SUPPLEMENTARY INFORMATION: 

Background 

EASA, which is the Technical Agent 

for the Member States of the European 

Union, has issued EASA AD 2023–0105, 

dated May 23, 2023 (EASA AD 2023– 

0105), to correct an unsafe condition on 

Leonardo S.p.A. Model A109C, A109E, 

A109K2, A109LUH, A109S, and 

AW109SP helicopters. 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply to all Leonardo S.p.a. Model 

A109C, A109E, A109K2, A109S, and 

AW109SP helicopters. The NPRM 

published in the Federal Register on 

December 11, 2023 (88 FR 85856). The 


lotter on DSK11XQN23PROD with RULES1
Federal Register / Vol. 89, No. 179 / Monday, September 16, 2024 / Rules and Regulations 75473 

1Leonardo Helicopters Alert Service Bulletin 

(ASB) No. 109–158, ASB No. 109EP–180, ASB No. 

109K–076, ASB No. 109S–115, and ASB No. 

109SP–154, each dated March 21, 2023, contain 

updated maintenance procedures (referenced as 

‘‘Annex A’’ or ‘‘Annex B’’ in the ASBs, as 

applicable) for assembling the tail rotor housing and 

slider assembly. The updated maintenance 

procedures are MM Paragraph 64–30–3 Revision 5, 

MM Paragraph 64–31–6 Revision 16, MM Paragraph 

64–30–5 Revision 5, MM Paragraph 64–31–6 Rev. 

6, and AMP DM 0B–A–64–31–06–00A–710A–B 

Issue 13, as applicable. The identified ASBs are 

referenced in EASA AD 2023–0105 for compliance 

and will be available at regulations.gov under 

Docket No. FAA–2023–2238 after this FAA final 

rule is published. 

NPRM was prompted by reports of loose 

tail rotor duplex bearing locking nuts. 

Investigations identified incorrect 

accomplishment of the assembly and 

continued maintenance instructions of 

the tail rotor duplex bearing housing 

and slider group as the most likely root 

cause of that loosening. Accordingly, 

the NPRM proposed to require 

disassembling certain tail rotor duplex 

bearing housings and pitch change 

slider assemblies and reassembling 

them in accordance with updated 

procedures. The NPRM also proposed to 

prohibit installing certain tail rotor 

duplex bearing housings and pitch 

change slider assemblies. These actions 

are specified in EASA AD 2023–0105. 

The FAA is issuing this AD to detect 

and address the incorrect assembly of 

the tail rotor duplex bearing. This 

unsafe condition, if not addressed, 

could lead to failure of the tail rotor 

function, possibly resulting in loss of 

control of the helicopter. See EASA AD 

2023–0105 for additional background 

information. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from 

one commenter, Air Methods. The 

following presents the comments 

received on the NPRM and the FAA’s 

response to each comment. 

Comments Regarding Compliance With 

Updated Maintenance Procedures 

Air Methods commented that, upon 

review of the ASB [alert service 

bulletin] and the existing MM 

[maintenance manual], changes to the 

MM appear to be relatively minor 

between the existing MM procedures 

and the updated maintenance 

procedures (defined in EASA AD 2023– 

0105 as ‘‘the updated procedure’’ and 

that are included in the alert service 

bulletins 1 that are referenced for 

compliance). Air Methods also 

requested the FAA to advise of the 

reasoning behind the proposed AD 

requirement when the maintenance 

procedures should get updated to 

accurately reflect the new work steps 

and this area has a 180-day recurrent 

inspection. 

The FAA infers that Air Methods is 

requesting justification of the proposed 

requirement in the NPRM to replace an 

affected part, as defined in EASA AD 

2023–0105, with a serviceable part, as 

defined in EASA AD 2023–0105, which 

may be done by following certain 

maintenance procedures to disassemble 

the affected part and updated 

maintenance procedures to reassemble 

the affected part, instead of allowing for 

accomplishment of anticipated updated 

maintenance procedures to address the 

unsafe condition without an AD. The 

FAA cannot require a manufacturer to 

revise its maintenance publications and, 

operators are subject to the specific 

manufacturer’s maintenance procedures 

at time of delivery, which may vary. 

