Airworthiness Directives; Dassault Model Falcon 2000EX Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD) for the
products listed above. This proposed AD results from mandatory
continuing airworthiness information (MCAI) originated by an aviation
authority of another country to identify and correct an unsafe
condition on an aviation product. The MCAI describes the unsafe
condition as:
An internal review of design data has shown that the web of the
left hand side (LH) stringer 13 near frame 8 might have been
improperly trimmed on a few aircraft.
If not corrected, possible crack initiations could occur in the
upper stringer web, and therefore could impair the structural
strength of the adjacent door stop. This latent failure could
ultimately lead to the loss of redundancy of the door stops, thereby
affecting the structural integrity of the fuselage.
* * * * *
The proposed AD would require actions that are intended to address the
unsafe condition described in the MCAI.

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Community, has issued EASA
Airworthiness Directive 2008-0143, dated July 31, 2008 (referred to
after this as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:
An internal review of design data has shown that the web of the
left hand side (LH) stringer 13 near frame 8 might have been
improperly trimmed on a few aircraft.
If not corrected, possible crack initiations could occur in the
upper stringer web, and therefore could impair the structural
strength of the adjacent door stop. This latent failure could
ultimately lead to the loss of redundancy of the door stops, thereby
affecting the structural integrity of the fuselage.
Computational analysis has revealed a substantial reduced
fatigue life for the stringer abutting onto the improperly trimmed
web and has determined the need for an inspection and repair action
no later than the first ``C'' check.
To address this unsafe condition, the present Airworthiness
Directive (AD) mandates an inspection and a conditional rework or
replacement of the web of the LH stringer 13 between frames 7 and 8.
Required actions include measuring the trimmed length of the web,
inspecting for any sharp and unprotected edges of the web, and doing
corrective actions if necessary. Corrective actions include reworking
the web, applying protection to the web, and replacing the web, if
improperly trimmed. You may obtain further information by examining the
MCAI in the AD docket.
Relevant Service Information
Dassault has issued Mandatory Service Bulletin F2000EX-178, dated
July 1, 2008. The actions described in this service information are
intended to correct the unsafe condition identified in the MCAI.
[[Page 19028]]
FAA's Determination and Requirements of This Proposed AD
This product has been approved by the aviation authority of another
country, and is approved for operation in the United States. Pursuant
to our bilateral agreement with the State of Design Authority, we have
been notified of the unsafe condition described in the MCAI and service
information referenced above. We are proposing this AD because we
evaluated all pertinent information and determined an unsafe condition
exists and is likely to exist or develop on other products of the same
type design.
Differences Between This AD and the MCAI or Service Information
We have reviewed the MCAI and related service information and, in
general, agree with their substance. But we might have found it
necessary to use different words from those in the MCAI to ensure the
AD is clear for U.S. operators and is enforceable. In making these
changes, we do not intend to differ substantively from the information
provided in the MCAI and related service information.
We might also have proposed different actions in this AD from those
in the MCAI in order to follow FAA policies. Any such differences are
highlighted in a NOTE within the proposed AD.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 12 products of U.S. registry. We also estimate that
it would take about 1 work-hour per product to comply with the basic
requirements of this proposed AD. The average labor rate is $80 per
work-hour. Based on these figures, we estimate the cost of the proposed
AD on U.S. operators to be $960, or $80 per product.
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 determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would 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 this proposed
regulation:
1. Is not a ``significant regulatory action'' under Executive Order
12866;
2. Is not a ``significant rule'' under the 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 proposed AD and placed it in the AD docket.

The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
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]
2. The FAA amends Sec. 39.13 by adding the following new AD:
Dassault Aviation: Docket No. FAA-2009-0380; Directorate Identifier
2008-NM-153-AD.
Comments Due Date
(a) We must receive comments by May 27, 2009.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Dassault Model Falcon 2000EX airplanes,
certificated in any category, serial numbers 102 through 124
inclusive.
Subject
(d) Air Transport Association (ATA) of America Code 53:
Fuselage.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
An internal review of design data has shown that the web of the
left hand side (LH) stringer 13 near frame 8 might have been
improperly trimmed on a few aircraft.
If not corrected, possible crack initiations could occur in the
upper stringer web, and therefore could impair the structural
strength of the adjacent door stop. This latent failure could
ultimately lead to the loss of redundancy of the door stops, thereby
affecting the structural integrity of the fuselage.
Computational analysis has revealed a substantial reduced
fatigue life for the stringer abutting onto the improperly trimmed
web and has determined the need for an inspection and repair action
no later than the first ``C'' check.
To address this unsafe condition, the present Airworthiness
Directive (AD) mandates an inspection and a conditional rework or
replacement of the web of the LH stringer 13 between frames 7 and 8.
Required actions include measuring the trimmed length of the web,
inspecting for any sharp and unprotected edges of the web, and doing
corrective actions if necessary. Corrective actions include
reworking the web, applying protection to the web, and replacing the
web, if improperly trimmed.
Actions and Compliance
(f) Unless already done, do the following actions.
(1) At the later of the times in paragraphs (f)(1)(i) and
(f)(1)(ii) of this AD:
Perform a detailed visual inspection to detect any sharp and
unprotected edges of the web of the LH stringer 13 between frames 7
and 8, and measure the trimmed length of the web, in accordance with
the Accomplishment Instructions of Dassault Mandatory Service
Bulletin F2000EX-178, dated July 1, 2008.
(i) Before the accumulation of 3,750 total flight cycles, or
within 74 months since the date of issuance of the original French
airworthiness certificate or the date of issuance of the original
French export certificate of airworthiness, whichever occurs first.
(ii) Within 6 months after the effective date of this AD.
(2) If, during the inspection and measurement required by
paragraph (f)(1) of this AD, any sharp or unprotected edge is found,
or if the trimmed length is 1.57 inches (40 mm) or greater, before
further flight, do all applicable corrective actions, in accordance
with the Accomplishment Instructions of Dassault Mandatory Service
Bulletin F2000EX-178, dated July 1, 2008.
FAA AD Differences
Note: This AD differs from the MCAI and/or service information
as follows: No differences.
