14 CFR Part 39
[Docket No. FAA-2009-0555; Directorate Identifier 2009-NE-18-AD;
Amendment 39-15996; AD 2009-17-05]
RIN 2120-AA64
Airworthiness Directives; Honeywell International Inc. TPE331-10
and TPE331-11 Series Turboprop Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule; request for comments.
-----------------------------------------------------------------------
SUMMARY: The FAA is adopting a new airworthiness directive (AD) for
Honeywell International Inc. TPE331-10 and TPE331-11 series turboprop
engines. This AD requires removing certain first stage turbine disks
from service. This AD results from a report of an uncontained failure
of a first stage turbine disk that had a metallurgical defect. We are
issuing this AD to prevent uncontained failure of the first stage
turbine disk and damage to the airplane.
DATES: This AD becomes effective September 1, 2009. We must receive any
comments on this AD by October 16, 2009.
ADDRESSES: Use one of the following addresses to comment on this AD:

Angeles Aircraft Certification Office, FAA, Transport Airplane
Directorate, 3960 Paramount Blvd., Lakewood, CA 90712-4137; e-mail:

SUPPLEMENTARY INFORMATION: In May 2008, we received a report of an
uncontained separation of a first stage turbine disk, part number (P/N)
3107079-1. The disk was installed in a TPE331-11U turboprop engine.
That disk, which has a 20,000-cycle life, failed after accumulating
8,314 cycles-in-service. The fracture revealed a large melt-related
oxide cluster inclusion in the web area of the disk, which occurred
during the forging alloy melting process. The disk was produced from
Waspaloy material, from Heat Lot 9-7121, which was melted by Special
Metals in 1980. We have determined that five turbine disks that were
next to the failed disk during the billet-forging process may also
contain part of the same melt-related oxide cluster inclusion. This
condition, if not corrected, could result in uncontained failure of the
first stage turbine disks made from these billets and damage to the
airplane.
FAA's Determination and Requirements of This AD
The unsafe condition described previously is likely to exist or
develop on other Honeywell International Inc. TPE331-10 and TPE331-11
series turboprop engines of the same type design with the affected
first stage turbine disks installed. For that reason, we are issuing
this AD to prevent uncontained failure of the first stage turbine disk
and damage to the airplane. This AD requires removal from service of
first stage turbine disks, P/Ns 3101520-1 and 3107079-1, serial numbers
2-03501-2299, 2-03501-2300, 2-03501-2301, 2-03501-2302, and 2-03501-
2304, within 25 flight hours or 25 cycles-in-service after the
effective date of this AD, whichever occurs first.
FAA's Determination of the Effective Date
Since an unsafe condition exists that requires the immediate
adoption of this AD, we have found that notice and opportunity for
public comment before issuing this AD 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 us any written relevant data,
views, or arguments regarding this AD. Send your comments to an address
listed under ADDRESSES. Include ``AD Docket No. FAA-2009-0555;
Directorate Identifier 2009-NE-18-AD'' in the subject line of your
comments. We specifically invite comments on the overall regulatory,
economic, environmental, and energy aspects of the rule that might
suggest a need to modify it.
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
with FAA personnel concerning this AD. Using the search function of the
Web site, anyone can find and read the comments in any of our dockets,
including, if provided, the name of the individual who sent the comment
(or signed the comment on behalf of an association, business, labor
union, etc.). You may review the DOT's complete Privacy Act Statement
in the Federal Register published on April 11, 2000 (65 FR 19477-78).
Examining the AD Docket
You may examine the AD docket on the Internet at http://www.regulations.gov; or in person at the Docket Operations office
between 9 a.m. and 5 p.m., Monday through Friday, except Federal
holidays. The AD docket contains this AD, the regulatory evaluation,
any comments received, and other information. The street address for
the Docket Operations office (telephone (800) 647-5527) is the same as
the Mail address provided in the ADDRESSES section. Comments will be
available in the AD docket shortly after receipt.

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 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
placed it in the AD Docket. You may get a copy of this summary at the
address listed under ADDRESSES.
