# AGENCY:

Federal Aviation Administration (FAA), Department of Transportation (DOT).

# ACTION:

Final rule.

# SUMMARY:

We are adopting a new airworthiness directive (AD) for SOCATA Model TBM 700 airplanes. 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 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.

We are issuing this AD to require actions to correct the unsafe condition on these products.

# DATES:

This AD becomes effective September 19, 2011.

On September 19, 2011, 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 May 25, 2011 (76 FR 30295). That NPRM proposed 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.

## 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 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 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 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 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                           ( print page 50406)                        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 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.

## Adoption of the Amendment

Accordingly, under the authority delegated to me by the Administrator, the FAA amends 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.

§ 39.13 

2. The FAA amends § 39.13 by adding the following new AD: 

**2011-17-06 SOCATA:**                             Amendment 39-16770; Docket No. FAA-2011-0530; Directorate Identifier 2011-CE-012-AD.                        

## Effective Date

(a) This airworthiness directive (AD) becomes effective September 19, 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 September 19, 2011 (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 September 19, 2011 (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.
