ACTION: Final rule; request for
comments.
AGENCY:
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for all
Dassault Model Falcon 10 series
airplanes. This AD requires revising the
Limitations section of the airplane flight
manual (AFM) to include a statement
prohibiting flight into known or
forecasted icing conditions, and
installing a placard in the flight deck. In
lieu of the AFM revision and placard
installation, this AD allows identifying
the part number of each flexible hose in
the wing anti-icing system, performing
repetitive detailed inspections of each
hose for delamination, and performing
corrective actions if necessary. This AD
is prompted by a report of delamination
of the internal wall of a flexible hose in
the wing anti-icing system. We are
issuing this AD to prevent collapse of
the flexible hoses in the wing anti-icing
system, which could lead to insufficient
anti-icing capability and, if icing is
encountered in this situation, could
result in reduced controllability of the
airplane.
Effective April 26, 2005.
The incorporation by reference of a
certain publication listed in the AD is

SUPPLEMENTARY INFORMATION: The
´ ´
Direction Generale de l’Aviation Civile
(DGAC), which is the airworthiness
authority for France, notified the FAA
that an unsafe condition may exist on
all Dassault Model Falcon 10 series
E:\FR\FM\11APR1.SGM
11APR1
Federal Register / Vol. 70, No. 68 / Monday, April 11, 2005 / Rules and Regulations
airplanes. The DGAC advises that a
flexible hose in the wing anti-icing
system collapsed on a Dassault Model
Falcon 10 series airplane. The flexible
hoses supply hot air for anti-icing of the
inboard and outboard slats of the wing.
Investigation revealed that the hose
collapsed due to delamination of the
internal wall, which resulted in the
obstruction of airflow through the hose.
This condition, if not corrected, could
result in insufficient anti-icing
capability and, if icing is encountered in
this situation, cold result in reduced
controllability of the airplane.
Relevant Service Information
Dassault has issued Alert Service
Bulletin F10–A312, dated February 25,
2005. The alert service bulletin
describes procedures for identifying the
part number of the flexible hoses,
inspecting the internal walls of the
hoses for blistering (delamination), and
performing corrective actions. The
corrective actions include replacing any
hose that doesn’t have a certain part
number with a hose having the part
number specified in the service bulletin,
and replacing any damaged hose with a
new hose having the part number
specified in the service bulletin. The
DGAC mandated the alert service
bulletin and issued French emergency
airworthiness directive UF–2005–041,
issued February 25, 2005, to ensure the
continued airworthiness of these
airplanes in France.
FAA’s Determination and Requirements
of This AD
This airplane model is manufactured
in France and is type certificated for
operation in the United States under the
provisions of section 21.29 of the
Federal Aviation Regulations (14 CFR
21.29) and the applicable bilateral
airworthiness agreement. Pursuant to
this bilateral airworthiness agreement,
the DGAC has kept the FAA informed
of the situation described above. We
have examined the DGAC’s findings,
evaluated all pertinent information, and
determined that we need to issue an AD
for products of this type design that are
certificated for operation in the United
States. Therefore, we are issuing this AD
to prevent the collapse of flexible hoses
in the wing anti-icing system, which
could lead to insufficient anti-icing
capability and, if icing is encountered in
this situation, could result in reduced
controllability of the airplane.
This AD requires revising the
Limitations section of the airplane flight
manual (AFM) to include a statement
prohibiting flight into known or
forecasted icing conditions, and
installing a placard in the flight deck. In
VerDate jul<14>2003
16:26 Apr 08, 2005
Jkt 205001
lieu of the AFM revision and placard
installation, this AD allows identifying
the part number of each flexible hose in
the wing anti-icing system, performing
repetitive detailed inspections of each
hose for delamination, and performing
corrective actions if necessary, by
accomplishing the actions specified in
the service information described
previously. The AD also requires
sending the inspection results to the
airplane manufacturer. When the unsafe
condition addressed by an AD is likely
due to a manufacturer’s quality control
(QC) problem, a reporting requirement
is instrumental in ensuring that as much
information as possible can be gathered
regarding the extent and nature of the
QC problem or breakdown, especially in
cases where the data may not be
available through other established
means. This information is necessary to
ensure that proper corrective action will
be taken.
Difference Between the AD and French
Emergency Airworthiness Directive
If an operator chooses to do the AFM
revision and placard installation instead
of the repetitive inspection of the
flexible hoses, the French emergency
airworthiness directive mandates
performing the AFM revision before the
next flight of the airplane. This AD
allows operators 14 days after the
effective date of this AD to complete the
AFM revision. In developing an
appropriate compliance time for this
AD, we considered the DGAC’s
recommendation, as well as the degree
of urgency associated with the subject
unsafe condition. In light of these
factors, we find that a 14-day
compliance time represents an
appropriate interval of time for affected
airplanes to continue to operate without
compromising safety.
The DGAC is aware of this difference.
Clarification of Life Limits and
Repetitive Inspection Intervals
For the flexible hoses, the French
emergency airworthiness directive
references the existing life limit of 3,000
flight hours, which is in Chapter 5–40
of the Dassault Falcon 10 Airplane
Maintenance Manual. The French
emergency airworthiness directive
requires a revision to Chapter 5-40 to
include repetitive inspections of the
hoses. This AD is not requiring a change
to Chapter 5–40 since these inspections
are required by this AD. For operators
that choose to do the repetitive
inspections, this AD requires repetitive
inspections at intervals of 60 flight
cycles or 3 months, whichever is first.

