14 CFR Part 39
[Docket No. 2001-NE-11-AD; Amendment 39-12977; AD 2002-25-02]
RIN 2120-AA64
Airworthiness Directives; Honeywell International Inc. TPE331-3,
-5, -6, -8, -10, and -11 Series Turboprop and TSE331-3 Series
Turboshaft Engines
AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD), that
is applicable to Honeywell International Inc. (formerly AlliedSignal
Inc., Garrett Turbine Engine Company and AiResearch Manufacturing
Company of Arizona) TPE331-3, -5, -6, -8, -10, and -11 series turboprop
and TSE331-3 series turboshaft engines. This amendment requires
removing weld repaired first stage compressor impellers from service.
This amendment is prompted by an uncontained TPE331-11U turboprop
engine failure and an in-flight shutdown due to the separation of the
first stage Ti 6-4 compressor impeller. The actions specified by this
AD are intended to prevent uncontained engine failures, in-flight
shutdowns, and secondary damage.
DATES: Effective January 21, 2003. The incorporation by reference of
certain publications listed in the regulations is approved by the
Director of the Federal Register as of January 21, 2003.
ADDRESSES: The service information referenced in this AD may be
obtained from Honeywell Engines, Systems and Services, Technical Data
Distribution, M/S 2101-201, P.O. Box 52170, Phoenix, AZ 85072-2170;
telephone: (602) 365-2493 (General Aviation), (602) 365-5535
(Commercial); fax: (602) 365-5577 (General Aviation and Commercial).
This information may be examined, by appointment, at the Federal
Aviation Administration (FAA), New England Region, Office of the
Regional Counsel, 12 New England Executive Park, Burlington, MA; or at
the Office of the Federal Register, 800 North Capitol Street, NW.,
Suite 700, Washington, DC.

Angeles Aircraft Certification Office, FAA, Transport Airplane
Directorate, 3960 Paramount Blvd., Lakewood CA 90712-4137; telephone:
(562) 627-5246; fax (562) 627-5210.
SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to include an AD that is
applicable to Honeywell International Inc. (formerly AlliedSignal Inc.,
Garrett Turbine Engine Company and AiResearch Manufacturing Company of
Arizona) TPE331-3, -5, -6, -8, -10, and -11 series turboprop and
TSE331-3 series turboshaft engines was published in the Federal
Register on July 25, 2002 (67 FR 48577). That action proposed to
require removing weld repaired first stage compressor impellers from
service, in accordance with Honeywell Alert Service Bulletin TPE331-
A72-2083, revision 1, dated May 17, 2002.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. Due consideration has been given to
the comment received.
One commenter states that paragraph (a)(3) as-written in the
proposal, implies that the 12,500 cycle limit applies only to weld
repairs that would be performed after the effective date of the AD. The
FAA agrees, and has moved the last phrase of that paragraph which
states, after the effective date of the AD, to the beginning of the
sentence, for clarity.
After careful review of the available data, including the comment
noted above, the FAA has determined that air safety and the public
interest require the adoption of the rule with the change described
previously. The FAA has determined that this change will neither
increase the economic burden on any operator nor increase the scope of
the AD.
Economic Analysis
There are approximately 2,040 engines of the affected design in the
worldwide fleet. The FAA estimates that 1,020 engines installed on
aircraft of U.S. registry would be affected by this AD. The FAA
estimates that 1,000 engines will have the required actions done during
a scheduled engine overhaul. The FAA also estimates that it would take
approximately 2 work hours per engine to do the actions during
scheduled engine overhauls and 80 work hours per engine during
unscheduled engine overhauls, and that the average labor rate is $60
per work hour. Required parts would cost approximately $9,600 per
engine to do the actions during scheduled engine overhauls and $14,600
per engine which includes consumables, during unscheduled engine
overhauls. Based on these figures, the total cost of the AD on U.S.
operators is estimated to be $10,108,000.
Regulatory Analysis
This final rule does not have federalism implications, as defined
in Executive Order 13132, because it would 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. Accordingly,
the FAA has not consulted with state authorities prior to publication
of this final rule.
For the reasons discussed above, I certify that this action (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. A final evaluation has been prepared for this action
and it is contained in the Rules Docket. A copy of it may be obtained
by contacting the Rules Docket at the location provided under the
caption ADDRESSES.
