Airworthiness Directives; Dassault 

Model Falcon 2000EX Airplanes 

AGENCY: Federal Aviation 

Administration (FAA), Department of 

Transportation (DOT). 

ACTION: Final rule. 

SUMMARY: We are adopting a new 

airworthiness directive (AD) for the 

products listed above. This AD results 

from mandatory continuing 

airworthiness information (MCAI) 

originated by an aviation authority of 

another country to identify and correct 

an unsafe condition on an aviation 

product. The MCAI describes the unsafe 

condition as: 

During approach, a Falcon 2000EX 

operator experienced a temporary loss of the 

4 Electronic Flight Instrumentation System 

(EFIS) display units followed by a 

consecutive restart of the avionics. During 

initial investigation, a loose connection on 

the DC load distribution system was 

discovered and determined to be the root 

cause of this event. However, further analysis 

pointed out that large electrical transients on 

the essential bus bar may possibly cause 

simultaneous and temporary power shortage 

on both sides of the electrical system. 

This Airworthiness Directive (AD) * * * 

action is necessary to prevent a momentary 

loss of data on the EFIS screens, which could 

lead to the pilot’s loss of situational 

awareness during initial climb or approach/ 

landing, and possibly result in reduced 

control of the airplane. * * * 

We are issuing this AD to require 

actions to correct the unsafe condition 

on these products. 

DATES: This AD becomes effective 

September 9, 2008. 

The Director of the Federal Register 

approved the incorporation by reference 

of a certain publication listed in this AD 

as of September 9, 2008.

SUPPLEMENTARY INFORMATION: 

Discussion 

We issued a notice of proposed 

rulemaking (NPRM) to amend 14 CFR 

part 39 to include an AD that would 

apply to the specified products. That 

NPRM was published in the Federal 

Register on May 20, 2008 (73 FR 29091). 

That NPRM proposed to correct an 

unsafe condition for the specified 

products. The MCAI states: 

During approach, a Falcon 2000EX 

operator experienced a temporary loss of the 

4 Electronic Flight Instrumentation System 

(EFIS) display units followed by a 

consecutive restart of the avionics. During 

initial investigation, a loose connection on 

the DC load distribution system was 

discovered and determined to be the root 

cause of this event. However, further analysis 

pointed out that large electrical transients on 

the essential bus bar may possibly cause 

simultaneous and temporary power shortage 

on both sides of the electrical system. 

This Airworthiness Directive (AD) requires 

a wiring modification of the GCUs (Generator 

Control Units) to increase the electrical 

system robustness. This action is necessary to 

prevent a momentary loss of data on the EFIS 

screens, which could lead to the pilot’s loss 

of situational awareness during initial climb 

or approach/landing, and possibly result in 

reduced control of the airplane. This action 

is intended to address the identified unsafe 

condition. 

You may obtain further information by 

examining the MCAI in the AD docket. 

Comments 

We gave the public the opportunity to 

participate in developing this AD. We 

received no comments on the NPRM or 

on the determination of the cost to the 

public. 

Conclusion 

We reviewed the available data and 

determined that air safety and the 

public interest require adopting the AD 

as proposed. 

Differences Between This AD and the 

MCAI or Service Information 

We have reviewed the MCAI and 

related service information and, in 

general, agree with their substance. But 

we might have found it necessary to use 

different words from those in the MCAI 

to ensure the AD is clear for U.S. 

operators and is enforceable. In making 

these changes, we do not intend to differ 

substantively from the information 

provided in the MCAI and related 

service information. 

We might also have required different 

actions in this AD from those in the 

MCAI in order to follow our FAA 

policies. Any such differences are 

highlighted in a Note within the AD. 

Costs of Compliance 

We estimate that this AD will affect 

about 57 products of U.S. registry. We 

also estimate that it will take about 8 

work-hours per product to comply with 

the basic requirements of this AD. The 

average labor rate is $80 per work-hour. 

Required parts will cost about $0 per 

product. Where the service information 

lists required parts costs that are 

covered under warranty, we have 

assumed that there will be no charge for 

these parts. As we do not control 

warranty coverage for affected parties, 

some parties may incur costs higher 

than estimated here. Based on these 

figures, we estimate the cost of this AD 

to the U.S. operators to be $36,480, or 

$640 per product. 

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. 

We are 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 

We determined that 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 this AD: 

1. Is not a ‘‘significant regulatory 

action’’ under Executive Order 12866; 

2. Is not a ‘‘significant rule’’ under the 

DOT Regulatory Policies and Procedures 

(44 FR 11034, February 26, 1979); and 

3. Will not have a significant 

economic impact, positive or negative, 

on a substantial number of small entities

Adoption of the Amendment 

■ Accordingly, under the authority 

delegated to me by the Administrator, 

the FAA amends 14 CFR part 39 as 

follows: 

PART 39—AIRWORTHINESS 

DIRECTIVES 

■ 1. The authority citation for part 39 

continues to read as follows: 

Authority: 49 U.S.C. 106(g), 40113, 44701. 

§ 39.13 [Amended] 

■ 2. The FAA amends § 39.13 by adding 

the following new AD: 

2008–16–08 Dassault Aviation: 

Amendment 39–15626. Docket No. 

FAA–2008–0557; Directorate Identifier 

2007–NM–364–AD. 

Effective Date 

(a) This airworthiness directive (AD) 

becomes effective September 9, 2008. 

Affected ADs 

(b) None. 

Applicability 

(c) This AD applies to Dassault Model 

Falcon 2000EX airplanes from serial number 

1 to 107 inclusive, certificated in any

consecutive restart of the avionics. During 

initial investigation, a loose connection on 

the DC load distribution system was 

discovered and determined to be the root 

cause of this event. However, further analysis 

pointed out that large electrical transients on 

the essential bus bar may possibly cause 

simultaneous and temporary power shortage 

on both sides of the electrical system. 

This Airworthiness Directive (AD) requires 

a wiring modification of the GCUs (Generator 

Control Units) to increase the electrical 

system robustness. This action is necessary to 

prevent a momentary loss of data on the EFIS 

screens, which could lead to the pilot’s loss 

of situational awareness during initial climb 

or approach/landing, and possibly result in 

reduced control of the airplane. This action 

is intended to address the identified unsafe 

condition.
