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 all Industrie Aeronautiche e Meccaniche (I.A.M.) Model Piaggio P-180 airplanes. This AD requires inspecting the upper and lower engine nacelle inner panels for any loose or partially detached inner film, and removing any loose or partially detached inner film. 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 the accumulation of loose particles on the engine inlet screen caused by film delamination, which could result in reduced engine power and possible loss of airplane control.
DATES: Effective May 10, 1999.
The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of May 10, 1999.
ADDRESSES: Service information that applies to this AD may be obtained from I.A.M. 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

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 all I.A.M. Model Piaggio P-180 airplanes was published in the Federal Register as a notice of proposed rulemaking (NPRM) on December 30, 1998 (63 FR 71799). The NPRM proposed to require inspecting the upper and lower engine nacelle inner panels for any loose or partially detached inner film, and removing any loose or partially detached inner film. Accomplishment of the proposed actions as specified in the NPRM would be in accordance with Piaggio Service Bulletin (Mandatory) No.: SB-80- 0101, Original Issue: May 6, 1998.
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.
Compliance Time of This AD
Although the reduced engine power that will result if loose film particles accumulated on the engine inlet screen will only be unsafe during flight, this condition is not a result of the number of times the airplane is operated. The loose film occurs over time because of weather and climate conditions. For this reason, the FAA has determined that a compliance based on calendar time will be utilized in this AD in order to assure that the unsafe condition is addressed on all airplanes in a reasonable time period.
Cost Impact
The FAA estimates that 5 airplanes in the U.S. registry will be affected by this AD, that it will take approximately 7 workhours per airplane to accomplish the inspection and film removal, and that the average labor rate is approximately $60 an hour. There are no parts required to accomplish this AD. Based on these figures, the total cost impact of this AD on U.S. operators is estimated to be $2,100, or $420 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.

Adoption of the Amendment
Accordingly, pursuant to the authority delegated to me by the Administrator, the Federal Aviation Administration amends part 39 of the Federal Aviation Regulations (14 CFR part 39) as follows:
PART 39--AIRWORTHINESS DIRECTIVES
-
The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
-
Section 39.13 is amended by adding a new airworthiness directive (AD) to read as follows:
99-07-10 Industrie Aeronautiche e Meccaniche: Amendment 39-11095; Docket No. 98-CE-97-AD.
Applicability: Model Piaggio P-180 airplanes, all serial numbers, 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 as indicated in the body of this AD, unless already accomplished.
To prevent the accumulation of loose particles on the engine inlet screen caused by film delamination, which could result in reduced engine power and possible loss of airplane control, accomplish the following:
(a) Within the next 6 calendar months after the effective date of this AD, inspect the upper and lower engine nacelle inner panels for any loose or partially detached inner film, in accordance with the ACCOMPLISHMENT INSTRUCTIONS section of Piaggio Service Bulletin (Mandatory) No.: SB-80-0101, Original Issue: May 6, 1998. Prior to further flight after the inspection, remove any loose or partially detached inner film in accordance with the service bulletin.
(b) Special flight permits may be issued in accordance with 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 times 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 Piaggio Service Bulletin (Mandatory) No.: SB-80-0101, Original Issue: May 6, 1998, 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 FAA, Central Region,
