Airworthiness Directives; Airbus 

Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for certain 

Airbus Helicopters Model SA330J 

helicopters. This AD was prompted by 

a review of Model EC225LP helicopter 

data that revealed potential tightening 

torque loss of the attachment screws of 

the upper deck fittings of the three main 

gearbox (MGB) suspension bars. Due to 

design similarities, the MGB right-hand 

(RH) rear fittings and MGB RH rear 

fitting attachment screws on Model 

SA330J helicopters could also be 

affected. Additional analysis confirmed 

that the service life limit (life limit) 

(SLL) for these affected MGB RH rear 

fittings needs to be reduced for 

helicopters on which these affected 

parts were operated concurrently with 

metallic main rotor blades installed. 

This AD requires determining the 

damage value and SLL of each affected 

MGB RH rear fitting, replacing each 

affected MGB RH rear fitting with a new 

part, and replacing the MGB RH rear 

fitting attachment screws, 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 May 9, 2022. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of May 9, 2022.

SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2021– 

0152R1, dated July 20, 2021 (EASA AD 

2021–0152R1), to correct an unsafe 

condition for Airbus Helicopters 

(formerly Eurocopter, Eurocopter 

France, Aerospatiale, Sud Aviation) 

Model SA 330 J helicopters, all serial 

numbers, which were modified in 

service in accordance with the 

instructions of Eurocopter France 

Service Bulletin (SB) No. 01.20 (part of 

which is the in-service retrofit 

Modification (Mod) 07 40043), except 

those on which each affected part (as 

defined in EASA AD 2021–0152R1) was 

replaced with a new part (not 

previously installed) during 


khammond on DSKJM1Z7X2PROD with RULES
Federal Register / Vol. 87, No. 64 / Monday, April 4, 2022 / Rules and Regulations 19377 

embodiment of Eurocopter France SB 

No. 01.20 in service. 

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 SA330J helicopters. The NPRM 

published in the Federal Register on 

January 13, 2022 (87 FR 2085). The 

NPRM was prompted by a review of 

Model EC225LP helicopter in-service 

data that revealed potential tightening 

torque loss of the attachment screws of 

the upper deck fittings of the three MGB 

suspension bars. The FAA issued AD 

2020–06–12, Amendment 39–19881 (85 

FR 19077, April 6, 2020) to address the 

unsafe condition on Model EC225LP 

helicopters). Due to design similarities, 

the MGB RH rear fittings and MGB RH 

rear fitting attachment screws on Model 

SA330J helicopters could also be 

affected. Additional analysis confirmed 

that the SLL for these affected MGB RH 

rear fittings needs to be reduced for 

helicopters on which these affected 

parts were operated concurrently with 

metallic main rotor blades (pre-Airbus 

Helicopters Modification 07 40043) 

installed. Airbus Helicopters 

Modification 07 40043 introduced the 

installation of composite main rotor 

blades. The NPRM proposed to require 

determining the damage value and SLL 

of each affected MGB RH rear fitting, 

replacing each affected MGB RH rear 

fitting with a new part, and replacing 

the MGB RH rear fitting attachment 

screws, as specified in EASA AD 2021– 

0152R1. 

The FAA is issuing this AD to address 

tightening torque loss of the attachment 

screws of the upper deck fittings of the 

three MGB suspension bars. The unsafe 

condition, if not addressed, could result 

in structural failure of the MGB RH rear 

fittings and MGB RH rear fitting 

attachment screws, resulting in 

detachment of the MGB suspension bars 

and consequent loss of control of the 

helicopter. See EASA AD 2021–0152R1 

for additional background information. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the NPRM or on the determination of 

the costs. 

