14 CFR Part 39

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

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

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.

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:
