UPDATE: TSB Report #A21F0226: C-GWYB, a DBA Novajet Learjet 45 was conducting a flight between Fort Myers/Page Field, FL (KFMY) and Kitchener/Region of Waterloo Intl, ON (CYKF). During initial cruise, the crew noticed a slow but steady decrease in cabin temperature. An attempt was made to increase the cabin temperature in both manual and automatic modes until the crew adjustments had no more effects. During descent, approximately 110 nm south of CYKF, power was reduced and abrupt HP bleed cycling was observed. Descending through FL330, the crew started to notice the smell of hot synthetic oil. Shortly thereafter, passengers alerted the crew that smoke was visible in the aft cabin. Temperature selectors were moved to cold, but this had no effect on temperature or smoke. The crew donned oxygen masks, completed the appropriate checklists and discussed en route alternates, but the smoke had diminished. The flight crew asked Cleveland ATC for further descent, explaining the presence of smoke but not declaring an emergency. ATC declared an emergency on behalf of the crew and provided a direct routing to the destination airport. The flight landed at CYKF without further incident. The crew did smell cyclical oil scents, which was a possible indication of an ECU oil leak. Maintenance is troubleshooting.

At approximately 100 nm SE of CYWG, FDX134 requested a descent from flight level 380 and was cleared to flight level 290 by Winnipeg Centre Area Control Centre (ACC). FDX134 subsequently started the descent. ACC then cleared B-2094, a Boeing 777-FFT operated by Air China Cargo as flight CAO1054 at flight 330, to turn right 10 degrees to provide separation with FDX134. As FDX134 was descending through flight level 340, the crew of FDX134 asked ACC about traffic ahead of them. During the radio transmission regarding the traffic, FDX134 received a TCAS TA/RA to climb. FDX134 complied with the TA/RA, notified ACC of the manoeuvre and advised once clear from the traffic. FDX134 continued for an uneventful landing at CYWG. Review of the available radar information indicates that the nearest distance between the two aircraft was 5.1 miles laterally and 600 feet vertically. Minimum separation requirements are 5 miles or 1000 feet.
