SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued AD 2021–16–02, 

Amendment 39–21663 (86 FR 46771, 

August 20, 2021) (AD 2021–16–02), for 

certain Airbus Helicopters Model 

SA330J, AS332C, AS332L, AS332L1, 

AS332L2, and EC225LP helicopters. AD 

2021–16–02 required inspecting the 

locking safety mechanism of the LH side 

stairway door handle and depending on 

the results, corrective action. AD 2021– 

16–02 also required modifying that 

locking safety mechanism. 

AD 2021–16–02 was prompted by 

EASA AD 2020–0087, dated April 15, 

2020 (EASA AD 2020–0087), issued by 

EASA, which is the Technical Agent for 

the Member States of the European 

Union, to correct an unsafe condition 

for Airbus Helicopters (AH), formerly 

Eurocopter, Eurocopter France, 

Aerospatiale, Sud Aviation, Model 

SA330J, AS332C, AS332L, AS332L1, 

AS332L2, and EC225LP helicopters, if 

equipped with an LH side stairway 

door, except helicopters modified in 

accordance with AH modification 

(MOD) 07 28281 (AS 332, EC 225) or 

MOD 07 27338 (SA 330). EASA issued 

EASA AD 2020–0087 to supersede 

EASA Emergency AD 2014–0241–E, 

dated November 4, 2014 (EASA AD 

2014–0241–E). 


lotter on DSK11XQN23PROD with RULES1
53198 Federal Register / Vol. 86, No. 184 / Monday, September 27, 2021 / Rules and Regulations 

The FAA issued AD 2021–16–02 to 

address incorrect locking of the LH side 

stairway door, which could result in an 

in-flight opening of the door and 

subsequent damage to the helicopter or 

injury to persons on the ground. See 

EASA AD 2020–0087 for additional 

background information. 

Actions Since AD 2021–16–02 Was 

Issued 

Since AD 2021–16–02 was issued, the 

FAA has determined that is necessary to 

clarify a required exception. As 

published, paragraph (h)(7) of AD 2021– 

16–02 could cause confusion with 

paragraph (h)(5) of AD 2021–16–02. 

Paragraph (h)(7) of this AD clarifies that 

the terminating action for the repetitive 

inspections as required by paragraph (2) 

of EASA AD 2020–0087 does not apply 

to this AD. The repetitive inspections as 

required by paragraph (2) of EASA AD 

2020–0087 are not required by 

paragraph (h)(5) of this AD, and 

accordingly, this AD cannot provide 

terminating action for those repetitive 

inspections. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2020–0087 requires 

repetitively inspecting the locking safety 

mechanism of the LH side stairway door 

handle for correct operation and 

depending on the results, 

reconditioning the locking safety 

mechanism or contacting the Airbus 

Helicopters Support and Services 

Department. EASA AD 2020–0087 also 

requires modifying the locking safety 

mechanism, which constitutes 

terminating action for the repetitive 

inspections. 

This material 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. 

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. 

AD Requirements 

This AD requires accomplishing the 

actions specified in EASA AD 2020– 

0087, described previously, as 

incorporated by reference, except for 

any differences identified as exceptions 

in the regulatory text of this AD and 

except as discussed under ‘‘Differences 

Between this AD and the EASA AD.’’ 

Explanation of Required Compliance 

Information 

In the FAA’s ongoing efforts to 

improve the efficiency of the AD 

process, the FAA developed a process to 

use some civil aviation authority (CAA) 

ADs as the primary source of 

information for compliance with 

requirements for corresponding FAA 

ADs. The FAA has been coordinating 

this process with manufacturers and 

CAAs. As a result, EASA AD 2020–0087 

is incorporated by reference in this FAA 

final rule. This AD, therefore, requires 

compliance with EASA AD 2020–0087 

in its entirety, through that 

incorporation, except for any differences 

identified as exceptions in the 

regulatory text of this AD. Using 

common terms that are the same as the 

heading of a particular section in EASA 

AD 2020–0087 does not mean that 

operators need comply only with that 

section. For example, where the AD 

requirement refers to ‘‘all required 

actions and compliance times,’’ 

compliance with this AD requirement is 

not limited to the section titled 

‘‘Required Action(s) and Compliance 

Time(s)’’ in the EASA AD. Service 

information referenced in EASA AD 

2020–0087 for compliance will be 

available at https://www.regulations.gov 

by searching for and locating FAA– 

2021–0785. 

Differences Between This AD and the 

EASA AD 

Where EASA AD 2020–0087 refers to 

the effective date of EASA AD 2014– 

0241–E or its effective date, this AD 

requires using the effective date of this 

AD. Where EASA AD 2020–0087 refers 

to Group 1 and 2 helicopters, this AD 

does not refer to any groups of 

helicopters. Where the service 

information referenced in EASA AD 

2020–0087 allows the pilot to perform 

the requirements of the ASB, this AD 

requires the requirements to be 

performed by a qualified mechanic. 

Where the service information 

referenced in EASA AD 2020–0087 

specifies to submit certain information 

to the manufacturer, this AD does not 

include that requirement. Where the 

service information referenced in EASA 

AD 2020–0087 specifies to discard 

certain parts, this AD requires removing 

those parts from service instead. EASA 

AD 2020–0087 requires repeating the 

inspection before next flight after each 

application of painting on the LH side 

stairway door or its external door 

handle, whereas this AD does not. 

EASA AD 2020–0087 allows a 

terminating action for the repetitive 

inspections, whereas this AD does not. 

