Appendix I
Section I:
The first moving average of lift cycles per
hour TIS.
The first moving average calculation is
performed on the IFWU assembly when the
external lift component history card record
reflects that the IFWU assembly has reached
its first 250 hours TIS. To perform the
calculation, divide the total number of lift
cycles performed during the first 250 hours
TIS by 250. The result will be the first
moving average calculation of lift cycles per
hour TIS.
Section II:
Subsequent moving average of lift cycles
per hour TIS.
Subsequent moving average calculations
are performed on the IFWU assembly at
intervals of 50 hour TIS intervals after the
first moving average calculation. Subtract the
total number of lift cycles performed during
the first 50-hour TIS interval used in the
previous moving average calculation from the
total number of lift cycles performed on the
IFWU assembly during the previous 300
hours TIS. Divide this result by 250. The
result will be the next or subsequent moving
average calculation of lift cycles per hour
TIS.
Section III:
Sample calculation for subsequent 50 hour
TIS intervals.
Assume the total number of lift cycles for
the first 50 hour TIS interval used in the
previous moving average calculation = 450
lift cycles and the total number of lift cycles
for the previous 300 hours TIS = 2700 lift
cycles. The subsequent moving average of lift
cycles per hour TIS = (2700¥450) divided by
250 = 9 lift cycles per hour TIS.

The FAA is implementing a new
process for streamlining the issuance of
ADs related to MCAI. The streamlined
process will allow us to adopt MCAI
safety requirements in a more efficient
manner and will reduce safety risks to
the public. This process continues to

Discussion
The European Aviation Safety
Agency, which is the airworthiness
authority for the European Union, has
issued Emergency AD No. 2006–0226–E,
Issue date: July 21, 2006 (referred to
after this as ‘‘the MCAI’’), to correct an
unsafe condition for the specified
products. The MCAI states that the
aircraft manufacturer has identified an
unsafe condition resulting from an
incomplete thermal treatment done on
three hinge pin batches lowering their
mechanical properties with a high risk
of deformation under service loads. If
not corrected, the nose landing gear
(NLG) hinge pin may rupture and cause
an uncommanded NLG retraction.
The MCAI requires that you first
identify the concerned NLG, and
second, detect the defective hinge pins
on aircraft or on shelves and replace
them with new ones. You may obtain
further information by examining the
MCAI in the docket.

Relevant Service Information
EADS SOCATA has issued TBM
Aircraft Alert Service Bulletin SB 70–
147, ATA No. 32, dated July 2006. The
actions described in this service
information are intended to correct the
unsafe condition identified in the
MCAI.

FAA’s Determination and Requirements
of the 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 this State of
Design Authority, they have notified us
of the unsafe condition described in the
MCAI and service information
referenced above. We are proposing this
AD because we evaluated all
information and determined the unsafe
condition exists and is likely to exist or
develop on other products of the same
type design.
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 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.
Differences Between the Proposed 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 a U.S.
court of law. 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
described in a separate paragraph of the
proposed AD. These proposed
requirements, if ultimately adopted, will
take precedence over the actions copied
from the MCAI.
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.
Costs of Compliance
Based on the service information, we
estimate that this proposed AD would
affect about 256 products of U.S.
registry. We also estimate that it would
take about 2 work-hours per product to
do the action and that the average labor
rate is $80 per work-hour. Required
parts would cost about $1,025 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
$303,360, or $1,185 per product.
Authority for This Rulemaking
Title 49 of the United States Code
specifies 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.

120 survey would be conducted once
every five years beginning with fiscal
year 2006.
The proposed BE–120 survey is
intended to cover the universe of
selected services transactions and
transactions in intangible assets with
foreign persons. In nonbenchmark years,
universe estimates covering these
transactions would be derived from the
sample data reported on BEA’s followon quarterly survey, by extrapolating
forward the universe data collected on
the BE–120 benchmark survey.

