rwilkins on PROD1PC63 with PROPOSALS
Over the years, several Fokker 100 (F28
Mark 0100) operators reported that a MLG
(main landing gear) wheel fell off during
regular operation of the aircraft. These
incidents occurred due to a missing spacer,
which had inadvertently not been installed
during a previous wheel change. Omitting
the installation of the wheel spacer allows
the wheel to move sideways along the axle,
which subsequently leads to bearing failure,
followed by loss of the wheel. Investigation
by Fokker and Messier-Dowty has shown that
two separate items, the spacer and the axle
nut, can be replaced by a single axle-nut/
spacer assembly, to prevent the possibility of
omitting the spacer. In 1995, Messier-Dowty
issued Service Bulletin (SB) F100–32–72 to
make sure that the operator does not
assemble the axle nut without the spacer.
Fokker subsequently issued SB F100–32–096
to notify Fokker 100 operators of the
(optional) Messier-Dowty SB’s existence. At
a later stage, Fokker revised the SB to the
status of ‘‘recommended’’. In spite of all this
attention to the spacer problem, wheel losses
are still being reported due to missing wheel
nut spacers. This condition, if not corrected,
may lead to further wheel loss incidents,
each of which could conceivably result in
loss of control of the aircraft during the takeoff run, landing rollout or taxiing operations.
Since a potentially unsafe condition has been
identified that may exist or develop on
aircraft of the same type design, this
Airworthiness Directive requires the
replacement of the axle-nut and spacer with
an integrated axle-nut/spacer assembly. In
addition, the Aircraft Maintenance Manual
(AMM) and Illustrated Parts Catalogue (IPC)
must be amended to prevent reversal to a
separate axle-nut and spacer installation
during a subsequent wheel change.
Actions and Compliance
(f) Unless already done, do the following
actions.
(1) Within 12 months after the effective
date of this AD, replace each MLG wheel
axle-nut and spacer with an integrated axlenut/spacer assembly in accordance with the
Accomplishment Instructions of MessierDowty Service Bulletin F100–32–72,
Revision 1, dated March 5, 2007.
Note 1: Fokker 70/100 Service Letter 102,
Revision 1, dated February 12, 1998; and
Fokker Service Bulletin SBF100–32–096,
Revision 2, dated April 29, 2005, also pertain
to this subject.
(2) As of 12 months after the effective date
of this AD, no person may install an axle nut
having part number (P/N) 201072670 or
alternate P/N 201072765, or any spacer
having P/N 201072699, on any airplane. Only
axle nut subassemblies having P/N
201251273 or P/N 201650216 may be
installed.
(3) Actions accomplished before the
effective date of this AD in accordance with
Messier-Dowty Service Bulletin F100–32–72,
dated January 25, 1995, are considered
acceptable for compliance with the
corresponding action specified in this AD.

ACTION: Notice of proposed rulemaking
(NPRM).
AGENCY:
SUMMARY: The FAA proposes to
supersede an existing airworthiness
directive (AD) that applies to all
Dassault Model Falcon 2000, MystereFalcon 900, Falcon 900EX, Fan Jet
Falcon, Mystere-Falcon 50, MystereFalcon 20, Mystere-Falcon 200, and
Falcon 10 series airplanes. The existing
AD currently requires repetitive tests
and inspections to detect discrepancies
of the overwing emergency exit, and
corrective action if necessary. This
proposed AD would expand the
applicability of the existing AD and
extend the repetitive test and inspection
interval for all airplanes. This proposed
AD results from reports of incorrect
operation of the overwing emergency
exit due to interference between the
emergency exit and the interior
accommodation. We are proposing this
AD to prevent failure of the overwing
emergency exits to open, and
consequent injury to passengers or crew
members during an emergency
evacuation.
DATES: We must receive comments on
this proposed AD by September 17,
2007.

