RIN 2120-AA64
Airworthiness Directives; Honeywell International Inc., (Formerly
AlliedSignal, Inc., Formerly Textron Lycoming) T5309, T5311, T5313B,
T5317A, T5317A-1, and T5317B Series, and T53-L-9, T53-L-11, T53-L-13B,

Series Turboshaft Engines
AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Notice of proposed rulemaking (NPRM); reopening of the comment
period.
-----------------------------------------------------------------------
SUMMARY: The FAA is reopening the comment period of a proposed
airworthiness directive (AD) for Honeywell International Inc.,
(formerly AlliedSignal, Inc., formerly Textron Lycoming) T5309, T5311,
T5313B, T5317A, T5317A-1, and T5317B series turboshaft engines,
installed on, but not limited to, Bell 205 and Kaman K-1200 series
helicopters, and T53-L-9, T53-L-11, T53-L-13B, T53-L-13BA, T53-L-13B S/
SA, T53-L-13B S/SB, T53-L-13B/D, and T53-L-703 series turboshaft
engines, installed on, but not limited to, Bell AH-1 and UH-1
helicopters, certified under Sec. 21.25 or 21.27 of the Code of
Federal Regulations (14 CFR 21.25 or 14 CFR 21.27). The proposed AD
would require operators to remove from service affected compressor, gas
producer, and power turbine rotating components at reduced life limits,
and would require use of replacement drawdown schedules for components
on certain engine models that exceed the new limits. Since issuing the
NPRM, we have determined that the comment period for NPRM, Docket No.
FAA-2004-18038 (69 FR 33599, June 16, 2004) should be reopened and the
public should have additional time to comment.
DATES: We must receive any comments on this proposed AD by March 31,
2005.

proposed AD.

Discussion
We published a proposal to amend part 39 of the Code of Federal
Regulations (14 CFR part 39) to include an AD that would apply to
Honeywell International Inc. T5309, T5311, T5313B, T5317A, T5317A-1,
and T5317B Series, and T53-L-9, T53-L-11, T53-L-13B, T53-L-13BA, T53-L-
13B S/SA, T53-L-13B S/SB, T53-L-13B/D, and T53-L-703 series turboshaft
engines in the Federal Register as a notice of proposed rulemaking
(NPRM) on June 16, 2004 (69 FR 33599). The NPRM proposed to require
operators to remove from service affected compressor, gas producer, and
power turbine rotating components at reduced life limits, and would
require use of replacement drawdown schedules for components on certain
engine models that exceed the new limits. The NPRM resulted from
continuous analysis of field-returned hardware indicating smaller
service life margins than originally expected.
Reason for This Action
We held a public meeting on February 8, 2005, at which we received
additional data from operators of the affected engines. We determined
that we should reopen the comment period to allow an additional
opportunity for operators and other interested persons who were not
able to attend the public meeting to submit comments. We are
particularly interested in receiving comments from operators of the
affected engines as to what life limits they are using for the
components identified in the proposed AD, what cycle counting methods
they employ, what historical lifing records did they receive when they
acquired the engine, and what mission profiles are they flying.
We will address all comments in any final rule or subsequent action
taken by us on this subject. We are republishing the actual AD portion
of the NPRM, Docket No. FAA-2004-18038, for the convenience of the
owners and operators of the affected engines.
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 proposed AD would not have federalism
implications under Executive Order 13132. This proposed AD 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.
For the reasons discussed above, I certify that the proposed
regulation:
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. Would 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 proposal and
placed it in the AD Docket. You may get a copy of this summary at the
address listed under ADDRESSES.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Safety.
The Proposed Amendment
Under the authority delegated to me by the Administrator, the
Federal Aviation Administration proposes to amend 14 CFR part 39 as
follows:
PART 39--AIRWORTHINESS DIRECTIVES
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
2. The FAA amends Sec. 39.13 by adding the following new
airworthiness directive:
Honeywell International Inc., (formerly AlliedSignal, Inc., formerly
Textron Lycoming): Docket No. FAA-2004-18038; Directorate Identifier
2004-NE-01-AD.
Comments Due Date
(a) The Federal Aviation Administration (FAA) must receive
comments on this airworthiness directive (AD) action by March 31,
2005.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Honeywell International Inc., (formerly
AlliedSignal, Inc., formerly Textron Lycoming) T5309, T5311, T5313B,
T5317A, T5317A-1, and T5317B series turboshaft engines, installed
on, but not limited to, Bell 205 and Kaman K-1200 series
helicopters, and T53-L-9, T53-L-11, T53-L-13B, T53-L-13BA, T53-L-13B
S/SA, T53-L-13B S/SB, T53-L-13B/D, and T53-L-703 series turboshaft
engines, installed on, but not limited to, Bell AH-1 and UH-1
helicopters, certified under Sec. 21.25 or 21.27 of the Code of
Federal Regulations (14 CFR 21.25 or 14 CFR 21.27).
Unsafe Condition
(d) This AD results from continuous analysis of field-returned
hardware
[[Page 12423]]
indicating smaller service life margins than originally expected. We
are issuing this AD to prevent failure of compressor, gas producer,
and power turbine rotating components, which could result in an
uncontained failure of the engine and damage to the helicopter.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified unless the
actions have already been done.
