14 CFR Part 39

Amendment 39-15867; AD 2009-07-08]

Airworthiness Directives; Piper Aircraft, Inc. Models PA-46-350P
and PA-46R-350T 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. Models PA-46-350P and PA-46R-350T airplanes. This
AD requires you to inspect the 35-amp and 250-amp current limiters to
verify they are installed in the proper locations and correct the
installation if the current limiters are not installed in the proper
locations. This AD also limits operation to ``only under day visual
flight rules (VFR)'' until the current limiter installation is
inspected and corrected. This AD results from three reports of
incorrectly installed current limiters. We are issuing this AD to
detect and correct incorrect installation of 35-amp and 250-amp current
limiters, which could result in failure of the 35-amp current limiter
if installed in the 250-amp location. This failure could lead to a
total loss of electrical power.

DATES: This AD becomes effective on May 5, 2009.
On May 5, 2009, the Director of the Federal Register approved the
incorporation by reference of certain publications listed in this AD.

SUPPLEMENTARY INFORMATION:

Discussion

On January 7, 2009, 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 Aircraft, Inc. Models PA-46-350P and PA-
46R-350T airplanes. This proposal was published in the Federal Register
as a notice of proposed rulemaking (NPRM) on January 15, 2009 (74 FR
2425). The NPRM proposed to require an inspection to verify the 35-amp
and 250-amp current limiters are installed in the proper locations and
correct the installation if the current limiters are not installed in
the proper locations. The NPRM also proposed to limit operation to only
under day VFR until the current limiter installation is inspected and
corrected.

[[Page 14462]]

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 118 airplanes in the U.S.
registry.
We estimate the following costs to do the inspection:

----------------------------------------------------------------------------------------------------------------
Total cost per Total cost on
Labor cost Parts cost airplane U.S. operators
----------------------------------------------------------------------------------------------------------------
1 work-hour x $80 per hour = $80............. Not Applicable................. $80 $9,440
----------------------------------------------------------------------------------------------------------------

We estimate the following costs to do any necessary repairs that
would be required based on the results of the proposed inspection. We
have no way of determining the number of airplanes that may need this
repair:

------------------------------------------------------------------------
Total cost per
Labor cost Parts cost airplane
------------------------------------------------------------------------
1 work-hour x $80 per hour = $80. Not Applicable...... $80
------------------------------------------------------------------------

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 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-2009-0007; Directorate Identifier 2008-CE-072-AD'' in your
request.

Sec. 39.13 [Amended]

0
2. FAA amends Sec. 39.13 by adding the following new AD:

2009-07-08 Piper Aircraft, Inc.: Amendment 39-15867; Docket No. FAA-
2009-0007; Directorate Identifier 2008-CE-072-AD.

Effective Date

(a) This AD becomes effective on May 5, 2009.

Affected ADs

(b) None.

Applicability

------------------------------------------------------------------------
Models Serial Nos.
