VerDate Sep<11>2014 16:24 Jun 04, 2021 Jkt 253001 30153 Leonardo S.p.a. Model AB139 and AW139 helicopters with 3-stretcher kit part number 139084–501 installed by a certain supplemental type certificate (STC). EASA advises that a design deficiency was identified, affecting the primary stretcher unit, part number 002095–502, of the 3-stretcher kit part number 139084–501. This condition, if not addressed, could lead, in case of an emergency landing, to failure of the primary stretcher of the 3-stretcher kit, possibly resulting in injury to helicopter occupants. Accordingly, EASA AD 2021–0095 requires installing a placard on the primary stretcher stating a limitation of 61 kg (134.5 lbs) for the maximum allowable weight of the occupant on the primary stretcher. EASA considers its AD an interim action and states that further AD action may follow. Although EASA AD 2021–0095 applies to Leonardo S.p.a. Model AB139 and AW139 helicopters with 3-stretcher kit part number 139084–501 installed by a certain STC, this AD applies to helicopters with an affected part installed instead. 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 about the unsafe condition described in its AD. The FAA is issuing this AD after evaluating all known relevant information and determining that the unsafe condition described previously is likely to exist or develop on other helicopters of these same type designs. Related Service Information Under 1 CFR Part 51 The FAA reviewed Aerolite Alert Service Bulletin ASB–21–006, dated March 16, 2021. This service information specifies procedures for installing a weight limit placard on the primary stretcher unit of the 3-stretcher kit. 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. Background AD Requirements EASA, which is the Technical Agent for the Member States of the European Union, has issued EASA AD 2021–0095, dated March 31, 2021 (EASA AD 2021– 0095), to correct an unsafe condition for This AD requires accomplishing the actions specified in the service information already described, except as discussed under ‘‘Differences Between the AD and the EASA AD.’’ PO 00000 Frm 00003 Fmt 4700 Sfmt 4700 E:\FR\FM\07JNR1.SGM 07JNR1 30154 Federal Register / Vol. 86, No. 107 / Monday, June 7, 2021 / Rules and Regulations Differences Between This AD and the EASA AD EASA AD 2021–0095 requires operators to ‘‘inform all affected flight crew and medical crew members’’ of the placard installation on the primary stretcher. However, this AD would not specifically require that action. Interim Action The FAA considers this AD to be an interim action. If final action is later identified, the FAA might consider further rulemaking then. Justification for Immediate Adoption and Determination of the Effective Date Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 U.S.C. 551 et seq.) authorizes agencies to dispense with notice and comment procedures for rules when the agency, for ‘‘good cause,’’ finds that those procedures are ‘‘impracticable, unnecessary, or contrary to the public interest.’’ Under this section, an agency, upon finding good cause, may issue a final rule without providing notice and seeking comment prior to issuance. Further, section 553(d) of the APA authorizes agencies to make rules effective in less than thirty days, upon a finding of good cause. 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 foregoing notice and comment prior to adoption of this rule because a design deficiency which affects the primary stretcher unit of the 3-stretcher kit, if not addressed, could lead, in case of an emergency landing, to failure of the primary stretcher, possibly resulting in injury to helicopter occupants. Accordingly, notice and opportunity for prior public comment are impracticable and contrary to the public interest pursuant to 5 U.S.C. 553(b)(3)(B). In addition, the FAA finds that good cause exists pursuant to 5 U.S.C. 553(d) for making this amendment effective in less than 30 days, for the same reasons the FAA found good cause to forego notice and comment. Comments Invited The FAA invites you to send any written data, views, or arguments about this final rule. Send your comments to an address listed under ADDRESSES. Include ‘‘Docket No. FAA–2021–0452; Project Identifier MCAI–2021–00388–R’’ at the beginning of your comments. The most helpful comments reference a specific portion of the final rule, explain the reason for any recommended change, and include supporting data. The FAA will consider all comments received by the closing date and may amend this final rule because of those comments. Except for Confidential Business Information (CBI) as described in the following paragraph, and other information as described in 14 CFR 11.35, the FAA will post all comments received, without change, to https:// www.regulations.gov, including any personal information you provide. The agency will also post a report summarizing each substantive verbal contact received about this final rule. Confidential Business Information CBI is commercial or financial information that is both customarily and actually treated as private by its owner. Under the Freedom of Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public disclosure. If your comments responsive to this AD contain commercial or financial information that is customarily treated as private, that you actually treat as private, and that is relevant or responsive to this AD, it is important that you clearly designate the submitted comments as CBI. Please mark each page of your submission containing CBI as ‘‘PROPIN.’’ The FAA will treat such marked submissions as confidential under the FOIA, and they will not be placed in the public docket of this AD. Submissions containing CBI should be sent to Andrea Jimenez, Aerospace Engineer, COS Program Management Section, Operational Safety Branch, Compliance & Airworthiness Division, FAA, 1600 Stewart Ave., Mail Stop: Room 410, Westbury, NY 11590; phone: (516) 228– 7330; email: andrea.jimenez@faa.gov. Any commentary that the FAA receives which is not specifically designated as CBI will be placed in the public docket for this rulemaking. Regulatory Flexibility Act The requirements of the Regulatory Flexibility Act (RFA) do not apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt a rule without prior notice and comment. Because the FAA has determined that it has good cause to adopt this rule without prior notice and comment, RFA analysis is not required. Costs of Compliance The FAA estimates that this AD affects 129 helicopters of U.S. Registry. Labor rates are estimated at $85 per work-hour. Based on these numbers, the FAA estimates the following costs to comply with this AD. ESTIMATED COSTS FOR REQUIRED ACTIONS Labor cost Parts cost Cost per product Cost on U.S. operators 1 work-hour × $85 per hour = $85 .............................................................................................. $10 $95 $12,255 khammond on DSKJM1Z7X2PROD with RULES The FAA has included all known costs in its cost estimate. According to the manufacturer, however, some of the costs of this AD may be covered under warranty, thereby reducing the cost impact on affected operators. 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 VerDate Sep<11>2014 16:24 Jun 04, 2021 Jkt 253001 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 00004 Fmt 4700 Sfmt 4700 unsafe condition that is likely to exist or develop on products 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. E:\FR\FM\07JNR1.SGM 07JNR1 Federal Register / Vol. 86, No. 107 / Monday, June 7, 2021 / Rules and Regulations For the reasons discussed, I certify that this AD: (1) Is not a ‘‘significant regulatory action’’ under Executive Order 12866, and (2) Will not affect intrastate aviation in Alaska.

