Airworthiness Directives; Airbus 

Helicopters 

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 

Airbus Helicopters (Airbus) Model 

AS350B, AS350B1, AS350B2, AS350B3, 

AS350BA, AS350D, AS355E, AS355F, 

AS355F1, AS355F2, AS355N, AS355NP, 

EC130B4, and EC130T2 helicopters. 

This proposed AD was prompted by a 

manufacturer assessment that 

determined additional actions are 

necessary to improve particle detection 

for main gearboxes (MGBs) with certain 

planet gear bearings installed. This 

proposed AD would require repetitively 

inspecting the MGB bevel wheel for the 

presence of particles, repetitively 

inspecting the MGB magnetic plug for 

particles, and prohibit installing an 

affected MGB unless certain 

requirements are met. These actions are 

specified in a European Union Aviation 

Safety Agency (EASA) AD, which is 

proposed for incorporation by reference. 

The FAA is proposing this AD to 

address the unsafe condition on these 

products. 

DATES: The FAA must receive comments 

on this NPRM by December 20, 2024. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods:

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2023–0044, 

dated February 28, 2023, (EASA AD 

2023–0044) to correct an unsafe 

condition on Airbus Model AS 350 B, 

AS 350 D, AS 350 B1, AS 350 B2, AS 

350 BA, AS 350 BB, AS 350 B3, EC 130 

B4, EC 130 T2, AS 355 E, AS 355 F, AS 

355 F1, AS 355 F2, AS355 N, and 

AS355 NP helicopters. EASA advises 

that after a fleet design review for 

detection of particles in the MGB, it was 

determined that additional maintenance 

actions are necessary to improve 

detection of particles in the MGB. The 

FAA is proposing this AD to detect and 

correct the presence of particles in the 

MGB, which if not addressed, could 

result in reduced or loss of control of 

the helicopter. 

You may examine EASA AD 2023– 

0044 in the AD docket at regulations.gov 

under Docket No. FAA–2024–2419. 

Material Incorporated by Reference 

Under 1 CFR Part 51 

EASA AD 2023–0044 requires 

repetitive borescope visual inspections 

of the bevel wheel of the affected MGB 

for particles, collecting and analyzing 

any found particles, and depending on 

the results, further actions, 

accomplishing corrective action in 

accordance with the ASB defined 

within, or contacting AH [Airbus 

Helicopters] for further corrective 

action. EASA AD 2023–0044 also 

requires accomplishing a borescope 

visual inspection of the bevel wheel of 

the affected MGB for particles following 

the detection of any particles at the 

MGB magnetic plug during 

accomplishment of certain maintenance 

tasks and depending on the results, 

taking corrective action. Lastly, EASA 

AD 2023–0044 prohibits installing an 

affected MGB on any helicopter unless 

it is a serviceable part as defined within 

and certain requirements are met. 

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. 

Other Related Material 

The FAA reviewed Airbus Alert 

Service Bulletin No. AS350–05.01.04, 

No. AS355–05.00.87, and No. EC130– 

05A040, each Revision 0, and each 

dated January 25, 2023. This material 

specifies procedures for borescope 

inspecting the MGB bevel wheel for 

particles and, depending on the results, 

replacing a damaged epicyclic module 

or bevel reduction module with an 

airworthy part, and collecting the 

particles using a vacuum pump and 

analyzing the particles. 

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 these 

same type designs. 

Proposed AD Requirements in This 

NPRM 

This proposed AD would require 

accomplishing the actions specified in 

EASA AD 2023–0044, described 

previously, as incorporated by 

reference, except for any differences 

identified as exceptions in the 


ddrumheller on DSK120RN23PROD with PROPOSALS1
Federal Register / Vol. 89, No. 214 / Tuesday, November 5, 2024 / Proposed Rules 87823 

regulatory text of this proposed AD and 

except as discussed under ‘‘Differences 

Between this Proposed AD and EASA 

AD 2023–0044.’’ 

