Airworthiness Directives; 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) originated 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 TBM 700 operator reported a case of elevator trim tab actuator 
jamming once the trim tab arrived to stop.
    The investigations conducted by the trim tab actuator 
manufacturer have shown that there was a discrepancy with PRECILEC 
manufacturing process of elevator trim tab actuator which caused 
this event. It has been determined as well that this discrepancy is 
limited to a batch of Serial Numbers (S/N).
    If not detected and corrected, a jammed trim tab could lead to 
unusual control forces, resulting in lower controllability, 
particularly if combined with adverse flight conditions at landing.

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 July 11, 2011.

Discussion

    The European Aviation Safety Agency (EASA), which is the Technical 
Agent for the Member States of the European Community, has issued EASA 
AD No.: 2011-0060, dated March 29, 2011 (Correction: March 30, 2011) 
(referred to after this as ``the MCAI''), to correct an unsafe 
condition for the specified products. The MCAI states:

    A TBM 700 operator reported a case of elevator trim tab actuator 
jamming once the trim tab arrived to stop.
    The investigations conducted by the trim tab actuator 
manufacturer have shown that there was a discrepancy with PRECILEC 
manufacturing process of elevator trim tab actuator which caused 
this event. It has been determined as well that this discrepancy is 
limited to a batch of Serial Numbers (S/N).
    If not detected and corrected, a jammed trim tab could lead to 
unusual control forces, resulting in lower controllability, 
particularly if combined with adverse flight conditions at landing.
    For the reasons described above, this AD requires the inspection 
of the elevators trim tab actuator P/N 6071017251 for identification 
of S/N and, in case of findings, the replacement of the affected 
ones with serviceable units.

You may obtain further information by examining the MCAI in the AD 
docket.

Relevant Service Information

    DAHER-SOCATA has issued Mandatory Service Bulletin SB 70-190-27, 
dated January 2011. 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 
highlighted in a NOTE within the proposed AD.

Costs of Compliance

    We estimate that this proposed AD will affect 377 products of U.S. 
registry. We also estimate that it would take about 1 work-hour per 
product to comply with the basic requirements of this proposed AD. The 
average labor rate is $85 per work-hour. Required parts would cost 
about $0 per product.
    Based on these figures, we estimate the cost of the proposed AD on 
U.S. operators to be $32,045, or $85 per product.
    In addition, we estimate that any necessary follow-on actions would 
take about 7 work-hours and require parts costing $0, for a cost of 
$595 per product. We have no way of determining the number of products 
that may need these actions.
    According to the manufacturer, some of the costs of this proposed 
AD may be covered under warranty, thereby reducing the cost impact on 
affected individuals. We do not control warranty coverage for affected 
individuals. As a result, we have included all costs in our cost 
estimate.

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, Incorporation by 
reference, 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:

SOCATA: Docket No. FAA-2011-0530; Directorate Identifier 2011-CE-
012-AD.

Comments Due Date

    (a) We must receive comments by July 11, 2011.

Affected ADs

    (b) None.

Applicability

    (c) This AD applies to SOCATA Model TBM 700 airplanes, serial 
numbers 1 through 530, certificated in any category.

Subject

    (d) Air Transport Association of America (ATA) Code 27: Flight 
Controls.

Reason

    (e) The mandatory continuing airworthiness information (MCAI) 
states:

    A TBM 700 operator reported a case of elevator trim tab actuator 
jamming once the trim tab arrived to stop.
    The investigations conducted by the trim tab actuator 
manufacturer have shown that there was a discrepancy with PRECILEC 
manufacturing process of elevator trim tab actuator which caused 
this event. It has been determined as well that this discrepancy is 
limited to a batch of Serial Numbers (S/N).
    If not detected and corrected, a jammed trim tab could lead to 
unusual control forces, resulting in lower controllability, 
particularly if combined with adverse flight conditions at landing.
    For the reasons described above, this AD requires the inspection 
of the elevators trim tab actuator P/N 6071017251 for identification 
of S/N and, in case of findings, the replacement of the affected 
ones with serviceable units.

Actions and Compliance

    (f) Unless already done, do the following actions:

    (1) Within 12 months after the effective date of this AD, 
identify the serial number (S/N) of Left Hand and Right Hand 
PRECILEC elevator trim tab actuators following DAHER-SOCATA 
Mandatory Service Bulletin SB 70-190-27, dated January 2011.
    (2) If, as a result of the inspection required by paragraph 
(f)(1) of this AD you find any affected elevator trim tab actuator 
as listed in DAHER-SOCATA Mandatory Service Bulletin SB 70-190-27, 
dated January 2011, installed on an airplane, before further flight, 
replace it with a serviceable part following DAHER-SOCATA Mandatory 
Service Bulletin SB 70-190-27, dated January 2011.
    (3) After the effective date of this AD, do not install on an 
airplane any PRECILEC elevator trim tab actuator part number 
6071017251 with an S/N listed in DAHER-SOCATA Mandatory Service 
Bulletin SB 70-190-27, dated January 2011, unless it has been 
repaired in accordance with DAHER-SOCATA Mandatory Service Bulletin 
SB 70-190-27, dated January 2011.

    Note 1: Trim tab actuators repaired by a service center are 
identified with screw green colored locking varnish as shown in 
figure 2 of DAHER-SOCATA Mandatory Service Bulletin SB 70-190-27, 
dated January 2011.

FAA AD Differences

    Note 2: This AD differs from the MCAI and/or service information 
as follows: No differences.

Other FAA AD Provisions

    (g) The following provisions also apply to this AD:
    (1) Alternative Methods of Compliance (AMOCs): The Manager,