Discussion
The European Aviation Safety Agency, which is the airworthiness
authority for the European Union, has issued Emergency AD No. 2006-
0226-E, Issue date: July 21, 2006 (referred to after this as ``the
MCAI''), to correct an unsafe condition for the specified products. The
MCAI states that the aircraft manufacturer has identified an unsafe
condition resulting from an incomplete thermal treatment done on three
hinge pin batches lowering their mechanical properties with a high risk
of deformation under service loads. If not corrected, the nose landing
gear (NLG) hinge pin may rupture and cause an uncommanded NLG
retraction.
The MCAI requires that you first identify the concerned NLG, and
second, detect the defective hinge pins on aircraft or on shelves and
replace them with new ones. You may obtain further information by
examining the MCAI in the docket.
Relevant Service Information
EADS SOCATA has issued TBM Aircraft Alert Service Bulletin SB 70-
147, ATA No. 32, dated July 2006. The actions described in this service
information are intended to correct the unsafe condition identified in
the MCAI.
FAA's Determination and Requirements of the 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 this State of Design Authority, they
have notified us of the unsafe condition described in the MCAI and
service information referenced above. We are proposing this AD because
we evaluated all information and determined the unsafe condition exists
and is likely to exist or develop on other products of the same type
design.
Differences Between the Proposed 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 a U.S. court of
law. 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
described in a separate paragraph of the proposed AD. These proposed
requirements, if ultimately adopted, will take precedence over the
actions copied from the MCAI.
Costs of Compliance
Based on the service information, we estimate that this proposed AD
would affect about 256 products of U.S. registry. We also estimate that
it would take about 2 work-hours per product to do the action and that
the average labor rate is $80 per work-hour. Required parts would cost
about $1,025 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 $303,360, or $1,185 per product.
Authority for This Rulemaking
Title 49 of the United States Code specifies 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 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.
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 Federal Aviation Administration 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:
EADS SOCATA: FAA-2006-25581; Directorate Identifier 2006-CE-41-AD
[[Page 54448]]
Comments Due Date
(a) We must receive comments on this proposed airworthiness
directive (AD) by October 16, 2006.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Model TBM 700 airplanes fitted with
nose landing gear (NLG) part number (P/N) 21130-001-02 with serial
numbers (S/N) B168 through B173 and S/N EUR 174 through EUR 239,
that are certificated in any U.S. category.
Reason
(d) The mandatory continuing airworthiness information (MCAI)
states that the aircraft manufacturer has identified an unsafe
condition resulting from an incomplete thermal treatment done on
three hinge pin batches lowering their mechanical properties with a
high risk of deformation under service loads. If not corrected, the
NLG hinge pin may rupture and cause an uncommanded NLG retraction.
Actions and Compliance
(e) Within 30 days after the effective date of this AD, unless
already done, do the following except as stated in paragraph (f)
below.
(1) Verify the NLG serial number to determine its eligibility to
this AD. If the NLG S/N is not listed in the applicability paragraph
of this AD, no further action is required.
(2) For airplanes with the applicable NLG S/N, apply the
operational procedure as indicated in paragraph A of the
accomplishment instructions of EADS SOCATA TBM Aircraft Alert
Service Bulletin SB 70-147, ATA No. 32, dated July 2006. This can be
done by inserting into the airplane flight manual, the EADS SOCATA
TBM Aircraft Alert Service Bulletin SB 70-147, ATA No. 32, dated
July 2006.
(3) Identify the pin batch number as instructed in paragraph B
of the accomplishment instructions of EADS SOCATA TBM Aircraft Alert
Service Bulletin SB 70-147, ATA No. 32, dated July 2006. For
airplanes with the correct pin batch numbers, no further action is
required. Return the airplane to service as instructed in EADS
SOCATA TBM Aircraft Alert Service Bulletin SB 70-147, ATA No. 32,
dated July 2006.
(4) For airplanes with pins from the defective pin batch numbers
or for which the batch number is unreadable, do all the actions as
instructed in paragraphs B 5), C, and D of the accomplishment
instructions of EADS SOCATA TBM Aircraft Alert Service Bulletin SB
70-147, ATA No. 32, dated July 2006.
(5) As of the effective date of this AD, no person shall install
on any EADS SOCATA Model TBM 700 airplane, any NLG actuator hinge
pins coming from the three defective batches identified as EUR BC
21344-000-01, EUR BD 21344-000-01, and EUR BF 21344-000-01 on NLG
part number 21130-001-02.
FAA AD Differences
(f) None.
