14 CFR Part 39
[Docket No. 96-CE-28-AD]
RIN 2120-AA64
Airworthiness Directives; Industrie Aeronautiche E Meccaniche
Model Piaggio P-180 Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Proposed rule; withdrawal.
-----------------------------------------------------------------------
SUMMARY: This document withdraws a notice of proposed rulemaking (NPRM)
that would have applied to certain Industrie Aeronautiche E Meccaniche
(I.A.M.) Model Piaggio P-180 airplanes. The proposed action would have
required replacing certain AlliedSignal Aerospace outflow/safety valves
in the pressurization system with new or serviceable valves. During the
comment period of this NPRM, the Transport Airplane Directorate of the
Federal Aviation Administration (FAA) issued AD 96-18-20 to address the
same condition on these I.A.M. Model Piaggio P-180 airplanes. With this
in mind, the FAA has determined that the proposed rule should be
withdrawn. This withdrawal does not prevent the FAA from initiating
future rulemaking on this subject.

SUPPLEMENTARY INFORMATION:
Events Leading to This Action
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 are registered in
the United States and have an AlliedSignal Aerospace outflow/safety
valve installed was published in the Federal Register on August 12,
1996 (61 FR 41753). The action proposed to require replacing outflow/
safety valves with new or serviceable valves.
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.
During the comment period of this notice of proposed rulemaking
(NPRM), the Transport Airplane Directorate of the FAA issued AD 96-18-
20, Amendment 39-9747 (61 FR 47409, September 9, 1996), to address the
same condition on these I.A.M. Model Piaggio P-180 airplanes. The
continued airworthiness authority of these airplanes resides with the
Small Airplane Directorate because I.A.M. Model Piaggio P-180 airplanes
are type certificated under part 23 of the Federal Aviation Regulations
(14 CFR part 23). However, because AD 96-18-20 is already in effect,
the FAA has decided to withdraw the NPRM issued by the Small Airplane
Directorate.
Withdrawal of this NPRM constitutes only such action, and does not
preclude the agency from issuing future rulemaking on this issue, nor
does it commit the agency to any course of action in the future.
Since this action only withdraws an NPRM, it is neither a proposed
nor a final rule and therefore, is not covered under Executive Order
12866, the Regulatory Flexibility Act, or DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979).
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation Safety, Safety.
The Withdrawal
Accordingly, the notice of proposed rulemaking, Docket No. 96-CE-
28-AD, published in the Federal Register on August 12, 1996 (61 FR
41753), is withdrawn.
Issued in Kansas City, Missouri, on December 2, 1996.
Michael Gallagher,
Manager, Small Airplane Directorate, Aircraft Certification Service.
