[Docket No. FAA-2006-26232; Directorate Identifier 2006-CE-62-AD]
RIN 2120-AA64
Airworthiness Directives; EADS SOCATA Model TBM 700 Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
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) 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 report of a master cylinder yoke failure. 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 December 28,
2006.

SUPPLEMENTARY INFORMATION:
Streamlined Issuance of AD
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 follow all FAA AD
issuance processes to meet legal, economic, Administrative Procedure
Act, and Federal Register requirements. We also continue to meet our
technical decision-making responsibilities to identify and correct
unsafe conditions on U.S.-certificated products.
This proposed AD references the MCAI and related service
information that we considered in forming the engineering basis to
correct the unsafe condition. The proposed AD contains text copied from
the MCAI and for this reason might not follow our plain language
principles.
Comments Invited
We invite you to send any written relevant data, views, or
arguments about this proposed AD. Send your comments to an address
listed under the
[[Page 68763]]
ADDRESSES section. Include ``Docket No. FAA-2006-26232; Directorate
Identifier 2006-CE-62-AD'' at the beginning of your comments. We
specifically invite comments on the overall regulatory, economic,
environmental, and energy aspects of this proposed AD. We will consider
all comments received by the closing date and may amend this proposed
AD because of those comments.
We will post all comments we receive, without change, to http://dms.dot.gov
, including any personal information you provide. We will
also post a report summarizing each substantive verbal contact we
receive about this proposed AD.
Discussion
The European Aviation Safety Agency (EASA), which is the Technical
Agent for the European Community, has issued AD No.: 2006-0189, dated
July 4, 2006 (referred to after this as ``the MCAI''), to correct an
unsafe condition for the specified products. The MCAI states there was
a report of a master cylinder yoke failure. The AD requirements are to
detect defective yokes on aircraft and replace them. The aim of this AD
is to ensure that normal braking is available at any time to prevent
possible runway excursions in the event of failure of the master
cylinder yoke. You may obtain further information by examining the MCAI
in the AD docket.
Relevant Service Information
EADS SOCATA has issued TBM Aircraft Mandatory Service Bulletin SB
70-136, ATA No. 32, dated December 2005. 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 This 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 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
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 270 products of U.S. registry. We also estimate that
it would take about 1.5 work-hours per product to comply with the
proposed AD. The average labor rate is $80 per work-hour. Required
parts would cost about $600 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 $194,400, or $720
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:
EADS SOCATA: Docket No. FAA-2006-26232; Directorate Identifier 2006-
CE-62-AD
Comments Due Date
(a) We must receive comments by December 28, 2006.
Affected ADs
(b) None.
Applicability
(c) This AD applies to SOCATA Model TBM 700 airplanes, all
serial numbers, certificated in any category.
Reason
(d) The mandatory continuing airworthiness information (MCAI)
states there was a report of a master cylinder yoke failure. The AD
requirements are to detect defective yokes on aircraft and replace
them. The aim of this AD is to ensure that normal braking is
available at any time to prevent possible runway excursions in the
event of failure of the master cylinder yoke.
[[Page 68764]]
Actions and Compliance
(e) Unless already done, do the following actions.
(1) For the serial numbers indicated below, within the next 100
hours time-in-service or 12 months after the effective date of this
AD, whichever occurs first, do the following actions, unless already
done:
(i) For airplane serial numbers 269 and 339 and up, check the
aircraft records to determine whether cylinder yoke part number
ZOO.N7134732200 or the yokes in master cylinder assembly part number
ZOO.N6068757280 (left hand side) and ZOO.N6068757281 (right hand
side) have been replaced. This check can be done by an owner/
operator holding at least a private pilot certificate as authorized
by section 43.7 of the Federal Aviation Regulations (14 CFR 43.7).
(A) If you can positively identify that master cylinder yoke
part number ZOO.N7134732200 or the yokes in master cylinder assembly
part number ZOO.N6068757280 (left hand side) and ZOO.N6068757281
(right hand side) have been replaced, then you must comply with
paragraph (e)(1)(ii) of this AD.
(B) If you can positively identify that master cylinder yoke
part number ZOO.N7134732200 or the yokes in master cylinder assembly
part number ZOO.N6068757280 (left hand side) and ZOO.N6068757281
(right hand side) have not been replaced, then make an entry in the
aircraft records showing compliance with this AD per section 43.9 of
the Federal Aviation Regulations (14 CFR 43.9).
(ii) For all airplane serial numbers, unless the action is shown
not to apply per paragraph (e)(1)(i)(B) of this AD, inspect for
misalignment of the master cylinder yokes from their threaded pins,
as instructed in the EADS SOCATA TBM Aircraft Mandatory Service
Bulletin SB 70-136, ATA No. 32, dated December 2005, accomplishment
instructions paragraph.
(A) If a yoke is found satisfactory, proceed to its re-
installation on aircraft.
(B) If a yoke is found defective, prior to further flight,
discard the yoke and install a new part number T700A324004810000 (or
FAA-approved equivalent part number) yoke in accordance with EADS
SOCATA TBM Aircraft Mandatory Service Bulletin SB 70-136, ATA No.
32, dated December 2005.
(2) For all airplane serial numbers, as of the effective date of
this AD, do not install part number ZOO.N7134732200 yokes or yokes
in master cylinder assembly part number ZOO.N6068757280 (left hand
side) and ZOO.N6068757281 (right hand side), unless EADS SOCATA TBM
Aircraft Mandatory Service Bulletin SB 70-136, ATA No. 32, dated
December 2005, is complied with.
FAA AD Differences
Note: This AD differs from the MCAI and/or service information
as follows:
(1) It does not allow interim use of yokes found defective
during inspection. FAA policy is to replace defective parts on
critical systems.
(2) It applies to all serial numbers. This will assure that, if
any of the airplanes had the affected part number yokes installed
after delivery of the airplane, the unsafe condition is still
addressed. It also will assure that any of the affected part number
yokes are inspected per the AD and service bulletin before future
installation of these parts.
Other FAA AD Provisions
(f) The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager,
Standards Staff, FAA, ATTN: Doug Rudolph, Aerospace Engineer, FAA,
Small Airplane Directorate, 901 Locust, Room 301, Kansas City,
Missouri 64106; telephone: (816) 329-4059; fax: (816) 329-4090, has
the authority to approve AMOCs for this AD, if requested using the
procedures found in 14 CFR 39.19.
(2) Airworthy Product: For any requirement in this AD to obtain
corrective actions from a manufacturer or other source, use these
actions if they are FAA-approved. Corrective actions are considered
FAA-approved if they are approved by the State of Design Authority
(or their delegated agent). You are required to assure the product
is airworthy before it is returned to service.
(3) Reporting Requirements: For any reporting requirement in
this AD, under the provisions of the Paperwork Reduction Act (44
U.S.C. 3501 et.seq.), the Office of Management and Budget (OMB) has
approved the information collection requirements and has assigned
OMB Control Number 2120-0056.
