AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2003–25– 

01 which applied to certain Eurocopter 

France (now Airbus Helicopters) Models 

AS332C, AS332C1, AS332L, AS332L1, 

AS350B, AS350BA, AS350B1, 

AS350B2, AS350B3, AS350D, AS355E, 

AS355F, AS355F1, AS355F2, and 

AS355N helicopters. AD 2003–25–01 

required modifying and re-identifying 

the hoist operator control unit and 

replacing certain fuses. This AD was 

prompted by the identification of 

multiple errors in the applicable service 

information for the AS350-series and 

AS355-series helicopters and of other 

needed changes. This AD retains certain 

requirements of AD 2003–25–01, revises 

the applicability, and requires using 

corrected service information. This AD 

also requires reporting certain 

information and prohibits the 

installation of an affected hoist until the 

required actions are accomplished. The 

FAA is issuing this AD to address the 

unsafe condition on these products. 

DATES: This AD is effective August 19, 

2021. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of August 19, 2021. 

The Director of the Federal Register

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2003–25–01, 

Amendment 39–13384 (68 FR 69596, 

December 15, 2003) (AD 2003–25–01), 

for Eurocopter France (now Airbus 

Helicopters) Model AS332C, C1, L, and 

L1, AS350B, BA, B1, B2, B3, and D, and 

AS355E, F, F1, F2, and N helicopters 

with a Breeze 300 pound electric hoist 

(hoist) and hoist operator control unit 

26M part number (P/N) 350A63–1136– 

00 or 350A63–1136–01, and hoist 

electric box 91M P/N 332A67–2875–00, 

installed. The NPRM published in the 

Federal Register on April 28, 2021 (86 

FR 22363). In the NPRM, the FAA 

proposed to require modifying and reidentifying the hoist operator control 

unit, replacing the fuses, and 

performing a functional test of the hoist 

operation and the emergency jettison 

controls. The NPRM also proposed to 

require reporting certain information 

and prohibit the installation of an 

affected hoist until the required actions 

are accomplished. 

The NPRM was prompted by EASA 

AD 2019–0228, dated September 12, 

2019 (EASA AD 2019–0228) to 

supersede DGAC AD 2002–585(A), 

dated November 27, 2002 (DGAC AD 

2002–585(A)), issued by DGAC, which 

is the aviation authority for France. 

EASA, which is the Technical Agent for 

the Member States of the European 

Union, issued EASA AD 2019–0228 to 

correct an unsafe condition for Airbus 

Helicopters (AH), formerly Eurocopter, 

Eurocopter France, Aerospatiale Model 

AS 350 B, AS 350 BA, AS 350 BB, AS 

350 B1, AS 350 B2, AS 350 B3, AS 350 

D, AS 355 E, AS 355 F, AS 355 F1, AS 

355 F2, and AS 355 N helicopters. 

EASA advises that Airbus Helicopters 

identified translation errors in the 

service information required for 

compliance by DGAC AD 2002–585(A). 

Airbus Helicopters was also informed 

that there could be helicopters modified 

by that service information with 

incorrect installations. Prompted by 

these findings, Airbus Helicopters 

revised the related service information. 

Therefore, EASA issued EASA AD 

2019–0228 to require modifying and reidentifying the hoist operator control 

unit, replacing the fuses, and 

performing a functional test of the hoist 

operation and the emergency jettison 

controls as intended by DGAC AD 

2002–585(A) with the revised service 

information. EASA AD 2019–0228 also 

requires reporting certain information to 

Airbus Helicopters and prohibits the 

installation of an affected part on any 

helicopter unless it has been modified. 

The NPRM also retains the 

requirements from AD 2003–25–01 for 

Model AS332C, C1, L, and L1 

helicopters with a certain hoist and 

hoist box installed, based on DGAC AD 

2002–584(A), dated November 27, 2002. 

Additionally, since the FAA issued 

AD 2003–25–01, the FAA discovered 

that the applicability needed to be 

revised. This AD revises the 

applicability by distinguishing the hoist 

box installations by P/N, clarifying that 

Airbus Helicopters service information 

refers to a hoist box as a hoist operator’s 

control unit, adding TRW, Lucas, and 

Air Equipement hoists for affected 

Model AS350-series and AS355-series 

helicopters, and adding an exception for 

affected helicopters to exclude those 

with a certain modification (MOD) 

installed.

37232 Federal Register / Vol. 86, No. 133 / Thursday, July 15, 2021 / Rules and Regulations 

Lastly, since the FAA issued AD 

2003–25–01, Eurocopter France changed 

its name to Airbus Helicopters. This AD 

reflects that change and updates the 

contact information to obtain service 

documentation. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the NPRM or on the determination of 

the costs. 

