Airworthiness Directives; Dassault Aviation Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to adopt a new airworthiness directive (AD)
for
certain Dassault Aviation Model MYSTERE-FALCON 900, FALCON 900EX,

Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the Member States of the European Union, has issued EASA
Airworthiness Directive 2017-0106, dated June 19, 2017 (referred to
after this as the Mandatory Continuing Airworthiness Information, or
"the MCAI"), to correct an unsafe condition for certain Dassault
Aviation Model MYSTERE-FALCON 900, FALCON 900EX, FALCON 2000, and
FALCON 2000EX airplanes. The MCAI states:
On some aeroplanes in-service, the screw of the slat mechanical
stop assembly on slat tracks #6, #7 and #8 was found loose. In some
cases, a puncture was found in the fuel cap. The results of the
technical investigations concluded that the most probable reason for
these events was improper installation of the lock washers on the
screws during production or maintenance.
This condition, if not detected and corrected, could lead to
structural damage to the wing front spar, and consequent fuel
leakage, possibly resulting in an uncontrolled fire.
To address this potential unsafe condition, Dassault issued
[Service Bulletin] SB F900-460 Revision 1, SB F900EX-508 Revision 3,
SB F2000-433 Revision 1, and SB F2000EX-386 Revision 3 (hereafter
collectively referred as `the applicable SB' in this [EASA] AD), as
applicable to aeroplane type/model, to provide inspection
instructions.
For the reasons described above, this [EASA] AD requires a one-
time [general visual] inspection of the slat tracks #6, #7 and #8 to
verify the tightening torque of the screw and proper lock washer
installation and, depending on findings, accomplishment of
applicable corrective action(s).
Applicable corrective actions include replacement, if necessary.
You may examine the MCAI in the AD docket on the Internet at http://
www.regulations.gov by searching for and locating Docket No. FAA-2017-
0909.
Related Service Information Under 1 CFR Part 51
Dassault Aviation has issued the following service information.
Dassault Service Bulletin F900-460, Revision 1, dated February 10, 2017
Dassault Service Bulletin F900EX-508, Revision 3, dated February 10, 2017
Dassault Service Bulletin F2000-433, Revision 1, dated February 10, 2017
Dassault Service Bulletin F2000EX-386, Revision 3, dated February 10,
2017
This service information describes procedures for doing a one-time
general visual inspection of the screw on the affected slat tracks, and
replacement if necessary. These documents are distinct since they apply
to different airplane models. The service information is reasonably
available because the interested parties have access to it through
their normal course of business or by the means identified in the
ADDRESSES section.
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 these same
type designs.
Costs of Compliance
We estimate that this proposed AD affects 65 airplanes of U.S. registry.
We estimate the following costs to comply with this proposed AD:
Estimated Costs
Action |
Labor cost |
Parts cost |
Cost per product |
Cost on U.S. operators |
Inspection |
4 work-hours x $85 per hour =
$340 |
$0 |
$340 |
$22,100 |
We estimate the following costs to
do any necessary replacements
that would be required based on the results of the proposed inspection.
We have no way of determining the number of aircraft that might need
this replacement:
On-Condition Costs
Action |
Labor cost |
Parts cost |
Cost per product |
Replacement |
6 work-hours x $85 per hour =
$510 |
$15 |
$525 |
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.
This proposed AD is issued in accordance with authority delegated
by the Executive Director, Aircraft Certification Service, as
authorized by FAA Order 8000.51C. In accordance with that order,
issuance of ADs is normally a function of the Compliance and
Airworthiness Division, but during this transition period, the
Executive Director has delegated the authority to issue ADs applicable
to transport category airplanes to the Director of the System Oversight
Division.
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);
3. Will not affect intrastate aviation in Alaska; and
4. 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, 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 airworthiness
directive (AD):