Clarification of Type of Inspection
The ‘‘inspection’’ of the internal walls
of the flexible hoses specified in the
alert service bulletin is identified as a
‘‘detailed inspection’’ in this AD. We
have included the definition for a
detailed inspection in Note 1 of this AD.
Interim Action
This AD is considered to be interim
action. The inspection reports that are
required by this AD will enable the
manufacturer to obtain better insight
into the nature, cause, and extent of the
delamination of the internal walls of a
flexible hose, and eventually to develop
final action to address the unsafe
condition. Once final action has been
identified, we may consider further
rulemaking.
FAA’s Determination of the Effective
Date
An unsafe condition exists that
requires the immediate adoption of this
AD; therefore, providing notice and
opportunity for public comment before
the AD is issued is impracticable, and
good cause exists to make this AD
effective in less than 30 days.
Comments Invited
This AD is a final rule that involves
requirements that affect flight safety and
was not preceded by notice and an
opportunity for public comment;
however, we invite you to submit any
relevant written data, views, or
arguments regarding this AD. Send your
comments to an address listed under
ADDRESSES. Include ‘‘Docket No. FAA–
2005–20884; Directorate Identifier
2005–NM–051–AD’’ at the beginning of
your comments. We specifically invite
comments on the overall regulatory,
economic, environmental, and energy
aspects of the AD. We will consider all
comments received by the closing date
and may amend the AD in light of those
comments.
We will post all comments we
receive, without change, to https://
dms.dot.gov, including any personal
information you provide. We will also
post a report summarizing each
substantive verbal contact with FAA
personnel concerning this AD. Using the
search function of our docket Web site,
anyone can find and read the comments
in any of our dockets, including the
name of the individual who sent the
comment (or signed the comment on
behalf of an association, business, labor
union, etc.). You can review the DOT’s

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 have determined that this AD will
not have federalism implications under
Executive Order 13132. This AD will
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 the 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 AD. See the ADDRESSES section for
a location to examine the regulatory
evaluation.

AGENCY:
SUMMARY: The FAA is adopting a new
airworthiness directive (AD) for certain
Boeing Model 777–200 and –300 series
airplanes. This AD requires inspecting
the thrust reversers for damage of the
insulation blankets, the inner wall, and
the compression and drag link fittings;
and repair if necessary. This AD also
requires applying sealant to certain
areas of the thrust reverser. This AD is
prompted by two reports of thrust
reverser failure; investigation revealed
that the inner wall of the thrust
reversers had collapsed from exposure
to hot engine core compartment air. We
are issuing this AD to prevent failure of
a thrust reverser and adjacent
components and their consequent
separation from the airplane, which
could result in a rejected takeoff (RTO)
and cause asymmetric thrust and
consequent loss of control of the
VerDate jul<14>2003

airplane during reverse thrust operation.
If an RTO does not occur, these
separated components could cause
structural damage to the airplane or
damage to other airplanes and possible
injury to people on the ground.
DATES: Effective April 26, 2005.
The incorporation by reference of
certain publications listed in the AD is
approved by the Director of the Federal
Register as of April 26, 2005.

