Incident at 38 NM SE High Level, Alberta (ATS operating irregularity)

Summary

1996-12-03: Little Red Air 911 a BE100 was on a flight from High Level to Fort Vermilion at FL190. They were on Edmonton Centre frequency 133.1. Seventy-five NM back from Fort Vermilion they were told to switch to 126.7, an enroute FSS frequency monitored by High Level. The customary procedure had previously been to be handed off to Edmonton Centre frequency 133.05, where descent, approach and advisories were received. The crew received no traffic advisory and assumed that they had been cleared for the approach and commenced their descent. At 18,000 feet, 54 NM back from Fort Vermilion, Little Red Air 911 broadcast their intentions on 126.7 and talked to High Level. While monitoring 126.7 they became aware of C-GNSO, a PA-31 who had requested a weather update at High Level. It was VMC with the PA-31 reporting the BE100 in sight and the BE100 had Fort Vermilion in sight. The PA31 was monitoring 134.6, another IFR frequency but had gone to 126.7 for a weather update. The BE100 crew talked to Centre after landing and were informed that there had been possibly a loss of separation. The pilot was informed that the deviation in normal radio frequency procedures was due to workload at Fort McMurray.
