standard design approval, or 

manufacturing license under 10 CFR 

part 52 that propose to use materials 

allowed under Section III–5. Section III– 

5 specifies the mechanical properties 

and allowable stresses to be used for 

design of components in high 

temperature reactors. Because Section 

III–5 states that it does not provide 

methods to evaluate deterioration that 

may occur in service as a result of 

corrosion, mass transfer phenomena, 

radiation effects, or other material 

instabilities, this ISG identifies 

information that the NRC staff should 

consider as part of its review of a nonlight-water reactor application to review 

applicable design requirements, 

including qualification and monitoring 

programs for safety-significant 

structures, systems, and components. 

III. Additional Information 

Draft DANU–ISG–2023–01 ‘‘Material 

Compatibility for Non-Light Water 

Reactors’’ was published in the Federal 

Register for public comment on March 

7, 2023, (88 FR 14186) with a 60-day 

comment period. The NRC received 

fifteen public comments from private 

citizens and industry organizations. The 

NRC staff’s evaluation and resolution of 

the public comments are documented in 

Appendix A to the ISG in ADAMS 

under Accession No. ML23188A178. 

IV. Congressional Review Act 

DANU–ISG–2023–01 ‘‘Material 

Compatibility for Non-Light Water 

Reactors’’ 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.

Airworthiness Directives; He ́licopte`res 

Guimbal Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2023–24– 

51 which applied to all He ́licopte`res 

Guimbal Model Cabri G2 helicopters. 

AD 2023–24–51 was prompted by 

reports of a crack in the pilot cyclic 

stick base and required repetitively 

inspecting certain part-numbered pilot 

and co-pilot cyclic stick bases and, 

depending on the results, corrective 

action. AD 2023–24–51 also prohibited 

installing those pilot and co-pilot cyclic 

stick bases unless certain requirements 

were met. Since the FAA issued AD 

2023–24–51, more cracks in the cyclic 

stick bases have been reported, 

including a crack in a cyclic stick base 

that had accumulated only 700 hours 

time-in-service (TIS). This AD requires 

the same actions as AD 2023–24–51 but 

reduces the compliance time for 

performing the initial inspection. These 

actions are specified in a European 

Union Aviation Safety Agency (EASA) 

AD, which is incorporated by reference. 

The FAA previously sent this AD as an 

emergency AD to all known U.S. owners 

and operators of these helicopters. The 

FAA is issuing this AD to address the 

unsafe condition on these products. 

DATES: This AD is effective February 21, 

2024. Emergency AD 2024–01–52, 

issued on January 9, 2024, which 

contained the requirements of this 

amendment, was effective with actual 

notice. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of February 21, 2024. 

The FAA must receive comments on 

this AD by March 22, 2024. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following

Background 

On November 21, 2023, the FAA 

issued Emergency AD 2023–24–51 to 

address an unsafe condition on all 

He ́licopte`res Guimbal Model Cabri G2 

helicopters. Emergency AD 2023–24–51 

published in the Federal Register as a 

Final rule; request for comments on 

December 13, 2023 (Amendment 39– 

22627, 88 FR 86260) (AD 2023–24–51). 

AD 2023–24–51 was issued after EASA, 

which is the Technical Agent for the 

Member States of the European Union, 

issued EASA Emergency AD 2023– 

0204–E, dated November 20, 2023 

(EASA AD 2023–0204–E) and was 

prompted by reports of a crack in the 

pilot cyclic stick base. EASA AD 2023– 

0204–E stated that investigation 

determined that the root cause of the 

cracks was fatigue, primarily related to 

induced loads on the cyclic stick during 

pre-flight (free play) checks. 

Accordingly, EASA AD 2023–0204–E 

required repetitively inspecting certain 

part-numbered pilot and co-pilot cyclic 

stick bases and, depending on the 

results, corrective action. EASA AD 

2023–0204–E also prohibited installing 

those pilot and co-pilot cyclic stick 

bases unless its requirements were met. 

