NOAA intends to award a sole-source purchase order to Peerless-Winsmith in Springville, NY, for the repair of specific planetary gearboxes. The gearboxes are to be delivered to the National Reconditioning Center in Grandview, MO. The justification is that the OEM, Peerless-Winsmith, is the only known source authorized and capable of performing the certified repairs due to proprietary designs. Firms believing they can meet the requirements may submit substantiating documentation in writing within 15 days of the notice's publication for potential consideration. The government retains sole discretion on whether to proceed competitively.
