AD 95-24-06

A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) by superseding AD 91-23-15, Amendment 39-8084 (56 FR 63631, dated December 5, 1991), which is applicable to BHT Model 206B and 206L helicopters equipped with Allison 250-C20R engines in accordance with Supplemental Type Certificate No. SH4169NM, SH4179NM, or SH4729NM was published in the Federal Register on June 7, 1993 (58 FR 31916). That action proposed to require a revision to the Limitations section of the applicable STC RFMS in accordance with Soloy Corporation Service Bulletin 02-680, revised December 8, 1992.

Interested persons have been afforded an opportunity to participate in the making of this amendment. No comments were received on the proposal or the FAA's determination of the cost to the public. The FAA has determined that air safety and the public interest require the adoption of the rule as proposed, except for some editorial changes and adding explanatory Note 1, relating to the scope of the applicability statement when modifications, alterations, or repairs have been made in the area subject to the requirements of the AD. Additionally, the FAA has revised the proposed estimated average labor rate from $55 per work hour to an estimated average labor rate of $60 per work hour in the preamble portion of this final rule. This revision will increase the estimated total cost impact of the AD from $1,045 to $1,140. Finally, the type certificate has been transferred to a new owner since the issuance of the proposal. The FAA has determined that these changes will neither increase the economic burden on any operator nor increase the scope of the AD.

The FAA estimates that 19 helicopters of U.S. registry will be affected by this AD, that it will take approximately one work hour per helicopter to accomplish the required actions, and that the average labor rate is $60 per work hour. Based on these figures, the total cost impact of the AD on U.S. operators is estimated to be $1,140.

The regulations adopted herein will not have substantial direct effects 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. Therefore, in accordance with Executive Order 12612, it is determined that this final rule does not have sufficient federalism implications to warrant the preparation of a Federalism Assessment.

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 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 from the Rules Docket at the location provided under the caption "ADDRESSES."