AD 2023–24–51 required repetitively 

inspecting certain part-numbered pilot 

and co-pilot cyclic stick bases for a 

crack and, depending on the results, 

removing the cracked cyclic stick base 

from service and replacing it with a 

serviceable cyclic stick base in 

accordance with a method approved by 

the FAA, EASA, or He ́licopte`res 

Guimbal EASA Design Organization 

Approval (DOA). AD 2023–24–51 also 

prohibited installing an affected pilot or 

co-pilot cyclic stick base unless it was 

new (zero total hours TIS) or it passed 

its required inspection. The FAA issued 

AD 2023–24–51 to detect a cracked pilot 

or co-pilot cyclic stick base. The unsafe 

condition, if not addressed, could result 

in failure of the pilot or co-pilot cyclic 

stick base and subsequent loss of control 

of the helicopter. 

Actions Since AD 2023–24–51 Was 

Issued 

Since the FAA issued AD 2023–24– 

51, more cracks in the cyclic stick base 

have been reported, including a crack in 

a cyclic stick base that had accumulated 

only 700 hours TIS; therefore, EASA 

issued EASA Emergency AD 2024– 

0007–E, dated January 8, 2024 (EASA 

AD 2024–0007–E), to supersede EASA 

AD 2023–0204–E. EASA AD 2024– 

0007–E states that a revision of the 

service bulletin related to the unsafe 

condition lowers the threshold for the 

initial inspection of the pilot and copilot cyclic stick bases. Accordingly, 

EASA AD 2024–0007–E continues to 

require repetitively inspecting certain 

part-numbered pilot and co-pilot cyclic 

stick bases and, depending on the 

results, corrective action, but requires 

the initial inspection at a lower 

threshold. EASA AD 2024–0007–E also 

prohibits installing those pilot and copilot cyclic stick bases unless its 

requirements are met. You may examine 

EASA AD 2024–0007–E in the AD 

docket at regulations.gov under Docket 

No. FAA–2024–0037. 

Subsequently, on January 9, 2024, the 

FAA issued Emergency AD 2024–01–52 

(Emergency AD 2024–01–52) and sent it 

to all known U.S. owners and operators 

of these helicopters. Emergency AD 

2024–01–52 supersedes AD 2023–24–51 

and continues to require inspecting 

certain part-numbered pilot and co-pilot 

cyclic stick bases and, depending on the 

results, corrective action, but reduces 

the threshold for the initial inspection 

from 1,500 hours TIS accumulated on 

the affected part to 205 hours TIS. 

Emergency AD 2024–01–52 also 

continues to prohibit installing those 

pilot and co-pilot cyclic stick bases 

unless certain requirements are met. 

FAA’s Determination 

These products have been approved 

by the aviation authority of another 

country and are approved for operation 

in the United States. Pursuant to the 

FAA’s bilateral agreement with this 

State of Design Authority, it has notified 

the FAA of the unsafe condition 

described in its emergency AD and 

service information described below. 

The FAA is issuing this AD after 

determining that the unsafe condition 

described previously is likely to exist or 

develop on other products of the same 

type designs. 

Related Service Information Under 1 

CFR Part 51 

The FAA reviewed EASA AD 2024– 

0007–E, which requires repetitively 

inspecting pilot cyclic stick base part 

number (P/N) G41–42–801 and co-pilot 

cyclic stick base P/Ns G41–43–801 and 

G41–43–802 for a crack. EASA AD 

2024–0007–E reduces the initial 

inspection from 1,500 FH [flight hours] 

accumulated on the affected part to 205 

FH [flight hours] and retains the 60–FH 

[flight hour] repetitive inspections. 