Conclusion 

These helicopters have been approved 

by both the authority of France and 

EASA and are approved for operation in 

the United States. Pursuant to the FAA’s 

bilateral agreement with France and the 

European Union, DGAC and EASA have 

notified the FAA about the unsafe 

condition described in the ADs issued 

by each authority. The FAA reviewed 

the relevant data and determined that 

air safety requires adopting this AD as 

proposed. Accordingly, the FAA is 

issuing this AD to address the unsafe 

condition on these helicopters. With the 

exception of the minor editorial change 

of adding, ‘‘With a’’ in paragraph 

(c)(1)(ii) of this AD, this AD is adopted 

as proposed in the NPRM. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed Airbus Helicopters 

Alert Service Bulletin (ASB) No. 

25.00.71, Revision 2, dated May 14, 

2019 (ASB 25.00.71 Rev 2), Airbus 

Helicopters ASB No. 25.00.79, Revision 

3, dated September 24, 2019 (ASB 

25.00.79 Rev 3), and Eurocopter ASB 

No. 25.01.18, dated November 12, 2002 

(ASB 25.01.18). ASB 25.00.71 Rev 2 

applies to Model AS355-series 

helicopters, ASB 25.00.79 Rev 3 applies 

to Model AS350-series helicopters, and 

ASB 25.01.18 applies to Model AS332- 

series helicopters. ASB 25.00.71 Rev 2 

and ASB 25.00.79 Rev 3 specify 

procedures to install MOD 07 3190, 

which consists of eliminating resistor 

27M in the hoist operator’s control unit 

26M and replacing the 2.5A quickresponse fuses on the Honeywell unit at 

30 alpha or 21 delta for Model AS350- 

series helicopters or on the distribution 

panel 10 alpha for Model 355-series 

helicopters. ASB 25.00.71 Rev 2 and 

ASB 25.00.79 Rev 3 also specify 

reporting certain information to Airbus 

Helicopters. ASB 25.01.18 specifies 

procedures to install MOD 332PCS 78 

288, which consists of eliminating 

resistor 81M in hoist box 91M and reidentifying the hoist box as 332P67– 

2894–01, –02, –03, or –04, depending on 

which electrical wiring assembly is 

installed in the helicopter. 

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. 

Other Related Service Information 

The FAA also reviewed Airbus 

Helicopters ASB No. 25.00.71, Revision 

1, dated May 21, 2014 (ASB 25.00.71 

Rev 1), and ASB No. 25.00.79, Revision 

1, dated May 21, 2014 (ASB 25.00.79 

Rev 1) and Revision 2 (ASB 25.00.79 

Rev 2), dated May 14, 2019. 

ASB 25.00.71 Rev 1 specifies the same 

actions as ASB 25.00.71 Rev 2, except 

ASB 25.00.71 Rev 2 provides a reminder 

that MOD 07 3190 is mandatory and 

adds a reporting response form. ASB 

25.00.79 Rev 1 and ASB 25.00.79 Rev 2 

specify the same actions as ASB 

25.00.79 Rev 3, except ASB 25.00.79 

Rev 2 provides a reminder that MOD 07 

3190 is mandatory and adds a reporting 

response form and ASB 25.00.79 Rev 3 

adds Model AS350L1 to the effectivity. 

Differences Between This AD and the 

EASA AD 

EASA AD 2019–0228 applies to 

Model AS350BB helicopters, whereas 

this AD does not because that model is 

not FAA type-certificated. EASA AD 

2019–0228 requires modifying affected 

parts within 100 flight hours or 2 

months, whichever occurs first, whereas 

this AD requires these actions before 

next flight involving a hoist operation 

for Model AS350-series and AS355- 

series helicopters instead. 

Costs of Compliance 

The FAA estimates that this AD 

affects up to 977 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 AD. 

Modifying and re-identifying the hoist 

operator control unit, replacing the 

fuses, and functionally testing the hoist 

operation and the emergency jettison 

controls takes about 4 work hours and 

parts cost about $20 for an estimated 

cost of $360 per helicopter and up to 

$351,720 for the U.S. fleet. 

For Model AS350-series and AS355- 

series helicopters, reporting information 

takes about 1 work-hour for an 

estimated cost of $85 per helicopter and 

up to $82,195 for the U.S. fleet. 

