VIII. Congressional Review Act 

This notification of interpretation is a 

rule as defined in the Congressional 

Review Act (5 U.S.C. 801–808). 

However, the Office of Management and 

Budget has not found it to be a major 

rule as defined in the Congressional 

Review Act. 

IX. Conclusion 

The requirement of § 34.41(a) is met if 

the additional qualified individual is in 

sufficiently close proximity to the 

operation and sufficiently aware of the 

ongoing activities to be able to provide 

assistance or take charge when 

necessary and to prevent unauthorized 

entry. In addition, the compatibility 

category for § 34.41(a) is changed to 

Category C. This notification of 

interpretation addresses the issues 

identified in PRM–34–6 regarding the 

two-person rule. Therefore, the NRC has 

preliminarily concluded that 

rulemaking is no longer necessary and 

is proposing discontinuing the 

rulemaking activity initiated in response 

to PRM–34–6. 

In addition, the NRC has concluded 

that the training requirements for the 

second qualified individual in § 34.43(c) 

are sufficient to ensure safe radiographic 

operations. The NRC’s review of 

operational experience since 1997 

shows that the NRC’s training 

requirements for the second qualified 

individual, either a radiographer’s 

assistant or radiographer, are adequate 

to protect public health and safety. 

Therefore, the NRC proposes denying 

PRM–34–6. 

Dated at Rockville, Maryland, this 26th day 

of May 2021.

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Airbus Helicopters Model EC130B4 and 

EC130T2 helicopters. This AD was

geometrical non-conformities of the tail 

rotor blades (TRBs); all cracks initiated 

in the drain hole area at the blade root 

section. This AD requires cleaning 

affected parts, visual and dye penetrant 

inspections for cracks of affected parts, 

a dimensional inspection to verify 

conformity of affected parts, and 

corrective actions if necessary, 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 6, 2021. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of July 6, 2021.

SUPPLEMENTARY INFORMATION: 

Background 

The EASA, which is the Technical 

Agent for the Member States of the 

European Union, has issued EASA AD 

2020–0187, dated August 21, 2020 

(EASA AD 2020–0187) (also referred to 

as the Mandatory Continuing 

Airworthiness Information, or the 

MCAI), to correct an unsafe condition 

for all Airbus Helicopters Model 

EC130B4 and EC130T2 helicopters. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to certain Airbus Helicopters 

Model EC130B4 and EC130T2 

helicopters. The NPRM published in the 

Federal Register on March 15, 2021 (86 


jbell on DSKJLSW7X2PROD with RULES
Federal Register / Vol. 86, No. 103 / Tuesday, June 1, 2021 / Rules and Regulations 29177 

FR 14290). The NPRM was prompted by 

a report of cracks and geometrical nonconformities of the TRBs; all cracks 

initiated in the drain hole area at the 

blade root section. The NPRM proposed 

to require cleaning affected parts, visual 

and dye penetrant inspections for cracks 

of affected parts, a dimensional 

inspection to verify conformity of 

affected parts, and corrective actions if 

necessary, as specified in an EASA AD. 

The FAA is issuing this AD to address 

geometrical non-conformities of the 

TRBs, which could lead to crack 

initiation and consequent blade failure, 

and possible loss of control of the 

helicopter. 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. 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 2020–0187 specifies 

procedures for cleaning affected parts, 

visual and dye penetrant inspections for 

cracks of affected parts (the cleaning 

and visual and dye penetrant 

inspections are one-time or repetitive, 

depending on the accumulated hours 

time in service on the TRB), a one-time 

dimensional inspection to verify 

conformity of affected parts, and 

corrective actions if necessary. 

Corrective actions include replacement 

of the affected part with a serviceable 

part, and additional repetitive cleaning 

and inspections until replacement of the 

affected part with a serviceable 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. 

Interim Action 

The FAA considers this AD interim 

action. If final action is later identified, 

the FAA might consider further 

rulemaking then. 

Costs of Compliance 

The FAA estimates that this AD 

affects 264 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 

7 work-hours × $85 per hour = $595 .......................................................................................... $0 $595 $157,080 

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 

4 work-hours × $85 per hour = $340 ...................................................................................................................... $4,641 $4,981 

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.

assembly on the intermediate rib in the 

center fuel tank was mislocated, 

resulting in an offset between the fitting 

assembly and the refuel/defuel tube 

assembly. This AD requires 

modification of the fuel pipe bracket 

assembly, including all related 

investigative actions and corrective 

actions, if necessary; and performing an 

operational test of the refuel and defuel 

system. The FAA is issuing this AD to 

address the unsafe condition on these 

products. 

DATES: This AD is effective July 6, 2021. 

The Director of the Federal Register
