Piper Aircraft, Inc.) Models PA-46-310P, PA-46-350P, and PA-46R-350T Airplanes
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
SUMMARY: We are superseding 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. That AD currently requires
cleaning, inspecting, and 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 airplanes; and inserting a copy of the
AD into the pilot's operating handbook (POH) for certain airplanes. This new AD retains the actions
required by the previous AD (AD 99-15-04 R1), adds certain Model PA-46R-350T airplanes to the
Applicability section, expands the applicability to include other T.I.T. systems, and incorporates new
service information. This AD was prompted by the manufacturer revising related service information
and adding an airplane model to the list of affected airplanes. We are issuing 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: This AD is effective May 6, 2011.
The Director of the Federal Register approved the incorporation by reference of certain
publications listed in the AD as of May 6, 2011.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD
99-15-04 R1, Amendment 39-11747 (65 FR 33745, May 25, 2000). That AD applies to 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 T.I.T. gauge and associated
probe. The NPRM published in the Federal Register on December 30, 2010 (75 FR 82329). That
NPRM proposed to continue to require cleaning, inspecting, and calibrating the T.I.T. system on
certain airplanes; replacing any T.I.T. system that fails the inspection and calibration test; repetitively
replacing the T.I.T. probe on certain airplanes; and inserting a copy of the AD into the pilot's
operating handbook (POH). That NPRM also proposed to 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.
Comments
We gave the public the opportunity to participate in developing this AD. We received no
comments on the NPRM or on the determination of the cost to the public.
Conclusion
We reviewed the relevant data and determined that air safety and the public interest require
adopting the AD as proposed except for minor editorial changes. We have determined that these
minor changes:
Are consistent with the intent that was proposed in the NPRM for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was already proposed in the NPRM.
Costs of Compliance
We estimate that this AD affects 898 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

The requirements of this 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 will be required based on
the results of the inspection. We have no way of determining the number of aircraft that might need
these replacements:
On-Condition Costs
Action Labor cost Parts cost Cost per product
Replace probe 1 work-hour X $85 per hour = $85 $384 $469
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 AD will not have federalism implications under Executive Order
13132. This AD will 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 this AD:
(1) Is not a ''significant regulatory action'' under Executive Order 12866,
(2) Is not a ''significant rule'' under DOT Regulatory Policies and Procedures (44 FR 11034,
February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
4
(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

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR part 39 to supersede AD
99-15-04 R1, Amendment 39-11747 (65 FR 33745, May 25, 2000). That AD applies to 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 T.I.T. gauge and associated
probe. The NPRM published in the Federal Register on December 30, 2010 (75 FR 82329). That
NPRM proposed to continue to require cleaning, inspecting, and calibrating the T.I.T. system on
certain airplanes; replacing any T.I.T. system that fails the inspection and calibration test; repetitively
replacing the T.I.T. probe on certain airplanes; and inserting a copy of the AD into the pilot's
operating handbook (POH). That NPRM also proposed to 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.
Comments
We gave the public the opportunity to participate in developing this AD. We received no
comments on the NPRM or on the determination of the cost to the public.
Conclusion
We reviewed the relevant data and determined that air safety and the public interest require
adopting the AD as proposed except for minor editorial changes. We have determined that these
minor changes:
Are consistent with the intent that was proposed in the NPRM for correcting the unsafe
condition; and
Do not add any additional burden upon the public than was already proposed in the NPRM.
Costs of Compliance
We estimate that this AD affects 898 airplanes of U.S. registry.
We estimate the following costs to comply with this AD:

The requirements of this 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 will be required based on
the results of the 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 AD will not have federalism implications under Executive Order
13132. This AD will 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 this AD:
(1) Is not a ''significant regulatory action'' under Executive Order 12866,
(2) Is not a ''significant rule'' under DOT Regulatory Policies and Procedures (44 FR 11034,
February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
4
(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.
