delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows:

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: 

2021–12–04 Fokker Services B.V.: 

Amendment 39–21591; Docket No. 

FAA–2021–0448; Project Identifier 

MCAI–2021–00044–T. 

(a) Effective Date 

This airworthiness directive (AD) becomes 

effective July 9, 2021.

(e) Reason 

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

compliance times specified, unless already 

done. 

(g) Requirements 

Except as specified in paragraph (h) of this

effective date of this AD. 

(2) Where paragraph (2) of EASA AD 2021– 

0014 requires additional actions for bulging 

‘‘between 0.5 mm and 3 mm,’’ this AD 

requires those additional actions for bulging 

0.5 mm or more and 3.0 mm or less. 

(3) The ‘‘Remarks’’ section of EASA AD 

2021–0014 does not apply to this AD. 

(4) Paragraph (5) of EASA AD 2021–0014 

specifies to report inspection results within 

a certain compliance time. For this AD, 

report the inspection results of each 

inspection accomplished in this AD at the 

applicable time specified in paragraph 

(h)(4)(i) or (ii) of this AD. 

(i) If the inspection was done on or after 

the effective date of this AD: Submit the 

report within 30 days after the inspection. 

(ii) If the inspection was done before the 

effective date of this AD: Submit the report 

within 30 days after the effective date of this 

AD.

The following provisions also apply to this 

AD: 

(1) Alternative Methods of Compliance 

(AMOCs): The Manager, Large Aircraft 

Section, International Validation Branch,

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all

connector that occurred during 

production electrical tests. This AD 

requires replacing certain wire harness 

trim connector backshells (backshells), 

as specified in a European Union 

Aviation Safety Agency (EASA) AD, 

which is incorporated by reference. The 

FAA is issuing this AD to address the 

unsafe condition on these products. 

DATES: This AD is effective July 29, 

2021. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of July 29, 2021.

SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2019–0198, 

dated August 15, 2019 (EASA AD 2019– 

0198), to correct an unsafe condition for 

all Airbus Helicopters Deutschland 

GmbH (AHD), formerly Eurocopter 

Deutschland GmbH, Model MBB–BK117 

D–2 helicopters. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to Airbus Helicopters 

Deutschland GmbH Model MBB–BK 117 

D–2 helicopters. The NPRM published 

in the Federal Register on April 2, 2021 

(86 FR 17322). The NPRM was 

prompted by a short circuit in a yaw 

trim actuator connector that occurred 

during production electrical tests. 

Subsequent investigations determined 

that a sharp edge in the backshell 

damaged the wiring insulation. The 

NPRM proposed to require replacing 

certain backshells, as specified in an 

EASA AD. 

The FAA is issuing this AD to address 

an unsafe condition that could result in 

yaw or pitch trim runaway and 

subsequent loss of control of the 

helicopter. See EASA AD 2019–0198 for 

additional background information. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA gave the public the 

opportunity to participate in developing 

this final rule. The FAA received 

comments from one commenter; 

however, none of the comments 

requested a change to the requirements 

proposed by the NPRM or the 

determination of the cost to the public. 

Conclusion 

The FAA reviewed the relevant data, 

considered the comments received, and 

determined that air safety and the 

public interest require adopting this 

final rule as proposed. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2019–0198 specifies 

replacing backshells part number (P/N) 

M85049/90–13W02 if manufactured by 

AMPHENOL or if the manufacturer is 

unknown (affected part) with backshells 

P/N M85049/90–13W02 not 

manufactured by AMPHENOL 

(serviceable part). EASA AD 2019–0198 

also prohibits the (re-)installation of an 

affected part. 

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. 

Differences Between This AD and the 

EASA AD 

EASA AD 2019–0198 applies to all 

Model MBB–BK117 D–2 helicopters, 

whereas this AD applies to that model 

helicopter with an affected part 

installed instead. EASA AD 2019–0198 

requires replacing each affected part 

with a serviceable part within 9 months, 

whereas this AD requires that 

replacement within 30 hours time-inservice instead. 

Costs of Compliance 

The FAA estimates that this AD 

affects 30 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. 

Replacing each backshell takes about 

8 work-hours and parts cost $220, for an 

estimated cost of $900 per backshell. 

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 

(3) Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities 

under the criteria of the Regulatory 

Flexibility Act.
