Incident at CALGARY INTL AB (CYYC) (Weather - visibility, Conflict - potential, ATS operating irregularity)

UPDATE A10W0040: Due to the reduced visibility in freezing fog (RVR2200 for runway 16), the Calgary Airport was operating under their reduced visibility operations plan (RVOP). Runway 16 was the only active runway and there were 12 aircraft lined up for departure from the threshold, 2 from taxiway 'C4' and 1 from taxiway 'U' at mid field. After a BAE HS125, CNK744, departed from the threshold, a de Havilland DHC-8-100, NCB801, was instructed to line up and wait at the threshold of 16. NCB801 was the aircraft at taxiway 'U'. The data on the EXCDS (electronic flight strip) for NCB801 indicated a departure from 'U'. The flight crew of NCB801 queried the controller about the instruction and the recent take-off clearance for CNK744 but did not identify that they were on 'U'. The tower controller confirmed the instruction and advised NCB801 to be ready for an immediate. As NCB801 was crossing the hold line at 'U', CNK744 was overhead climbing through 500 feet. NCB801 departed from 'U' a few moments later.
Wx 1/2 SM FZFG BKN002 OVC005. Rwy 16 is active and RVOP in effect. Tower controller departed CNK744 from the threshold, rwy 16. Tower then instructed NCB801 to "line up threshold 16." NCB801 was in fact sitting at Uniform taxiway awaiting departure and read back the line up instruction. The FDE on the EXCDS did indicate NCB801 departing rwy 16 from uniform (mid-field). NCB801 queried the Tower controller if he should proceed onto the runway after hearing the take-off clearance for CNK744. The Tower controller responded in the affirmative and informed NCB801 to be prepared for the immediate due to inbound traffic. The Tower controller then departed NCB801
UPDATE TSB Edmonton has classified their investigation as a Class 3 and a Minister's Observer has been appointed.

Incident at Vancouver, BC (Fire/smoke (warning), Conflict - loss of separation)

C-GNAZ departed Vancouver airport (runway 08R) at 05:39 pdt. On initial contact with Vancouver terminal the pilot advised of smoke in the cockpit Departure controller provided assistance by providing the aircraft with vectors for a right hand visual return to runway 30. The departure controller also coordinated actions with Vancouver Tower and suspended departures, however, ABL 635 (DHC8) had already departed behind C-GNAZ heading 140. In vectoring C-GNAZ for an approach to runway 30 less than minimum separation occurred (approx. 2.4 nm) between GNAZ and ABL635. On initial contact with terminal departure ALB635 was advised of traffic and provided a vector away from GNAZ. ABL635 advised of traffic in sight. OPI: Maintenance & Manufacturng Update from TSB: A99P0131 THE PILOT OF THE HAWKER SIDDLEY HS125 (C-GNAZ) REPORTED THAT DURING CLIMB OUT FROM VANCOUVER, SMOKE HAD ENTERED THE CABIN AND IDENTIFIED THE SMOKE AS BURNING OIL. HE ADVISED THE TOWER OF HIS IMMEDIATE RETURN TO VANCOUVER. THE DEPARTURE CONTROLLER PROVIDED ASSISTANCE BY COMMUNICATING VECTORS FOR A RIGHT HAND VISUAL TO RWY30. THE DEPARTURE CONTROLLER ALSO COORDINATED ACTIONS WITH CYVR TOWER AND SUSPENDED DEPARTURES, HOWEVER ABL635 (DH8) HAD ALREADY DEPARTED BEHIND THE HS125 HEADING 140. IN VECTORING THE HS125 FOR AN APPROACH TO RUNWAY 30 LESS THAN MINIMUM SEPARATION OCCURED (APPROX 2.4NM WHERE 3NM IS REQUIRED) BETWEEN C-GNAZ AND ABL635. ON INITIAL CONTACT WITH TERMINAL DEPARTURE ABL635 WAS ADVISED OF TRAFFIC AND PROVIDED A VECTOR AWAY FROM C-GNAZ. THE DASH-8 REPORTED TRAFFIC IN SIGHT. NAV CANADA IS REVIEWING THE OCCURENCE FOR THE LOSS OF SEPARATION. AFTER LANDING WITHOUT INCIDENT THE CREW OF THE HS125 CARRIED OUT SOME FAULT FINDING ENGINE RUNS. IT WAS ESTABLISHED THE THE FAULT WAS NOT IN THE A.P.U. OR AIR CONDITIONNING SYSTEMS AND THE AIRCRAFT RETURNED TO ITS MAIN BASE. SUBSEQUENTLY, PACIFIC AERO TECH INC. CARRIED OUT EVALUATIVE GROUND RUNS, CONCLUDING THAT EXCESSIVE PRESSURE IN THE GEARCASE WAS CAUSED BY THE SEIZURE OF AN ENGINE OIL BYPASS VALVE IN THE CLOSED POSITION, ALLOWING THE OIL PRESSURE TO BUILD UP CAUSING THE CARBON LABYRINTH SEALS TO FAIL. THE ENGINE OIL, UNDER PRESSURE, MIGRATED INTO THE AIR BLEED SYSTEM, THE AIR CONDITIONNING SYSTEM AND INTO THE CABIN. THE FAILURE OF THE CARBON SEALS RENDERED THE ENGINE UNSERVICEABLE. THE ENGINE WILL BE DISASSEMBLED AND REPAIRED.
