khammond on DSKJM1Z7X2PROD with PROPOSALS
Federal Register / Vol. 86, No. 110 / Thursday, June 10, 2021 / Proposed Rules 30823 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2018–0087, 

dated April 18, 2018 (EASA AD 2018– 

0087), to correct an unsafe condition for 

Leonardo S.p.A. Helicopters (formerly 

Finmeccanica S.p.A., AgustaWestland 

S.p.A.) Model AW189 helicopters. 

EASA advises of revisions resulting in 

Leonardo AW189 Maintenance Manual, 

Document 89–A–AMPI–00–P, Chapter 

IV, Airworthiness Limitations, Issue 13 

(89–A–AMPI–00–P ALS Issue 13), 

which includes new and/or more 

restrictive airworthiness limitations and 

maintenance tasks since its original 

issuance. Failure to accomplish those 

airworthiness limitations and 

maintenance tasks could result in an 

unsafe condition. 

Accordingly, EASA AD 2018–0087 

requires accomplishing the actions 

specified in 89–A–AMPI–00–P ALS 

Issue 13 and revising the Aircraft 

Maintenance Program (AMP) with the 

actions specified in 89–A–AMPI–00–P 

ALS Issue 13. 

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 

proposing 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 the same 

type design. 

Related Service Information 

The FAA reviewed AW189 Air 

Vehicle Maintenance Planning 

Information, 89–B–AMPI–00–P, Chapter 

4, Issue 6, dated July 17, 2018 (89–B– 

AMPI–00–P ALS Issue 6). 89–B–AMPI– 

00–P ALS Issue 6 specifies various 

airworthiness limitations information 

including retirement lives, mandatory 

inspections, and certification 

maintenance requirements. 89–B– 

AMPI–00–P ALS Issue 6 is equivalent to 

89–A–AMPI–00–P ALS Issue 13. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require 

determining the total hours time-inservice (TIS) and total number of 

landings of tail gearbox fitting part 

number (P/N) 4F5350A04152. If the 

total hours TIS and total number of 

landings cannot be determined, this 

proposed AD would require removing 

the part from service. This proposed AD 

would establish a life limit for tail 

gearbox fitting P/N 4F5350A04152 and 

require removing the part from service 

according to the new life limit. 

Differences Between This Proposed AD 

and the EASA AD 

EASA AD 2018–0087 applies to 

Model AW189 helicopters, whereas this 

proposed AD would apply to that model 

helicopter with tail gearbox fitting P/N 

4F5350A04152 installed instead. EASA 

AD 2018–0087 requires accomplishing 

the actions specified in 89–A–AMPI– 

00–P ALS Issue 13 and revising the 

AMP with the actions specified in 89– 

A–AMPI–00–P ALS Issue 13, whereas 

this proposed AD would require 

establishing a life limit for tail gearbox 

fitting P/N 4F5350A04152 and removing 

that part from service accordingly 

instead. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 4 

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 proposed AD. 

Replacing a tail gearbox fitting would 

take about 48 work-hours and parts 

would cost about $30,000 for an 

estimated cost of $34,080 per helicopter 

and $136,320 for the U.S. fleet, per 

replacement cycle. 

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 

proposed AD would not have federalism 

implications under Executive Order 

13132. This proposed 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, I certify 

this proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Would not affect intrastate 

aviation in Alaska, and 

(3) Would 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 

Air transportation, Aircraft, Aviation 

safety, Incorporation by reference, 

Safety. 

The Proposed Amendment

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for 

certain Bell Textron Inc. (type certificate 

previously held by Bell Helicopter 

Textron Inc.) (Bell) Model 205B 

helicopters. This proposed AD was 

prompted by a notification of certain 

parts needing a life limit. This proposed 

AD would require determining the total 

hours time-in-service (TIS) of certain 

part numbered main rotor grip 

assemblies (grip assemblies), 

establishing a life limit for certain partnumbered grip assemblies, removing 

from service any grip assembly that has 

reached or exceeded its retirement life, 

creating a component history card, and 

removing any grip assembly from 

service before reaching its retirement 

life. This proposed AD would also 

prohibit installing certain grip 

assemblies unless the life limit was 

established in accordance with this 

proposed AD. The FAA is proposing 

this AD to address the unsafe condition 

on these products.