Conclusion 

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 reviewed 

the relevant data and determined that 

air safety requires adopting this AD as 

proposed. Accordingly, the FAA is 

issuing this AD to address the unsafe 

condition on these helicopters. Except 

for minor editorial changes, this AD is 

adopted as proposed in the NPRM. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2021–0152R1 requires 

determining the damage value of each 

affected MGB RH rear fitting by 

calculating the damage caused during 

the time each affected part was operated 

concurrently with metallic main rotor 

blades installed on the helicopter, 

calculating the SLL for each affected 

MGB RH rear fitting, and eventually 

replacing each affected MGB RH rear 

fitting and the MGB RH rear fitting 

attachment screws with new parts. 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. 

Costs of Compliance 

The FAA estimates that this AD 

affects 15 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.

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.

FAA–2021–1176; Project Identifier 

MCAI–2021–00755–R. 

(a) Effective Date 

This airworthiness directive (AD) is 

effective May 9, 2022. 

(b) Affected ADs 

None. 

(c) Applicability 

This AD applies to Airbus Helicopters 

Model SA330J helicopters, certificated in any 

category, as identified in European Union 

Aviation Safety Agency (EASA) AD 2021– 

0152R1, dated July 20, 2021 (EASA AD 

2021–0152R1). 

(d) Subject 

Joint Aircraft Service Component (JASC) 

Code: 6300, Main Rotor Drive System. 

(e) Unsafe Condition 

This AD was prompted by a review of 

Airbus Helicopters Model EC225LP 

helicopter data that revealed potential 

tightening torque loss of the attachment 

screws of the upper deck fittings of the three 

main gearbox (MGB) suspension bars. Due to 

design similarities, the MGB right-hand (RH) 

rear fittings and MGB RH rear fitting 

attachment screws on Model SA330J 

helicopters could also be affected. Additional 

analysis confirmed that the service life limit 

(life limit) (SLL) for the affected MGB RH rear 

fittings needs to be reduced for helicopters 

on which these affected parts were operated 

concurrently with metallic main rotor blades 

installed. The FAA is issuing this AD to 

address tightening torque loss of the 

attachment screws of the upper deck fittings 

of the three MGB suspension bars. The 

unsafe condition, if not addressed, could 

result in structural failure of the MGB RH 

rear fittings and MGB RH rear fitting 

attachment screws, resulting in detachment 

of the MGB suspension bars and consequent 

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 

AD: Comply with all required actions and 

compliance times specified in, and in 

accordance with, EASA AD 2021–0152R1. 

(h) Exceptions to EASA AD 2021–0152R1 

(1) Where EASA AD 2021–0152R1 requires 

compliance in terms of flight hours, this AD 

requires using hours time-in-service. 

(2) Where EASA AD 2021–0152R1 refers to 

July 9, 2021 (the effective date of EASA AD 

2021–0152R1, dated June 25, 2021), this AD 

requires using the effective date of this AD. 

(3) Where the service information 

referenced in EASA AD 2021–0152R1 

specifies discarding parts, this AD requires 

removing those parts from service. 

(4) Although the service information 

referenced in EASA AD 2021–0152R1 

specifies that ‘‘The work must be performed 

on the helicopter by the operator.’’ this AD 

does not require that the operator perform the 

work. 

(5) This AD does not mandate compliance 

with the ‘‘Remarks’’ section of EASA AD 

2021–0152R1. 

(6) The preliminary steps specified in 

paragraph 3.B.1. of the service information 

referenced in EASA AD 2021–0152R1 are not 

required for compliance with this AD. 

(7) Although the service information 

referenced in EASA AD 2021–0152R1 

specifies contacting Airbus Helicopters if the 

time since new (TSN) is unknown at the 

retrofit date, this AD requires determining 

the damage value and the SLL of each 

affected part but does not require contacting 

Airbus Helicopters if the TSN is unknown at 

the retrofit date. 

(i) No Reporting Requirement 

Although the service information 

referenced in EASA AD 2021–0152R1 

specifies to submit certain information to the 

manufacturer, this AD does not include that 

requirement. 

(j) Alternative Methods of Compliance 

(AMOCs) 

(1) The Manager, International Validation 

Branch, FAA, has the authority to approve 

AMOCs for this AD, if requested using the
