This is a sole source repair requirement for three C-130H aircraft avionics components: an Alarm Monitor, an Air Speed Indicator, and an Air Data Computer. The effort will be a Requirements type contract with a total period of performance of five years, consisting of a one-year basic period followed by four one-year ordering periods. Best estimated quantities vary by component and by ordering period, with annual quantities typically ranging from one to four units. No technical data is available for this effort.