Therefore, to mandate specific 

procedures when an unsafe condition 

has been determined, the FAA must 

issue an AD to address and correct that 

unsafe condition. Lastly, compliance 

times in AD actions commonly specify 

multiple compliance time units to 

capture varying usage of the fleet and 

various factors related to the unsafe 

condition. The compliance time 

proposed by the NPRM to accomplish 

the replacement is within 100 hours 

time-in-service or 6 months, whichever 

occurs first. The purpose of the ‘‘within 

100 hours time-in-service’’ compliance 

time unit is to capture high usage 

helicopters, which have an increased 

likeliness of occurrence of a failure, that 

a 180-day compliance time alone would 

not capture to an acceptable level of 

safety. 

Comments Regarding Compliance With 

Future Revisions of the Updated 

Maintenance Procedures 

Air Methods stated that there are 

three levels of documents to comply 

with to accomplish the proposed AD; 

EASA AD 2023–0105, the ASB [alert 

service bulletins] (that are referred to as 

‘‘the ASB’’ and referenced in EASA AD 

2023–0105 for compliance), and MM 

[maintenance manual] (particularly, 

maintenance procedures, that are 

referenced in the alert service bulletins 

for compliance and are normally 

available in maintenance publications). 

Air Methods also stated that the 

proposed AD does not address future 

revisions of the updated maintenance 

procedures identified in EASA AD 

2023–0105 (defined in EASA AD 2023– 

0105 as ‘‘the updated procedure’’) and 

the alert service bulletins. 

The NPRM proposed to require 

accomplishing the required actions and 

compliance times specified in EASA AD 

2023–0105 with certain exceptions. 

Through that incorporation, the NPRM 

proposed to allow using future revisions 

of the maintenance procedures because 

EASA AD 2023–0105 defines ‘‘the 

updated procedure’’ by identifying 

certain revisions of the maintenance 

procedures for the applicable model 

helicopters and explicitly states ‘‘or 

later revisions;’’ and, the NPRM did not 

propose an exception to prohibit using 

later revisions of the updated 

maintenance procedures. The NPRM 

did not propose compliance with part II 

of the alert service bulletins. 

Air Methods asked if the FAA intends 

to require an AD logbook signoff each 

time this area is disassembled/ 

reassembled after the initial task 

compliance. Air Methods also asked if 

the signoff with the ‘‘the updated 

procedure’’ as identified in EASA AD 

2023–0105, or later, is sufficient for 

future maintenance as it is impossible to 

forecast unplanned maintenance and 

the current version of the maintenance 

procedures would be used for this 

maintenance. 

The requirements proposed in the 

NPRM do not require an AD logbook 

signoff each time the tail rotor duplex 

bearing housing or pitch change slider 

assembly are disassembled and 

reassembled. The NPRM proposed to 

require a one-time replacement, and 

compliance must be entered into the 

helicopter maintenance records in 

accordance with 14 CFR 43.9(a) and 

91.417(a)(2)(v) for that one-time 

replacement. Thereafter, the NPRM 

proposed to prohibit installing any tail 

rotor duplex bearing housing part 

number (P/N) 109–0130–94–XXX and 

any pitch change slider assembly P/N 

109–0130–91–XXX (with ‘‘XXX’’ 

representing any numerical sequence) 

that has been disassembled and 

(re)assembled in service using 

maintenance procedures issued prior to 

the updated procedure, as defined in 

EASA AD 2023–0105. There is no 

logbook entry for part installation 

prohibitions because the identified parts 

must not be installed on any 

helicopters. 

Additional Changes Since the NPRM 

Was Issued 

Since the FAA issued the NPRM, two 

errors in EASA AD 2023–0105 have 

been identified. EASA AD 2023–0105 

inadvertently omits ‘‘MM Paragraph 64– 

31–6 Rev. 6’’ (for certain serialnumbered Model A109K2 helicopters) 

in its definition of ‘‘the updated 

procedure’’ and inadvertently identifies 

the updated procedures as ‘‘(as 

referenced in Annex A of the ASB).’’ 


lotter on DSK11XQN23PROD with RULES1
75474 Federal Register / Vol. 89, No. 179 / Monday, September 16, 2024 / Rules and Regulations 

The FAA is correcting the omission by 

adding an exception to revise the 

definition of ‘‘the updated procedure’’ 

and is correcting the misidentification 

by adding an exception to replace that 

text with ‘‘(as referenced in Annex A or 

B of the ASB, as applicable).’’ These 

corrections are relieving as they reduce 

the population of ‘‘affected parts’’ as 

defined in EASA AD 2023–0105. 

