in-service. AD 2017–14–05 was prompted by EASA Emergency AD No. 2016–264–E, dated December 22, 2016 (EASA AD 2016–264–E), issued by EASA, to correct an unsafe condition for Airbus Helicopters Model SA330J helicopters. EASA advises of reports of broken screws that attach the cover of the hydraulic pump. A subsequent investigation revealed that hydrogen was introduced into a batch of screws delivered between July 1, 2015, and November 1, 2016, causing the screws to become brittle and lack sufficient strength. These screws were installed in a batch of hydraulic pumps, P/N FR65WEO2005–175A, identified by certain serial numbers, EASA advises. As a result, the EASA AD requires replacing the hydraulic pumps. The actions of AD 2017–14–05 were intended to prevent failure of a cover bolt and loss of fluid from the hydraulic pump, resulting in loss of the hydraulic system and subsequent loss of helicopter control. This NPRM would retain the requirements of AD 2017–14–05 but would also require replacing the LH hydraulic pump within 110 hours TIS. Because this proposed action would have a longer compliance time, the FAA is providing the public an opportunity to comment. E:\FR\FM\21OCP1.SGM 21OCP1 Federal Register / Vol. 84, No. 203 / Monday, October 21, 2019 / Proposed Rules Comments After AD 2017–14–05 was published, the FAA received two comments from Airbus Helicopters. Airbus Helicopters requested that the FAA clarify the requirement in AD 2017–14–05 to only replace the RH hydraulic pump, when EASA AD 2016– 0264–E requires replacing both the RH and LH hydraulic pumps. The FAA agrees that the LH hydraulic pump also needs to be replaced. AD 2017–14–05 was issued as a final rule; request for comments and was effective in less than 30 days because it required replacing the RH hydraulic pump within a short time period. When the FAA issued AD 2017–14–05, the FAA explained that the compliance time for replacing the LH hydraulic pump allowed enough time to provide notice and opportunity for prior public comment. This proposed AD would require replacing both the RH and LH hydraulic pumps. Airbus Helicopters also requested that the FAA clarify whether the pumps listed in the Applicability of AD 2017– 14–05 by P/N and serial number are serviceable because EASA AD 2016– 264–E allows those pumps to be installed if repaired in accordance with Mechanics Alert Service Bulletin No. NM/INGE/16–140, Revision 0, dated December 22, 2016 (Nexter ASB). Airbus Helicopters is correct that the pumps listed by P/N and serial number in the Applicability section of AD 2017– 14–05 are not serviceable. Paragraph (e)(2) of AD 2017–14–05 prohibits installing those pumps on any helicopter. One of the instructions in the Nexter ASB is to re-identify the pump by adding a ‘‘V’’ after the serial number. If a pump has been repaired in accordance with the Nexter ASB, this AD will not apply because the pump will have a serial number that is not listed in the Applicability section of this AD. khammond on DSKJM1Z7X2PROD with PROPOSALS 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 proposing this AD after evaluating all known relevant information and determined that an unsafe condition is likely to exist or develop on other products of the same type design. Related Service Information The FAA reviewed Airbus Helicopters Emergency Alert Service Bulletin No. VerDate Sep<11>2014 16:24 Oct 18, 2019 Jkt 250001 SA330–29.12, Revision 0, dated December 22, 2016 (Airbus EASB), for Model SA330J helicopters and military model SA330L, SA330Jm, SA330S1, and SA330Sm helicopters. The Airbus EASB specifies removing Nexter Mechanics hydraulic pumps P/N FR65WEO2005–175A with certain serial numbers. If both the RH and LH hydraulic pumps have an affected P/N and serial number, the Airbus EASB specifies replacing the RH hydraulic pump before further flight and the LH hydraulic pump within 110 flying hours or 6 months. If only one hydraulic pump has an affected P/N and serial number, the Airbus EASB specifies replacing it within 110 flying hours or 6 months. The Airbus EASB also specifies that, for 6 months after receipt of the Airbus EASB, before installing an affected hydraulic pump it must be ‘‘returned to conformity’’ by complying with Nexter ASB. After 6 months or 110 flying hours, whichever occurs first, the Airbus ASB states the affected hydraulic pumps are unfit for flight. Proposed AD Requirements This proposed AD would require replacing the RH hydraulic pump within 15 hours TIS and replacing the LH hydraulic pump within 110 hours TIS. This proposed AD would also prohibit installation of an affected hydraulic pump on any helicopter. Costs of Compliance The FAA estimates that this AD would affect 24 helicopters and that labor costs average $85 per work-hour. Based on these estimates, the FAA expects that replacing two hydraulic pumps would require 4 work-hours and parts cost $5,000 for a total cost of $5,340 per helicopter and $128,160 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. 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 PO 00000 Frm 00002 Fmt 4702 Sfmt 4702 56153 unsafe condition that is likely to exist or develop on products identified in this rulemaking action. Regulatory Findings The FAA 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, I certify this proposed regulation: 1. Is not a ‘‘significant regulatory action’’ under Executive Order 12866; 2. Will not affect intrastate aviation in Alaska to the extent that it justifies making a regulatory distinction; 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. The FAA prepared an economic evaluation of the estimated costs to comply with this proposed AD and placed it in the AD docket.