SUPPLEMENTARY INFORMATION:

Background

    EASA, which is the Technical Agent for the Member States of the 
European Union, has issued EASA AD 2021-0095, dated March 31, 2021 
(EASA AD 2021-0095), to correct an unsafe condition for Leonardo S.p.a. 
Model AB139 and AW139 helicopters with 3-stretcher kit part number 
139084-501 installed by a certain supplemental type certificate (STC). 
EASA advises that a design deficiency was identified, affecting the 
primary stretcher unit, part number 002095-502, of the 3-stretcher kit 
part number 139084-501. This condition, if not addressed, could lead, 
in case of an emergency landing, to failure of the primary stretcher of 
the 3-stretcher kit, possibly resulting in injury to helicopter 
occupants.
    Accordingly, EASA AD 2021-0095 requires installing a placard on the 
primary stretcher stating a limitation of 61 kg (134.5 lbs) for the 
maximum allowable weight of the occupant on the primary stretcher. EASA 
considers its AD an interim action and states that further AD action 
may follow. Although EASA AD 2021-0095 applies to Leonardo S.p.a. Model 
AB139 and AW139 helicopters with 3-stretcher kit part number 139084-501 
installed by a certain STC, this AD applies to helicopters with an 
affected part installed instead.

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 about the 
unsafe condition described in its AD. The FAA is issuing this AD after 
evaluating all known relevant information and determining that the 
unsafe condition described previously is likely to exist or develop on 
other helicopters of these same type designs.

Related Service Information Under 1 CFR Part 51

    The FAA reviewed Aerolite Alert Service Bulletin ASB-21-006, dated 
March 16, 2021. This service information specifies procedures for 
installing a weight limit placard on the primary stretcher unit of the 
3-stretcher kit.
    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 accomplishing the actions specified in the service 
information already described, except as discussed under ``Differences 
Between the AD and the EASA AD.''

[[Page 30154]]

Differences Between This AD and the EASA AD

    EASA AD 2021-0095 requires operators to ``inform all affected 
flight crew and medical crew members'' of the placard installation on 
the primary stretcher. However, this AD would not specifically require 
that action.

