Start Preamble

AGENCY:

Federal Aviation Administration, DOT.

ACTION:

Final rule.

SUMMARY:

This amendment adopts a new airworthiness directive (AD) that applies to certain PIAGGIO AERO INDUSTRIES S.p.A. (PIAGGIO) Model P-180 airplanes. This AD requires you to replace the four defective horizontal stabilizer hinge bushings with replacement bushings. 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 replace defective bushings before they cause failure of the horizontal stabilizer. Such failure could lead to reduced or loss of control of the aircraft.

DATES:

This AD becomes effective on June 10, 2002.

The Director of the Federal Register approved the incorporation by reference of certain publications listed in the regulations as of June 10, 2002.

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 certain PIAGGIO Model P-180 airplanes. The ENAC reports that PIAGGIO has discovered four incidents of defective horizontal stabilizer hinge bushings being installed on 4 PIAGGIO Model P-180 airplanes. The defect is a missing thermal process during bushing manufacturing.

What Is the Potential Impact if FAA Took No Action?

Continued operation with defective bushings could result in failure of the horizontal stabilizer. Such failure could lead to reduced or loss of control of the aircraft.

Has FAA Taken Any Action to This Point?

We issued a proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to certain PIAGGIO Model P-180 airplanes. This proposal was published in the Federal Register as a notice of proposed rulemaking (NPRM) on February 11, 2002 (67 FR 6205). The NPRM proposed to require you to replace the defective bushings, return the bushings to PIAGGIO, and report the return to FAA.

Was the Public Invited To Comment?

The FAA encouraged interested persons to participate in the making of this amendment. We did not receive any comments on the proposed rule or on our determination of the cost to the public.

FAA's Determination

What Is FAA's Final Determination on This Issue?

After careful review of all available information related to the subject presented above, we have determined that air safety and the public interest require the adoption of the rule as proposed except for minor editorial corrections. We have determined that these minor corrections:

—Provide the intent that was proposed in the NPRM for correcting the unsafe condition; and

—Do not add any additional burden upon the public than was already proposed in the NPRM.

Cost Impact

How Many Airplanes Does This AD Impact?

We estimate that this AD affects 2 airplanes in the U.S. registry.

What Is the Cost Impact of This AD on Owners/Operators of the Affected Airplanes?

We estimate the following costs to accomplish the replacement:

Labor costParts costTotal cost per airplaneTotal cost on U.S. operators
50 workhours×$60 per hour=$3,000$400 per aircraft$3,400$3,400×2=$6,800

Regulatory Impact

Does This AD Impact Various Entities?

The regulations adopted herein 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, it is determined that this final rule does not have federalism implications under Executive Order 13132.

Does This AD Involve a Significant Rule or Regulatory Action?

For the reasons discussed above, I certify that this 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) 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 final evaluation prepared for this action is contained in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption ADDRESSES.
