Start Preamble

AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Final rule; request for comments.

SUMMARY:

This amendment adopts a new airworthiness directive (AD) that applies to certain Aeromot-Industria Mecanico Metalurgica Itda. (Aeromot) Models AMT-100 and AMT-200 powered sailplanes. This AD requires Start Printed Page 58916you to inspect (one-time) the main landing gear lever and elevator control rod for interference, warping, or incorrect gaps; and requires you to reconfigure or replace discrepant parts. This AD also requires you to report to the Federal Aviation Administration (FAA) any instances of interference, warping, or incorrect gaps. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Brazil. The actions specified by this AD are intended to detect and correct bending or warping in the main landing gear lever before it interferes with the elevator control rod. Such interference could result in the elevator control becoming jammed with consequent loss of control of the powered sailplane.

DATES:

This AD becomes effective on December 7, 2001.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulation as of December 7, 2001.

The FAA must receive any comments on this rule on or before December 26, 2001.

ADDRESSES:

Submit comments to FAA, Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 2001-CE-40-AD, 901 Locust, Room 506, Kansas City, Missouri 64106.

Discussion

What Events Have Caused This AD?

The Departamento de Aviacao Civil (DEAC), which is the airworthiness authority for Brazil, recently notified FAA that an unsafe condition may exist on certain Aeromot Models AMT-100 and AMT-200 powered sailplanes. The DEAC reports an instance where the elevator control jammed on one of the affected powered sailplanes. This occurred when the main landing gear lever interfered with the nut that attaches the rod end of the elevator control rod.

What Are the Consequences if the Condition Is Not Corrected?

Bending or warping in the main landing gear lever, if not detected and corrected before it interferes with the elevator control rod, could result in the elevator control becoming jammed with consequent loss of control of the powered sailplane.

Is There Service Information That Applies to This Subject?

Aeromot has issued Service Bulletin (S.B.) No. 200-27-078, Issue Date: September 18, 2001.

The service bulletin includes procedures for inspecting the main landing gear lever and elevator control rod for interference, warping, or incorrect gaps. It also specifies reconfiguring or replacing discrepant parts.

What Action Did the DEAC Take?

The DEAC classified this service bulletin as mandatory and issued Brazilian Emergency Airworthiness Directive (EAD) 2001-10-01, dated October 9, 2001, in order to ensure the continued airworthiness of these powered sailplanes in Brazil.

Was This in Accordance With the Bilateral Airworthiness Agreement?

These powered sailplane models are manufactured in Brazil 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 DEAC has kept us informed of the situation described above.

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

What Has FAA Decided?

The FAA has examined the findings of the DEAC; 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 Aeromot Models AMT-100 and AMT-200 powered sailplanes of the same type design that are registered for operation in the United States;

—The actions specified in the previously-referenced service information (as specified in this AD) should be accomplished on the affected powered sailplanes; and

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

What Does This AD Require?

This AD requires you to inspect (one-time) the main landing gear lever and elevator control rod for interference, warping, or incorrect gaps; and requires you to reconfigure or replace discrepant parts. This AD also requires you to report to the FAA any instances of interference, warping, or incorrect gaps.

We will use the information from the reports to determine whether additional rulemaking action is necessary (e.g., repetitive inspections).

In preparation of this rule, we contacted type clubs and aircraft operators to obtain technical information and information on operational and economic impacts. We did not receive any information through these contacts. If received, we would have included, in the rulemaking docket, a discussion of any information that may have influenced this action.

Will I Have the Opportunity to Comment Prior to the Issuance of the Rule?

Because the unsafe condition described in this document could result in the elevator control becoming jammed with consequent loss of control of the powered sailplane, we find that notice and opportunity for public prior comment are impracticable. Therefore, good cause exists for making this amendment effective in less than 30 days.

Comments Invited

How Do I Comment on This AD?

Although this action is in the form of a final rule and was not preceded by notice and opportunity for public comment, FAA invites your comments on the rule. You may submit whatever written data, views, or arguments you choose. You need to include the rule's docket number and submit your comments to the address specified under the caption ADDRESSES. We will consider all comments received on or before the closing date specified above. We may amend this rule in light of comments received. Factual information that supports your ideas and suggestions is extremely helpful in evaluating the effectiveness of this AD action and determining whether we need to take additional rulemaking action.

Are There Any Specific Portions of This AD I Should Pay Attention to?

We specifically invite comments on the overall regulatory, economic, Start Printed Page 58917environmental, and energy aspects of the rule that might suggest a need to modify the rule. You may view all comments we receive before and after the closing date of the rule in the Rules Docket. We will file a report in the Rules Docket that summarizes each FAA contact with the public that concerns the substantive parts of this AD.

How Can I Be Sure FAA Receives my Comment?

If you want us to acknowledge the receipt of your comments, you must include a self-addressed, stamped postcard. On the postcard, write “Comments to Docket No. 2001-CE-40-AD.” We will date stamp and mail the postcard back to you.

Regulatory Impact

Does This AD Impact Various Entities?

These regulations 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. Therefore, FAA has determined that this final rule does not have federalism implications under Executive Order 13132.

Does This AD Involve a Significant Rule or Regulatory Action?

We have determined that this regulation is an emergency regulation that must be issued immediately to correct an unsafe condition in aircraft, and is not a significant regulatory action under Executive Order 12866. It has been determined further that this action involves an emergency regulation under DOT Regulatory Policies and Procedures (44 FR 11034, February 26, 1979). If it is determined that this emergency regulation otherwise would be significant under DOT Regulatory Policies and Procedures, a final regulatory evaluation will be prepared and placed in the Rules Docket (otherwise, an evaluation is not required). A copy of it, if filed, may be obtained from the Rules Docket.