Depending on the inspection results, 

EASA AD 2024–0007–E requires 

contacting HG [He ́licopte`res Guimbal] 

for approved instructions to replace a 

cracked cyclic stick base and 

accomplishing those instructions 

accordingly. EASA AD 2024–0007–E 

also allows removing the dual control 

(co-pilot cyclic stick) instead of 

replacing a cracked co-pilot cyclic stick 

base. Finally, EASA AD 2024–0007–E 

prohibits installing a specified pilot or 

co-pilot cyclic stick base unless it is a 

new (never installed before) part or, 

before installation, has passed its 

required inspection. 

The FAA also reviewed Guimbal 

Mandatory Service Bulletin SB 23–006, 

Revision D, dated January 5, 2024 (SB 

23–006D), which specifies performing 

an initial 205-hour TIS inspection 

(reduced from a prior initial inspection 

of 1,500 hours TIS) followed by 

repetitive inspections of both the pilot 

and copilot cyclic bases for cracks. SB 

23–006D specifies doing the inspection 

using a flashlight and in case of doubt, 

performing a dye-penetrant inspection. 

If there is a crack on the pilot’s side, SB 

23–006D specifies grounding the 

helicopter and contacting HG 

[He ́licopte`res Guimbal]; if there is a 

crack on the copilot’s side, SB 23–006D 

specifies removing the dual controls and 

contacting HG.

This service information 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. 

AD Requirements 

This AD requires accomplishing the 

actions specified in EASA AD 2024– 

0007–E, described previously, as 

incorporated by reference, except for 

any differences identified as exceptions 

in the regulatory text of this AD and 

except as discussed under ‘‘Differences 

Between this AD and the EASA 

Emergency AD.’’ 

Explanation of Required Compliance 

Information 

In the FAA’s ongoing efforts to 

improve the efficiency of the AD 

process, the FAA developed a process to 

use some civil aviation authority (CAA) 

ADs as the primary source of 

information for compliance with 

requirements for corresponding FAA 

ADs. The FAA has been coordinating 

this process with manufacturers and 

CAAs. As a result, EASA AD 2024– 

0007–E is incorporated by reference in 

this FAA final rule. This AD, therefore, 

requires compliance with EASA AD 

2024–0007–E in its entirety through that 

incorporation, except for any differences 

identified as exceptions in the 

regulatory text of this AD. Using 

common terms that are the same as the 

heading of a particular section in EASA 

AD 2024–0007–E does not mean that 

operators need comply only with that 

section. For example, where the AD 

requirement refers to ‘‘all required 

actions and compliance times,’’ 

compliance with this AD requirement is 

not limited to the section titled 

‘‘Required Action(s) and Compliance 

Time(s)’’ in EASA AD 2024–0007–E. 

Service information referenced in EASA 

AD 2024–0007–E for compliance will be 

available at regulations.gov under 

Docket No. FAA–2024–0037 after this 

final rule is published. 

Differences Between This AD and the 

EASA Emergency AD 

The service information referenced in 

EASA AD 2024–0007–E specifies 

performing a dye-penetrant inspection 

in case of a doubt regarding if there is 

a crack, whereas this AD does not 

require that action. If there is cracked 

pilot or co-pilot cyclic stick base, EASA 

AD 2024–0007–E requires contacting 

HG [He ́licopte`res Guimbal] for approved 

instructions to replace it with a 

serviceable part and accomplishing 

those instructions accordingly and the 

service information referenced in EASA 

AD 2024–0007–E specifies contacting 

HG [He ́licopte`res Guimbal] or removing 

the dual controls and contacting HG 

[He ́licopte`res Guimbal], whereas this 

AD requires removing the cracked cyclic 

stick base from service and replacing it 

with a serviceable cyclic stick base in 

accordance with a method approved by 

the FAA, EASA, or He ́licopte`res 

Guimbal EASA DOA. Where Table 1 in 

EASA AD 2024–0007–E states, ‘‘During 

next maintenance check without 

exceeding 205 FH,’’ this AD requires 

replacing that text with, ‘‘Within 205 

hours time-in-service.’’ 

Interim Action 

The FAA considers this AD to be an 

interim action. If final action is later 

identified, the FAA might consider 

further rulemaking then. 

