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

AGENCY: Federal Aviation Administration, DOT.

ACTION: Notice of proposed rulemaking (NPRM).

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

SUMMARY: This document proposes to adopt a new airworthiness directive 
(AD) that would apply to certain Industrie Aeronautiche e Meccaniche 
(I.A.M.) Model Piaggio P-180 airplanes. The proposed AD would require 
inspecting the elevator and aileron control retaining pins for proper 
installation and damage, and replacing any improperly installed or 
damaged pins. The proposed AD is the result of mandatory continuing 
airworthiness information (MCAI) issued by the airworthiness authority 
for Italy. The actions specified by the proposed AD are intended to 
prevent the retaining pins from interfering with the flight control 
elements, which could result in loss of the cable retaining function 
with consequent loss of control of the airplane.

DATES: Comments must be received on or before October 13, 1998.

City, Missouri 64106.

Discussion

    The Registro Aeronautico Italiano (R.A.I.), which is the 
airworthiness authority for Italy, recently notified the FAA that an 
unsafe condition may exist on certain I.A.M. Model Piaggio P-180 
airplanes. The R.A.I. reports that the retaining pins located in the 
aileron and elevator control systems were improperly installed on one 
of the affected airplanes. The manufacturer believes that the retaining 
pin may have been improperly installed at the factory.
    This condition, if not corrected, could result in loss of the cable 
retaining function with consequent loss of control of the airplane.

Relevant Service Information

    I.A.M. has issued Piaggio Service Bulletin (Mandatory) No. SB-80-
0089, dated May 22, 1996, which specifies procedures for removing the 
vertical stabilizer rear fairing and inspecting the elevator and 
aileron control retaining pins for proper installation and damage, and 
replacing any improperly installed or damaged pins.
    The R.A.I. classified this service bulletin as mandatory and issued 
Italian AD No. 96-158, dated July 1, 1996, in order to assure the 
continued airworthiness of these airplanes in Italy.

The FAA's Determination

    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 R.A.I. has kept the FAA informed 
of the situation described above.
    The FAA has examined the findings of the R.A.I.; reviewed all 
available information, including the service information referenced 
above; and determined that AD action is necessary for products of this 
type design that are certificated for operation in the United States.

Explanation of the Provisions of the Proposed AD

    Since an unsafe condition has been identified that is likely to 
exist or develop in other I.A.M. Model Piaggio P-180 airplanes of the 
same type design registered in the United States, the FAA is proposing 
AD action. The proposed AD would require inspecting the elevator and 
aileron control retaining pins for proper installation and damage, and 
replacing any improperly installed or damaged pins. Accomplishment of 
the proposed installation would be required in accordance with I.A.M. 
Piaggio Service Bulletin (Mandatory) No. SB-80-0089, dated May 22, 
1996.

Cost Impact

    The FAA estimates that 5 airplanes in the U.S. registry would be 
affected by the proposed inspection, that it would take approximately 3 
workhours per airplane to accomplish the proposed inspection, and that 
the average labor rate is approximately $60 an hour. Based on these 
figures, the total cost impact of the proposed inspection on U.S. 
operators is estimated to be $900, or $180 per airplane. These figures 
do not account for any damaged or improperly installed retaining pins 
found during the proposed inspection that would need to be replaced.

Regulatory Impact

    The regulations proposed herein would 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 
proposal would 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) if promulgated, 
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 draft regulatory evaluation 
prepared for this action has been placed in the Rules Docket. A copy of 
it may be obtained by contacting the Rules Docket at the location 
provided under the caption ADDRESSES.

The Proposed Amendment

    Accordingly, pursuant to the authority delegated to me by the 
Administrator, the Federal Aviation Administration proposes to amend 
part 39 of the Federal Aviation Regulations (14 CFR part 39) as 
follows:

[[Page 48143]]

PART 39--AIRWORTHINESS DIRECTIVES

    1. The authority citation for part 39 continues to read as follows:

    Authority: 49 U.S.C. 106(g), 40113, 44701.

Sec. 39.13  [Amended]

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

Industrie Aeronautiche E Meccaniche: Docket No. 98-CE-45-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 as indicated in the body of this AD, unless 
already accomplished.

    To prevent the retaining pins from interfering with the flight 
control elements, which could result in loss of the cable retaining 
function with consequent loss of control of the airplane, accomplish 
the following:
    (a) Within the next 100 hours time-in-service after the 
effective date of this AD, inspect the elevator and aileron control 
retaining pins for proper installation and damage in accordance with 
the Accomplishment Instructions section in I.A.M. Piaggio Service 
Bulletin (Mandatory) No. SB-80-0089, dated May 22, 1996. Prior to 
further flight, replace any improperly installed or damaged pins 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 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 Small Airplane Directorate.

    (d) Questions or technical information related to Piaggio 
Service Bulletin (Mandatory) No. SB-80-0089, dated May 22, 1996, 
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, Office of the Regional Counsel, Room 1558, 601 
E. 12th Street, Kansas City, Missouri 64106.

    Note 3: The subject of this AD is addressed in Italian AD No. 
96-158, dated July 1, 1996.

    Issued in Kansas City, Missouri, on September 1, 1998.