SUPPLEMENTARY INFORMATION: We have
received two reports indicating failure
of the thrust reversers during takeoff on
certain Boeing Model 777–200 and –300
series airplanes. Investigation of both
incidents revealed that the composite
inner wall of the thrust reverser
collapsed as a result of the migration of
hot engine core compartment air
underneath the insulation blankets,
which overheated the composite
structure. In the second incident, the
outer sleeve of the primary nozzle had
detached from the airplane and
impacted an automobile on the ground,
causing significant damage.
Investigation of the first incident
revealed that debris from the right
engine had departed the airplane and
was left on the runway. The flightcrew
was not aware of the failure until arrival
at the destination airport. Extensive
damage was found to the inner wall of
the thrust reverser, with large sections
of the composite structure missing. Both
failures occurred on airplanes that had
each accumulated more than 6,000 total
flight cycles. Subsequent inspection of
the thrust reversers on airplanes that
had accumulated between 6,000 and
9,000 total flight cycles indicated areas
of delamination and annealed
compression pads of the inner wall. The
cause of the delamination is exposure to
hot engine core compartment air, which
can also cause thermal damage to the
compression and drag link fittings.
These conditions, if not corrected, could
result in a rejected takeoff (RTO) and
cause asymmetric thrust and consequent
loss of control of the airplane during
reverse thrust operation. If an RTO does
not occur, these separated components
could cause structural damage to the
airplane or damage to other airplanes
and possible injury to people on the
ground.
Relevant Service Information
We have reviewed Boeing Alert
Service Bulletin 777–78A0059, dated
February 24, 2005. The service bulletin
describes procedures for one-time
detailed and special detailed
inspections of the thrust reversers, as
applicable, for damage of the insulation
blankets, inner wall, and compression
and drag link fittings; and repair if
necessary. The compliance times for the
inspections range from 3 months to 24
months, depending on the number of
total flight cycles on the airplane. The
damage includes over-temperature
conditions such as brown to blackened
scorching and disbonding. The repair
includes repair or replacement of any

Airworthiness Directives; Dassault Model Falcon 10 Series
Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for all
Dassault Model Falcon 10 series airplanes. This AD requires revising
the Limitations section of the airplane flight manual (AFM) to include
a statement prohibiting flight into known or forecasted icing
conditions, and installing a placard in the flight deck. In lieu of the
AFM revision and placard installation, this AD allows identifying the
part number of each flexible hose in the wing anti-icing system,
performing repetitive detailed inspections of each hose for
delamination, and performing corrective actions if necessary. This AD
is prompted by a report of delamination of the internal wall of a
flexible hose in the wing anti-icing system. We are issuing this AD to
prevent collapse of the flexible hoses in the wing anti-icing system,
which could lead to insufficient anti-icing capability and, if icing is
encountered in this situation, could result in reduced controllability
of the airplane.
DATES: Effective April 26, 2005.
The incorporation by reference of a certain publication listed in
the AD is approved by the Director of the Federal Register as of April
26, 2005.
We must receive comments on this AD by June 10, 2005.

