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withdrawn.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).

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.

Manager, Small Airplane Directorate, Aircraft Certification Service.