EASA AD 2020–0087 requires 

contacting the Airbus Helicopters 

Support and Services Department if it is 

impossible to recondition the locking 

safety mechanism by moving the door 

handle, whereas this AD requires, before 

further flight, accomplishing paragraph 

(5) of EASA AD 2020–0087 or 

accomplishing corrective action using a 

method approved by the Manager, 

International Validation Branch, FAA. 

The Manager’s approval letter must 

specifically refer to this AD. 

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. 

This AD clarifies an exception in AD 

2021–16–02 that could affect 

compliance and the public was 

previously provided opportunity for 

comment on the costs of the AD and 

required actions. 

Accordingly, notice and opportunity 

for prior public comment are 

unnecessary 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 forgo notice and 

comment. 

Comments Invited 

The FAA invites you to send any 

written relevant data, views, or 

arguments about this AD. Send your 

comments to an address listed under 

ADDRESSES. Include ‘‘Docket No. FAA– 

2021–0785; Project Identifier AD–2021– 

00989–R’’ at the beginning of your 

comments. The most helpful comments 

reference a specific portion of the AD, 

explain the reason for any 

recommended change, and include 

supporting data. The FAA will consider 

all comments received by the closing 


lotter on DSK11XQN23PROD with RULES1
Federal Register / Vol. 86, No. 184 / Monday, September 27, 2021 / Rules and Regulations 53199 

date and may amend this AD 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 AD. 

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 Hal Jensen, Aerospace 

Engineer, Operational Safety Branch, 

FAA, 950 L’Enfant Plaza N SW, 

Washington, DC 20024; telephone (202) 

267–9167; email hal.jensen@faa.gov. 

Any commentary that the FAA receives 

that is not specifically designated as CBI 

will be placed in the public docket for 

this rulemaking. 

Regulatory Flexibility Act (RFA) 

The requirements of the 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 notice and comment, RFA 

analysis is not required. 

Costs of Compliance 

The FAA estimates that this AD 

affects 37 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. 

Inspecting the operation of the 

locking safety mechanism on the LH 

side stairway door handle takes about 

0.1 work-hour for an estimated cost of 

$9 per helicopter and $333 for the U.S. 

fleet. Moving the external door handle 

from the ‘‘Locked’’ to the ‘‘Unlocked’’ 

position to determine if the safety 

mechanism on the LH side stairway 

door handle can lock automatically 

takes about 0.5 work-hour for an 

estimated cost of $43 per helicopter. 

Modifying the locking safety mechanism 

on the LH side stairway door handle 

takes about 8 work-hours and parts cost 

about $5,000 for an estimated cost of 

$5,680 per helicopter. 

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 AD 

would not have federalism implications 

under Executive Order 13132. This 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 above, I 

certify this regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

and 

(2) Will not affect intrastate aviation 

in Alaska.

accordance with, EASA AD 2020–0087. 

(h) Exceptions to EASA AD 2020–0087 

(1) Where EASA AD 2020–0087 refers to 

November 6, 2014 (the effective date of EASA 

AD 2014–0241–E, dated November 4, 2014) 

or its effective date, this AD requires using 

the effective date of this AD. 

(2) Where EASA AD 2020–0087 refers to 

Group 1 and Group 2 helicopters, this AD 

does not refer to any groups of helicopters. 

(3) Where the service information 

referenced in EASA AD 2020–0087 permits 

certain actions to be performed by a 

mechanical engineering technician or pilot, 

this AD requires that the actions be 

performed by a qualified mechanic. 

(4) Where the service information 

referenced in EASA AD 2020–0087 specifies 


lotter on DSK11XQN23PROD with RULES1
53200 Federal Register / Vol. 86, No. 184 / Monday, September 27, 2021 / Rules and Regulations 

to discard certain parts, this AD requires 

removing those parts from service. 

(5) While paragraph (2) of EASA AD 2020– 

0087 requires actions before next flight after 

each application of painting on the LH side 

stairway door or its external door handle, 

those actions are not required by this AD. 

(6) Where paragraph (3) of EASA AD 2020–

Airbus Helicopters Support and Services 

Department if it is impossible to recondition 

the locking safety mechanism by moving the 

door handle, this AD requires moving the 

external door handle from the ‘‘Locked’’ to 

the ‘‘Unlocked’’ position to determine if the 

safety mechanism can lock automatically. If 

the safety mechanism does not lock 

automatically, this AD requires, before 

further flight accomplishing paragraph (5) of 

EASA AD 2020–0087 or accomplishing 

corrective action using a method approved by 

the Manager, International Validation 

Branch, FAA. The Manager’s approval letter 

must specifically refer to this AD.

0087 identifies the modification as required 

by paragraph (4) of EASA AD 2020–0087 as 

terminating action for the repetitive 

inspections as required by paragraph (2) of 

EASA AD 2020–0087 for that helicopter, the 

terminating action for the repetitive 

inspections as required by paragraph (2) of 

EASA AD 2020–0087 does not apply to this 

AD. 

(8) This AD does not mandate compliance 

with the ‘‘Remarks’’ section of EASA AD 

2020–0087. 

(i) No Reporting Requirement 

Although the service information 

referenced in EASA AD 2020–0087 specifies 

to submit certain information to the 

manufacturer, this AD does not include that 

requirement. 

(j) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, International Validation 

Branch, FAA, has the authority to approve 

AMOCs for this AD, if requested using the
