J -- OVERHAUL OF PT6A-27 ENGINES ON DEHAILLAND TWIN OTTER AIRCRAFT SOL 52WCNA006009SKS DUE 102199 POC Sharon K. Scrutchfield (816) 426-7267 ext. 231 The U.S. Department of Commerce, National Oceanic and Atmospheric Administration (NOAA), Aircraft Operations Center (AOC), MacDill AFB, Florida, intends to overhaul both PT6A-27 engines on the DeHavilland Twin Otter, FAA registration N57RF, due to approaching Time Between Overhaul (TBO). The aircraft's primary mission, as an observation platform for marine mammals, requires low level operation over salt water. The average flight lasts for a duration of five hours, hence the low engine cycles. Both engines have been on the Dallas Airmotive, Turbine Engine Monitoring Program (TEMP) since July 1994 when the time since major overhaul was 1100 hours. The work will be performed in the November 1999 time frame. Pertinent information applicable to the engines as of July 1, 1999 (Flight Log 99102) will be provided. The contractor will provide all labor, materials, equipment, special tools and facilities to overhaul the government engines to a zero time status. The government also needs to know the cost and availability of a set of overhauled exchange engines. The overhaul shall be in accordance with the Pratt & Whitney PT6A-27 overhaul manual. The contractor will replace all parts recommended by the manufacturer to be replaced at each overhaul regardless of their apparent condition, this includes, but is not limited to gaskets, packing, rubber parts, lockwashers, tablocks, etc. Only approved parts are to be used. The Government and/or the contractor will remove the engines from the aircraft at the Aircraft Operations Center (AOC) on MacDill Air Force Base, Tampa, Florida. The Government may elect to have the Contractor remove and reinstall the engines at their overhaul facility. The Contractor overhauling the engines will be responsible for shipping two PT6A-27 engine crates to the aircraft location, and paying the freight for shipment to and from the overhaul facility. Once the engines have been disassembled at the overhaul facility the Contractor will provide the Government a tear down inspection report thatincludes the extent of the inspection, condition found of all major components, outstanding service bulletins and airworthiness directives that must be complied with, and any recommendations for the prevention of further failures if applicable. Once the overhaul is complete the Contractor will run the engines on a test cell prior to reinstalling them on the aircraft. The Contractor will be responsible for all FAA and AOC required documentation. Offerors will be asked to provide a firm fixed price for tear down inspection, overhaul and known replacement parts, and run on a test cell prior to installation. Any life limited part or component that has not reached its recommended service life, but fails inspection and needs to be replaced will be treated as an over and above. Since the Government can not determine which parts or components if any meet this criteria, offerors will be asked to provide their labor rate charge per hour for over and above discrepancies. Secondly, offerors will be asked to provide whatpercent discount off list price for replacement parts both new and overhauled. PMA parts are acceptable. This acquisition is a 100% Small Business Set-Aside. Standard Industrial Classification Code 7699 applies. This acquisition is being conducted as a simplified acquisition under the authority of FAR Part 13. The solicitation will be issued on or about October 7, 1999.
