Federal Register Abstract

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.

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

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:
<bullet> Are consistent with the intent that was proposed in the
NPRM for correcting the unsafe condition; and
<bullet> 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:

Estimated Costs
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product Cost on U.S. operators
----------------------------------------------------------------------------------------------------------------
Clean and inspect the T.I.T 1 work-hour x $85 Not applicable.... $85 $85 x 780 affected airplanes
gauge and probe for certain per hour = $85. = $66,300.
Models PA-46-310P and PA-46-
350P airplanes.
Calibrate the T.I.T. gauge for 4 work-hours x $85 Not applicable.... 340 340 x 427 affected airplanes
certain Models PA-46-310P and per hour = $340. = $145,180.
PA-46-350P airplanes.
Incorporate emergency 1 work-hour x $85 Not applicable.... 85 85 x 898 affected airplanes
procedures into POH. per hour = $85. = $76,330.
----------------------------------------------------------------------------------------------------------------

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
----------------------------------------------------------------------------------------------------------------
Cost per
Action Labor cost Parts cost product
----------------------------------------------------------------------------------------------------------------
Replace probe................................ 1 work-hour x $85 per hour = $384 $469
$85.
----------------------------------------------------------------------------------------------------------------

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) 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.

Adoption of the Amendment

Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:

Appendix 1 to AD 2011-06-10--Model PA-46-310P (Malibu); Emergency
Procedures for the Pilot's Operating Handbook (POH)

(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.