This proposed AD would require 

certain actions within compliance times 

specified in certain material referenced 

for compliance in EASA AD 2023–0044, 

particularly for corrective actions for 

scales, flakes, or splinters. Depending 

on the measurements of the scales, 

flakes, or splinters, corrective actions 

include close monitoring, metallurgical 

analysis within 50 hours time-inserivce, or removing each affected 

module and additional actions when 

certain criteria are exceeded. 

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, the FAA proposes to 

incorporate EASA AD 2023–0044 by 

reference in the FAA final rule. This 

proposed AD would, therefore, require 

compliance with EASA AD 2023–0044 

in its entirety through that 

incorporation, except for any differences 

identified as exceptions in the 

regulatory text of this proposed AD. 

Using common terms that are the same 

as the heading of a particular section in 

EASA AD 2023–0044 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 2023–0044. 

Material referenced in EASA AD 2023– 

0044 for compliance will be available at 

www.regulations.gov by searching for 

and locating Docket No. FAA–2024– 

2419 after the FAA final rule is 

published. 

Differences Between This Proposed AD 

and EASA AD 2023–0044 

EASA AD 2023–0044 applies to 

Model AS350BB helicopters, whereas 

this proposed AD would not because 

that model is not FAA-type certificated. 

Where Note 1 in the material 

referenced in EASA AD 2023–0044 

specifies the option of 1 mechanical 

technician and 1 crew member, for this 

proposed AD, the pilot is only permitted 

to turn the tail rotor (b) because the 

other actions specified in the note must 

be accomplished by persons authorized 

under 14 CFR 43.3. Therefore, for the 

purposes of this proposed AD, the 

owner/operator (pilot) may turn the tail 

rotor (b) and must enter compliance 

with the applicable paragraph of this 

proposed AD in the helicopter 

maintenance records in accordance with 

14 CFR 43.9(a) and 91.417(a)(2)(v). The 

pilot may perform this action because it 

only involves turning the tail rotor (b). 

This action can be performed equally 

well by a pilot or a mechanic. This 

action is an exception to the FAA’s 

standard maintenance regulations. 

This proposed AD would not require 

complying with paragraph (2) of EASA 

AD 2023–0044. Instead, this proposed 

AD would require repetitively 

inspecting the MGB magnetic plug for 

particles and, if there is any particle, 

accomplishing a borescope visual 

inspection, as specified in paragraphs 

(h)(6)(i) and (ii) of this proposed AD. 

Where the material referenced in 

EASA AD 2023–0044 specifies 

contacting Airbus Helicopters for a 

certain action, this proposed AD would 

require accomplishing action in 

accordance with a method approved the 

FAA, EASA, or Airbus Helicopters’ 

EASA Design Organization Approval. 

Costs of Compliance 

The FAA estimates that this AD, if 

adopted as proposed, would affect 522 

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. 

A repetitive visual borescope 

inspection of the MGB bevel wheel 

would take 1 work-hour for an 

estimated cost of $85 per helicopter and 

$44,370 for the U.S. fleet, per inspection 

cycle. 

If necessary, collecting and 

performing a metallurgical analysis of 

the detected particles would take 6 

work-hours for an estimated cost of 

$510 per helicopter, per analysis. 

Repetitively inspecting the magnetic 

plugs of the MGB would take 1 workhour for an estimated cost of $85 per 

helicopter and $44,370 for the U.S. fleet, 

per inspection cycle. 

If required, close monitoring would 

take 2 work-hours for an estimated cost 

of $170 per helicopter, per close 

monitoring cycle. 

Accomplishing a visual borescope 

inspection of the MGB bevel wheel as a 

result of an MGB magnetic plug 

inspection would take 1 work-hour for 

an estimated cost of $85 per helicopter. 

If necessary, replacing an epicyclic 

module would take 56 work-hours and 

parts would cost $50,524 (overhauled) 

for an estimated cost of $55,284 per 

module. 

If necessary, replacing a bevel 

reduction module would take 56 workhours and parts would cost $18,500 

(overhaled) for an estimated cost of 

$23,260 per module. 

