AGENCY:
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:
This Airworthiness Directive (AD) is
issued following the discovery of a potential
chafing between the feeder bundle and the
right side partition wall separating the cabin
from the lavatory at frames 22/23. This
chafing may damage the feeder bundle and
cause a sustained smoke-generating shortcircuit between the feeder and the partition

wall made of resistive composite material.
Strong smoke and a difficult-to-localize
short-circuit may result in a hazardous
situation.
The unsafe condition is sustained
smoke in the cabin, which may lead to
reduced ability of the flightcrew to
operate the airplane. 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 2006–0270,
dated September 4, 2006 (referred to
after this as ‘‘the MCAI’’), to correct an
unsafe condition for the specified
products. The MCAI states:
This Airworthiness Directive (AD) is
issued following the discovery of a potential
chafing between the feeder bundle and the
right side partition wall separating the cabin
from the lavatory at frames 22/23. This
chafing may damage the feeder bundle and
cause a sustained smoke-generating shortcircuit between the feeder and the partition
wall made of resistive composite material.
Strong smoke and a difficult-to-localize
short-circuit may result in a hazardous
situation.
The unsafe condition is sustained
smoke in the cabin, which may lead to
reduced ability of the flightcrew to
operate the airplane. Corrective actions
include inspecting for damage of the
feeder cables, repairing any damaged
feeder cable, installing a protective
Teflon tube over the feeder cable
bundle, and modifying the partition
wall. You may obtain further
information by examining the MCAI in
the AD docket.

Differences Between This AD and the
MCAI or Service Information
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
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 38 products of U.S. registry.
We also estimate that it would take
about 3 work-hours per product to
comply with the basic requirements of
this proposed AD. The average labor
E:\FR\FM\31MRP1.SGM
31MRP1
16786
Federal Register / Vol. 73, No. 62 / Monday, March 31, 2008 / Proposed Rules
rate is $80 per work-hour. Required
parts would cost about $34 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 $10,412, or $274 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.
jlentini on PROD1PC65 with PROPOSALS
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.

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:
During a flight test performed on an EASy
aircraft, subsequently to an air data probe
failure, the crew realized that the Flight path
vectors and the Vertical speeds that were
displayed on pilot’s and co-pilot’s PDU
(primary display unit) were identically
wrong.
A review of the EASy architecture reveals
that * * * One single ADS unflagged air data
error may lead to the computation and
display on both pilot’s and co-pilot’s display
units of unnoticed and misleading flight
information.
At take-off or during go-around this
situation might considerably reduce flight
safety.

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:
This Airworthiness Directive (AD) is issued following the
discovery of a potential chafing between the feeder bundle and the
right side partition wall separating the cabin from the lavatory at
frames 22/23. This chafing may damage the feeder bundle and cause a
sustained smoke-generating short-circuit between the feeder and the
partition
[[Page 16785]]
wall made of resistive composite material. Strong smoke and a
difficult-to-localize short-circuit may result in a hazardous
situation.
The unsafe condition is sustained smoke in the cabin, which may lead to
reduced ability of the flightcrew to operate 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 April 30, 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 2006-0270, dated September 4, 2006 (referred to
after this as ``the MCAI''), to correct an unsafe condition for the
specified products. The MCAI states:
This Airworthiness Directive (AD) is issued following the
discovery of a potential chafing between the feeder bundle and the
right side partition wall separating the cabin from the lavatory at
frames 22/23. This chafing may damage the feeder bundle and cause a
sustained smoke-generating short-circuit between the feeder and the
partition wall made of resistive composite material. Strong smoke
and a difficult-to-localize short-circuit may result in a hazardous
situation.
The unsafe condition is sustained smoke in the cabin, which may
lead to reduced ability of the flightcrew to operate the airplane.
Corrective actions include inspecting for damage of the feeder cables,
repairing any damaged feeder cable, installing a protective Teflon tube
over the feeder cable bundle, and modifying the partition wall. You may
obtain further information by examining the MCAI in the AD docket.
Relevant Service Information
Dassault has issued the service information described in the
following table.

