III. Specific Considerations 

This report documents completion of 

the staff’s initial review of QA criteria 

and 10 CFR 50.59 requirements for AMT 

applications at U.S. nuclear power 

plants. This report does not represent a 

complete and final analysis of all 

aspects of QA criteria and 10 CFR 50.59 

requirements and guidance that might 

be applicable to the use of AMT 

components at U.S. nuclear power 

plants. This report does not create new 

regulatory requirements or establish 

new regulatory positions with respect to 

the use or manufacture of AMT 

components for nuclear power plants. 

The scope of this report is limited to the 

review of existing requirements and 

guidance to address AMT components 

and the consideration of potential 

regulatory and technical challenges. 

This report may be subject to future 

revision, as additional insights and 

operating experience for use of AMT 

components are gained. 

The NRC is requesting general 

comments on this document to be open 

and transparent in processes involving 

the installation of AMT-fabricated 

components. 

IV. Public Meeting 

The NRC plans to hold a public 

meeting during the public comment 

period for this action. A public meeting 

is planned for December 2020, via 

webinar. The public meeting will 

provide forums for the NRC staff to 

discuss issues and questions with 

members of the public. The NRC does 

not intend to provide any responses to 

comments submitted during the public 

meeting. The public meeting will be 

noticed on the NRC’s public meeting

Discussion 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD No. 2019– 

0199, dated August 16, 2019, to correct 

an unsafe condition for Airbus 

Helicopters Deutschland GmbH (AHD), 

formerly Eurocopter Deutschland 

GmbH, Eurocopter Espan ̃ a S.A., Model 

EC135 P1, EC135 P2, EC135 P2+, EC135 

P3, EC135 T1, EC135 T2, EC135 T2+, 

EC135 T3, EC635 P2+, EC635 P3, EC635 

T1, EC635 T2+, and EC635 T3 

helicopters. EASA advises of a report of 

a broken Ti-bolt. Subsequent 

investigation revealed that an improper 

heat treatment process was 

accomplished on a batch of Ti-bolts, 

which can lead to hydrogen 

embrittlement. The investigation also 

identified the critical location where 

these Ti-bolts are installed on 

helicopters. According to EASA, this 

condition, if not detected and corrected, 

could lead to failure of an affected Tibolt installed in a critical location, 

possibly resulting in reduced control of 

the helicopter. Accordingly, the EASA 

AD requires a one-time inspection of Tibolt part number (P/N) L535M2001203 

marked with manufacturer monogram 

‘‘D’’ or with an illegible manufacturer 

monogram installed on the forward tail 

rotor (T/R) drive shaft and, depending 

on the inspection results, replacing the 

Ti-bolt. The EASA AD also prohibits the 

(re)installation of these Ti-bolts. 

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 an unsafe condition is 

likely to exist or develop on other 

helicopters of these same type designs. 

Related Service Information 

The FAA reviewed Airbus Helicopters 

Alert Service Bulletin (ASB) No. EC135– 

00A–001, Revision 1, dated September 

2, 2019, for Airbus Helicopters 

Deutschland GmbH Model EC135 T1, 

T2, T2+, T3, P1, P2, P2+, P3, 635 T1, 

635 T2+, 635 T3, 635 P2+, and 635 P3 

helicopters, and Airbus Helicopters ASB 

No. EC135H–00A–001, Revision 1, 

dated September 2, 2019, for Airbus 

Helicopters Deutschland GmbH Model 

EC135, T3H, P3H, 635 T3H, and 635 

P3H helicopters. This service 

information specifies inspecting the 

forward T/R drive shaft, distance plate 

of the 5B–0.50–2.50P–XN–1 antenna, 

main rotor controls, FWD connection of 

ball bearing control, and AFT 

connection of ball bearing control and 

yaw actuator for the installation of Tibolt P/N L535M2001203, EN3308– 

040020F, L221M1040201, EN3740– 

060020F, and EN3308–060020F, marked 

with manufacturer monogram ‘‘D’’ or an 

illegible manufacturer monogram. If a 

specified Ti-bolt is installed, the service 

information specifies replacing the Tibolt and discarding the removed Ti-bolt. 

Proposed AD Requirements 

This proposed AD would require 

removing any Ti-bolt P/N 

L535M2001203 marked with 

manufacturer monogram ‘‘D’’ or with an 

illegible manufacturer monogram 

installed on the forward T/R drive shaft 

from service. This proposed AD would 

also prohibit installing an affected Tibolt on the forward T/R drive shaft of 

any helicopter. 

Differences Between This Proposed AD 

and the EASA AD 

The EASA AD applies to Model 

EC135 P1, EC135 P2, EC135 P2+, EC135 

P3, EC135 T1, EC135 T2, EC135 T2+, 

EC135 T3, EC635 P2+, EC635 P3, EC635 

T1, EC635 T2+, and EC635 T3 

helicopters and requires inspecting Tibolt P/N L535M2001203 marked with 

manufacturer monogram ‘‘D’’ or with an 

illegible manufacturer monogram 

installed on the forward T/R drive shaft. 

This proposed AD applies to Model 

EC135P1, EC135P2, EC135P2+, 

EC135P3, EC135T1, EC135T2, 

EC135T2+, and EC135T3 helicopters 

with a Ti-bolt P/N L535M2001203 

marked with manufacturer monogram 

‘‘D’’ or with an illegible manufacturer 

monogram installed on the forward T/R 

drive shaft instead. This proposed AD 

does not apply to Model EC635 P2+, 

EC635 P3, EC635 T1, EC635 T2+, or 

EC635 T3 helicopters because these 

models are not FAA type-certificated. 

The EASA AD requires discarding the 

affected Ti-bolts, whereas this proposed 

AD would require removing the affected 

Ti-bolts from service instead. 

Costs of Compliance 

The FAA estimates that this proposed 

AD affects 326 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 proposed AD. 

Replacing a Ti-bolt would take about 

four work-hours and parts would cost 

about $82 for an estimated cost of $422 

per Ti-bolt. 

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 above, I 

certify this proposed regulation: 

(1) Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866, 

(2) Will not affect intrastate aviation 

in Alaska, and 


TKELLEY on DSKBCP9HB2PROD with PROPOSALS
76492 Federal Register / Vol. 85, No. 230 / Monday, November 30, 2020 / Proposed Rules 

(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.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to adopt a 

new airworthiness directive (AD) for all 

Safran Helicopter Engines, S.A. (Safran) 

Arriel 2D and Arriel 2E model 

turboshaft engines. This proposed AD 

was prompted by the manufacturer 

revising the maintenance and overhaul 

manuals to introduce new or more 

restrictive airworthiness limitations and 

maintenance tasks. This proposed AD 

would require the replacement of 

certain critical parts before reaching 

their published in-service life limits, 

performing scheduled maintenance 

tasks before reaching their published 

periodicity, and performing 

unscheduled maintenance tasks when 

the engine meets certain conditions. As 

a terminating action, this proposed AD 

would require operators to revise the 

airworthiness limitation section (ALS) 

of their existing approved aircraft 

maintenance program (AMP) by 

incorporating the revised airworthiness 

limitations and maintenance tasks. The 

FAA is proposing this AD to address the 

unsafe condition on these products. 

DATES: The FAA must receive comments 

on this proposed AD by January 14, 

2021. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:
