AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule. 

SUMMARY: The FAA is adopting a new 

airworthiness directive (AD) for all 

Dassault Aviation Model FALCON 7X 

airplanes. This AD was prompted by 

reports of excessive thickness of the 

trailing edge of certain ailerons, which 

may affect the assembly of the rear spar 

with the lower and upper skins. This 

AD requires a one-time ultrasonic or 

visual inspection of the aileron rear spar 

and trailing edge areas, and applicable 

corrective actions, 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 October 23, 

2024. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD

SUPPLEMENTARY INFORMATION: 

Background 

The FAA issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 by adding an AD that would 

apply on all Dassault Aviation Model 

FALCON 7X airplanes. The NPRM 

published in the Federal Register on 

May 23, 2024 (89 FR 45612). The NPRM 

was prompted by AD 2024–0076, dated 

March 19, 2024, issued by EASA, which 

is the Technical Agent for the Member 

States of the European Union (EASA AD 

2024–0076) (also referred to as the 

MCAI). The MCAI states that excessive 


khammond on DSKJM1Z7X2PROD with RULES
76402 Federal Register / Vol. 89, No. 181 / Wednesday, September 18, 2024 / Rules and Regulations 

thickness was found on the trailing edge 

of certain ailerons, which may affect the 

assembly of the rear spar with the lower 

and upper skins. The unsafe condition, 

if not addressed, could result in reduced 

structural integrity of the aileron. 

In the NPRM, the FAA proposed to 

require a one-time ultrasonic or visual 

inspection of the aileron rear spar and 

trailing edge areas, and applicable 

corrective actions, as specified in EASA 

AD 2024–0076. 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–2024–1473. 

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. 

Material Incorporated by Reference 

Under 1 CFR Part 51 

EASA AD 2024–0076 specifies 

procedures for one-time ultrasonic and 

visual inspections for discrepancies 

(excessive paint thickness) of the aileron 

rear spar and trailing edge areas, and 

repair of discrepant 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 160 airplanes of U.S. registry. 

The FAA estimates the following costs 

to comply with this AD: 

ESTIMATED COSTS FOR REQUIRED ACTIONS

Labor cost Parts cost Cost per 

product 

Cost on U.S. 

operators 

21 work-hours × $85 per hour = $1,785 ..................................................................................... $324 $2,109 $337,440 

The FAA estimates the following 

costs to do any necessary on-condition 

action that would be required based on 

the results of any required actions. The 

FAA has no way of determining the 

number of aircraft that might need this 

on-condition action: 

ESTIMATED COSTS OF ON-CONDITION ACTIONS

Labor cost Parts cost Cost per product 

11 work-hours × $85 per hour = $935 .............................................................................................................. $296 $1,231 

The FAA has included all known 

costs in its cost estimate. According to 

the manufacturer, however, some or all 

of the costs of this AD may be covered 

under warranty, thereby reducing the 

cost impact on affected operators. 

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. 

List of Subjects in 14 CFR Part 39