SUPPLEMENTARY INFORMATION: The Direction G[eacute]n[eacute]rale de
l'Aviation Civile (DGAC), which is the airworthiness authority for
France, notified the FAA that an unsafe condition may exist on all
Dassault Model Falcon 10 series
[[Page 18283]]
airplanes. The DGAC advises that a flexible hose in the wing anti-icing
system collapsed on a Dassault Model Falcon 10 series airplane. The
flexible hoses supply hot air for anti-icing of the inboard and
outboard slats of the wing. Investigation revealed that the hose
collapsed due to delamination of the internal wall, which resulted in
the obstruction of airflow through the hose. This condition, if not
corrected, could result in insufficient anti-icing capability and, if
icing is encountered in this situation, cold result in reduced
controllability of the airplane.
Relevant Service Information
Dassault has issued Alert Service Bulletin F10-A312, dated February
25, 2005. The alert service bulletin describes procedures for
identifying the part number of the flexible hoses, inspecting the
internal walls of the hoses for blistering (delamination), and
performing corrective actions. The corrective actions include replacing
any hose that doesn't have a certain part number with a hose having the
part number specified in the service bulletin, and replacing any
damaged hose with a new hose having the part number specified in the
service bulletin. The DGAC mandated the alert service bulletin and
issued French emergency airworthiness directive UF-2005-041, issued
February 25, 2005, to ensure the continued airworthiness of these
airplanes in France.
FAA's Determination and Requirements of This AD
This airplane model is manufactured in France and is type
certificated for operation in the United States under the provisions of
section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and
the applicable bilateral airworthiness agreement. Pursuant to this
bilateral airworthiness agreement, the DGAC has kept the FAA informed
of the situation described above. We have examined the DGAC's findings,
evaluated all pertinent information, and determined that we need to
issue an AD for products of this type design that are certificated for
operation in the United States. Therefore, we are issuing this AD to
prevent the collapse of flexible hoses in the wing anti-icing system,
which could lead to insufficient anti-icing capability and, if icing is
encountered in this situation, could result in reduced controllability
of the airplane.
This AD requires revising the Limitations section of the airplane
flight manual (AFM) to include a statement prohibiting flight into
known or forecasted icing conditions, and installing a placard in the
flight deck. In lieu of the AFM revision and placard installation, this
AD allows identifying the part number of each flexible hose in the wing
anti-icing system, performing repetitive detailed inspections of each
hose for delamination, and performing corrective actions if necessary,
by accomplishing the actions specified in the service information
described previously. The AD also requires sending the inspection
results to the airplane manufacturer. When the unsafe condition
addressed by an AD is likely due to a manufacturer's quality control
(QC) problem, a reporting requirement is instrumental in ensuring that
as much information as possible can be gathered regarding the extent
and nature of the QC problem or breakdown, especially in cases where
the data may not be available through other established means. This
information is necessary to ensure that proper corrective action will
be taken.
Difference Between the AD and French Emergency Airworthiness Directive
If an operator chooses to do the AFM revision and placard
installation instead of the repetitive inspection of the flexible
hoses, the French emergency airworthiness directive mandates performing
the AFM revision before the next flight of the airplane. This AD allows
operators 14 days after the effective date of this AD to complete the
AFM revision. In developing an appropriate compliance time for this AD,
we considered the DGAC's recommendation, as well as the degree of
urgency associated with the subject unsafe condition. In light of these
factors, we find that a 14-day compliance time represents an
appropriate interval of time for affected airplanes to continue to
operate without compromising safety.
The DGAC is aware of this difference.
Clarification of Life Limits and Repetitive Inspection Intervals
For the flexible hoses, the French emergency airworthiness
directive references the existing life limit of 3,000 flight hours,
which is in Chapter 5-40 of the Dassault Falcon 10 Airplane Maintenance
Manual. The French emergency airworthiness directive requires a
revision to Chapter 5-40 to include repetitive inspections of the
hoses. This AD is not requiring a change to Chapter 5-40 since these
inspections are required by this AD. For operators that choose to do
the repetitive inspections, this AD requires repetitive inspections at
intervals of 60 flight cycles or 3 months, whichever is first.
Clarification of Type of Inspection
The ``inspection'' of the internal walls of the flexible hoses
specified in the alert service bulletin is identified as a ``detailed
inspection'' in this AD. We have included the definition for a detailed
inspection in Note 1 of this AD.
Interim Action
This AD is considered to be interim action. The inspection reports
that are required by this AD will enable the manufacturer to obtain
better insight into the nature, cause, and extent of the delamination
of the internal walls of a flexible hose, and eventually to develop
final action to address the unsafe condition. Once final action has
been identified, we may consider further rulemaking.
FAA's Determination of the Effective Date
An unsafe condition exists that requires the immediate adoption of
this AD; therefore, providing notice and opportunity for public comment
before the AD is issued is impracticable, and good cause exists to make
this AD effective in less than 30 days.
Comments Invited
This AD is a final rule that involves requirements that affect
flight safety and was not preceded by notice and an opportunity for
public comment; however, we invite you to submit any relevant written
data, views, or arguments regarding this AD. Send your comments to an
address listed under ADDRESSES. Include ``Docket No. FAA-2005-20884;
Directorate Identifier 2005-NM-051-AD'' at the beginning of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of the AD. We will consider
all comments received by the closing date and may amend the AD in light
of those comments.
We will post all comments we receive, without change, to https://
dms.dot.gov, including any personal information you provide. We will
also post a report summarizing each substantive verbal contact with FAA
personnel concerning this AD. Using the search function of our docket
Web site, anyone can find and read the comments in any of our dockets,
including the name of the individual who sent the comment (or signed
the comment on behalf of an association, business, labor union, etc.).

