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 all Piaggio Aero Industries S.p.A. Model P-180 airplanes. This AD requires you to inspect for proper clearance between the first outboard flap control rod and the bleed air duct for interference, replace worn or damaged parts or correct interference, and adjust clearance. This AD is the result of mandatory continuing airworthiness information (MCAI) issued by the airworthiness authority for Italy. The actions specified by this AD are intended to detect and correct interference or damage of the first outboard flap control rod and bleed air duct, which could result in failure of the flap control rod. Such failure could lead to loss of airplane control.

DATES:

This AD becomes effective on December 17, 2002.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulation as of December 17, 2002.

The Federal Aviation Administration (FAA) must receive any comments on this rule on or before January 22, 2003.

ADDRESSES:

Submit comments to FAA, Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 2002-CE-48-AD, 901 Locust, Room 506, Kansas City, Missouri 64106. You may view any comments at this location between 8 a.m. and 4 p.m., Monday through Friday, except Federal holidays. You may also send comments electronically to the following address: 9-ACE-7-Docket@faa.gov. Comments sent electronically must contain “Docket No. 2002-CE-48-AD” in the subject line.

Discussion

What Events Have Caused This AD?

The Ente Nazionale per l' Aviazione Civile (ENAC), which is the airworthiness authority for Italy, recently notified FAA that an unsafe condition may exist on all Piaggio Model P-180 airplanes. The ENAC reports an incorrect installation with insufficient clearance between the first outboard flap control rod and the bleed air duct. This caused interference with consequent loss of flap control.

What Are the Consequences If the Condition Is Not Corrected?

The failure of the flap control rod could lead to loss of airplane control.

Is There Service Information That Applies to This Subject?

PIAGGIO has issued Alert Service Bulletin No. 80-0182, Original Issue: June 7, 2002.

The service bulletin includes procedures for:

—Inspecting for interference between the first outboard flap control rod and bleed air duct, and inspecting for damage or wear in this area;

—Replacing damaged parts or correcting interference; and

—Correcting where clearance is less than the correct value, but no interference is found.

What Action Did the ENAC Take?

The ENAC classified this service bulletin as mandatory and issued Italian AD Number 2002-442, dated August 22, 2002, in order to ensure the continued airworthiness of these airplanes in Italy.

Was This in Accordance With the Bilateral Airworthiness Agreement?

This airplane model is manufactured in Italy and is 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 ENAC 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 ENAC; 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 Piaggio Model P-180 airplanes of the same type design;

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

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

What Does This AD Require?

This AD requires you to incorporate the actions in the previously-referenced service bulletin.

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 Start Printed Page 69995in failure of the flap control rod and loss of airplane control, 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, environmental, 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. 2002-CE-48-AD.” We will date stamp and mail the postcard back to you.

Compliance Time of this AD

What Is the Compliance Time of This AD?

The compliance time of this AD is within the next 15 days after the effective date of the AD.

Why Is the Compliance Time Presented in Calendar Time Instead of Hours Time-in-Service (TIS)?

The compliance of this AD is presented in calendar time instead of hours TIS because the affected first outboard flap control rod and bleed air duct components are unsafe as a result of an incorrect installation. The problem has the same chance of existing on an airplane with 50 hours TIS as it would for an airplane with 1,000 hours TIS. Therefore, we believe that a compliance time of 15 days will:

—Ensure that the unsafe condition does not go undetected for a long period of time on the affected airplanes; and

—Not inadvertently ground any of the affected airplanes.

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.
