Airworthiness Directives; Dassault Model Falcon 10 Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of 
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: 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.

ADDRESSES: For service information identified in this AD, contact 
Dassault Falcon Jet, P.O. Box 2000, South Hackensack, New Jersey 07606.

SUPPLEMENTARY INFORMATION:

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.

Costs of Compliance

    The following table provides the estimated costs for U.S. operators 
to comply with this AD. The average labor rate is $80 per work hour.

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.

Adoption of the Amendment

0
Accordingly, under the authority delegated to me by the Administrator, 
the FAA amends 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

0
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]

0
2. The Federal Aviation Administration (FAA) amends Sec.  39.13 by 
removing amendment 39-15188 (72 FR 51161, September 6, 2007) and by 
adding the following new airworthiness directive (AD):

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.

[[Page 54494]]

Compliance

    (e) You are responsible for having the actions required by this 
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 hose 
replacement 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.
