Amendment 39-15777; AD 2008-26-11]
RIN 2120-AA64

 
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.
