Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Background EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2020–0013, dated January 29, 2020 (EASA AD 2020–0013), to correct an unsafe condition for Airbus Helicopters Model AS 332 C, C1, L, L1, and L2, AS 365 N2 and N3, EC 155 B and B1, EC 175 B, EC 225 LP, SA 330 J, and SA 365 C1, C2, C3, N, and N1 helicopters; Airbus Helicopters Deutschland GmbH Model EC135 P1, P2, P2+, P3, T1, T2, T2+, and T3, EC635 P2+, P3, T1, T2+, and T3, and MBB–BK117 A–1, A–3, A–4, B–1, B–2, C–1, C–2, and D–2 helicopters; Leonardo S.p.A. Model AB139, AB 204B, AB 205 A–1, AB 212, AB 412, AB 412EP, AS–61N, AS–61N1, AW139, AW169, and AW189 helicopters; and WSK PZL—S´WIDNIK S.A. Model PZL W–3A and PZL W–3AS helicopters. EASA advises of occurrences that have been reported of a quality issue on certain fire extinguishers, manufactured by Umlaut Engineering GmbH (formerly P3 Engineering GmbH), where the spindle geometries of the extinguishers were found to be out of tolerance. The manufacturing defect identified in certain serial-numbered fire extinguisher part numbers (P/Ns) P3APP003010A and P3APP003010C with a manufacturing date of March 2019 through July 2019 inclusive, where prolonged exposure (12 hours or more) to high temperature conditions of more than 68 °C (154.4 °F) could cause a nondetectable seizure of the spindle that could cause the fire extinguisher to be inoperative. This condition, if not E:\FR\FM\08OCP1.SGM 08OCP1 Federal Register / Vol. 86, No. 193 / Friday, October 8, 2021 / Proposed Rules addressed, could prevent proper extinguishing of a fire in the cabin, possibly resulting in damage to the helicopter and injury to the occupants. Accordingly, EASA AD 2020–0013 requires replacing affected fire extinguishers and prohibits installing an affected fire extinguisher on any helicopter. FAA’s Determination These products 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 about the unsafe condition described in its AD. The FAA is proposing this AD after evaluating all known relevant information and determining that the unsafe condition described previously is likely to exist or develop on other products. Related Service Information Under 1 CFR Part 51 The FAA reviewed Umlaut Vendor Service Bulletin Doc. No. P3VSB000001, Issue C, dated December 13, 2019 (VSB P3VSB000001). This service information specifies procedures for identifying P3HAFEX fire extinguisher P/Ns P3APP003010A and P3APP003010C, with a date of manufacture between March 2019 through July 2019, and an S/N listed in its Appendix 1, to determine if the fire extinguisher should be replaced. VSB P3VSB000001 also specifies procedures for removing, installing, and tracking affected P3HAFEX fire extinguishers. 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. jspears on DSK121TN23PROD with PROPOSALS1 Proposed AD Requirements in This NPRM This proposed AD would require removing affected fire extinguishers from service and prohibit installing affected fire extinguishers on any aircraft. Differences Between This Proposed AD and the EASA AD EASA AD 2020–0013 is issued against various model helicopters and defines an affected part, whereas this proposed AD is an appliance AD action against affected fire extinguishers because the unsafe condition exists in the appliance itself and not in the installation of the appliance on certain aircraft. EASA AD 2020–0013 identifies some helicopter models that are affected by this unsafe condition that are not identified as possibly affected in this proposed AD VerDate Sep<11>2014 16:42 Oct 07, 2021 Jkt 256001 because those model helicopters are not FAA type-certificated. Costs of Compliance The FAA estimates that this proposed AD affects 762 helicopters of U.S. Registry. Labor rates are estimated at $85 per work-hour. Based on these numbers, the FAA estimates that operators may incur the following costs in order to comply with this proposed AD. Replacing a fire extinguisher would take about 0.25 work-hour and parts would cost about $1,200 for an estimated cost of $1,221 per fire extinguisher. According to Umlaut Engineering GmbH service information, some of the costs of this proposed AD may be covered under warranty, thereby reducing the cost impact on affected individuals. The FAA does not control warranty coverage by Umlaut Engineering GmbH; accordingly, all costs are included in this 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. 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) Would not affect intrastate aviation in Alaska, and PO 00000 Frm 00017 Fmt 4702 Sfmt 4702 56233 (3) Would not have a significant economic impact, positive or negative, on a substantial number of small entities under the criteria of the Regulatory Flexibility Act. List of Subjects in 14 CFR Part 39 Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety. The Proposed Amendment Accordingly, under the authority delegated to me by the Administrator, the FAA proposes to amend 14 CFR part 39 as follows: PART 39—AIRWORTHINESS DIRECTIVES 1.

