Federal Aviation Administration
14 CFR Part 39
[Docket No. FAA-2008-0116; Directorate Identifier 2007-NM-257-AD]

Airworthiness Directives; Dassault Model Falcon 2000 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:
Wing anti ice telescopic tubes (P/N [part number] 5035-400 and
5035-500) ball joints were originally designed with high temperature
polymer (Kynel TM) sealing rings. Temperature induced
cracking of these rings associated with long term wear has been
encountered in a small number of cases. This degradation may lead to
binding of the ball joint and high swiveling forces which may result
in improper operation of the leading edge slats and also in failure
of the ball joint mounting bracket with possible friction on the
aileron control rod, which could lead, if combined with a failure of
the aileron emergency actuator, to an aileron jamming.
The unsafe condition is a jammed aileron, which results in reduced
controllability of the airplane. The proposed AD would require actions
that are intended to address the unsafe condition described in the
MCAI.
DATES: We must receive comments on this proposed AD by March 6, 2008.

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 2006-0276, dated September 6, 2006 (referred to
after this as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:
Wing anti ice telescopic tubes (P/N [part number] 5035-400 and
5035-500) ball joints were originally designed with high temperature
polymer (Kynel TM) sealing rings. Temperature induced
cracking of these rings associated with long term wear has been
encountered in a small number of cases. This degradation may lead to
binding of the ball joint and high swiveling forces which may result
in improper operation of the leading edge slats and also in failure
of the ball joint mounting bracket with possible friction on the
aileron control rod, which could lead, if combined with a failure of
the aileron emergency actuator, to an aileron jamming.
A replacement carbon based material has been defined by the
telescopic tube manufacturer Zodiac and can be applied per Zodiac
Service bulletins (SB) 5035-30-001 and 5035-30-002, resulting in P/N
re-designations 5035-600 Amdt.A and 5035-700 Amdt.A, respectively.
The purpose of this Airworthiness Directive (AD), by requiring
modification of the wing anti-ice telescopic tubes in accordance
with the Zodiac service bulletins, is to ensure that no old
definition sealing rings remain in operation beyond a life limit of
2,400 flight hours (FH) or 2,000 flight cycles (FC).
The unsafe condition is a jammed aileron, which results in reduced
controllability of the airplane. You may obtain further information by
examining the MCAI in the AD docket.
Relevant Service Information
Zodiac has issued Service Bulletins 5035-30-001 and 5035-30-002,
both dated April 15, 2002. The actions described in this service
information are intended to correct the unsafe condition identified in
the MCAI.
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
[[Page 6619]]
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 159 products of U.S. registry. We also estimate that
it would take about 4 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $80 per
work-hour. Required parts would cost about $1,423 per product. Where
the service information lists required parts costs that are covered
under warranty, we have assumed that there will be no charge for these
costs. As we do not control warranty coverage for affected parties,
some parties may incur costs higher than estimated here. Based on these
figures, we estimate the cost of the proposed AD on U.S. operators to
be $277,137, or $1,743 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Safety.
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-2008-0116; Directorate Identifier
2007-NM-257-AD.
Comments Due Date
(a) We must receive comments by March 6, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Dassault Model Falcon 2000 airplanes,
certificated in any category; all serial numbers; equipped with wing
anti-ice telescopic tubes having part number (P/N) 5035-400 or 5035-
500.
Subject
(d) Air Transport Association (ATA) of America Code 30: Ice and
rain protection.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
Wing anti ice telescopic tubes (P/N [part number] 5035-400 and
5035-500) ball joints were originally designed with high temperature
polymer (Kynel TM) sealing rings. Temperature induced
cracking of these rings associated with long term wear has been
encountered in a small number of cases. This degradation may lead to
binding of the ball joint and high swiveling forces which may result
in improper operation of the leading edge slats and also in failure
of the ball joint mounting bracket with possible friction on the
aileron control rod, which could lead, if combined with a failure of
the aileron emergency actuator, to an aileron jamming.
A replacement carbon based material has been defined by the
telescopic tube manufacturer Zodiac and can be applied per Zodiac
Service bulletins (SB) 5035-30-001 and 5035-30-002, resulting in P/N
re-designations 5035-600 Amdt.A and 5035-700 Amdt.A, respectively.
The purpose of this Airworthiness Directive (AD), by requiring
modification of the wing anti-ice telescopic tubes in accordance
with the Zodiac service bulletins, is to ensure that no old
definition sealing rings remain in operation beyond a life limit of
2,400 flight hours (FH) or 2,000 flight cycles (FC).
The unsafe condition is a jammed aileron, which results in
reduced controllability of the airplane.
Actions and Compliance
(f) Unless already done, do the following actions.
(1) At the later of the compliance times specified in paragraphs
(f)(1)(i) and (f)(1)(ii) of this AD, remove and modify the affected
tubes in accordance with instructions contained in Zodiac Service
Bulletins 5035-30-001 and 5035-30-002, both dated April 15, 2002.
(i) Before the telescopic tubes, P/N 5035-400 and 5035-500,
exceed the limit of 2,400 flight hours, or 2,000 flight cycles,
time-in-service since new, whichever occurs first.
(ii) At the earlier of the times specified in paragraphs
(f)(1)(ii)(A) and (f)(1)(ii)(B) of this AD.
(A) Within 330 flight hours after the effective date of this AD.
(B) Within 7 months after the effective date of this AD.
(2) As of 7 months after the effective date of this AD, no
person may install an affected telescopic tube P/N 5035-400 or 5035-
500 in any aircraft as a replacement part, unless it has been
modified in accordance with instructions contained in Zodiac Service
Bulletins 5035-30-001 and 5035-30-002, both dated April 15, 2002.
