Incident at Winnipeg, MB (Communication navigation surveillance/air traffic system)


1999-04-22: The crew of C-FEMA, a Cessna Citation, was inbound to Winnipeg on a medevac flight from Island Lake and were handed off from Centre to the Arrival Controller. The crew was unable to make contact with the Arrival Controller and made eight transmissions that were not answered over a period of about six minutes. The crew believed that they had experienced a communications failure and squawked 7600. They were able to contact Centre via telephone and the individual who took the call in Centre walked out on the floor of Centre to advise the Arrival Controller. At about the same time, the Arrival Controller re-established contact with C-FEMA after switching on his console radio speaker. He had switched to headphones on the console because of noise from a vaccuum cleaner and when he removed his headset, forgot to switch back to the speaker and was not hearing any transmissions. Also, the crew of C-FEMA did not switch frequencies back to Centre during this occurrence and assumed radio failure. OPI - System Safety