----------------------------------------------------------------------------------------------------------------
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.
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 38 products of U.S. registry. We also estimate that
it would take about 3 work-hours per product to comply with the basic
requirements of this proposed AD. The average labor
[[Page 16786]]
rate is $80 per work-hour. Required parts would cost about $34 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 $10,412, or $274 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-2008-0365; Directorate Identifier
2007-NM-274-AD.
Comments Due Date
(a) We must receive comments by April 30, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to the Dassault airplanes described in
paragraphs (c)(1) and (c)(2) of this AD, certificated in any
category.
(1) Model Myst[egrave]re-Falcon 900 airplanes, serial numbers
188 through 202 inclusive, except those on which both Dassault
Service Bulletins F900-358 and F900-359 have already been
implemented, or Modification M3891 has already been implemented.
(2) Model Falcon 900EX airplanes, serial numbers 82 through 146
inclusive, except those on which both Dassault Service Bulletins
F900EX-241 and F900EX-251 have already been implemented, or
Modification M3891 has already been implemented.
Subject
(d) Air Transport Association (ATA) of America Code 24:
Electrical Power.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
This Airworthiness Directive (AD) is issued following the
discovery of a potential chafing between the feeder bundle and the
right side partition wall separating the cabin from the lavatory at
frames 22/23. This chafing may damage the feeder bundle and cause a
sustained smoke-generating short-circuit between the feeder and the
partition wall made of resistive composite material. Strong smoke
and a difficult-to-localize short-circuit may result in a hazardous
situation.
The unsafe condition is sustained smoke in the cabin, which may lead
to reduced ability of the flightcrew to operate the airplane.
Corrective actions include inspecting for damage of the feeder
cables, repairing any damaged feeder cable, installing a protective
Teflon tube over the feeder cable bundle, and modifying the
partition wall.
Actions and Compliance
(f) Unless already done, do the following actions.
(1) For Model Myst[egrave]re-Falcon 900 airplanes: Do the
actions specified in paragraphs (f)(1)(i) and (f)(1)(ii) of this AD.
(i) Within 330 flight hours or 7 months after the effective date
of this AD, whichever occurs first, inspect for damage of the feeder
cable bundle at the right side partition wall at frames 22/23, and,
if no damage of any feeder cable is found, before further flight,
install a protective Teflon tube over the feeder cable bundle; in
accordance with the Accomplishment Instructions of Dassault Service
Bulletin F900-358, Revision 1, dated July 19, 2006. If chafing or
damage of any feeder cable is found, before further flight, repair
the feeder cable in accordance with the Accomplishment Instructions
of Dassault Service Bulletin F900-359, Revision 1, dated July 19,
2006; and install a protective Teflon tube over the feeder cable
bundle in accordance with Dassault Service Bulletin F900-359,
Revision 1, or Dassault Service Bulletin F900-358, Revision 1.
(ii) Within 3,750 flight cycles or 74 months after the effective
date of this AD, whichever occurs first, modify the right side
partition wall at frames 22/23; in accordance with the
Accomplishment Instructions of Dassault Service Bulletin F900-359,
Revision 1, dated July 19, 2006. Implementation of both Dassault
Service Bulletin F900-358 and Dassault Service Bulletin F900-359,
both Revision 1, both dated July 19, 2006, terminates the
requirements of this AD for Model Myst[egrave]re-Falcon 900
airplanes.
(2) For Model Falcon 900EX airplanes: Do the actions specified
in paragraphs (f)(2)(i) and (f)(2)(ii) of this AD.
(i) Within 330 flight hours or 7 months after the effective date
of this AD, whichever occurs first, inspect for damage of the feeder
cable bundle at the right side partition wall at frames 22/23, and,
if no such damage of any feeder cable is found, before further
flight, install a protective Teflon tube over the feeder cable
bundle; in accordance with the Accomplishment Instructions of
Dassault Service Bulletin F900EX-241, Revision 1, dated July 19,
2006. If any damage of any feeder cable is found, before further
flight, repair the feeder cable in accordance with the
Accomplishment Instructions of Dassault Service Bulletin F900EX-251,
Revision 1, dated July 19, 2006; and install a protective Teflon
tube over the feeder cable bundle in accordance with Dassault
Service Bulletin F900EX-251, Revision 1, or Dassault Service
Bulletin F900EX-241, Revision 1.
(ii) Within 3,750 flight cycles or 74 months after the effective
date of this AD, whichever occurs first, modify the right side
partition wall at frames 22/23, in accordance with the
Accomplishment Instructions of Dassault Service Bulletin F900EX-251,
Revision 1, dated July 19, 2006. Implementation of both Dassault
Service Bulletin F900EX-241 and Dassault Service Bulletin F900EX-
251, both Revision 1, both dated July 19, 2006, terminates the
requirements of this AD for Model Falcon 900EX airplanes.
