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 § 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.

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.

1. The authority citation for part 39 continues to read as follows:

Start Authority

Authority: 49 U.S.C. 106(g), 40113, 44701.

End Authority
[Amended]

2. The FAA amends § 39.13 by adding the following new airworthiness directive:
