AD 97-15-13 R2

Events Leading to the Issuance of This AD A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to certain Raytheon Beech Models 1900, 1900C, and 1900D airplanes was published in the Federal Register as a notice of proposed rulemaking (NPRM) on October 9, 1998 (63 FR 54393). The NPRM proposed to revise AD 97-15-13 R1, Amendment 39-10131 (62 FR 49426, September 22, 1997), by incorporating updated service information into the AD. AD 97-15-13 R1 currently requires installing lubrication fittings in the airstair door handle and latch housing mechanisms on certain Raytheon Beech Models 1900, 1900C, and 1900D airplanes.

Accomplishment of the actions of AD 97-15-13 R1 is required in accordance with Raytheon Mandatory Service Bulletin No. 2572, Issued: July, 1996.

Accomplishment of the proposed installations would be required in accordance with Raytheon Mandatory Service Bulletin No. 2572,Issued: July, 1996; or Raytheon Mandatory Service Bulletin SB.2572, Issued: July, 1996; Revision No. 1, May, 1998.

Interested persons have been afforded an opportunity to participate in the making of this amendment. One comment was received in favor of the NPRM and no comments were received on the FAA's determination of the cost to the public.

The FAA's Determination After careful review of all available information related to the subject presented above, the FAA has determined that air safety and the public interest require the adoption of the rule as proposed except for minor editorial corrections. The FAA has determined that these minor corrections will not change the meaning of the AD and will not add any additional burden upon the public than was already proposed.

Cost Impact The FAA estimates that 408 airplanes in the U.S. registry will be affected by this AD, that it will take approximately 14 workhours per airplane to accomplish the installation, and thatthe average labor rate is approximately $60 an hour. Parts cost approximately $50 per airplane. Based on these figures, the total cost impact of this AD on U.S. operators is estimated to be $363,120, or $890 per airplane. This figure is based on the presumption that no owner/operator of the affected airplanes has accomplished the required installation.

This AD requires the same actions as AD 97-15-13 R1. The only difference is reference to Raytheon Mandatory Service Bulletin SB.2572, Issued: July, 1996; Revision No. 1, May, 1998. Therefore, this AD imposes no additional cost impact upon U.S. owners/operators of the affected airplanes than is already required by AD 97-15-13 R1. Regulatory Impact

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 withExecutive 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 copy of the final evaluation prepared for this action is contained in the Rules Docket.
