AGENCY
: Federal Aviation Administration (FAA), Department of Transportation (DOT).


ACTION:
 
Final rule.


–––––––––––––––––––––––––––––––––––-


SUMMARY:
 
The FAA is adopting a new airworthiness directive (AD) for certain Honeywell


International Inc., (formerly AlliedSignal, Inc., formerly Textron Lycoming, formerly Avco


Lycoming) T53 turboshaft engines, installed on, but not limited to, Bell 204, Bell 205, Kaman K-


1200 series, Bell AH-1, and Bell UH-1 helicopters, certified under 14 CFR 21.25 or 14 CFR 21.27.


This AD requires implementing reduced life limits for certain parts, using cycle counting methods,


and using draw-down schedules to replace components that exceed the new limits. This AD results


from the manufacturer informing us of test and analysis showing lower calculated service life limits


for certain parts, than previously published. We are issuing this AD to prevent failure of certain


compressor, gas producer, and power turbine rotating components, which could result in failure of the


engine and possible damage to the helicopter.


DATES:
 
This AD becomes effective February 16, 2006. The Director of the Federal Register


approved the incorporation by reference of certain publications listed in the regulations as of


February 16, 2006. The Director of the Federal Register approved the incorporation by reference of a


certain other publication listed in the regulations as of June 13, 2002 (67 FR 31111, May 9, 2002).

SUPPLEMENTARY INFORMATION:
 
The FAA proposed to amend 14 CFR part 39 with a new


AD, applicable to Honeywell International Inc., (formerly AlliedSignal, Inc., formerly Textron


Lycoming, formerly Avco Lycoming) T5309, T5311, T5313B, T5317A, T5317A-1, and T5317B


series turboshaft engines, installed on Bell 204, 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 Bell AH-1 and Bell UH-1 helicopters, certified


under 14 CFR 21.25 or 14 CFR 21.27. We published the proposed AD in the Federal Register on


June 16, 2004 (69 FR 33599). We proposed to require operators to remove from service affected


compressor, gas producer, and power turbine rotating components at reduced life limits. We also


proposed to require using draw-down schedules to replace components that exceed the new limits.


On January 6, 2005, the Federal Register (70 FR 1215) published notice that we would hold a


public meeting to gather additional comments and data on the proposed AD. We held the meeting


February 8, 2005, in Anaheim, California, at the Anaheim Convention Center. As a result of the


comments we received, we reopened the comment period for the proposed AD as found in the


Federal Register on March 14, 2005 (70 FR 12421).


Examining the AD Docket


You may examine the docket that contains the AD, any comments received, and any final


disposition in person at the Docket Management System (DMS) Docket Office between 9 a.m. and 5


p.m., Monday through Friday, except Federal holidays. The Docket Office (telephone (800) 647-


5227) is located on the plaza level of the Department of Transportation Nassif Building at the street


address stated in ADDRESSES. Comments will be available in the AD docket shortly after the DMS


receives them.


Comments


We provided the public the opportunity to participate in the development of this AD. They


provided comments during the public meeting we held in Anaheim, California on February 8, 2005,


and during the reopened comment period, which ran from March 14, 2005 to March 31, 2005. We


reopened the comment period because of some of the comments we received during the February 8th


meeting. We considered all comments we received.


Lack of Proof, Data, or Evidence of an Unsafe Condition


Twenty commenters oppose the AD as proposed, citing lack of proof, data, or evidence of an


unsafe condition. We disagree. We determined that the identified parts are likely to fail before


reaching their present life limits. These parts, therefore, present an unsafe condition. We are issuing


this AD to correct that unsafe condition. As a result we did not change the AD.


Request for Help From the Helicopter Industry


One commenter states that during the public meeting on this issue, held in Anaheim, CA, the


FAA requested that the industry step up to help the manufacturer develop data after-the-fact. In


addition, that the FAA has blindly accepted the manufacturer's unsupported safety theory, and finally,


that the FAA will still issue the proposed AD, despite the lack of supporting data.


We disagree. We requested the public provide whatever data they thought appropriate


concerning the proposed AD. After the meeting we reviewed all data we received, together with the


manufacturer's data, and determined that an unsafe condition exists or is likely to develop in the


engines noted in this AD. We concluded that the data supports the need for this AD.
