Airworthiness Directives; EADS SOCATA Model TBM 700 Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are superseding an existing airworthiness directive (AD)
for the products listed above. This AD results from mandatory
continuing airworthiness information (MCAI) issued 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:
A rupture of the alternator and vapour cycle cooling system
pulley drive assembly has reportedly been found. Such a failure
could lead to the loss of the alternator and vapour cycle cooling
systems and could also cause mechanical damage inside the powerplant
compartment.
We are issuing this AD to require actions to correct the unsafe
condition on these products.
DATES: This AD becomes effective September 23, 2008.
As of September 23, 2008, the Director of the Federal Register
approved the incorporation by reference of certain publications listed
in this AD.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that would apply to the specified products.
That NPRM was published in the Federal Register on June 9, 2008 (73 FR
32495), and proposed to supersede AD 2008-10-13, Amendment 39-15520 (73
FR 26318, May 9, 2008). That NPRM proposed to correct an unsafe
condition for the specified products. The MCAI states that:
A rupture of the alternator and vapour cycle cooling system
pulley drive assembly has reportedly been found. Such a failure
could lead to the loss of the alternator and vapour cycle cooling
systems and could also cause mechanical damage inside the powerplant
compartment.
To address this condition, AD 2008-0063-E had been published to
require a check of the pulley drive assembly for leakage and, as an
interim action, removal of the compressor drive belt from the
assembly, and adoption of a new operational procedure to keep the
air-conditioning system deactivated.
This AD retains the requirements of AD 2008-0063-E which is
superseded, introduces a mandatory terminating action which consists
in replacing the original pulley drive assembly by a new one of an
improved design--corresponding to the EADS SOCATA modification MOD
70-0231-21--that permits reinstallation of the compressor drive
belt.
Comments
We gave the public the opportunity to participate in developing
this AD. We received no comments on the NPRM or on the determination of
the cost to the public.
Conclusion
We reviewed the available data and determined that air safety and
the public interest require adopting the AD as proposed.
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 required 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 AD.
Costs of Compliance
We estimate that this AD will affect 21 products of U.S. registry.
We also estimate that it will take about 10 work-hours per product to
comply with basic requirements of this AD. The average labor rate is
$80 per work-hour. Required parts will cost about $2,912 per product.
Based on these figures, we estimate the cost of this AD to the U.S.
operators to be $77,952, or $3,712 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 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 this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866;
(2) Is not a ``significant rule'' under 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
[[Page 48287]]
under the criteria of the Regulatory Flexibility Act.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD Docket.
Examining the AD Docket
You may examine the AD docket on the Internet at http://
www.regulations.gov; or in person at the Docket Management Facility
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains the NPRM, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Office (telephone (800) 647-5527) is in the ADDRESSES
section. Comments will be available in the AD docket shortly after
receipt.

Accordingly, under the authority delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
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]
0
2. The FAA amends Sec. 39.13 by removing Amendment 39-15520 (73 FR
26318, May 9, 2008) and adding the following new AD:
2008-17-09 EADS SOCATA: Amendment 39-15647; Docket No. FAA-2008-
0627; Directorate Identifier 2008-CE-033-AD.
Effective Date
(a) This airworthiness directive (AD) becomes effective
September 23, 2008.
Affected ADs
(b) This AD supersedes AD 2008-10-13, Amendment 39-15520.
Applicability
(c) This AD applies to Models TBM 700 airplanes, serial numbers
434 through 455, certificated in any category.
Subject
(d) Air Transport Association of America (ATA) Code 24: Electric
Power.
Reason
(e) The mandatory continuing airworthiness information (MCAI)
states:
A rupture of the alternator and vapour cycle cooling system
pulley drive assembly has reportedly been found. Such a failure
could lead to the loss of the alternator and vapour cycle cooling
systems and could also cause mechanical damage inside the powerplant
compartment.
To address this condition, AD 2008-0063-E had been published to
require a check of the pulley drive assembly for leakage and, as an
interim action, removal of the compressor drive belt from the
assembly, and adoption of a new operational procedure to keep the
air-conditioning system deactivated.
This AD retains the requirements of AD 2008-0063-E which is
superseded, introduces a mandatory terminating action which consists
in replacing the original pulley drive assembly by a new one of an
improved design--corresponding to the EADS SOCATA modification MOD
70-0231-21--that permits reinstallation of the compressor drive
belt.
Actions and Compliance
(f) Unless already done, do the following before further flight
after May 9, 2008 (the compliance date retained from AD 2008-10-13):
(1) Position to ``OFF'' the air-conditioning ``AIR COND''
switch.
(2) Inspect for oil leakage in the pulley drive assembly by
following EADS SOCATA Service Bulletin (SB) No. 70-156 Amendment 1,
dated March 2008.
(i) If any leak is found, before further flight after the
inspection, replace the pulley drive assembly part number (P/N)
T700G215504900000 with P/N T700G215505710000 following EADS SOCATA
Service Bulletin (SB) No. 70-156 Amendment 1, dated March 2008.
(ii) If no leak is found, before further flight, remove the
compressor drive belt from the pulley drive assembly following
either EADS SOCATA Service Bulletin (SB) No. 70-156, original issue;
or EADS SOCATA Service Bulletin (SB) No. 70-156, Amendment 1; both
dated March 2008.
(3) The air-conditioning ``AIR COND'' switch must be in the
``OFF'' position and the compressor drive belt must remain removed
until the pulley drive assembly part number (P/N) T700G215504900000
is replaced with P/N T700G215505710000 following EADS SOCATA Service
Bulletin (SB) No. 70-156 Amendment 1, dated March 2008. This
replacement must be done before further flight if any leak is found
and may be done at any time as terminating action to this AD.
(g) Within the next 12 months after September 23, 2008 (the
effective date of this AD), unless already done, replace the pulley
drive assembly P/N T700G215504900000 with P/N T700G215505710000 and
reinstall the compressor drive belt, following EADS SOCATA Service
