Airworthiness Directives; Dassault 

Aviation Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2020–23– 

10, which applied to certain Dassault 

Aviation Model FAN JET FALCON and 

FAN JET FALCON SERIES C, D, E, F, 

and G airplanes. AD 2020–23–10 

required revising the existing 

maintenance or inspection program, as 

applicable, to incorporate new or more 

restrictive airworthiness limitations. 

This AD was prompted by a 

determination that new or more 

restrictive airworthiness limitations are 

necessary. This AD continues to require 

the actions in AD 2020–23–10 and 

requires revising the existing 

maintenance or inspection program, as 

applicable, to incorporate additional 

new or more restrictive airworthiness 

limitations, 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 December 

26, 2023. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of December 26, 2023.

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2020–23–10, 

Amendment 39–21326 (85 FR 73404, 

November 18, 2020) (AD 2020–23–10). 

AD 2020–23–10 applied to certain 

Dassault Aviation Model FAN JET 

FALCON and FAN JET FALCON 

SERIES C, D, E, F, and G airplanes. AD 

2020–23–10 required revising the 

existing maintenance or inspection 

program, as applicable, to incorporate 

new or more restrictive airworthiness 

limitations. The FAA issued AD 2020– 

23–10 to address, among other things, 

fatigue cracking and damage in 

principle structural elements; such 

fatigue cracking and damage could 

result in reduced structural integrity of 

the airplane. 

The NPRM published in the Federal 

Register on August 14, 2023 (88 FR 

54935). The NPRM was prompted by 

AD 2023–0060, dated March 16, 2023, 

issued by EASA, which is the Technical 

Agent for the Member States of the 

European Union (EASA AD 2023–0060) 

(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 

continue to require the actions in AD 

2020–23–10 and 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 2023–0060. The FAA is 

issuing this AD to address the unsafe 

condition on these products. 

You may examine the MCAI in the 

AD docket at regulations.gov under 

Docket No. FAA–2023–1651. 

Discussion of Final Airworthiness 

Directive 

Comments 

The FAA received no comments on 

the NPRM or on the determination of 

the cost to the public. 

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 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, this AD is adopted as proposed 

in the NPRM. None of the changes will 

increase the economic burden on any 

operator. 

Related Service Information Under 1 

CFR Part 51 

EASA AD 2023–0060 specifies new or 

more restrictive airworthiness 

limitations for airplane structures and 

safe life limits. 

This AD also requires EASA AD 

2019–0141, dated June 17, 2019, which 

the Director of the Federal Register 

approved for incorporation by reference 

as of December 23, 2020 (85 FR 73404, 

November 18, 2020). 

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 168 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 2020–23–10 to be $7,650 (90 workhours × $85 per work-hour). 

The FAA has determined that revising 

the existing maintenance or inspection 

program takes an average of 90 workVerDate Sep<11>2014 16:15 Nov 17, 2023 Jkt 262001 PO 00000 Frm 00018 Fmt 4700 Sfmt 4700 E:\FR\FM\20NOR1.SGM 20NOR1

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 actions to be 

$7,650 (90 work-hours × $85 per workhour). 

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; Pratt & 

Whitney Division Engines 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2018–02– 

10, which applied to certain Pratt & 

Whitney Division (PW) Model PW4074, 

PW4074D, PW4077, PW4077D, 

PW4084D, PW4090, and PW4090–3 

engines. AD 2018–02–10 required 

performing repetitive fluorescent 

penetrant inspections (FPIs) to detect 

cracks in the outer diffuser case (ODC), 

removal of any ODC that fails 

inspection, and updating the mandatory 

inspections in the Airworthiness 

Limitations Section (ALS) of the 

Instructions for Continued 

Airworthiness (ICA). Since the FAA 

issued AD 2018–02–10, PW developed a 

modification to reduce the susceptibility 

of ODC cracking. This AD retains the 

ALS update requirement from AD 2018– 

02–10, requires replacing certain ODC 

part numbers with parts eligible for 

installation, expands the applicability to 

all ODC part numbers, and adjusts the 

compliance threshold of the FPIs of the 

ODC. The FAA is issuing this AD to 

address the unsafe condition on these 

products. 

DATES: This AD is effective December 

26, 2023. 

The Director of the Federal Register

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to supersede AD 2018–02–10, 

Amendment 39–19163 (FR 83 2896, 

January 22, 2018), (‘‘AD 2018–02–10’’). 

AD 2018–02–10 applied to PW Model 

PW4074, PW4074D, PW4077, 

PW4077D, PW4084D, PW4090, and 

PW4090–3 engines with ODC part 

number (P/N) 50J775 or P/N 50J930, 

installed. The NPRM published in the 

Federal Register on August 8, 2023 (88 

FR 53406). The NPRM was prompted by 

an updated analysis by the engine 

manufacturer, which determined that 

cracks on the ODC originated due to 

high stress in the area between Tt3 boss 

and thermocouple bracket boss. PW 

developed a modification to improve 

the surface area between Tt3 boss and
