Flexibility Act. 

List of Subjects in 14 CFR Part 39 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

The Amendment 

Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new airworthiness 

directive: 

2021–12–08 Airbus Helicopters 

Deutschland GmbH (AHD): Amendment 

39–21595; Docket No. FAA–2021–0254; 

Project Identifier MCAI–2020–00481–R. 

(a) Effective Date 

This airworthiness directive (AD) is 

effective July 29, 2021. 

((b) Affected Airworthiness Directives 

None.

SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021–0014, 

dated January 13, 2021 (EASA AD 

2021–0014) (also referred to as the 

Mandatory Continuing Airworthiness 

Information, or the MCAI), to correct an 

unsafe condition for all Fokker Services 

B.V. Model F28 Mark 0070 and 0100 

airplanes. 

This AD was prompted by a report 

that corrosion was found on the 

horizontal flange on the front spar lower 

boom, between the rebate strap and the 

lower boom, and resulted in bulging. 

The FAA is issuing this AD to address 

corrosion on the horizontal flange, 

which could lead to reduced structural 

integrity of the wing torsion box 

structure. See the MCAI for additional 

background information. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2021–0014 specifies 

procedures for doing a detailed visual 

inspection to detect any bulging, loose, 

and missing countersunk fastener heads 

at the LH and RH outer wing lower skin 

of the front spar between wing station 

(WSTA) 10110 and WSTA 11190; and 

applicable on-condition actions. Oncondition actions include repetitive 

detailed visual inspections of the LH 

and RH outer wing lower skin, at the 

front spar between WSTA 10110 and 

WSTA 11190, if bulging between 0.5 

mm and 3 mm is found; a detailed 

visual inspection to detect corrosion at 

the front spar lower boom and rebate 

strap if any bulging, loose, or missing 

countersunk fastener head, or bulging in 

excess of 3 mm, is found; and repair of 

any corrosion damage. EASA AD 2021– 

0014 also specifies reporting inspection 

findings. 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 

This product has been approved by 

the aviation authority of another 

country, and is approved for operation 

in the United States. Pursuant to the 

FAA’s bilateral agreement with the State 

of Design Authority, the FAA has been 

notified of the unsafe condition 

described in the MCAI referenced 

above. The FAA is issuing this AD 

because the FAA evaluated all pertinent 

information and determined the unsafe 

condition exists and is likely to exist or 

develop on other products of the same 

type design. 

Requirements of This AD 

This AD requires accomplishing the 

actions specified in EASA AD 2021– 

0014 described previously, as 

incorporated by reference, except for 

any differences identified as exceptions 

in the regulatory text of this 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 certain 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 other manufacturers 

and CAAs. As a result, EASA AD 2021– 

0014 is incorporated by reference in this 

AD. This AD, therefore, requires 

compliance with EASA AD 2021–0014 

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 2021–0014 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 specified in EASA AD 

2021–0014 that is required for 

compliance with it is available at 

https://www.regulations.gov by 

searching for and locating Docket No. 

FAA–2021–0448. 

FAA’s Justification 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 


khammond on DSKJM1Z7X2PROD with RULES
Federal Register / Vol. 86, No. 119 / Thursday, June 24, 2021 / Rules and Regulations 33107 

effective in less than thirty days, upon 

a finding of good cause. 

There are currently no domestic 

operators of these products. 

Accordingly, notice and opportunity for 

prior public comment are unnecessary, 

pursuant to 5 U.S.C. 553(b)(3). In 

addition, for the foregoing reason, 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. 

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– 

2021–0448; Project Identifier MCAI– 

2021–00044–T’’ 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 Tom Rodriguez, 

Aerospace Engineer, Large Aircraft 

Section, International Validation 

Branch, FAA, 2200 South 216th St., Des 

Moines, WA 98198; telephone and fax 

206–231–3226; email Tom.Rodriguez@

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 (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 

Currently, there are no affected U.S.- 

registered airplanes. If an affected 

airplane is imported and placed on the 

U.S. Register in the future, the FAA 

provides the following cost estimates to 

comply with this AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS * 

Labor cost Parts cost Cost per 

product 

2 work-hours × $85 per hour = $170 ...................................................................................................................... $0 $170 

* Table does not include estimated costs for reporting. 

The FAA estimates that it takes about 

1 work-hour per product to comply with 

the reporting requirement in this AD. 

The average labor rate is $85 per hour. 

Based on these figures, the FAA 

estimates the cost of reporting the 

inspection results to be $85 per product. 

The FAA has received no definitive 

data on which to base the cost estimates 

for the on-condition actions and repairs 

specified in this AD. 

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 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 current valid 

OMB control number. The control 

number for the collection of information 

required by this AD is 2120–0056. The 

paperwork cost associated with this AD 

has been detailed in the Costs of 

Compliance section of this document 

and includes time for reviewing 

instructions, as well as completing and 

reviewing the collection of information. 

Therefore, all reporting associated with 

this AD is mandatory. Comments 

concerning the accuracy of this burden 

and suggestions for reducing the burden 

should be directed to Information 

Collection Clearance Officer, Federal 

Aviation Administration, 10101 

Hillwood Parkway, Fort Worth, TX 

76177–1524. 

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 

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, 

and 

(2) Will not affect intrastate aviation 

in Alaska.
