AD 2008-19-08

The FAA is superseding an existing airworthiness directive (AD), which applies to all Avions Marcel Dassault-Breguet Model Falcon 10 airplanes. That AD currently requires either revising the airplane flight manual and installing a placard in the flight deck to prohibit flight into known or forecasted icing conditions, or repetitively inspecting for delamination of the flexible hoses in the wing (slat) anti-icing system and performing corrective actions if necessary. The existing AD also requires replacement of the flexible hoses installed in the slat anti-icing systems, which ends the repetitive inspections. This new AD continues to require replacement of the flexible hoses installed in the slat anti-icing systems with new hoses, but at intervals defined in flight hours instead of flight cycles. This AD results from information we received from operators and the airplane manufacturer indicating that the repetitive interval for the required replacement deviated from the referenced service information. We are issuing this AD to prevent collapse of the flexible hoses in the slat anti-icing system, which could lead to insufficient anti-icing capability and, if icing is encountered in this situation, could result in reduced controllability of the airplane.

DATES: This AD becomes effective October 27, 2008.
On October 11, 2007 (72 FR 51161, September 6, 2007), the Director of the Federal Register approved the incorporation by reference of Dassault Service Bulletin F10-313, Revision 1, dated May 10, 2006.

Final rule.

2008-19-08 Dassault Aviation (Formerly Avions Marcel Dassault- Breguet Aviation (AMD/BA)): Amendment 39-15675. Docket No. FAA-2008- 0674; Directorate Identifier 2008-NM-086-AD.

Effective Date

(a) This AD becomes effective October 27, 2008.

Affected ADs

(b) This AD supersedes AD 2007-18-08.

Applicability

(c) This AD applies to all Dassault Model Falcon 10 airplanes, certificated in any category.

Unsafe Condition

(d) This AD results from information we received from operators and the airplane manufacturer indicating that the repetitive interval for the required replacement deviated from the referenced service information. We are issuing this AD to prevent collapse of the flexible hoses in the slat anti-icing system, which could lead to insufficient anti-icing capability and, if icing is encountered in this situation, could result in reduced controllability of the airplane.

Compliance

(e) You are responsible for having the actions required bythis AD performed within the compliance times specified, unless the actions have already been done.

Certain Requirements of AD 2007-18-08

Hose Replacement

(f) Within 330 flight hours or 7 months after October 11, 2007 (the effective date of AD 2007-18-08), whichever occurs first: Replace the flexible hoses installed in the slat anti-icing system with new hoses having part number (P/N) FAL1007, in accordance with the Accomplishment Instructions of Dassault Service Bulletin F10- 313, Revision 1, dated May 10, 2006. Repeat the hose replacement thereafter at intervals not to exceed 700 flight cycles, except as provided by paragraph (h) of this AD.
(g) Replacement of a hose before October 11, 2007, in accordance with Dassault Service Bulletin F10-313, dated August 10, 2005, is acceptable for compliance with the requirements of paragraph (f) of this AD.

New Requirements of This AD:

New Repetitive Interval

(h) As of the effective date of this AD, repeat the hosereplacement required by paragraph (f) of this AD within 700 flight hours since the last replacement, or within 100 flight hours after the effective date of this AD, whichever occurs later, and thereafter at intervals not to exceed 700 flight hours.

Alternative Methods of Compliance (AMOCs)

(i)(1) The Manager, International Branch, ANM-116, FAA, ATTN: Tom Rodriguez, Aerospace Engineer, FAA, Transport Airplane Directorate, 1601 Lind Avenue, SW., Renton, Washington 98057-3356; telephone (425) 227-1137; fax (425) 227-1149; has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19.
(2) To request a different method of compliance or a different compliance time for this AD, follow the procedures in 14 CFR 39.19. Before using any approved AMOC on any airplane to which the AMOC applies, notify your appropriate principal inspector (PI) in the FAA Flight Standards District Office (FSDO), or lacking a PI, your local FSDO.

Discussion

The FAA issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that supersedes AD 2007-18-08, amendment 39-15188 (72 FR 51161, September 6, 2007). The existing AD applies to all Avions Marcel Dassault-Breguet Model Falcon 10 airplanes. That NPRM was published in the Federal Register on June 27, 2008 (73 FR 36473). That NPRM proposed to continue to require either revising the airplane flight manual and installing a placard in the flight deck to prohibit flight into known or forecasted icing conditions, or repetitively inspecting for delamination of the flexible hoses in the wing (slat) anti-icing system and performing corrective actions if necessary. That NPRM also proposed to require replacement of the flexible hoses installed in the slat anti-icing systems with new hoses, but at intervals defined in flight hours instead of flight cycles.

Comments

We provided the public the opportunity to participate in the development of this AD. No comments have been received on the NPRM or on the determination of the cost to the public.

Conclusion

We have carefully reviewed the available data and determined that air safety and the public interest require adopting the AD as proposed.

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 have 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 that this AD:
(1) Is not a "significant regulatory action'' under Executive Order 12866;
(2) Is not a "significant rule'' under 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. See the ADDRESSES section for a location to examine the regulatory evaluation.
