Federal Aviation Administration
14 CFR Part 39
[Docket No. FAA-2006-23886; Directorate Identifier 2005-NM-255-AD;
Amendment 39-14574; AD 2006-09-04]
RIN 2120-AA64
Airworthiness Directives; Dassault Model Falcon 900EX Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
certain Dassault Model Falcon 900EX airplanes. This AD requires
inspecting the number 2 engine left- and right-hand forward mounts for
missing rivets, and installing rivets if necessary. This AD results
from reports of two missing rivets in the front section of the central
engine mast discovered on airplanes in service and in production. We
are issuing this AD to detect and correct missing rivets in the front
section of the central engine mast, which could result in reduced
structural integrity of the central engine mast, possible separation of
the engine from the airplane during flight, and consequent loss of
control of the airplane.
DATES: This AD becomes effective June 7, 2006.
The Director of the Federal Register approved the incorporation by
reference of a certain publication listed in the AD as of June 7, 2006.
ADDRESSES: You may examine the AD docket on the Internet at http://dms.dot.gov
or in person at the Docket Management Facility, U.S.
Department of Transportation, 400 Seventh Street, SW., Nassif Building,
Room PL-401, Washington, DC.

Jersey 07606, for service information identified in this AD.

SUPPLEMENTARY INFORMATION:
Examining the Docket
You may examine the airworthiness directive (AD) docket on the
Internet at http://dms.dot.gov or in person at the Docket Management
Facility office between 9 a.m. and 5 p.m., Monday through Friday,
except Federal holidays. The Docket Management Facility office
(telephone (800) 647-5227) is located on the plaza level of the Nassif
Building at the street address stated in the ADDRESSES section.
Discussion
The FAA issued a notice of proposed rulemaking (NPRM) to amend 14
CFR part 39 to include an AD that would apply to certain Dassault Model
Falcon 900EX airplanes. That NPRM was published in the Federal Register
on February 15, 2006 (71 FR 7874). That NPRM proposed to require
inspecting the number 2 engine left- and right-hand forward mounts for
missing rivets, and installing rivets if necessary.
Comments
We provided the public the opportunity to participate in the
development of this AD. We received no comments 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.

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.

Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES

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
adding the following new airworthiness directive (AD):
2006-09-04 Dassault Aviation: Amendment 39-14574. Docket No. FAA-
2006-23886; Directorate Identifier 2005-NM-255-AD.
Effective Date
(a) This AD becomes effective June 7, 2006.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Dassault Model Falcon 900EX airplanes,
certificated in any category, having serial numbers 1 through 137
inclusive.
Unsafe Condition
(d) This AD results from reports of two missing rivets in the
front section of the central engine mast discovered on airplanes in
service and in production. We are issuing this AD to detect and
correct missing rivets in the front section of the central engine
mast, which could result in reduced structural integrity of the
central engine mast, possible separation of the engine from the
airplane during flight, and consequent loss of control of the
airplane.
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.
Service Bulletin References
(f) The term ``service bulletin,'' as used in this AD, means the
Accomplishment Instructions of Dassault Service Bulletin F900EX-220,
Revision 1, dated July 29, 2005. Although the service bulletin
referenced in this AD specifies to submit information to the
manufacturer, this AD does not include such a requirement.
Inspection for and Installation of Missing Rivets
(g) Prior to accumulating 7,500 total flight hours, or within 6
months after the effective date of this AD, whichever is later: Do a
general visual inspection of the number 2 engine left- and right-
hand forward mounts for missing rivets, in accordance with the
service bulletin. If any rivet is missing, before further flight,
install the new rivet, in accordance with the service bulletin.
Note 1:
For the purposes of this AD, a general visual inspection is: ``A
visual examination of an interior or exterior area, installation, or
assembly to detect obvious damage, failure, or irregularity. This
level of inspection is made from within touching distance unless
otherwise specified. A mirror may be necessary to ensure visual
access to all surfaces in the inspection area. This level of
inspection is made under normally available lighting conditions such
as daylight, hangar lighting, flashlight, or droplight and may
require removal or opening of access panels or doors. Stands,
ladders, or platforms may be required to gain proximity to the area
being checked.''
Inspections and Installations According to Previous Issue of Service
Bulletin
(h) Inspecting for and installing rivets is also acceptable for
compliance with the requirements of paragraph (g) of this AD if done
before the effective date of this AD in accordance with the
Accomplishment Instructions of Dassault Service Bulletin F900EX-220,
dated April 14, 2004.
Alternative Methods of Compliance (AMOCs)
(i)(1) The Manager, International Branch, ANM-116, Transport
Airplane Directorate, FAA, has the authority to approve AMOCs for
this AD, if requested in accordance with the procedures found in 14
CFR 39.19.
(2) Before using any AMOC approved in accordance with Sec.
39.19 on any airplane to which the AMOC applies, notify the
appropriate principal inspector in the FAA Flight Standards
Certificate Holding District Office.

(j) French airworthiness directive F-2005-066, dated April 27,
2005, also addresses the subject of this AD.