Interim Action

    The FAA considers this AD to be an interim action. If final action 
is later identified, the FAA might consider further rulemaking then.

Justification for Immediate Adoption and Determination of the Effective 
Date

    Section 553(b)(3)(B) of the Administrative Procedure Act (APA) (5 
U.S.C. 551 et seq.) authorizes agencies to dispense with notice and 
comment procedures for rules when the agency, for ``good cause,'' finds 
that those procedures are ``impracticable, unnecessary, or contrary to 
the public interest.'' Under this section, an agency, upon finding good 
cause, may issue a final rule without providing notice and seeking 
comment prior to issuance. Further, section 553(d) of the APA 
authorizes agencies to make rules effective in less than thirty days, 
upon a finding of good cause.
    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 foregoing notice and comment prior to adoption of this rule 
because a design deficiency which affects the primary stretcher unit of 
the 3-stretcher kit, if not addressed, could lead, in case of an 
emergency landing, to failure of the primary stretcher, possibly 
resulting in injury to helicopter occupants. Accordingly, notice and 
opportunity for prior public comment are impracticable and contrary to 
the public interest pursuant to 5 U.S.C. 553(b)(3)(B).
    In addition, the FAA finds that good cause exists pursuant to 5 
U.S.C. 553(d) for making this amendment effective in less than 30 days, 
for the same reasons the FAA found good cause to forego notice and 
comment.

Comments Invited

    The FAA invites you to send any written data, views, or arguments 
about this final rule. Send your comments to an address listed under 
ADDRESSES. Include ``Docket No. FAA-2021-0452; Project Identifier MCAI-
2021-00388-R'' at the beginning of your comments. The most helpful 
comments reference a specific portion of the final rule, explain the 
reason for any recommended change, and include supporting data. The FAA 
will consider all comments received by the closing date and may amend 
this final rule because of those comments.
    Except for Confidential Business Information (CBI) as described in 
the following paragraph, and other information as described in 14 CFR 
11.35, the FAA will post all comments received, without change, to 
https://www.regulations.gov, including any personal information you 
provide. The agency will also post a report summarizing each 
substantive verbal contact received about this final rule.

Confidential Business Information

    CBI is commercial or financial information that is both customarily 
and actually treated as private by its owner. Under the Freedom of 
Information Act (FOIA) (5 U.S.C. 552), CBI is exempt from public 
disclosure. If your comments responsive to this AD contain commercial 
or financial information that is customarily treated as private, that 
you actually treat as private, and that is relevant or responsive to 
this AD, it is important that you clearly designate the submitted 
comments as CBI. Please mark each page of your submission containing 
CBI as ``PROPIN.'' The FAA will treat such marked submissions as 
confidential under the FOIA, and they will not be placed in the public 
docket of this AD. Submissions containing CBI should be sent to Andrea 
Jimenez, Aerospace Engineer, COS Program Management Section, 
Operational Safety Branch, Compliance & Airworthiness Division, FAA, 
1600 Stewart Ave., Mail Stop: Room 410, Westbury, NY 11590; phone: 
(516) 228-7330; email: [email protected]. Any commentary that the 
FAA receives which is not specifically designated as CBI will be placed 
in the public docket for this rulemaking.

Regulatory Flexibility Act

    The requirements of the Regulatory Flexibility Act (RFA) do not 
apply when an agency finds good cause pursuant to 5 U.S.C. 553 to adopt 
a rule without prior notice and comment. Because the FAA has determined 
that it has good cause to adopt this rule without prior notice and 
comment, RFA analysis is not required.

Costs of Compliance

    The FAA estimates that this AD affects 129 helicopters of U.S. 
Registry. Labor rates are estimated at $85 per work-hour. Based on 
these numbers, the FAA estimates the following costs to comply with 
this AD.

                                      Estimated Costs for Required Actions
----------------------------------------------------------------------------------------------------------------
                                                                                    Cost per       Cost on U.S.
                          Labor cost                              Parts cost        product         operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $85 per hour = $85.............................             $10              $95          $12,255
----------------------------------------------------------------------------------------------------------------

    The FAA has included all known costs in its cost estimate. 
According to the manufacturer, however, some of the costs of this AD 
may be covered under warranty, thereby reducing the cost impact on 
affected operators.

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

    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.

[[Page 30155]]

    For the reasons discussed, I certify that this AD:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866, and
    (2) Will not affect intrastate aviation in Alaska.
