The aircraft returned to the gate and was examined by maintenance staff, who determined that the right IDG was almost out of oil. The oil was replenished, a runup was completed, and the flight departed without further incident. The operator has recently reduced inspection times for its integrated drive generators in response to a pattern of abnormally high oil consumption.
AWI 543, a Canadair RJ, was departing on Runway 36 at Winnipeg for Denver when the crew rejected the takeoff due to a generator warning. The crew taxied the aircraft back to the threshold and attempted a second takeoff, which was also rejected for the same reason. They taxied back to the apron. No other aircraft were affected.

April 21, 2003

Incident at WINNIPEG / JAMES ARMSTRONG RICHARDSON INTL MB (CYWG) (Aerodrome - visual aids)

UPDATE TSB reported that the pilot of the Diamond Katana, C-FGAI operated by Flying Colors Pilot Training, had been cleared to taxi for night circuits via Golf Taxiway and Runway 07, to hold short of Runway 36. The aerodrome lighting had been turned on by the Tower Controllers within the previous 90 minutes, with the exception of the edge lights on the portion of Runway 07 west of Runway 36. This portion of Runway 07 is no longer used for takeoff or landing and is equipped with blue taxiway lights. It could not be determined why these lights were not turned on. The lighting was not on for the holding position signs on the west side of the Runway 07/25 and 18/36 intersection because they are powered from the taxiway lighting circuit for the west end of Runway 07. The pilot of C-FGAI did not see the unlighted holding position signs, and also did not see the yellow holding position markings on the pavement. As the pilot of C-FGAI continued taxiing eastward, she looked to the right and saw the landing lights of a Canadair RJ, N437AW operated by Air Wisconsin as flight AWI 542, and realized she was on Runway 18/36. She opened the throttle and continued taxiing straight ahead and cleared the runway before AWI 542 crossed the intersection on its landing roll. Aerodrome Safety is monitoring the lighting issue.
The Privately-licenced pilot of C-FGAI, a Diamond DA-20, was taxiing for a night departure on Runway 36 from the Runway 07 intersection at Winnipeg International Airport. The pilot inadvertently taxied onto Runway 36 without clearance when AW 1542, a Canadair RJ, was on short final to Runway 36. The pilot then was advised of the situation and taxied off the runway. The FTU was aware of the incident and has responded with extra training for the pilot including oral counselling and a training flight. In addition, the manager of the FTU will brief all of his instructors on proper procedures for holding short of runways.
UPDATE Aerodrome Safety reported that the first part of Runway 07, which begins at the junction of Runway 13/31 and ends at the junction of Runway 18/36, and is used as a taxiway, was unlighted at the time of the occurrence. Further to this, the runway identification lights were not on since they are on the same electrical circuit. The lighting system for Runway/Taxiway 07/25 was checked about 24 hours after the event and functioned normally. Aerodrome Safety has requested that it be placed as an agenda item at Aerodrome Safety national meeting in May. The question is, should runway hold or identification lights be on the same circuit as the taxiway lights or the runway lights? The Manager of the FTU was aware of the lighting issue and had been so informed by the pilot. He indicated that had the lights been turned on, it might have aided the pilot, but he also noted that she had taxied along that route many times and was familiar with the taxiway and where the hold line and intersection were located. He believes that the pilot was simply not paying attention during the taxi and had she been doing so, the incursion would not have occurred.

March 9, 2003

Incident at EDMONTON INTL AB (CYEG)

AWI 870, a Canadair RJ, departed Edmonton for Denver, and when the flight was 50 NM southwest of YEG, the crew advised Edmonton ACC of an unsafe door indication and would be returning. The aircraft landed safely at 1515Z.
