14 CFR Part 39

[Docket No. FAA-2006-23886; Directorate Identifier 2005-NM-255-AD; 
Amendment 39-14574; AD 2006-09-04]

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.
    Contact Dassault Falcon Jet, P.O. Box 2000, South Hackensack, New 
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.

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.

Related Information

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

Material Incorporated by Reference

    (k) You must use Dassault Service Bulletin F900EX-220, Revision 
1, dated July 29, 2005, to perform the actions that are required by 
this AD, unless the AD specifies otherwise. The Director of the 
Federal Register approved the incorporation by reference of this 
document in accordance with 5 U.S.C. 552(a)
