CFR Citation: 14 CFR Part 39

Docket ID: [Docket No. FAA-2008-0296; Directorate Identifier 2007-NM-307-AD; Amendment 39-15567; AD 2008-13-04]

RIN ID: RIN 2120-AA64

NOTICE: RULES

ACTION: Airworthiness Directives:

DOCUMENT ACTION: Final rule.

SUBJECT CATEGORY: Airworthiness Directives; Dassault Model Mystere-Falcon 20-C5, 20-D5, and 20-E5 Airplanes

DATES: This AD becomes effective July 24, 2008.

The Director of the Federal Register approved the incorporation by reference of a certain publication listed in this AD as of July 24, 2008.

DOCUMENT 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:

This Airworthiness Directive (AD) is prompted by the discovery on an inservice MystereFalcon 20C5 of a collapsed wing antiice flexible hose due to internal ply separation.

Consequences on the aircraft can be insufficient antiicing not detected by the monitoring system. Ice accretion on the wing might then occur and might jeopardize the aircraft flight performance and safety.
* * * * *
The unsafe condition is undetected excessive ice buildup on the wings, which could interfere with controllability of the airplane. We are issuing this AD to require actions to correct the unsafe condition on these products.

SUMMARY: Dassault Model Mystere-Falcon 20-C5, 20-D5, and 20-E5 Airplanes,

DOCUMENT BODY: [[Page 34850]]

SUPPLEMENTAL INFORMATION

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 March 13, 2008 (73 FR 13509). That NPRM proposed to correct an unsafe condition for the specified products. The MCAI states:

This Airworthiness Directive (AD) is prompted by the discovery on an inservice MystereFalcon 20C5 of a collapsed wing antiice flexible hose due to internal ply separation.

Consequences on the aircraft can be insufficient antiicing not detected by the monitoring system. Ice accretion on the wing might then occur and might jeopardize the aircraft flight performance and safety.

The present AD mandates replacement of the wing antiice flexible hoses by new ones of an improved design.
The unsafe condition is undetected excessive ice buildup on the wings, which could interfere with controllability of the airplane. 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 214 products of U.S. registry. We also estimate that it will take about 5 workhours per product to comply with the basic requirements of this AD. The average labor rate is $80 per workhour. Required parts will cost about $887 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 $275,418, or $1,287 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.

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: 20081304 Dassault Aviation (Formerly Avions Marcel Dassault Breguet Aviation (AMD/BA)): Amendment 3915567. Docket No. FAA2008 0296; Directorate Identifier 2007NM307AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective July 24, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Dassault Model MystereFalcon 20C5, 20 D5, and 20E5 airplanes, certificated in any category, all serial numbers.
Subject
(d) Air Transport Association (ATA) of America Code 30: Ice and Rain Protection.
Reason
(e) The mandatory continuing airworthiness information (MCAI) states:

This Airworthiness Directive (AD) is prompted by the discovery on an inservice MystereFalcon 20C5 of a collapsed wing antiice flexible hose due to internal ply separation.

Consequences on the aircraft can be insufficient antiicing not detected by the monitoring system. Ice accretion on the wing might then occur and might jeopardize the aircraft flight performance and safety.

The present AD mandates replacement of the wing antiice flexible hoses by new ones of an improved design.

The unsafe condition is undetected excessive ice buildup on the wings, which could interfere with controllability of the airplane. Actions and Compliance
(f) Within 7 months after the effective date of this AD, unless already done, do the following actions.
(1) Inspect to determine whether any wing antiice flexible hose having part number (P/N) FAL1006 or P/N ARM224A is installed. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number of the wing antiice flexible hose can be conclusively determined from that review. If any wing antiice flexible hose does not have P/N FAL1006 or P/N ARM224A, no further action is required by this AD for that hose, except as required by paragraph (f)(3) of this AD.
(2) Remove any wing antiice flexible hose having P/N FAL1006 or P/N ARM224A, and install a new hose having ESPA (brand) P/N 60503104509; in accordance with the Accomplishment Instructions of Dassault Service Bulletin F20775, dated July 9, 2007.
(3) As of the effective date of this AD, no person shall install any flexible hose having P/N FAL1006 or P/N ARM224A on any Model MystereFalcon 20C5, 20D5, or 20E5 airplane specified in the applicability of this AD.

FAA AD Differences
