AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all 

Airbus Helicopters Deutschland GmbH 

(AHD) Model MBB–BK117 A–1, MBB– 

BK117 A–3, MBB–BK117 A–4, MBB– 

BK117 B–1, MBB–BK117 B–2, MBB– 

BK117 C–1, MBB–BK117 C–2, and 

MBB–BK117 D–2 helicopters. This AD 

was prompted by the FAA’s 

determination that aging of the 

elastomeric material of certain tension 

torsion straps (TT-Straps), during the 

period since manufacturing date up to 

first flight on a helicopter, may affect its 

structural characteristics. This AD 

requires the replacement of certain TTStraps, implementation of storage life 

limits for TT-Straps, a prohibition on 

installing certain TT-Straps, and 

conditions for installation of certain 

other TT-Straps, 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 8, 2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of July 8, 2022.

SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021–0122, 

dated May 6, 2021 (EASA AD 2021– 

0122), to correct an unsafe condition for 

all Airbus Helicopters Deutschland 

GmbH (AHD) (formerly Eurocopter 

Deutschland GmbH, Eurocopter 

Hubschrauber GmbH, MesserschmittBo ̈lkow-Blohm GmbH; Airbus 

Helicopters Inc., formerly American 

Eurocopter LLC) Model MBB–BK117 A– 

1, MBB–BK117 A–3, MBB–BK117 A–4, 

MBB–BK117 B–1, MBB–BK117 B–2, 


khammond on DSKJM1Z7X2PROD with RULES
Federal Register / Vol. 87, No. 107 / Friday, June 3, 2022 / Rules and Regulations 33631 

MBB–BK117 C–1, MBB–BK117 C–2, 

and 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 all Airbus Helicopters 

Deutschland GmbH (AHD) Model MBB– 

BK117 A–1, MBB–BK117 A–3, MBB– 

BK117 A–4, MBB–BK117 B–1, MBB– 

BK117 B–2, MBB–BK117 C–1, MBB– 

BK117 C–2, and MBB–BK117 D–2 

helicopters. The NPRM published in the 

Federal Register on March 28, 2022 (87 

FR 17201). The NPRM was prompted by 

the FAA’s determination that aging of 

the elastomeric material of certain TTStraps, during the period since 

manufacturing date up to first flight on 

a helicopter, may affect its structural 

characteristics. The NPRM proposed to 

require the replacement of certain TTStraps, implementation of storage life 

limits for TT-Straps, a prohibition on 

installing certain TT-Straps, and 

conditions for installation of certain 

other TT-Straps, as specified in EASA 

AD 2021–0122. 

The FAA is issuing this AD to address 

aging of the elastomeric material of 

certain TT-Straps. The unsafe condition, 

if not addressed, could result in 

premature failure of a TT-Strap, 

possibly resulting in loss of control of 

the helicopter. See EASA AD 2021–0122 

for additional background information. 

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 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 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. Except 

for minor editorial changes, this AD is 

adopted as proposed in the NPRM. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2021–0122 requires the 

replacement of certain TT-straps, 

implementation of storage life limits for 

TT-Straps since cure date, a prohibition 

on installing certain TT-Straps, and 

provides conditions for installation of 

certain other TT-Straps. 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 213 helicopters of U.S. Registry. 

Labor rates are estimated at $85 per 

work-hour. Based on these numbers, the 

FAA estimates the following costs to 

comply with this AD. 

ESTIMATED COSTS

product

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.