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, considered the 

comments received, 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 the changes described previously 

and minor editorial changes, this AD is 

adopted as proposed in the NPRM. 

None of the changes will increase the 

economic burden on any operator. 

Material Incorporated by Reference 

Under 1 CFR Part 51 

EASA AD 2023–0105 requires 

replacing certain parts through the 

disassembly and reassembly of the tail 

rotor duplex bearing and the pitch 

change slider assembly. EASA AD 

2023–0105 also prohibits installing 

certain parts on any helicopter. 

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. 

Differences Between This AD and the 

EASA 

EASA AD 2023–0105 applies to 

Model A109LUH helicopters, whereas 

this AD does not because that model is 

not FAA type-certificated. 

Costs of Compliance 

The FAA estimates that this AD 

affects 160 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. 

Disassembly and reassembly of the 

tail rotor housing and slider assembly 

will take approximately 8 work-hours 

for an estimated cost of $680 per 

helicopter and $108,800 for the U.S. 

fleet. 

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.

DEPARTMENT OF TRANSPORTATION 

Federal Aviation Administration 

14 CFR Part 97 

[Docket No. 31564; Amdt. No. 4129] 

Standard Instrument Approach 

Procedures, and Takeoff Minimums 

and Obstacle Departure Procedures; 

Miscellaneous Amendments 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: This rule establishes, amends, 

suspends, or removes Standard 

Instrument Approach Procedures 

(SIAPS) and associated Takeoff 

Minimums and Obstacle Departure 

procedures (ODPs) for operations at 

certain airports. These regulatory 

actions are needed because of the 

adoption of new or revised criteria, or 

because of changes occurring in the 

National Airspace System, such as the 

commissioning of new navigational 

facilities, adding new obstacles, or 

changing air traffic requirements. These 

changes are designed to provide safe 

and efficient use of the navigable 

airspace and to promote safe flight 

operations under instrument flight rules 

at the affected airports. 

DATES: This rule is effective September 

16, 2024. The compliance date for each 

SIAP, associated Takeoff Minimums, 

and ODP is specified in the amendatory 

provisions. 

The incorporation by reference of 

certain publications listed in the 

regulations is approved by the Director 

of the Federal Register as of September 

16, 2024.

amendment is as follows:

SUPPLEMENTARY INFORMATION: This rule 

amends 14 CFR part 97 by establishing, 

amending, suspending, or removes 

SIAPS, Takeoff Minimums and/or 

ODPS. The complete regulatory 

description of each SIAP and its 

associated Takeoff Minimums or ODP 

for an identified airport is listed on FAA 

form documents which are incorporated 

by reference in this amendment under 5 

U.S.C. 552(a), 1 CFR part 51, and 14 

CFR 97.20. The applicable FAA Forms 

are 8260–3, 8260–4, 8260–5, 8260–15A, 

8260–15B, when required by an entry 

on 8260–15A, and 8260–15C. 

The large number of SIAPs, Takeoff 

Minimums and ODPs, their complex 

nature, and the need for a special format 

make publication in the Federal 

Register expensive and impractical. 

Further, pilots do not use the regulatory 

text of the SIAPs, Takeoff Minimums or 

ODPs, but instead refer to their graphic 

depiction on charts printed by 

publishers or aeronautical materials. 

Thus, the advantages of incorporation 

by reference are realized and 

publication of the complete description 

of each SIAP, Takeoff Minimums and 

ODP listed on FAA form documents is 

unnecessary. This amendment provides 

the affected CFR sections and specifies 

the types of SIAPS, Takeoff Minimums 

and ODPs with their applicable effective 

dates. This amendment also identifies