Certain corrective action could vary 

significantly from helicopter to 

helicopter. The FAA has no data to 

determine the costs to accomplish the 

corrective action. 

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) 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.

‘‘serviceable MGB’’ as ‘‘An affected MGB 

which has accumulated less than 330 flight 

hours (FH) since new (first installation on a 

helicopter), or since an overhaul, or since an 

inspection in accordance with the 

instructions of the ASB;’’ for this AD, replace 

that text with ‘‘An affected MGB which has 

accumulated less than 330 total hours timein-service since new (zero total hours timein-service), since last overhaul if an overhaul 

has been accomplished, or since last 

inspection and any specified corrective 

action in accordance with the instructions of 

the ASB if an inspection and any specified 

corrective action by following the 

instructions of the ASB have been 

accomplished.’’ 

(2) Where EASA AD 2023–0044 requires 

compliance in terms of flight hours, this AD 

requires using hours time-in-service (TIS). 

(3) Where EASA AD 2023–0044 refers to its 

effective date, this AD requires using the 

effective date of this AD. 

(4) Where Note 1 in the material referenced 

in paragraph (1) of EASA AD 2023–0044 

specifies the option of 1 mechanical 

technician and 1 crew member, for this AD, 

the pilot is only permitted to turn the tail 

rotor (b). The owner/operator (pilot) holding

specified in Note 1 in the material referenced 

in paragraph (1) of EASA AD 2023–0044 

must be accomplished by persons authorized 

under 14 CFR 43.3. 

(5) Where Note 2 in the material referenced 

in paragraph (1) of EASA AD 2023–0044 

specifies contacting Airbus Helicopters for 

further instructions if the bottom of the 

radius (a6) of the bevel wheel (a3) or head 

screws (a4) (see Figure 2) are not clearly 

visible, this AD requires, before further flight, 

accomplishing action in accordance with a 

method approved by the FAA, EASA, or 

Airbus Helicopters’ EASA Design 

Organization Approval (DOA). If approved by 

the DOA, the approval must include the 

DOA-authorized signature. 

(6) Instead of complying with paragraph (2) 

of EASA AD 2023–0044, comply with the

‘‘accomplishing corrective actions in 

accordance with a method approved by the 

FAA, EASA, or Airbus Helicopters’ EASA 

DOA. If approved by the DOA, the approval 

must include the DOA-authorized signature.’’ 

(12) Where paragraph (7) of EASA AD 

2023–0044 states ‘‘since new (first 

installation a helicopter), or since an 

overhaul, or since an inspection in 

accordance with the instructions of the ASB, 

as applicable, and, thereafter, as required by 

this AD;’’ for this AD, replace that text with 

‘‘since new (zero total hours time-in-service), 

or since last overhaul if an overhaul has been 

accomplished, or since last inspection and 

any specified corrective action in accordance 

with the instructions of the ASB if an 

inspection and any specified corrective 

action by following the instructions of the 

ASB have been accomplished, and thereafter 

as required by this AD.’’.’’ 

(13) This AD does not adopt the ‘‘Remarks’’ 

section of EASA AD 2023–0044. 

(i) No Reporting Requirement 

Although the material referenced in EASA 

AD 2023–0044 specifies to submit certain 

information to the manufacturer, this AD 

does not require that action.

SUPPLEMENTARY INFORMATION: 

Background 

On October 23, 2024, BIS published 

the proposed rule ‘‘Export 

Administration Regulations: Revisions 

to Space-Related Export Controls, 

including Addition of License 

Exception Commercial Space Activities 

(CSA)’’ (89 FR 84784), which proposed 

changes to controls for spacecraft and 

related items under the EAR that would 

conform to proposed changes to the 

International Traffic in Arms 

Regulations related to U.S. Munitions 

List Categories IV and XV. This rule also 

proposed the addition of a new license 

exception for certain Commercial Space 

Activities (CSA). These proposed rules 

are intended to better enable a globally 

competitive U.S. space industrial base 

while continuing to protect U.S. 

national security and foreign policy 

interests.
