Incident at Lethbridge, AB


1997-07-15: C-GBLB was inbound to Lethbridge with only the pilot on board, when the a/c began squawking 7600, indicating a communication failure. Edmonton ACC picked up the squawk and advised the Lethbridge FSS, which attempted unsuccessfully to talk to the pilot. The a/c landed safely at 1920Z, and as soon as the a/c was on the ground, the a/c's radio began working. The pilot later reported to the FSS that he suspects a static build-up caused the problem, because while in the air, he could only hear static on his radio and this prevented him from transmitting and receiving communication. The a/c departed Lethbridge later in the day, and the radio was working satisfactorily.