Discussion
On June 9, 2000, we issued AD 2000–
12–15, amendment 39–11793 (65 FR
37480, June 15, 2000), for all Dassault
Model Falcon 2000, Mystere-Falcon
900, Falcon 900EX, Fan Jet Falcon,
Mystere-Falcon 50, Mystere-Falcon 20,
Mystere-Falcon 200, and Falcon 10
series airplanes. That AD requires
repetitive tests and inspections to detect
discrepancies of the overwing
emergency exit, and corrective action if
necessary. That AD resulted from
issuance of mandatory continuing
airworthiness information by a foreign
civil airworthiness authority. We issued
that AD to prevent failure of the
overwing emergency exits to open, and
consequent injury to passengers or crew
members during an emergency
evacuation.
Actions Since Existing AD Was Issued
Since we issued AD 2000–12–15, the
European Aviation Safety Agency
(EASA), which is the Technical Agent
for the Member States of the European
Community, has issued the following
EASA airworthiness directives, all dated
June 7, 2006:
• 2006–0147 (for Model Falcon 10
airplanes);
• 2006–0148 (for Model Falcon 2000
and Falcon 2000EX airplanes);
• 2006–0149 (for Model MystereFalcon 50, Mystere-Falcon 900, and
Falcon 900EX airplanes); and
• 2006–0156 (for Model Fan Jet
Falcon, Mystere-Falcon 20, and
Mystere-Falcon 200 airplanes).
The EASA airworthiness directives
´ ´
supersede the Direction Generale de
l’Aviation Civile (DGAC) airworthiness
directives referenced in the existing AD
for accomplishing the required actions.
The DGAC airworthiness directives
require repeating the operational test
and inspection at intervals not to exceed
13 months; the EASA airworthiness
directives extend that interval to 24
months, and EASA airworthiness
directive 2006–0148 adds Model Falcon
2000EX to the applicability specified in
the existing AD.
FAA’s Determination and Requirements
of the Proposed AD
These airplanes are manufactured in
France and are 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 EASA has kept the FAA informed of
the situation described above. We have
examined the EASA’s findings,
PO 00000
Frm 00012
Fmt 4702
Sfmt 4702
45959
evaluated all pertinent information, and
determined that AD action is necessary
for airplanes of this type design that are
certificated for operation in the United
States.
This proposed AD would supersede
AD 2000–12–15 and would retain the
requirements of the existing AD. This
proposed AD would expand the
applicability of the existing AD and
extend the repetitive test and inspection
interval for all airplanes.
Explanation of Changes Made to
Existing AD
This proposed AD would retain all
requirements of AD 2000–12–15. Since
that AD was issued, the AD format has
been revised, and certain paragraphs
have been rearranged. As a result, the
corresponding paragraph identifiers
have changed in this proposed AD, as
listed in the following table:
REVISED PARAGRAPH IDENTIFIERS

2000–12–15
Paragraph (a) ............
Paragraph (b) ............
Paragraph (c) ............
Corresponding
requirement in this
proposed AD
Paragraph (f).
Paragraph (h).
Paragraph (i).
On July 10, 2002, the FAA issued a
new version of 14 CFR part 39 (67 FR
47997, July 22, 2002), which governs the
FAA’s airworthiness directives system.
The regulation now includes material
that relates to altered products, special
flight permits, and alternative methods
of compliance. However, for clarity and
consistency in this proposed AD, we
have retained the language of the
existing AD regarding that material.
We have clarified the inspection
requirement contained in the proposed
AD. Whereas the existing AD specifies
a detailed visual inspection, we have
revised this proposed AD to clarify that
our intent is to require a detailed
inspection. Additionally, a note has
been added to the proposed AD to
define that inspection.
We have revised the existing AD to
clarify the appropriate procedure for
notifying the principal inspector before
using any approved alternative method
of compliance (AMOC) on any airplane
to which the AMOC applies.
We have revised the applicability of
the existing AD to identify model
designations as published in the most
recent type certificate data sheet for the
affected models.
After the existing AD was issued, we
reviewed the figures we have used over
the past several years to calculate AD
costs to operators. To account for
various inflationary costs in the airline
E:\FR\FM\16AUP1.SGM
16AUP1
45960
Federal Register / Vol. 72, No. 158 / Thursday, August 16, 2007 / Proposed Rules
industry, we find it necessary to
increase the labor rate used in these
calculations from $60 per work hour to
$80 per work hour. The cost impact
information, below, reflects this
increase in the specified hourly labor
rate.
Costs of Compliance
This proposed AD would affect about
870 airplanes of U.S. registry.
The actions that are required by AD
2000–12–15 and retained in this
proposed AD take about 1 work hour
per airplane, at an average labor rate of
$80 per work hour. Based on these
figures, the estimated cost of the
currently required actions is $80 per
airplane, per test and inspection cycle.
The new proposed actions would take
about 1 work hour per airplane, at an
average labor rate of $80 per work hour.
Based on these figures, the estimated
cost of the new actions specified in this
proposed AD for U.S. operators is
$69,600, or $80 per airplane, per test
and inspection cycle.
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.
rwilkins on PROD1PC63 with PROPOSALS
Regulatory Findings
We have 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 the proposed regulation:
1. Is not a ‘‘significant regulatory
action’’ under Executive Order 12866;
VerDate Aug<31>2005
17:19 Aug 15, 2007
Jkt 211001
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. See the ADDRESSES section
for a location to examine the regulatory
evaluation.

