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:

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

(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.
(2) If the turbine inlet temperature indication fails or is suspected of failure after cruise power has been set, maintain cruise power setting and lean to 6 gallons per hour (GPH) fuel flow above that specified in the Power Setting Table in Section 5 of the
AFM/POH. Continually monitor engine cylinder head and oil temperatures to avoid exceeding temperature limits.
