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.