AGENCY:
SUMMARY: The FAA proposes to adopt a
new airworthiness directive (AD) for
certain Boeing Model 757–200, –200CB,
and –300 series airplanes. This
proposed AD would require repetitive
inspections for cracks of the intercostal
tee clips and attachment fasteners at the
number 3 and number 4 doorstops of
the passenger door cutouts, or repetitive
inspections for cracks of the intercostal
tee clips; and related investigative/
corrective actions if necessary. This
proposed AD also provides an optional
terminating action for the repetitive
inspections. This proposed AD results
from reports of cracked intercostal tee
clips at the number 3 and number 4
doorstops of the passenger door cutouts.
We are proposing this AD to detect and
correct cracking of the tee clips, which
could result in additional stress on the
adjacent tee clips, surrounding
intercostals, edge frame, door structure
and doorstops. This additional stress
could cause further cracking or breaking
of the tee clips, which could result in
failure of the door to seal and
consequent rapid decompression of the
airplane.
DATES: We must receive comments on
this proposed AD by October 1, 2007.

Discussion
We have received eight reports
indicating that cracked intercostal tee
clips were found at the number 3 and
number 4 doorstops of the passenger
door cutouts on certain Boeing Model
757–200, –200CB, and –300 series
airplanes. These cracks were found
during normal maintenance checks on
passenger doorway number 4, at the aft
edge frame of body station 1681.8 on the
left and right sides. On two airplanes,
cracks were found on the intercostal tee
clips at both the number 3 and number
4 doorstops. The cracks occurred in the
radius area of the tee clip, between the
horizontal and vertical flange. The
number of flight cycles for these
airplanes was between 22,700 and
25,000. The cracks in the tee clips are
attributed to a preload of the tee clip;
continued flight with cracks in the tee
clips can place additional stress on the
adjacent tee clips, surrounding
intercostals, edge frame, door structure
and doorstops. This additional stress, if
not corrected, could cause further
cracking or breaking of the tee clips,
which could result in failure of the door
to seal and consequent rapid
decompression of the airplane.
Relevant Service Information
We have reviewed Boeing Alert
Service Bulletin 757–53A0093, dated
November 8, 2006. The service bulletin
describes procedures for repetitive
detailed inspections with a borescope
for cracks of the intercostal tee clips; or
repetitive detailed inspections for cracks
of the intercostal tee clips and
attachment fasteners at the number 3
and number 4 doorstops of the
passenger door cutouts after the galley/
lavatory has been removed; and related
investigative and corrective actions if
necessary. The related investigative and
corrective actions include the following:

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: The FAA proposes to supersede an existing airworthiness
directive (AD) that applies to all Dassault Model Falcon 2000, Mystere-
Falcon 900, Falcon 900EX, Fan Jet Falcon, Mystere-Falcon 50, Mystere-
Falcon 20, Mystere-Falcon 200, and Falcon 10 series airplanes. The
existing AD currently requires repetitive tests and inspections to
detect discrepancies of the overwing emergency exit, and corrective
action if necessary. This proposed AD would expand the applicability of
the existing AD and extend the repetitive test and inspection interval
for all airplanes. This proposed AD results from reports of incorrect
operation of the overwing emergency exit due to interference between
the emergency exit and the interior accommodation. We are proposing
this AD to prevent failure of the overwing emergency exits to open, and
consequent injury to passengers or crew members during an emergency
evacuation.
DATES: We must receive comments on this proposed AD by September 17,
2007.

