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 that are equipped with a certain freon air
conditioning system. This AD requires inspecting the baggage
compartment for stringer or air cycle machine (ACM) by-pass duct
damage, repairing any damage found, and modifying the freon air inlet
duct and electrical wiring. This AD results from trim system
malfunction on one of the affected airplanes, resulting from contact
between the freon air inlet duct and the electrical wiring. The actions
specified by this AD are intended to prevent trim system malfunction
caused by contact between the freon air inlet duct and electrical
wiring, which could result in loss of control of the airplane.
DATES: Effective August 29, 1997.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director
[[Page 36449]]
of the Federal Register as of August 29, 1997.
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 Assistant Chief

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 of the same type design that have either a
freon air conditioning system incorporated in accordance with I.A.M.
Kit 80KS00004-* * * (801/803/805/807) or a Keith Freon Air Conditioning
System installed in accordance with Supplemental Type Certificate (STC)
SA2762CE was published in the Federal Register as a notice of proposed
rulemaking (NPRM) on February 14, 1997 (62 FR 6890). The NPRM proposed
to require inspecting the baggage compartment for stringer or air cycle
machine (ACM) by-pass duct damage, repairing any damage found, and
modifying the freon air inlet duct and electrical wiring (Modification
No. 80M000014). Accomplishment of the proposed inspection and
modification as specified in the NPRM would be in accordance with
Piaggio Avante P-180 Service Bulletin 80-00083, Original Issue:
December 7, 1994; Revision No. 1: December 5, 1995.
The NPRM was the result of trim system malfunction on one of the
affected airplanes, resulting from contact between the freon air inlet
duct and the electrical wiring.
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 18 workhours
(inspection: 2 workhours; modification: 16 workhours) per airplane to
accomplish the required 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 the AD on U.S.
operators is estimated to be $5,900 or $1,180 per airplane.
The above figures only take into account the cost of the inspection
and modification, and do not account for the cost of replacing any
parts found damaged during the inspection. The FAA has no way of
determining how many airplanes may be found damaged during the
inspections.
The FAA knows of no affected airplane owner/operator (of the five
affected) that has already accomplished the required action.
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.