Airworthiness Directives; Airbus Helicopters

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 
2017-14-05 for Airbus Helicopters Model SA330J helicopters. AD 2017-14-
05 requires replacing certain right-hand (RH) hydraulic pumps and is 
prompted by reports of broken screws that attach the cover of the 
hydraulic pump. This proposed AD would continue to require the same 
actions as AD 2017-14-05 but would also require replacing the left-hand 
(LH) hydraulic pump. The actions of this proposed AD are intended to 
address an unsafe condition on these products.

SUPPLEMENTARY INFORMATION: 

Comments Invited

    The FAA invites you to participate in this rulemaking by submitting 
written comments, data, or views. The FAA also invites comments 
relating to the economic, environmental, energy, or federalism impacts 
that might result from adopting the proposals in this document. The 
most helpful comments reference a specific portion of the proposal, 
explain the reason for any recommended change, and include supporting 
data. To ensure the docket does not contain duplicate comments, 
commenters should send only one copy of written comments, or if 
comments are filed electronically, commenters should submit only one 
time.
    The FAA will file in the docket all comments received, as well as a 
report summarizing each substantive public contact with FAA personnel 
concerning this proposed rulemaking. Before acting on this proposal, 
the FAA will consider all comments received on or before the closing 
date for comments. The FAA will consider comments filed after the 
comment period has closed if it is possible to do so without incurring 
expense or delay. The FAA may change this proposal in light of the 
comments received.

Discussion

    The FAA issued a final rule; request for comment to AD 2017-14-05, 
Amendment 39-18949 (82 FR 31899, July 11, 2017) (``AD 2017-14-05'') for 
Airbus Helicopters Model SA330J helicopters with a LH and RH hydraulic 
pump part number (P/N) FR65WEO2005-175A with a serial number 4108, 
4141, 4177, 4227, 4241, 4284, 4377, 4422, 4570, 4573, 4574, 4641, 4649, 
4668, 4766, 4802, 4821, 4831, 4837, 4888, 4896, 4946, 4985, 5023, 5071, 
5304, 5366, 5376, 5409, 5442, 5486, 5599, 5630, 94075/01, or 94048/01 
installed. AD 2017-14-05 requires replacing the RH hydraulic pump 
within 15 hours time-in-service.
    AD 2017-14-05 was prompted by EASA Emergency AD No. 2016-264-E, 
dated December 22, 2016 (EASA AD 2016-264-E), issued by EASA, to 
correct an unsafe condition for Airbus Helicopters Model SA330J 
helicopters. EASA advises of reports of broken screws that attach the 
cover of the hydraulic pump. A subsequent investigation revealed that 
hydrogen was introduced into a batch of screws delivered between July 
1, 2015, and November 1, 2016, causing the screws to become brittle and 
lack sufficient strength. These screws were installed in a batch of 
hydraulic pumps, P/N FR65WEO2005-175A, identified by certain serial 
numbers, EASA advises. As a result, the EASA AD requires replacing the 
hydraulic pumps.
    The actions of AD 2017-14-05 were intended to prevent failure of a 
cover bolt and loss of fluid from the hydraulic pump, resulting in loss 
of the hydraulic system and subsequent loss of helicopter control.
    This NPRM would retain the requirements of AD 2017-14-05 but would 
also require replacing the LH hydraulic pump within 110 hours TIS. 
Because this proposed action would have a longer compliance time, the 
FAA is providing the public an opportunity to comment.

