SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2023–04–06, 

Amendment 39–22353 (88 FR 13665, 

March 6, 2023) (AD 2023–04–06), and 

AD 2024–04–07, Amendment 39–22686 

(89 FR 19234, March 18, 2024). AD 

2023–04–06 and AD 2024–04–07 

applied to Airbus SAS Model A318– 

111, –112, –121, and –122 airplanes; 

Model A319–111, –112, –113, –114, 

–115, –131, –132, –133, –151N, –153N, 

and –171N airplanes; Model A320–211, 

–212, –214, –216, –231, –232, –233, 

–251N, –252N, –253N, –271N, –272N, 

and –273N airplanes; and Model A321– 

111, –112, –131, –211, –212, –213, –231, 

–232, –251N, –252N, –253N, –271N, 

–272N, –251NX, –252NX, –253NX, 

–271NX, and –272NX airplanes. AD 

2023–04–06 and AD 2024–04–07 

required revising the existing 

maintenance or inspection program, as 

applicable, to incorporate additional 

new or more restrictive airworthiness 

limitations. The FAA issued AD 2023– 

04–06 and AD 2024–04–07 to address a 

safety-significant latent failure. 

The NPRM published in the Federal 

Register on June 18, 2024 (89 FR 51471). 

The NPRM was prompted by AD 2024– 

0030, dated January 31, 2024, issued by 

EASA, which is the Technical Agent for 

the Member States of the European 

Union (EASA AD 2024–0030) (also 

referred to as the MCAI). The MCAI 

states that new or more restrictive 

airworthiness limitations have been 

developed. 

In the NPRM, the FAA proposed to 

require revising the existing 

maintenance or inspection program, as 

applicable, to incorporate additional 

new or more restrictive airworthiness 

limitations, as specified in EASA AD 

2024–0030. The FAA is issuing this AD 

to address a safety significant latent 

failure (that is not annunciated), which, 

in combination with one or more other 

specific failures or events, could result 

in a hazardous or catastrophic failure 

condition. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2024–1685. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received comments from the 

Air Line Pilots Association, 

International (ALPA) who supported the 

NPRM without change. 

Additional Changes Made To This AD 

The proposed AD did not retain the 

terminating action specified in 

paragraph (j) of AD 2024–04–07. The 

FAA has added that terminating action 

to paragraph (j) of this AD and 

redesignated subsequent paragraphs of 

this AD accordingly.

Federal Register / Vol. 89, No. 204 / Tuesday, October 22, 2024 / Rules and Regulations 84275 

Conclusion 

This product has been approved by 

the aviation authority of another 

country and is 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 the MCAI referenced above. The FAA 

reviewed the relevant data, considered 

the comment 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 this product. Except for 

minor editorial changes, and any other 

changes described previously, 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 2024–0030 specifies 

procedures for new or more restrictive 

airworthiness limitations for airplane 

structures and safe life limits. 

This AD also requires EASA AD 

2023–0138, dated July 13, 2023, which 

the Director of the Federal Register 

approved for incorporation by reference 

as of April 22, 2024 (89 FR 19234, 

March 18, 2024). 

This AD also requires EASA AD 

2022–0091, dated May 20, 2022, which 

the Director of the Federal Register 

approved for incorporation by reference 

as of April 10, 2023 (88 FR 13665, 

March 6, 2023). 

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 1,898 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this AD: 

The FAA estimates the total cost per 

operator for the retained actions from 

AD 2023–04–06 and AD 2024–04–07 to 

be $7,650 (90 work hours × $85 per 

work hour) per AD. 

The FAA has determined that revising 

the existing maintenance or inspection 

program takes an average of 90 work 

hours per operator, although the agency 

recognizes that this number may vary 

from operator to operator. Since 

operators incorporate maintenance or 

inspection program changes for their 

affected fleet(s), the FAA has 

determined that a per-operator estimate 

is more accurate than a per-airplane 

estimate. 

The FAA estimates the total cost per 

operator for the new proposed actions to 

be $7,650 (90 work hours × $85 per 

work hour). 

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.

Airworthiness Directives; DAHER 

(Type Certificate Previously Held by 

SOCATA) Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2016–08– 

08 for all SOCATA (type certificate now 

held by DAHER) Model MS 880B, MS 

885, MS 892A–150, MS 892E–150, MS 

893A, MS 893E, MS 894A, MS 894E, 

Rallye 100S, Rallye 150ST, Rallye 150T, 

Rallye 235C, and Rallye 235E airplanes. 