Discussion
On June 9, 2000, we issued AD 2000-12-15, amendment 39-11793 (65 FR
37480, June 15, 2000), for all Dassault Model Falcon 2000, Mystere-
Falcon 900, Falcon 900EX, Fan Jet Falcon, Mystere-Falcon 50, Mystere-
Falcon 20, Mystere-Falcon 200, and Falcon 10 series airplanes. That AD
requires repetitive tests and inspections to detect discrepancies of
the overwing emergency exit, and corrective action if necessary. That
AD resulted from issuance of mandatory continuing airworthiness
information by a foreign civil airworthiness authority. We issued that
AD to prevent failure of the overwing emergency exits to open, and
consequent injury to passengers or crew members during an emergency
evacuation.
Actions Since Existing AD Was Issued
Since we issued AD 2000-12-15, the European Aviation Safety Agency
(EASA), which is the Technical Agent for the Member States of the
European Community, has issued the following EASA airworthiness
directives, all dated June 7, 2006:
2006-0147 (for Model Falcon 10 airplanes);
2006-0148 (for Model Falcon 2000 and Falcon 2000EX
airplanes);
2006-0149 (for Model Mystere-Falcon 50, Mystere-Falcon
900, and Falcon 900EX airplanes); and
2006-0156 (for Model Fan Jet Falcon, Mystere-Falcon 20,
and Mystere-Falcon 200 airplanes).
The EASA airworthiness directives supersede the Direction
G[eacute]n[eacute]rale de l'Aviation Civile (DGAC) airworthiness
directives referenced in the existing AD for accomplishing the required
actions. The DGAC airworthiness directives require repeating the
operational test and inspection at intervals not to exceed 13 months;
the EASA airworthiness directives extend that interval to 24 months,
and EASA airworthiness directive 2006-0148 adds Model Falcon 2000EX to
the applicability specified in the existing AD.
FAA's Determination and Requirements of the Proposed AD
These airplanes are manufactured in France and are 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 EASA has kept the FAA informed
of the situation described above. We have examined the EASA's findings,
evaluated all pertinent information, and determined that AD action is
necessary for airplanes of this type design that are certificated for
operation in the United States.
This proposed AD would supersede AD 2000-12-15 and would retain the
requirements of the existing AD. This proposed AD would expand the
applicability of the existing AD and extend the repetitive test and
inspection interval for all airplanes.
Explanation of Changes Made to Existing AD
This proposed AD would retain all requirements of AD 2000-12-15.
Since that AD was issued, the AD format has been revised, and certain
paragraphs have been rearranged. As a result, the corresponding
paragraph identifiers have changed in this proposed AD, as listed in
the following table:
Revised Paragraph Identifiers
------------------------------------------------------------------------
Corresponding requirement
Requirement in AD 2000-12-15 in this proposed AD
------------------------------------------------------------------------
Paragraph (a)............................. Paragraph (f).
Paragraph (b)............................. Paragraph (h).
Paragraph (c)............................. Paragraph (i).
------------------------------------------------------------------------
On July 10, 2002, the FAA issued a new version of 14 CFR part 39
(67 FR 47997, July 22, 2002), which governs the FAA's airworthiness
directives system. The regulation now includes material that relates to
altered products, special flight permits, and alternative methods of
compliance. However, for clarity and consistency in this proposed AD,
we have retained the language of the existing AD regarding that
material.
We have clarified the inspection requirement contained in the
proposed AD. Whereas the existing AD specifies a detailed visual
inspection, we have revised this proposed AD to clarify that our intent
is to require a detailed inspection. Additionally, a note has been
added to the proposed AD to define that inspection.
We have revised the existing AD to clarify the appropriate
procedure for notifying the principal inspector before using any
approved alternative method of compliance (AMOC) on any airplane to
which the AMOC applies.
We have revised the applicability of the existing AD to identify
model designations as published in the most recent type certificate
data sheet for the affected models.
After the existing AD was issued, we reviewed the figures we have
used over the past several years to calculate AD costs to operators. To
account for various inflationary costs in the airline
[[Page 45960]]
industry, we find it necessary to increase the labor rate used in these
calculations from $60 per work hour to $80 per work hour. The cost
impact information, below, reflects this increase in the specified
hourly labor rate.
Costs of Compliance
This proposed AD would affect about 870 airplanes of U.S. registry.
The actions that are required by AD 2000-12-15 and retained in this
proposed AD take about 1 work hour per airplane, at an average labor
rate of $80 per work hour. Based on these figures, the estimated cost
of the currently required actions is $80 per airplane, per test and
inspection cycle.
The new proposed actions would take about 1 work hour per airplane,
at an average labor rate of $80 per work hour. Based on these figures,
the estimated cost of the new actions specified in this proposed AD for
U.S. operators is $69,600, or $80 per airplane, per test and inspection
cycle.
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 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 the 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. See the
ADDRESSES section for a location to examine the regulatory evaluation.
List of Subjects in 14 CFR Part 39
