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.’’ 


khammond on DSKJM1Z7X2PROD with RULES
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

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.
