RIN 2120-AA64
Airworthiness Directives; Piper Aircraft, Inc. (Type Certificate
Previously Held by The New Piper Aircraft, Inc.) Models PA-46-310P, PA-
46-350P, and PA-46R-350T Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM).
-----------------------------------------------------------------------
SUMMARY: We propose to supersede an existing airworthiness directive
(AD) that applies to certain Piper Aircraft, Inc. Models PA-46-310P and
PA-46-350P airplanes that are equipped with a Lewis or Transicoil
turbine inlet temperature (T.I.T.) gauge and associated probe. The
existing AD currently requires calibrating the T.I.T. system; replacing
any T.I.T. system that fails the calibration test; repetitively
replacing the T.I.T. probe on certain Model PA-46-350P airplanes; and
inserting a copy of the AD into the pilot's operating handbook (POH)
for certain airplanes. Since we issued that AD, the manufacturer has
revised related service information and added an airplane model to the
list of affected airplanes. This proposed AD would retain the actions
required by AD 99-15-04 R1, add certain Model PA-46R-350T airplanes to
the Applicability section, expand the applicability to include other
T.I.T. systems, and incorporate new service information. We are
proposing this AD to prevent improper engine operation caused by
improperly calibrated T.I.T. indicators or defective T.I.T. probes,
which could result in engine damage/failure with consequent loss of
control of the airplane.
DATES: We must receive comments on this proposed AD by February 14,
2011.

Discussion
On May 17, 2000, we issued AD 99-15-04 R1, Amendment 39-11747 (65
FR 33745, May 25, 2000), for certain Piper Aircraft, Inc. (type
certificate previously held by The New Piper Aircraft, Inc.) Models PA-
46-310P and PA-46-350P airplanes that are equipped with a Lewis or
Transicoil turbine inlet temperature (T.I.T.) gauge and associated
probe. That AD required calibrating the T.I.T. system; replacing any
T.I.T. system that fails the calibration test; repetitively replacing
the T.I.T. probe on Model PA-46-350P airplanes; and inserting a copy of
the AD into the Emergency Procedures section of the POH for certain
airplanes. That AD resulted from field reports that indicated service
accuracy problems with the existing T.I.T. system on certain Piper
Aircraft, Inc. Models PA-46-310P and PA-46-350P. We issued that AD to
prevent improper engine operation caused by improperly calibrated
T.I.T. indicators or defective T.I.T. probes, which could result in
engine damage/failure with consequent loss of control of the airplane.
Actions Since Existing AD Was Issued
Since we issued AD 99-15-04 R1, the manufacturer has revised
related service information and has added an airplane model to the list
of affected airplanes. We have also determined that the scope of this
proposed AD goes beyond only airplanes equipped with Lewis or
Transicoil gauges and/or probes.
Relevant Service Information
We reviewed Piper Aircraft, Inc. Service Bulletin No. 995C, dated
[[Page 82330]]
November 17, 2009. The service information describes procedures for
calibrating the T.I.T. system and replacing the probe.
FAA's Determination
We are proposing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other products of the same type design.
Proposed AD Requirements
This proposed AD would retain the requirements of AD 99-15-04 R1.
This proposed AD would also add certain Model PA-46R-350T airplanes to
the Applicability section, expand the applicability to include other
T.I.T. systems, and incorporate new service information.
Costs of Compliance
We estimate that this proposed AD affects 898 airplanes of U.S.
registry.
We estimate the following costs to comply with this proposed AD:

----------------------------------------------------------------------------------------------------------------
Cost per Cost on U.S.

----------------------------------------------------------------------------------------------------------------
The requirements of this proposed AD add no additional economic
burden other than the addition of an airplane model to the
Applicability section.
We estimate the following costs to do any necessary replacements
that would be required based on the results of the proposed inspection.
We have no way of determining the number of aircraft that might need
these replacements:

Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, Section 106, describes the
authority of the FAA Administrator. Subtitle VII, Aviation Programs,
describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701, ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
Regulatory Findings
We have determined that this proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD would not
have a substantial direct effect 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.
For the reasons discussed above, I certify that the proposed
regulation:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) 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.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
The Proposed Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:
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. The FAA amends Sec. 39.13 by removing airworthiness directive
(AD) 99-15-04 R1, Amendment 39-11747 (65 FR 33745, May 25, 2000), and
adding the following new AD:
Piper Aircraft, Inc. (Type Certificate Previously Held by The New
Piper Aircraft, Inc.): Docket No. FAA-2010-1295; Directorate
Identifier 2010-CE-060-AD.
Comments Due Date
(a) The FAA must receive comments on this AD action by February
14, 2011.
Affected ADs
(b) This AD supersedes AD 99-15-04 R1, Amendment 39-11747.
Applicability
(c) This AD applies to the following Piper Aircraft, Inc. (type
certificate previously held by The New Piper Aircraft, Inc.) Models
PA-
[[Page 82331]]
46-310P, PA-46-350P, and PA-46R-350T airplanes that:
(1) Are certificated in any category; and
(2) Equipped with a turbine inlet temperature (T.I.T.) system
identified in table 1 of this AD. Relief from this AD is available
only if the gauge and probe are replaced through STC and not if a
second turbine inlet temperature gauge was installed while retaining
the Lewis or Transicoil T.I.T. gauge and probe.

(1) If the turbine inlet temperature indication fails or is
suspected of failure during takeoff, climb, descent, or landing,
maintain FULL RICH mixture to assure adequate fuel flow for engine
cooling.
