The ASR-9 radar system, a newly commissioned radar set, lost both primary and secondary radar. The controller on position was forced to revert to non radar sep to establish control and a safe flow of traffic. While system outages do occur in isolated instances within other facs, we feel that a newly commissioned system that is scheduled to be implemented in facs all over the country should enjoy an increased reliability factor. It is not known what factors contributed to the loss of primary and secondary radar on this system but frequent occurrences have been documented. I feel that this system fails much too often and that steps need to be implemented to ensure increased reliability.

Title: CTLR REPORTER COMPLAINS ABOUT INCREASE FREQ OF NEW RADAR SYSTEM OUTAGES.
Narrative: THE ASR-9 RADAR SYS, A NEWLY COMMISSIONED RADAR SET, LOST BOTH PRIMARY AND SECONDARY RADAR. THE CTLR ON POS WAS FORCED TO REVERT TO NON RADAR SEP TO ESTABLISH CTL AND A SAFE FLOW OF TFC. WHILE SYS OUTAGES DO OCCUR IN ISOLATED INSTANCES WITHIN OTHER FACS, WE FEEL THAT A NEWLY COMMISSIONED SYS THAT IS SCHEDULED TO BE IMPLEMENTED IN FACS ALL OVER THE COUNTRY SHOULD ENJOY AN INCREASED RELIABILITY FACTOR. IT IS NOT KNOWN WHAT FACTORS CONTRIBUTED TO THE LOSS OF PRIMARY AND SECONDARY RADAR ON THIS SYS BUT FREQUENT OCCURRENCES HAVE BEEN DOCUMENTED. I FEEL THAT THIS SYS FAILS MUCH TOO OFTEN AND THAT STEPS NEED TO BE IMPLEMENTED TO ENSURE INCREASED RELIABILITY.
