AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Notice of proposed rulemaking (NPRM).

SUMMARY:

This document proposes to adopt a new airworthiness directive (AD) that would apply to all SOCATA—Groupe AEROSPATIALE (Socata) Model TBM 700 airplanes. This proposed AD would require you to perform a test on the flight control system and adjust the control roll stop if jamming occurs during the test. This proposed AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for France. The actions specified by this proposed AD are intended to prevent the flight control wheels from traveling beyond normal roll control limits, which could result in the control wheel becoming jammed. Such a condition could lead to reduced or loss of control of the airplane.

DATES:

The Federal Aviation Administration (FAA) must receive any comments on this proposed rule on or before August 14, 2002.

Discussion

What Events Have Caused This Proposed AD?

The Direction Générale de l'Aviation Civile (DGAC), which is the airworthiness authority for France, recently notified FAA that an unsafe condition may exist on all Socata Model TBM 700 airplanes. The DGAC reports that, during a ground test of the flight control system on one of the affected airplanes, the pilot control wheel became jammed when performing dual actions (e.g., full up and full left) because the control wheel was turned beyond normal roll control travel limits. This was a result of a misadjustment of the roll control.

What Are the Consequences if the Condition Is Not Corrected?

If this condition is not corrected, it could result in the flight control wheels traveling beyond normal roll control limits, which could result in the control wheel becoming jammed. This could lead to reduced or loss of control of the airplane.

Is There Service Information That Applies to This Subject?

Socata has issued Service Bulletin SB 70-095 27, dated November 2001.

What Are the Provisions of This Service Information?

The service bulletin includes procedures for:

—Inspecting the flight control system to determine if jamming occurs; and

—Adjusting the roll control stop to correct this condition.

What Action Did the DGAC Take?

The DGAC classified this service bulletin as mandatory and issued French AD 2001-582(A), dated November 28, 2001, in order to ensure the continued airworthiness of these airplanes in France. Start Printed Page 46131

Was This in Accordance With the Bilateral Airworthiness Agreement?

This airplane model is manufactured in France and are type certificated for operation in the United States under the provisions of section 21.29 of the Federal Aviation Regulations (14 CFR 21.29) and the applicable bilateral airworthiness agreement.

Pursuant to this bilateral airworthiness agreement, the DGAC has kept FAA informed of the situation described above.

The FAA's Determination and an Explanation of the Provisions of This Proposed AD

What Has FAA Decided?

The FAA has examined the findings of the DGAC; reviewed all available information, including the service information referenced above; and determined that:

—The unsafe condition referenced in this document exists or could develop on other Socata Model TBM 700 airplanes of the same type design that are on the U.S. registry;

—The actions specified in the previously-referenced service information should be accomplished on the affected airplanes; and

—AD action should be taken in order to correct this unsafe condition.

What Would This Proposed AD Require?

This proposed AD would require you to incorporate the actions in the previously-referenced service bulletin.

What Are the Differences Between This Proposed AD, the Service Information, and the DGAC AD?

The DGAC AD requires inspection, and, if necessary, adjustment prior to further flight after the effective date of the AD. We propose a requirement that you inspect, and, if necessary, adjust within 100 hours time-in-service (TIS) after the effective date of this proposed AD.

We do not have justification to require this action prior to further flight. We use compliance times such as this when we have identified an urgent safety of flight situation. We believe that 100 hours TIS will give the owners or operators of the affected airplanes enough time to have the proposed actions accomplished without compromising the safety of the airplanes.

Cost Impact

How Many Airplanes Would This Proposed AD Impact?

We estimate that this proposed AD affects 133 airplanes in the U.S. registry.

What Would Be the Cost Impact of This Proposed AD on Owners/Operators of the Affected Airplanes?

We estimate the following costs to accomplish the proposed initial inspection:

Labor costParts costTotal cost per airplaneTotal cost on U.S. operators
1 workhour × $60 per hour = $60None$60$60 × 133 = $7,980.

We estimate the following costs to accomplish any necessary modification that would be required based on the results of the proposed inspection. We have no way of determining the number of airplanes that may need such modification:

Labor costParts costTotal cost per airplane
3 workhours × $60 per hour=$180None$180

Regulatory Impact

Would This Proposed AD Impact Various Entities?

The regulations proposed herein 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. Therefore, it is determined that this proposed rule would not have federalism implications under Executive Order 13132.

Would This Proposed AD Involve a Significant Rule or Regulatory Action?

For the reasons discussed above, I certify that this proposed action (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) if promulgated, 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. A copy of the draft regulatory evaluation prepared for this action has been placed in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption ADDRESSES.