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 have determined that this AD will not have federalism
implications under Executive Order 13132. This AD will 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 the 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 AD. See the ADDRESSES section for a location to
examine the regulatory evaluation.

Affected ADs
(b) None.
Applicability
(c) This AD applies to all Dassault Model Falcon 10 series
airplanes, certificated in any category.
Unsafe Condition
(d) This AD was prompted by a report of delamination of the
internal wall of a flexible hose in the wing anti-icing system. The
FAA is issuing this AD to prevent the collapse of flexible hoses in
the wing anti-icing system, which could lead to insufficient anti-
icing capability and, if icing is encountered in this situation,
could result in reduced controllability of the airplane.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Repetitive Inspections, or Airplane Flight Manual (AFM) Revision and
Placard Installation
(f) Within 14 days after the effective date of this AD, perform
the actions specified in either paragraph (f)(1) or (f)(2) of this
AD:
(1) Revise the Limitations section of the Dassault Aviation
Falcon 10 AFM, and install a placard in the flight deck, to include
the following information.
``Flights into known or forecasted icing conditions are
prohibited.''
The AFM revision may be done by inserting a copy of this AD into the
AFM. Install the placard on the pedestal in clear view of the pilot.
(2) Determine the part number of each flexible hose installed in
the wing anti-icing system, perform a detailed inspection of the
internal walls of the hoses for delamination, and perform any
applicable corrective action, by accomplishing all of the applicable
actions specified in the Accomplishment Instructions of Dassault
Alert Service Bulletin F10-A312, dated February 25, 2005. If the
part number for any hose cannot be determined, before further
flight, replace that hose with a hose having part number (P/N)
FAL1005D. Any corrective action must be done before further flight.
Repeat the detailed inspection thereafter at intervals not to exceed
60 flight cycles or 3 months, whichever is first.
Note 1: When a statement identical to that in paragraph (f)(1)
of this AD has been included in the general revision of the AFM, the
general revision may be inserted into the AFM, and the copy of this
AD may be removed from the AFM.
Note 2: For the purposes of this AD, a detailed inspection is:
``An intensive examination of a specific item, installation, or
assembly to detect damage, failure, or irregularity. Available
lighting is normally supplemented with a direct source of good
lighting at an intensity deemed appropriate. Inspection aids such as
mirror, magnifying lenses, etc., may be necessary. Surface cleaning
and elaborate procedures may be required.''
(g) For airplanes on which the actions described in paragraph
(f)(1) are performed, doing the actions described in paragraph
(f)(2) is terminating action for the requirements of paragraph
(f)(1). Once the initial detailed inspection specified in paragraph
(f)(2) is performed, the AFM limitation and placard required by
paragraph (f)(1) may be removed.
Reporting Requirement
(h) At the applicable time specified in paragraph (h)(1) or
