Incident at THOMPSON MB (CYTH) (Aerodrome - power failure, ATM - other, ATM - NAVAIDS/radar)

Summary

2003-01-13: At 2253Z, a complete power failure occurred at the Thompson airport for a duration of 5-10 seconds, followed by a second complete power failure for approximately one second at 2304Z. Two aircraft inbound to Thompson reported receiving signals on all facilities except the YTH VOR (112.9). Thompson FSS was unable to monitor RVR RWY 05, GP05, and DME CH 40. Winnipeg TOC was advised of the above and issued Notams for the RVR RWY 05 and GP05 indicating them unserviceable. Also the DME CH 40 was Notamed unmonitored. All Notams were until 03/01/13/2300Z. YTH VOR was voice Notamed unserviceable until 0015Z. TOC advised the YTH VOR became serviceable at 2353Z.
2003-01-14: UPDATE ANS and Airspace reported that the problem was caused by a 'bump' in the power supply from Manitoba Hydro. This caused the monitoring equipment to 'hang up' so that it was not performing it's function to monitor. Thus, all affected equipment had to be NOTAMed as such until the technicians could manually inspect the equipment and restore the monitors to operation.
