Amendment 39-15777; AD 2008-26-11]

Airworthiness Directives; Piper Aircraft, Inc. Models PA-46-350P,
PA-46R-350T, and PA-46-500TP Airplanes

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: We are adopting a new airworthiness directive (AD) for certain
Piper Aircraft, Inc. (Piper) Models PA-46-350P, PA-46R-350T, and PA-46-
500TP airplanes. This AD requires you to install a stall warning heat
control modification kit. This AD results from ice forming on the stall
vane heater during flights into icing conditions with the landing gear
down. We are issuing this AD to prevent ice from forming on the stall
vane, which may result in failure of the stall warning system. This
failure could result in the pilot being unaware of an approaching stall
situation.

DATES: This AD becomes effective on January 28, 2009.
On January 28, 2009, the Director of the Federal Register approved
the incorporation by reference of certain publications listed in this
AD.

SUPPLEMENTARY INFORMATION:

Discussion

On October 3, 2008, we issued a proposal to amend part 39 of the
Federal Aviation Regulations (14 CFR part 39) to include an AD that
would apply to certain Piper Models PA-46-350P, PA-46R-350T, and PA-46-
500TP airplanes. This proposal was published in the Federal Register as
a notice of proposed rulemaking (NPRM) on October 10, 2008 (73 FR
60201). The NPRM proposed to require you to install a stall warning
heat control modification kit.

Comments

We provided the public the opportunity to participate in developing
this AD. We received no comments on the proposal or on the
determination of the cost to the public.

Conclusion

We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed
except for minor editorial corrections. We have determined that these
minor corrections:
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 803 airplanes in the U.S.
registry.
We estimate the following costs to do the modification:

----------------------------------------------------------------------------------------------------------------
Total cost per Total cost on
Labor cost Parts cost airplane U.S. operators
----------------------------------------------------------------------------------------------------------------
1.5 work-hours x $80 per hour = $120......................... $95 $215 $172,645
----------------------------------------------------------------------------------------------------------------

Warranty credit may be given to the extent noted in the service
bulletin.

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

[[Page 78935]]

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 AD.

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 the DOT Regulatory Policies
and Procedures (44 FR 11034, February 26, 1979); and
3. 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.
We prepared a summary of the costs to comply with this AD (and
other information as included in the Regulatory Evaluation) and placed
it in the AD Docket. You may get a copy of this summary by sending a
request to us at the address listed under ADDRESSES. Include ``Docket
No. FAA-2008-1085; Directorate Identifier 2008-CE-057-AD'' in your
request.
