Airworthiness Directives; Industrie Aeronautiche e Meccaniche 
Model Piaggio P-180 Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This amendment adopts a new airworthiness directive (AD) that 
applies to certain Industrie Aeronautiche e Meccaniche (I.A.M.) Model 
Piaggio P-180 airplanes. This AD requires modifying the low pitch stop 
switch support. 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 prevent low 
pitch stop switch support displacement, which could result in an 
improper cockpit indication that the propeller is in the Beta range and 
cause loss of control of the airplane.

DATES: Effective July 18, 1998.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of July 18, 1998.

ADDRESSES: Service information that applies to this AD may be obtained 
from Industrie Aeronautiche e Meccaniche Rinaldo Piaggio S.p.A., Via 
Cibrario, 4 16154 Genoa, Italy. This information may also be examined 
at the Federal Aviation Administration (FAA), Central Region, Office of 
the Regional Counsel, Attention: Rules Docket No. 97-CE-141-AD, Room 
1558, 601 E. 12th Street, Kansas City, Missouri 64106; or at the Office 
of the Federal Register, 800 North Capitol Street, NW, suite 700, 
Washington, DC.

FOR FURTHER INFORMATION CONTACT: Mr. David O. Keenan, Project Officer, 
FAA, Small Airplane Directorate, Aircraft Certification Service, 1201 
Walnut, suite 900, Kansas City, Missouri 64106; telephone: (816) 426-
6934; facsimile: (816) 426-2169.

SUPPLEMENTARY INFORMATION:

Events Leading to the Issuance of This AD

    A proposal to amend part 39 of the Federal Aviation Regulations (14 
CFR part 39) to include an AD that would apply to certain I.A.M. Model 
Piaggio P-180 airplanes was published in the Federal Register as a 
notice of proposed rulemaking (NPRM) on March 2, 1998 (63 FR 10157). 
The NPRM proposed to require modifying the low pitch stop switch 
support. Accomplishment of the proposed action as specified in the NPRM 
would be in accordance with I.A.M. Piaggio Service Bulletin (Mandatory) 
No. SB-80-0080, dated July 3, 1997.
    The NPRM was the result of mandatory continuing airworthiness 
information (MCAI) issued by the airworthiness authority for Italy.
    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were received on the 
proposed rule or the FAA's determination of the cost to the public.

The FAA's Determination

    After careful review of all available information related to the 
subject presented above, the FAA has determined that air safety and the 
public interest require the adoption of the rule as proposed except for 
minor editorial corrections. The FAA has determined that these minor 
corrections will not change the meaning of the AD and will not add any 
additional burden upon the public than was already proposed.

Cost Impact

    The FAA estimates that 5 airplanes in the U.S. registry will be 
affected by this AD, that it will take approximately 6 workhours per 
airplane to accomplish this action, and that the average labor rate is 
approximately $60 an hour. Parts cost approximately $100 per airplane. 
Based on these figures, the total cost impact of this AD on U.S. 
operators is estimated to be $2,300, or $460 per airplane.

Regulatory Impact

    The regulations adopted herein will not have substantial direct 
effects 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, in 
accordance with Executive Order 12612, it is determined that this final 
rule does not have sufficient federalism implications to warrant the 
preparation of a Federalism Assessment.
    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.

Sec. 39.13  [Amended]

    2. Section 39.13 is amended by adding a new airworthiness directive 
(AD) to read as follows:

98-12-13  Industrie Aeronautiche E Meccaniche: Amendment 39-10569; 
Docket No. 97-CE-141-AD.

    Applicability: Model Piaggio P-180 airplanes, serial numbers 
1001, 1002, 1004, and 1006 through 1033, certificated in any 
category.

    Note 1: This AD applies to each airplane identified in the 
preceding applicability provision, regardless of whether it has been 
modified, altered, 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 (c) 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 the unsafe condition has not been 
eliminated, the request should include specific proposed actions to 
address it.

    Compliance: Required within the next 150 hours time-in-service 
(TIS) after the effective date of this AD, unless already 
accomplished.
    To prevent low pitch stop switch support displacement, which 
could result in an improper cockpit indication that the propeller is 
in the Beta range and cause loss of control of the airplane, 
accomplish the following:
    (a) Modify the low pitch stop switch support in accordance with 
Industrie Aeronautiche e Meccaniche Piaggio Service Bulletin 
(Mandatory) No. SB-80-0080, dated July 3, 1997.

sections 21.197 and 21.199 of the Federal Aviation Regulations (14 
CFR 21.197 and 21.199) to operate the airplane to a location where 
the requirements of this AD can be accomplished.
    (c) An alternative method of compliance or adjustment of the 
compliance time that provides an equivalent level of safety may be 
approved by the Manager, Small Airplane Directorate, 1201 Walnut, 
suite 900, Kansas City, Missouri 64106. The request shall be 
forwarded through an appropriate FAA Maintenance Inspector, who may 
add comments and then send it to the Manager, Small Airplane 
Directorate.

    Note 2: Information concerning the existence of approved 
alternative methods of compliance with this AD, if any, may be 
obtained from the Small Airplane Directorate.

    (d) Questions or technical information related to I.A.M. Piaggio 
Service Bulletin (Mandatory) No. SB-80-0080, dated July 3, 1997, 
should be directed to I.A.M. Rinaldo Piaggio S.p.A., Via Cibrario, 4 
16154 Genoa, Italy. This service information may be examined at the
