[Federal Register Volume 62, Number 18 (Tuesday, January 28, 1997)] [Rules and Regulations] [Pages 4003-4004] From the Federal Register Online via the Government Publishing Office [www.gpo.gov] [FR Doc No: 97-1964] ----------------------------------------------------------------------- DEPARTMENT OF TRANSPORTATION 14 CFR Part 39 [Docket No. 96-CE-43-AD; Amendment 39-9907; AD 97-03-01] RIN 2120-AA64 Airworthiness Directives; Raytheon Aircraft Company (Formerly Beech Aircraft Corporation) Model 1900D Airplanes AGENCY: Federal Aviation Administration, DOT. ACTION: Final rule. ----------------------------------------------------------------------- SUMMARY: This amendment adopts a new airworthiness directive (AD) that applies to certain Raytheon Aircraft Company (Raytheon) Model 1900D airplanes (formerly referred to as Beech Model 1900D airplanes). This action requires replacing the right-hand exhaust stack for both the left and right engines. This action results from reports of wing skin damage (with associated fuel seepage) and cabin window damage caused by the heat of the right-hand exhaust stacks on the affected airplanes. The actions specified by this AD are intended to prevent wing skin de- bonding or warping of the cabin windows because of the heat generated by the engines' right-hand exhaust stacks. DATES: Effective March 14, 1997. The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of March 14, 1997. ADDRESSES: Service information that applies to this AD may be obtained from the Raytheon Aircraft Company, P.O. Box 85, Wichita, Kansas 67201- 0085. This information may also be examined at the Federal Aviation Administration (FAA), Central Region, Office of the Assistant Chief Counsel, Attention: Rules Docket No. 96-CE-43-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: Mr. Karl Schletzbaum, Aerospace Safety Engineer, FAA, Wichita Aircraft Certification Office, 1801 Airport Road, Mid-Continent Airport, Wichita, Kansas 67209; telephone (316) 946-4146; facsimile (316) 946-4407. SUPPLEMENTARY INFORMATION: Events Leading to 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 Model 1900D airplanes (formerly referred to as Beech Model 1900D airplanes) was published in the Federal Register on September 30, 1996 (61 FR 51060). The action proposed to require replacing the right-hand exhaust stack for both the left and right engines. Accomplishment of the proposed replacement as specified in the notice of proposed rulemaking (NPRM) would be in accordance with the INSTALLATION INSTRUCTIONS to Raytheon Kit No. 129-9013-1, as referenced in Raytheon Mandatory Service Bulletin No. 2686, dated June 1996. The NPRM resulted from reports of wing skin damage (with associated fuel seepage) and cabin window damage on the affected airplanes, which was determined to be caused by the heat of the right-hand exhaust stacks. 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. Cost Impact The FAA estimates that 199 airplanes in the U.S. registry will be affected by this AD, that it will take approximately [[Page 4004]] 10 workhours per airplane to accomplish the required action, and that the average labor rate is approximately $60 an hour. Parts will be provided at no cost to the owners/operators of the affected airplanes until June 1997 (after that the cost will be $6,452). Based on these figures and utilizing the assumption that all owners/operators of the affected airplanes will obtain parts prior to June 1997, the total cost impact of the AD on U.S. operators is estimated to be $119,400. This figure is based upon the assumption that no affected airplane owner/ operator has already accomplished this action. 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 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.