Paperwork Reduction Act 

A federal agency may not conduct or 

sponsor, and a person is not required to 

respond to, nor shall a person be subject 

to a penalty for failure to comply with 

a collection of information subject to the 

requirements of the Paperwork 

Reduction Act unless that collection of 

information displays a currently valid 

OMB Control Number. The OMB 

Control Number for this information 

collection is 2120–0056. Public 

reporting for this collection of 

information is estimated to take 

approximately 1 hour per response, 

including the time for reviewing 

instructions, searching existing data 

sources, gathering and maintaining the 

data needed, and completing and 

reviewing the collection of information. 

All responses to this collection of 

information are mandatory. Send 

comments regarding this burden 

estimate or any other aspect of this 

collection of information, including 

suggestions for reducing this burden to:

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. 

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

Establishment and Modification of 

Class E Airspace; Williston Basin, ND 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This action establishes a Class 

E airspace area, designated as an 

extension to a Class D or Class E surface 

area, at Williston Basin International 

Airport, Williston, ND. This action also 

modifies the Class E airspace extending 

upward from 700 feet above the surface. 

The airspace modifications support the 

establishment of new instrument 

procedures for runways 04 and 22. This 

action also updates the geographic 

coordinates in the Class E2 and Class E5 

text headers. The airspace supports 

instrument flight rules (IFR) operations 

at the airport. 

DATES: Effective 0901 UTC, October 7, 

2021. The Director of the Federal 

Register approves this incorporation by 

reference action under 1 CFR part 51,

SUPPLEMENTARY INFORMATION: 

Authority for This Rulemaking 

The FAA’s authority to issue rules 

regarding aviation safety is found in 

Title 49 of the United States Code. 

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. This rulemaking is 

promulgated under the authority 

described in Subtitle VII, Part A, 

Subpart I, Section 40103. Under that 

section, the FAA is charged with 

prescribing regulations to assign the use 

of airspace necessary to ensure the 

safety of aircraft and the efficient use of 

airspace. This regulation is within the 

scope of that authority as it establishes 

Class E and modifies Class E airspace at 

Williston Basin International Airport, 

Williston, ND, to ensure the safety and 

management of IFR operations at the 

airport. 

History 

The FAA published a notice of 

proposed rulemaking in the Federal 

Register (86 FR 21672; April 23, 2021) 

for Docket No. FAA–2021–0292 to 

modify the Class E airspace at Williston 

Basin International Airport, Williston, 

ND. Interested parties were invited to 

participate in this rulemaking effort by 

submitting written comments on the 

proposal to the FAA. No comments 

were received. 

After the publication of the NPRM, 

the FAA determined that Class E4 

airspace should be established versus 

modifying the Class E2 airspace. This 

action corrects the NPRM by 

establishing Class E4 airspace. This 

airspace area is designed to contain IFR 

aircraft descending below 1,000 feet 

above the surface on the VOR RWY 22 

approach. The new Class E4 area is 

identical to the Class E2 modification 

that was proposed in the NPRM. The 

airspace is described as ‘‘That airspace 

extending upward from the surface 

within 2.4 miles each side of the 045° 

bearing from the airport, extending from 

the Class E2’s 4.2-mile radius to 6.8 

miles northeast of the airport.’’ 

Class E2, E4, and E5 airspace 

designations are published in 

paragraphs 6002, 6004, and 6005 of 

FAA Order 7400.11E, dated July 21, 

2020, and effective September 15, 2020, 

which is incorporated by reference in 14 

CFR 71.1. The Class E airspace 

designation listed in this document will 

be published subsequently in the Order. 

Availability and Summary of 

Documents for Incorporation by 

Reference 

This document amends FAA Order 

7400.11E, Airspace Designations and 

Reporting Points, dated July 21, 2020, 

and effective September 15, 2020. FAA 

Order 7400.11E is publicly available as 

listed in the ADDRESSES section of this 

document. FAA Order 7400.11E lists 

Class A, B, C, D, and E airspace areas, 

air traffic service routes, and reporting 

points. 

The Rule 

This amendment to 14 CFR part 71 

establishes a Class E airspace area, 

designated as an extension to a Class D 

or Class E surface area, at Williston 

Basin International Airport, Williston, 

ND. This airspace area is established 

northeast of the airport and is designed 

to contain arriving IFR aircraft 

descending below 1,000 feet above the 

surface on the VOR RWY 22 approach. 

Additionally, this action modifies the 

Class E airspace extending upward from 

700 feet above the surface. This airspace 

is designed to contain arriving IFR 

aircraft descending below 1,500 feet 

above the surface and departing IFR 

aircraft until reaching 1,200 feet above 

the surface. An area northeast and
