SUPPLEMENTARY INFORMATION: 

Background 

The EASA, which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2020–0084, dated April 3, 2020 (EASA 

AD 2020–0084) (also referred to as the 

Mandatory Continuing Airworthiness 

Information, or the MCAI), to correct an 

unsafe condition for all Airbus 

Helicopters Deutschland GmbH Model 

MBB–BK117 D–2 helicopters. Although 

EASA AD 2020–0084 applies to all 

Model MBB–BK117 D–2 helicopters, 

this AD applies to helicopters with an 

affected part installed instead. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain Model MBB–BK117 D– 

2 helicopters. The NPRM published in 

the Federal Register on March 8, 2021 

(86 FR 13234). The NPRM was 

prompted by reports that collective 

lever switch units having certain part 

numbers did not have retaining rings 

installed in the cable cut switch guard. 

The NPRM proposed to require 

inspecting certain collective lever 

switch units for discrepancies (missing 

retaining rings, incorrectly installed 

retaining rings, and a missing axis in the 

cable cut switch guard), doing all 

applicable corrective actions, and 

marking affected parts. 

The cable cut switch guard has an 

axis that holds, and allows the guard to 

turn over, the cable cut switch. This axis 

is secured with two retaining rings and 

if both retaining rings are missing, the 

axis can move out. The FAA is issuing 

this AD to address this condition, which 

could cause inadvertent activation of 

the rescue hoist cable cut function, 

resulting in personal injury. See the 

MCAI 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 no 

comments on the NPRM or on the 

determination of the cost to the public. 

Conclusion 

The FAA reviewed the relevant data 

and determined that air safety and the 

public interest require adopting this 

final rule as proposed, except for minor 

editorial changes and an update to 

paragraph (j)(1) of this AD. The FAA has 

determined that these minor changes: 

• Are consistent with the intent that 

was proposed in the NPRM for 

addressing the unsafe condition; and 

• Do not add any additional burden 

upon the public than was already 

proposed in the NPRM. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2020–0084 specifies 

procedures for inspecting collective 

lever switch units having certain part 

numbers for discrepancies, applicable 

corrective actions, and marking affected 

parts. Discrepancies include missing 

retaining rings, incorrectly installed 

retaining rings, and a missing axis in the 

cable cut switch guard. Corrective 

actions include installing missing 

retaining rings, adjusting retaining rings 

that are installed incorrectly, and 

installing an axis in the cable cut switch 

guard. EASA AD 2020–0084 also 

specifies that an affected part can be 

installed on any helicopter, provided it 

has been marked. 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. 

Costs of Compliance 

The FAA estimates that this AD 

affects 30 helicopters of U.S. registry. 

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 

0.50 work-hour × $85 per hour = $42.50 .................................................................................... $0 $42.50 $1,275 

The FAA estimates the following 

costs to do any necessary on-condition 

actions that would be required based on 

the results of any required actions. The 

FAA has no way of determining the 

number of helicopters that might need 

these on-condition actions: 

ESTIMATED COSTS OF ON-CONDITION ACTIONS

Labor cost Parts cost Cost per 

product 

2 work-hours × $85 per hour = $170 ...................................................................................................................... $56 $226 

According to the manufacturer, some 

or all of the costs of this AD may be 

covered under warranty, thereby 

reducing the cost impact on affected 

operators. The FAA does not control 

warranty coverage for affected operators. 

As a result, the FAA has included all 

known costs in the cost estimate. 

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 


jbell on DSKJLSW7X2PROD with RULES
Federal Register / Vol. 86, No. 103 / Tuesday, June 1, 2021 / Rules and Regulations 29189 

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. 

List of Subjects in 14 CFR Part 39
