We agree to change the AD to reflect the current service information. Revision 1 of the service information contains an editorial change that does not affect the procedures. Table 1 of paragraph (f) of the AD has been changed accordingly, and we have added new paragraph (g) and Table 2 to the AD to give credit for actions performed according to the original versions of the service information.

Conclusion

We reviewed the available data, including the comment received, and determined that air safety and the public interest require adopting the AD with the change described previously. We determined that this change will not increase the economic burden on any operator or increase the scope of the AD.
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 335 products of U.S. registry. We also estimate that it will take 4 workhours per product to comply with the basic requirements of this AD. The average labor rate is $80 per workhour. Based on these figures, we estimate the cost of this AD to the U.S. operators to be $107,200, or $320 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 under the criteria of the Regulatory Flexibility Act.

We prepared a regulatory evaluation of the estimated costs to comply with this AD and placed it in the AD docket.

Examining the AD Docket

You may examine the AD docket on the Internet at http:// www.regulations.gov; or in person at the Docket Operations office between 9 a.m. and 5 p.m., Monday through Friday, except Federal holidays. The AD docket contains the NPRM, the regulatory evaluation, any comments received, and other information. The street address for the Docket Operations office (telephone (800) 6475527) is in the ADDRESSES section. Comments will be available in the AD docket shortly after receipt.

List of Subjects in 14 CFR Part 39

Air transportation, Aircraft, Aviation safety, Incorporation by reference, Safety.
Adoption of the Amendment
Accordingly, under the authority delegated to me by the Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:

Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. The FAA amends Sec. 39.13 by adding the following new AD: AD 20082205 Dassault Aviation: Amendment 3915700. Docket No. FAA 20080729; Directorate Identifier 2008NM052AD.
[[Page 67376]]
Effective Date
(a) This airworthiness directive (AD) becomes effective December 19, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Dassault Model MystereFalcon 900 airplanes from serial number (S/N) 1 to 200 inclusive; Model Falcon 900EX airplanes from S/N 1 to 129 inclusive; and Model Falcon 2000 airplanes from S/N 1 to 210 inclusive; when fitted with a third crew member control panel; certificated in any category.
Subject
(d) Air Transport Association (ATA) of America Code 25: Equipment/Furnishings.
Reason
(e) The mandatory continuing airworthiness information (MCAI) states:

This Airworthiness Directive (AD) is issued following the discovery of a potential chafing between the rheostat of the 3rd crew member control panel reading light and the air gasper flexible hose, or with the electrical wires nearby. If le[f]t uncorrected, this chafing may expose the metallic spiral armature of the flexible hose, or damage the electrical wires insulation, which could result in a shortcircuit generating sustained overheating and smoke emission.

This AD requires an inspection of the air gasper installation in the 3rd crew control panel of the LH [lefthand]and RH [right hand]crew closet for interference and damage and applicable related corrective actions.
The corrective actions include replacing the flexible hose and installing ROUNDIT insulation sleeving to the wires near the rheostat.
Actions and Compliance
(f) Unless already done: Within 7 months after the effective date of this AD, do a detailed inspection of the air gasper installation in the 3rd crew member control panel of the lefthand and righthand crew closet for interference and damage, and do all applicable related corrective actions as instructed in the Accomplishment Instructions of the applicable service information listed in Table 1 of this AD. Corrective actions must be done before further flight.