AD 2016–08–08 required doing 

repetitive detailed visual inspections of 

the intersection between the axle radius 

and the nose landing gear (NLG) fork 

area for chafing; doing repetitive dye 

penetrant inspections on the NLG wheel 

axle for cracks, distortion, and nicks or 

wear; doing corrective actions if 

necessary; and replacing the NLG wheel 

axle attachment screws with new 

screws. This AD is prompted by the 

introduction of a new inspection 

method and a new design for the 

affected NLG wheel axle that provides 

terminating action for the repetitive 

inspections, as specified in updated 

service information published by the 

manufacturer. This AD requires 

preparing, inspecting, replacing, 

reconditioning the NLG wheel axle, and 

prohibiting affected parts. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

DATES: This AD is effective November 

26, 2024. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of November 26, 2024.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2016–08–08, 

Amendment 39–18484 (81 FR 21711, 

April 13, 2016) (AD 2016–08–08). AD 

2016–08–08 applied to SOCATA (type 

certificate now held by DAHER) Model 

MS 880B, MS 885, MS 892A–150, MS 

892E–150, MS 893A, MS 893E, MS 

894A, MS 894E, Rallye 100S, Rallye 

150ST, Rallye 150T, Rallye 235C, and 

Rallye 235E airplanes. 

AD 2016–08–08 was prompted by 

MCAI originated by European Union 

Aviation Safety Agency (EASA), which 

is the Technical Agent for the Member 

States of the European Union. EASA 

issued AD 2015–0203, dated October 7, 

2015 (EASA AD 2015–0203) to correct 

an unsafe condition identified as fatigue 

failure of the NLG wheel axle. EASA AD 

2015–0203 was prompted by an NLG 

wheel axle failure that occurred in 

service. The investigation revealed that 

this failure was due to fatigue caused by 

premature wear. EASA AD 2015–0203 

required retaining the requirements of 

Direction Ge ́ne ́rale de l’Aviation Civile 

(DGAC) France AD 91–163(A)R2, dated 

March 30, 1994, which was superseded, 

but required those actions to be 

accomplished within reduced intervals. 

AD 2016–08–08 required doing 

repetitive detailed visual inspections of 

the intersection between the axle radius 

and the NLG fork area for chafing; doing 

repetitive dye penetrant inspections on 

the NLG wheel axle for cracks, 

distortion, and nicks or wear; corrective 

actions if necessary; and replacing the 

NLG wheel axle attachment screws with 

new screws. The FAA issued AD 2016– 

08–08 to address chafing and cracking 

of the NLG wheel axle, which could 

lead to failure of the NLG with 

consequent damage to the airplane and/ 

or injury to occupants. 

Since the FAA issued AD 2016–08– 

08, EASA superseded EASA AD 2015– 

0203 and issued EASA AD 2023–0080, 

dated April 17, 2023 (EASA AD 2023– 

0080) (also referred to as the MCAI) to 

correct an unsafe condition for all 

DAHER AEROSPACE Model MS 880 B, 

MS 880 B–D, MS 881, MS 883, MS 884, 

MS 885, MS 886, MS 887, MS 890 A, 

MS 890 B, MS 892 A.150, MS 892 

B.150, MS 892 E.150, MS 892 E–D.150, 

MS 893 A, MS 893 B, MS 893 E, MS 893 

E–D, MS 894 A, MS 894 E, RALLYE 100 

S, RALLYE 100 S–D, RALLYE 100 ST, 

RALLYE 100 ST–D, RALLYE 110 ST, 

RALLYE 150 ST, RALLYE 150 ST–D, 

RALLYE 150 T, RALLYE 150 T–D, 

RALLYE 150 SV, RALLYE 150 SVS, 

RALLYE 180 T, RALLYE 180 TS, 

RALLYE 180 T–D, RALLYE 235 A, 

RALLYE 235 F, RALLYE 235 E, and 

RALLYE 235 E–D airplanes. 

The MCAI states that it retains the 

requirements of EASA AD 2015–0203 

but introduces a new inspection method 

and a new design of the NLG wheel axle 

as a terminating action for the repetitive 

detailed inspections. You may examine 

the MCAI in the AD docket at 

regulations.gov under Docket No. FAA– 

2024–1480.
