RIN 2120–AA64
Airworthiness Directives; DASSAULT
AVIATION Airplanes
Federal Aviation
Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to adopt a new
airworthiness directive (AD) for certain
DASSAULT AVIATION Model
FALCON 2000, FALCON 2000EX,
MYSTERE–FALCON 900 and FALCON
900EX airplanes; and all Model
MYSTERE–FALCON 50 airplanes. This
proposed AD was prompted by reports
that collapse of the main landing gear
(MLG) could cause wing tank structure
failure, which could result in fuel
spillage and consequent fire hazard.
This proposed AD would require
modification of the wing fuel tanks in
the area of the wheel well. We are
proposing this AD to prevent fuel
spillage in the event of a MLG collapse,
and consequent fire hazard.
DATES: We must receive comments on
this proposed AD by November 26,
2012.

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 2011–0193,
dated October 5, 2011 (referred to after
this as ‘‘the MCAI’’), to correct an unsafe
condition for the specified products.
The MCAI states:
In service experience has shown that, in
case of main landing gear collapse due to
overloads during take off or landing (e.g.,
during high-speed runway excursions), the
wing tank structure can fail, leading to fuel
spillage. * * *
This condition, if not corrected, could
result, in case of main landing gear collapse,
in a fuel spillage which may constitute a fire
hazard.
To address this unsafe condition, Dassault
Aviation have developed a structural
modification of the wing fuel tanks in the
area of the wheel well which introduces a
dry bay by adding a sealed boundary in front
of the rear spar between ribs 4 and 5.
For the reasons described above, this
[EASA] AD requires accomplishment of the
above-mentioned modification for the Right
Hand (RH) and Left Hand (LH) wing fuel
tanks.
You may obtain further information by
examining the MCAI in the AD docket.
Relevant Service Information
Dassault Aviation has issued the
following service information. 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
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.
VerDate Mar<15>2010
15:15 Oct 09, 2012
Jkt 229001
Costs of Compliance
Based on the service information, we
estimate that this proposed AD would
affect about 753 products of U.S.
registry. We also estimate that it would
take about 640 work-hours per product
to comply with the basic requirements
of this proposed AD. The average labor
rate is $85 per work-hour. Required
parts would cost about $18,500 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 parts. 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
$54,893,700, or $72,900 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 that 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.
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, Incorporation by reference,
Safety.

Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
We propose to supersede two
existing airworthiness directives (AD)
that apply to certain The Boeing
Company Model 737–100, –200, –200C,
–300, –400, and –500 series airplanes.
The existing AD, for certain Model 737–
100, –200, and –200C series airplanes
currently requires repetitive inspections
of the aft end of each inboard flap track
of the wing outboard flap, and
corrective actions, if necessary. The
existing AD, for certain Model 737–100,
–200, –200C, –300, –400, and –500
series airplanes requires repetitive
inspections for cracks in the upper
flange of the inboard track at the rear
spar attachments of each outboard flap,
and corrective action, if necessary. That
AD also requires, for certain airplanes,
repetitive inspections for discrepancies
of the rear spar attachments and cracks
in the upper flange of the inboard track
at the rear spar attachment of each
outboard flap, and eventual rework of
the flap track assembly and rear spar
attachments, including replacement of
the flap track with a new track, if
necessary. Since we issued those ADs,
we have received reports that the work
sequence and procedures used during
track installation could also cause loose
SUMMARY:

or cracked tracks. This proposed AD
would require an inspection for damage
and stop-drill repairs along the flap
track; an inspection for damage,
cracking, and stop-drill repairs along the
track webs; and an inspection for
damage of the flap track web and
flanges, and corrective actions if
necessary. This proposed AD would
also require, for certain airplanes, an
inspection for signs of movement
between the tapered shim and anti-fret
strip, installation of the anti-fret strip,
and corrosion of the tapered shim and
anti-fret strip; an inspection for signs of
movement, cracks and corrosion where
the track is attached to the wing rear
spar; an inspection for cracking of the
outboard edge of the track; an
inspection for cracking of the inner edge
of the track; and related investigative
and corrective actions if necessary. This
proposed AD would also require
repetitive overhauls of the flap track and
repetitive post-overhaul inspections and
corrective actions if necessary; an
inspection to determine the part number
of the flap track assembly, and
replacement of affected parts if
necessary; and would also add airplanes
to the applicability. We are proposing
this AD to detect and correct cracking
and damage in the flap track, which
could cause loss of the outboard trailing
edge flap and consequent reduced
controllability of the airplane.
DATES: We must receive comments on
this proposed AD by November 26,
2012.

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 2011-0193, dated October 5, 2011 (referred to
after this as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:
In service experience has shown that, in case of main landing
gear collapse due to overloads during take off or landing (e.g.,
during high-speed runway excursions), the wing tank structure can
fail, leading to fuel spillage. * * *
This condition, if not corrected, could result, in case of main
landing gear collapse, in a fuel spillage which may constitute a
fire hazard.
To address this unsafe condition, Dassault Aviation have
developed a structural modification of the wing fuel tanks in the
area of the wheel well which introduces a dry bay by adding a sealed
boundary in front of the rear spar between ribs 4 and 5.
For the reasons described above, this [EASA] AD requires
accomplishment of the above-mentioned modification for the Right
Hand (RH) and Left Hand (LH) wing fuel tanks.
You may obtain further information by examining the MCAI in the AD
docket.
Relevant Service Information
Dassault Aviation has issued the following service information. 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 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.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 753 products of U.S. registry. We also estimate that
it would take about 640 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor rate is $85 per
work-hour. Required parts would cost about $18,500 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
parts. 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 $54,893,700, or $72,900 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 that 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this proposed AD and placed it in the AD docket.