Justification for Immediate Adoption 

and Determination of the Effective Date 

Section 553(b)(3)(B) of the 

Administrative Procedure Act (APA) (5 

U.S.C. 551 et seq.) authorizes agencies 

to dispense with notice and comment 

procedures for rules when the agency, 

for ‘‘good cause,’’ finds that those 

procedures are ‘‘impracticable, 

unnecessary, or contrary to the public 

interest.’’ Under this section, an agency, 

upon finding good cause, may issue a 

final rule without providing notice and 

seeking comment prior to issuance. 

Further, section 553(d) of the APA 

authorizes agencies to make rules 

effective in less than thirty days, upon 

a finding of good cause. 

An unsafe condition exists that 

required the immediate adoption of 

Emergency AD 2024–01–52, issued on 

January 9, 2024, to all known U.S. 

owners and operators of these 

helicopters. The FAA found that the risk 

to the flying public justified waiving 

notice and comment prior to adoption of 

this rule because the affected 

component is part of an assembly that 

is critical to the control of a helicopter. 

As the FAA also has no information 

pertaining to the quantity of cracked 

components that may currently exist in 

the U.S. fleet or how quickly the 

condition may propagate to failure, the 

actions required by this AD must be 

accomplished before further flight for 

certain helicopters. These conditions 

still exist, therefore, notice and 

opportunity for prior public comment 

are impracticable and contrary to the 

public interest pursuant to 5 U.S.C. 

553(b)(3)(B). 

In addition, the FAA finds that good 

cause exists pursuant to 5 U.S.C. 553(d) 

for making this amendment effective in 

less than 30 days, for the same reasons 

the FAA found good cause to forego 

notice and comment. 

Regulatory Flexibility Act 

The requirements of the Regulatory 

Flexibility Act (RFA) do not apply when 

an agency finds good cause pursuant to 

5 U.S.C. 553 to adopt a rule without 

prior notice and comment. Because the 

FAA has determined that it has good 

cause to adopt this rule without prior 

notice and comment, RFA analysis is 

not required. 

Costs of Compliance 

The FAA estimates that this AD 

affects 50 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. 

Inspecting a pilot or co-pilot cyclic 

stick base takes a minimal amount of 

time for a nominal cost. If required, 

replacing a pilot cyclic stick base takes 

about 3 work-hours and parts cost about 

$1,585 for an estimated cost of $1,840 

per helicopter; and replacing a co-pilot 

cyclic stick base takes about 1 workhour and parts cost about $711 for an 

estimated cost of $796 per helicopter. 

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, 

and 


ddrumheller on DSK120RN23PROD with RULES1

(a) Effective Date 

The FAA issued Emergency Airworthiness 

Directive (AD) 2024–01–52 on January 9, 

2024, directly to affected owners and 

operators. As a result of such actual notice, 

that emergency AD was effective for those 

owners and operators on the date it was 

provided. This AD contains the same 

requirements as that emergency AD and, for 

those who did not receive actual notice, is 

effective on February 21, 2024. 

(b) Affected ADs 

This AD replaces AD 2023–24–51, 

Amendment 39–22627 (88 FR 86260, 

December 13, 2023). 

(c) Applicability 

This AD applies to He ́licopte`res Guimbal 

Model Cabri G2 helicopters, certificated in 

any category. 

(d) Subject 

Joint Aircraft System Component (JASC) 

Code: 6710, Main Rotor Control. 

(e) Unsafe Condition 

This AD was prompted by reports of a 

crack in the pilot cyclic stick base. The FAA 

is issuing this AD to detect a cracked pilot 

or co-pilot cyclic stick base. The unsafe 

condition, if not addressed, could result in 

failure of the pilot or co-pilot cyclic stick 

base and subsequent loss of control of the 

helicopter. 

(f) Compliance 

Comply with this AD within the 

compliance times specified, unless already 

done. 

(g) Requirements 

Except as specified in paragraph (h) of this
