AD 95-23-12

A proposal to amend part 39 of the Federal Aviation Regulations (14 CFR part 39) to include an AD that would apply to Piper Model PA-46-350P airplanes was published in the Federal Register on June 5, 1995 (60 FR 29511). The action proposed installing a placard (to the right of the manifold pressure gauge in full view of the pilot) that specifies manifold pressure limits. The proposed action would also require incorporating revised page 2-16 (dated March 29, 1995) of Revision 14 (PR950329) to Report: VB-1332 into the Limitations Section of the PA-46-350P POH. Piper Service Bulletin (SB) No. 982, dated April 3, 1995, contains the placard, and instructions on installing the placard and incorporating the POH revision. The proposed AD will allow an owner/operator who holds a private pilot's certificate as authorized by sections 43.7 and 43.11 of the Federal Aviation Regulations (14 CFR 43.7 and 43.11) to perform these actions.

Interested persons have been afforded an opportunity to participate in the making of this amendment. No comments were received on the proposed rule or the FAA's determination of the cost to the public.

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.

The compliance time of this AD is presented in calendar time instead of hours time-in-service (TIS). Although the unsafe condition can develop as a result of airplane usage, it cannot develop unless the manifold pressure limits specified in the required action are exceeded. Therefore, to ensure that all owners/operators of the affected airplanes incorporate the manifold pressure limits in a reasonable amount of time, a compliance based on calendar time is utilized.

The FAA estimates that 189 airplanes in the U.S. registry will be affected by this AD and that it will take approximately 1 workhour per airplane to accomplish the required action. Since an owner/operator who holds a private pilot's certificate as authorized by sections 43.7 and 43.11 of the Federal Aviation Regulations (14 CFR 43.7 and 43.11) can accomplish this action, the only impact this action would have upon the public is the time it takes each owner/operator to install the placard and incorporate the POH revision. Accomplishment of the required action would be in accordance with Piper SB No. 982, dated April 3, 1995, which contains the placard, and instructions on installing the placard and incorporating the POH revision.

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 copy of the final evaluation prepared for this action is contained in the Rules Docket. A copy of it may be obtained by contacting the Rules Docket at the location provided under the caption "ADDRESSES".
