14 CFR Part 39

[Docket No. 2002-CE-02-AD; Amendment 39-12712; AD 2002-08-04]
RIN 2120-AA64


Airworthiness Directives; PIAGGIO AERO INDUSTRIES S.p.A. Model P-
180 Airplanes

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.

ADDRESSES: You may get the service information referenced in this AD 
from PIAGGIO AERO INDUSTRIES S.p.A, Via Cibrario 4, 16154 Genoa, Italy; 
telephone: +39 010 6481 856; facsimile: +39 010 6481 374. You may view

SUPPLEMENTARY INFORMATION:

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:

----------------------------------------------------------------------------------------------------------------
                                                           Total cost per
            Labor cost                    Parts cost          airplane          Total cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
50 workhours x $60 per hour=$3,000  $400 per aircraft....          $3,400  $3,400 x 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.

or repaired in the area subject to the requirements of this AD. For 
airplanes that have been modified, altered, or repaired so that the 
performance of the requirements of this AD is affected, the owner/
operator must request approval for an alternative method of 
compliance in accordance with paragraph (e) of this AD. The request 
should include an assessment of the effect of the modification, 
alteration, or repair on the unsafe condition addressed by this AD; 
and, if you have not eliminated the unsafe condition, specific 
actions you propose to address it.
