Abstract
The FAA is withdrawing a notice of proposed rulemaking (NPRM) and supplemental notice of proposed rulemaking (SNPRM) that proposed to supersede Airworthiness Directive (AD) 92-13-04 for certain Piper Aircraft Corporation (now Piper Aircraft, Inc.) (Piper) Model PA-23-150 (type certificated as PA-23) and PA-23-160 airplanes. AD 92-13-04 requires preflight water draining procedures for the fuel tanks on the affected airplanes. In June 2022, the FAA calculated the quantitative risk using current methods, which were not available at the time the NPRM and SNPRM were issued. The short- and long-term risk assessment calculations establish that an AD for the additional actions and the additional airplane models that were proposed to be added in the NPRM and SNPRM is not warranted. Accordingly, the NPRM and SNPRM are withdrawn.

Airworthiness Directives; Piper Aircraft, Inc. (Type Certificate
Previously Held by The New Piper Aircraft Inc. and Piper Aircraft
Corporation) Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Proposed rule; withdrawal.
-----------------------------------------------------------------------
SUMMARY: The FAA is withdrawing a notice of proposed rulemaking (NPRM)
and supplemental notice of proposed rulemaking (SNPRM) that proposed to
supersede Airworthiness Directive (AD) 92-13-04 for certain Piper
Aircraft Corporation (now Piper Aircraft, Inc.) (Piper) Model PA-23-150
(type certificated as PA-23) and PA-23-160 airplanes. AD 92-13-04
requires preflight water draining procedures for the fuel tanks on the
affected airplanes. In June 2022, the FAA calculated the quantitative
risk using current methods, which were not available at the time the
NPRM and SNPRM were issued. The short- and long-term risk assessment
calculations establish that an AD for the additional actions and the
additional airplane models that were proposed to be added in the NPRM
and SNPRM is not warranted. Accordingly, the NPRM and SNPRM are
withdrawn.
DATES: As of October 31, 2022, the proposed rules, which published in
the Federal Register on September 19, 1995 (60 FR 48433), and February
12, 1998 (63 FR 7085), are withdrawn.

SUPPLEMENTARY INFORMATION:
Background
The FAA issued an NPRM that proposed to amend part 39 of the
Federal Aviation Regulations (14 CFR part 39) to supersede AD 92-13-04,
Amendment 39-8274 (57 FR 24938; June 12, 1992) (AD 92-13-04), which
applies to certain serial-numbered Piper Model PA-23-150 (type
certificated as PA-23) and PA-23-160 airplanes. The NPRM published in
the Federal Register on September 19, 1995 (60 FR 48433). The FAA
subsequently issued an SNPRM, which published in the Federal Register
on February 12, 1998 (63 FR 7085).
The NPRM proposed to:
<bullet> Add certain Model PA-23, PA-23-235, and PA-23-250
airplanes to the applicability;
<bullet> Retain the preflight draining procedures required by AD
92-13-04 to require incorporating pilots' operating handbook (POH)
revisions for Piper Model PA-23-150 and PA-23-160 airplanes that are
not equipped with a dual fuel drain kit, part number (P/N) 765-363
(unless already accomplished). The POH revisions are included in Piper
Service Bulletin (SB) No. 827A, dated November 4, 1988 (Piper SB No.
827A);
<bullet> Require installation of external fuel ramp assemblies on
all the affected airplanes in accordance with Floats and Fuel Cells
Engineering Specification 2810-002, Revision A, dated March 21, 1995;
and
<bullet> Delay the compliance for airplanes with Piper Fuel Tank
Wedge Kit, P/N 599-367, incorporated in accordance with Piper SB 932A,
dated August 30, 1990, until a new fuel tank is installed.
The SNPRM proposed minor changes to the NPRM and was issued as an
SNPRM based on the amount of time between the NPRM and the SNPRM.
Actions Since the SNPRM Was Issued
In June 2022, the FAA calculated the quantitative risk of a failure
using the current method of assessing risk. This method used, along
with the breadth of data that the FAA current has, was not available in
1995/1998 and is the quantitative standard the FAA's continued
operational safety community uses to currently assess risk. The FAA
risk assessment estimated the future risk of water-in-the-fuel within a
one-year period (short-term) and over the next 20 years (long-term) for
all Piper PA-23 airplanes, from the first year of operation (1955) to
present day (2022). All probable or contributable reported
[[Page 65535]]
incidents attributed to water-in-the-fuel that were reported were
considered. The short- and long-term risk assessment calculations
establish that an AD for the additional actions and the additional
airplane models that were proposed to be added in the NPRM and SNPRM is
not warranted. Accordingly, the NPRM and SNPRM are to be withdrawn.
The FAA will continue to monitor this situation and take
appropriate action as required.
Withdrawal of the NPRM and SNPRM 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.
Regulatory Findings
Since this action only withdraws an NPRM and SNPRM, it is neither a
proposed AD nor a final rule and therefore, not covered under Executive
Order 12866 or the Regulatory Flexibility Act.

The Withdrawal
Accordingly, the notice of proposed rulemaking, which published in
the Federal Register on September 19, 1995 (60 FR 48433), and the
supplemental notice of proposed rulemaking, which published in the
Federal Register on February 12, 1998 (63 FR 7085), are withdrawn.
Issued on October 20, 2022.
