UPDATE: Aviation Incident Report: The crew of a Novajet Learjet 45 (C-GWYB/NOJ45) from Page Field, FL (KFMY) to Kitchener/Waterloo, ON (CYKF) decided to continue to CYKF after declaring an emergency due to smoke in the cockpit. The crew was on supplemental oxygen. Landed without further incident.
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.