[[Page 56153]]

Comments

    After AD 2017-14-05 was published, the FAA received two comments 
from Airbus Helicopters.
    Airbus Helicopters requested that the FAA clarify the requirement 
in AD 2017-14-05 to only replace the RH hydraulic pump, when EASA AD 
2016-0264-E requires replacing both the RH and LH hydraulic pumps.
    The FAA agrees that the LH hydraulic pump also needs to be 
replaced. AD 2017-14-05 was issued as a final rule; request for 
comments and was effective in less than 30 days because it required 
replacing the RH hydraulic pump within a short time period. When the 
FAA issued AD 2017-14-05, the FAA explained that the compliance time 
for replacing the LH hydraulic pump allowed enough time to provide 
notice and opportunity for prior public comment. This proposed AD would 
require replacing both the RH and LH hydraulic pumps.
    Airbus Helicopters also requested that the FAA clarify whether the 
pumps listed in the Applicability of AD 2017-14-05 by P/N and serial 
number are serviceable because EASA AD 2016-264-E allows those pumps to 
be installed if repaired in accordance with Mechanics Alert Service 
Bulletin No. NM/INGE/16-140, Revision 0, dated December 22, 2016 
(Nexter ASB).
    Airbus Helicopters is correct that the pumps listed by P/N and 
serial number in the Applicability section of AD 2017-14-05 are not 
serviceable. Paragraph (e)(2) of AD 2017-14-05 prohibits installing 
those pumps on any helicopter. One of the instructions in the Nexter 
ASB is to re-identify the pump by adding a ``V'' after the serial 
number. If a pump has been repaired in accordance with the Nexter ASB, 
this AD will not apply because the pump will have a serial number that 
is not listed in the Applicability section of this AD.

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 proposing this AD 
after evaluating all known relevant information and determined that an 
unsafe condition is likely to exist or develop on other products of the 
same type design.

Related Service Information

    The FAA reviewed Airbus Helicopters Emergency Alert Service 
Bulletin No. SA330-29.12, Revision 0, dated December 22, 2016 (Airbus 
EASB), for Model SA330J helicopters and military model SA330L, SA330Jm, 
SA330S1, and SA330Sm helicopters. The Airbus EASB specifies removing 
Nexter Mechanics hydraulic pumps P/N FR65WEO2005-175A with certain 
serial numbers. If both the RH and LH hydraulic pumps have an affected 
P/N and serial number, the Airbus EASB specifies replacing the RH 
hydraulic pump before further flight and the LH hydraulic pump within 
110 flying hours or 6 months. If only one hydraulic pump has an 
affected P/N and serial number, the Airbus EASB specifies replacing it 
within 110 flying hours or 6 months. The Airbus EASB also specifies 
that, for 6 months after receipt of the Airbus EASB, before installing 
an affected hydraulic pump it must be ``returned to conformity'' by 
complying with Nexter ASB. After 6 months or 110 flying hours, 
whichever occurs first, the Airbus ASB states the affected hydraulic 
pumps are unfit for flight.

Proposed AD Requirements

    This proposed AD would require replacing the RH hydraulic pump 
within 15 hours TIS and replacing the LH hydraulic pump within 110 
hours TIS. This proposed AD would also prohibit installation of an 
affected hydraulic pump on any helicopter.

Costs of Compliance

    The FAA estimates that this AD would affect 24 helicopters and that 
labor costs average $85 per work-hour. Based on these estimates, the 
FAA expects that replacing two hydraulic pumps would require 4 work-
hours and parts cost $5,000 for a total cost of $5,340 per helicopter 
and $128,160 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.
    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 products identified in this rulemaking action.

Regulatory Findings

    The FAA 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, I certify this proposed regulation:
    1. Is not a ``significant regulatory action'' under Executive Order 
12866;
    2. Will not affect intrastate aviation in Alaska to the extent that 
it justifies making a regulatory distinction; 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.
    The FAA prepared an economic evaluation of the estimated costs to 
comply with this proposed AD and placed it in the AD docket.
