AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule; request for comments.

SUMMARY: We are adopting a new airworthiness directive (AD) for Cessna
206, 207, and 210 airplanes with Hartzell Engine Technologies (HET)
turbochargers, part numbers (P/Ns) 406610-0005 and 406610-9005,
installed. This emergency AD was sent previously to all known U.S.
owners and operators of these airplanes. This AD requires removing the
affected turbochargers from service before further flight. This AD was
prompted by a report of an HET turbocharger causing an engine in-flight
power rollback. We are issuing this AD to prevent turbocharger bearing
seizure, failed turbocharger components, and damage to the airplane.

DATES: This AD is effective June 26, 2012 to all persons except those
persons to whom it was made immediately effective by Emergency AD 2012-
10-52, issued on May 14, 2012, which contained the requirements of this
amendment.
The Director of the Federal Register approved the incorporation by
reference of a certain publication identified in the AD as of June 26,
2012.
We must receive comments on this AD by July 26, 2012.

ADDRESSES: You may send comments, using the procedures found in 14 CFR
11.43 and 11.45, by any of the following methods:

SUPPLEMENTARY INFORMATION:

Discussion

On May 14, 2012, we issued Emergency AD 2012-10-52, which requires
removing HET turbochargers, P/Ns 406610-0005 and 406610-9005, before
further flight. This action was prompted by a report of an HET
turbocharger causing an engine in-flight power rollback. Upon
investigation, the turbocharger was found to have incorrectly located
oil passages in the center housing, causing insufficient oil flow to
the bearings. This condition, if not corrected, could result in
turbocharger bearing seizure, failure of the turbocharger turbine shaft
or wheel, and damage to the airplane.

Relevant Service Information

We reviewed Hartzell Engine Technologies Alert Service Bulletin
(ASB) No. 047, dated May 8, 2012. The ASB indentifies the part numbers
and serial numbers of affected turbochargers and describes procedures
for removing them from service.

FAA's Determination

We are issuing this AD because we evaluated all the relevant
information and determined the unsafe condition described previously is
likely to exist or develop in other turbochargers of the same design.
We are evaluating whether the affected population needs to expand to
include supplemental type certificate and parts manufacturer approval
installations and may take further action.

AD Requirements

This AD requires removing the affected turbochargers from service
before further flight.

Minor Clarification

In the previously sent emergency AD, applicability paragraph (c)(2)
inadvertently stated ``Turbochargers with P/N 406610-0005 or P/N
406610-9005 overhauled or repaired on or later than January 1, 2012,
with the same turbocharger center housing P/N and date code H-0112.''
That paragraph in this AD is clarified to state ``Turbochargers with P/
N 406610-0005 or P/N 406610-9005 overhauled or repaired on or later
than January 1, 2012, with turbocharger center housing P/N 409836-0005
and date code H-0112.'' Applicability paragraph (c)(3) of the
previously sent emergency AD, referenced this same turbocharger center
housing P/N, which also needs to be referenced in paragraph (c)(2).

FAA's Determination of the Effective Date

An unsafe condition exists that requires the immediate adoption of
this AD. The FAA has found that the risk to the flying public justifies
waiving notice and comment prior to adoption of this rule because the
affected turbochargers need to be removed from service before further
flight. Therefore, we find that notice and opportunity for prior public
comment are impracticable and that good cause exists for making this
amendment effective in less than 30 days.

Comments Invited

This AD is a final rule that involves requirements affecting flight
safety and was not preceded by notice and an opportunity for public
comment. However, we invite you to send any written data, views, or
arguments about this AD. Send your comments to an address listed under
the ADDRESSES section. Include the docket number FAA-2012-0565 and
Directorate Identifier 2012-NE-16-AD at the beginning of your comments.
We specifically invite comments on the overall regulatory, economic,
environmental, and energy aspects of this AD. We will consider all
comments received by the closing date and may amend this AD because of
those comments.
We will post all comments we receive, without change, to http://www.
regulations.gov, including any personal information you provide. We
will also post a report summarizing each substantive verbal contact we
receive about this AD.

Costs of Compliance

We estimate that this AD affects 80 airplanes of U.S. registry with
affected turbochargers installed. We also estimate that it will take
about 4 work-hours to remove a turbocharger from service. The average
labor rate is $85 per work-hour. Based on these figures, we estimate
the total cost of the AD to U.S. operators to be $27,200.

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

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.
