AGENCY: Federal Aviation Administration, DOT.
ACTION: Final rule.
SUMMARY: This amendment revises Airworthiness Directive (AD) 96-10-01, which currently requires a complete landing light support replacement on certain The New Piper Aircraft, Inc. (Piper) Models PA-28-140, PA-28-150, PA-28-160, and PA-28-180 airplanes. Some of the serial numbers for these airplanes were incorrectly referenced in the Applicability section of AD 96-10-01. This AD maintains the requirements of AD 96-10-01, and corrects the serial numbers referenced in the Applicability section. The actions specified by this AD are intended to prevent the landing light retainer support seal from being ingested by the updraft carburetor, which could result in rough engine operation or possible engine failure and loss of control of the airplane.
The incorporation by reference of Piper Service Bulletin No. 975, dated November 2, 1994, as listed in the regulations, was previously approved by the Director of the Federal Register as of June 10, 1996 (61 FR 19813, May 3, 1996).
DATES: Effective December 14, 1998.
ADDRESSES: Service information that applies to this AD may be obtained from The New Piper Aircraft, Inc., Attn: Customer Service, 2926 Piper Drive, Vero Beach, Florida 32960. This information may also be examined at the Federal Aviation Administration (FAA), Central Region, Office of the Regional Counsel, Attention: Rules Docket No. 95-CE-51-AD, Room 1558, 601 E. 12th Street, Kansas City, Missouri 64106; or at the Office of the Federal Register, 800 North Capitol Street, NW, suite 700, Washington, DC.
FOR FURTHER INFORMATION CONTACT: William O. Herderich, Aerospace Engineer, Atlanta Aircraft Certification Office, One Crown Center, 1895 Phoenix Blvd., Suite 450, Atlanta, Georgia 30349; telephone: (770) 703-6069; facsimile: (770) 703-6097.
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 Piper Models PA-28-140, PA-28-150, PA-28-160, and PA-28-180 airplanes was published in the Federal Register as a notice of proposed rulemaking (NPRM) on June 9, 1998 (63 FR 31374). The NPRM proposed to revise AD 96-10-01 to retain the requirement of accomplishing a complete landing light support replacement, and proposed to change the applicability of the AD, as follows: Models PA-28-140 airplanes, serial numbers (S/N) 28-20000 through 28-7725290, Models PA-28-150, 160, and 180 airplanes, S/N 28-1 through 28-7505259, and S/N 28-E13 to Models PA-28-140 airplanes, S/N 28-20000 through 28-7725290, PA-28-150, PA-28-160, and PA-28-180, serial numbers 28-1 through 28-1760. Accomplishment of the proposed action as specified in the NPRM would be required in accordance with Piper Service Bulletin No. 975, dated November 2, 1994.
The NPRM was the result of inadvertent mistakes in the serial number effectivity of certain airplane models referenced in AD 96-10-01.
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.
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.
The FAA estimates that 10,100 airplanes in the U.S. registry will be affected by this AD, that it will take approximately 2 workhours per airplane to accomplish this action, and that the average labor rate is approximately $60 an hour. Parts cost approximately $140 per airplane. Based on these figures, the total cost impact of this AD on U.S. operators is estimated to be $2,626,000. This figure is based on the assumption that all of the affected airplanes have old landing light support and seal assemblies and that none of the owners/operators of the affected airplanes have replaced the landing light support and seal assemblies with parts of improved design.
Piper has informed the FAA that parts have been distributed to equip approximately 7,021 airplanes. Assuming that these distributed parts are incorporated on the affected airplanes, the cost of this AD will be reduced by $1,825,460, from $2,626,000 to $800,540.
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".