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2020-0013, dated January 29, 2020 
(EASA AD 2020-0013), to correct an unsafe condition for Airbus 
Helicopters Model AS 332 C, C1, L, L1, and L2, AS 365 N2 and N3, EC 155 
B and B1, EC 175 B, EC 225 LP, SA 330 J, and SA 365 C1, C2, C3, N, and 
N1 helicopters; Airbus Helicopters Deutschland GmbH Model EC135 P1, P2, 
P2+, P3, T1, T2, T2+, and T3, EC635 P2+, P3, T1, T2+, and T3, and MBB-
BK117 A-1, A-3, A-4, B-1, B-2, C-1, C-2, and D-2 helicopters; Leonardo 
S.p.A. Model AB139, AB 204B, AB 205 A-1, AB 212, AB 412, AB 412EP, AS-
61N, AS-61N1, AW139, AW169, and AW189 helicopters; and WSK PZL--
[Sacute]WIDNIK S.A. Model PZL W-3A and PZL W-3AS helicopters. EASA 
advises of occurrences that have been reported of a quality issue on 
certain fire extinguishers, manufactured by Umlaut Engineering GmbH 
(formerly P3 Engineering GmbH), where the spindle geometries of the 
extinguishers were found to be out of tolerance. The manufacturing 
defect identified in certain serial-numbered fire extinguisher part 
numbers (P/Ns) P3APP003010A and P3APP003010C with a manufacturing date 
of March 2019 through July 2019 inclusive, where prolonged exposure (12 
hours or more) to high temperature conditions of more than 68 [deg]C 
(154.4 [deg]F) could cause a non-detectable seizure of the spindle that 
could cause the fire extinguisher to be inoperative. This condition, if 
not

[[Page 56233]]

addressed, could prevent proper extinguishing of a fire in the cabin, 
possibly resulting in damage to the helicopter and injury to the 
occupants.
    Accordingly, EASA AD 2020-0013 requires replacing affected fire 
extinguishers and prohibits installing an affected fire extinguisher on 
any helicopter.

FAA's Determination

    These products 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 about the 
unsafe condition described in its AD. The FAA is proposing this AD 
after evaluating all known relevant information and determining that 
the unsafe condition described previously is likely to exist or develop 
on other products.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Umlaut Vendor Service Bulletin Doc. No. 
P3VSB000001, Issue C, dated December 13, 2019 (VSB P3VSB000001). This 
service information specifies procedures for identifying P3HAFEX fire 
extinguisher P/Ns P3APP003010A and P3APP003010C, with a date of 
manufacture between March 2019 through July 2019, and an S/N listed in 
its Appendix 1, to determine if the fire extinguisher should be 
replaced. VSB P3VSB000001 also specifies procedures for removing, 
installing, and tracking affected P3HAFEX fire extinguishers.
    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.

Proposed AD Requirements in This NPRM

    This proposed AD would require removing affected fire extinguishers 
from service and prohibit installing affected fire extinguishers on any 
aircraft.

Differences Between This Proposed AD and the EASA AD

    EASA AD 2020-0013 is issued against various model helicopters and 
defines an affected part, whereas this proposed AD is an appliance AD 
action against affected fire extinguishers because the unsafe condition 
exists in the appliance itself and not in the installation of the 
appliance on certain aircraft. EASA AD 2020-0013 identifies some 
helicopter models that are affected by this unsafe condition that are 
not identified as possibly affected in this proposed AD because those 
model helicopters are not FAA type-certificated.

Costs of Compliance

    The FAA estimates that this proposed AD affects 762 helicopters of 
U.S. Registry. Labor rates are estimated at $85 per work-hour. Based on 
these numbers, the FAA estimates that operators may incur the following 
costs in order to comply with this proposed AD.
    Replacing a fire extinguisher would take about 0.25 work-hour and 
parts would cost about $1,200 for an estimated cost of $1,221 per fire 
extinguisher.
    According to Umlaut Engineering GmbH service information, some of 
the costs of this proposed AD may be covered under warranty, thereby 
reducing the cost impact on affected individuals. The FAA does not 
control warranty coverage by Umlaut Engineering GmbH; accordingly, all 
costs are included in this 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.
    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) Would not affect intrastate aviation in Alaska, and
    (3) Would not have a significant economic impact, positive or 
negative, on a substantial number of small entities under the criteria 
of the Regulatory Flexibility Act.
