Incident at WINNIPEG / JAMES ARMSTRONG RICHARDSON INTL MB (CYWG)

Summary

2003-06-06: UPDATE TSB reported that the crew of Zip Air, Boeing 737-217, C-GCPP, rejected takeoff at 20 knots on Runway 31 at the Winnipeg International Airport due to an overheat indication. The aircraft was taxied back to the ramp for maintenance consultation. The same aircraft had been involved in two other occurrences eventually being traced to the same root problem. The first occurrence happened 2 days prior on 31 May 03 while operating as WZP 6283 (CADORS 2003C0686). The aircraft was en route from London, Ontario to Calgary when the aircraft reported an air-conditioning (overheat) problem (and an unrelated auto pilot problem) necessitating a diversion to Winnipeg. No emergency was declared and AFF was not required. The second occurrence happened on 01 June 03 when the crew rejected takeoff at the Winnipeg International Airport due to an overheat indication. The aircraft was operating as WZP 6341 and was destined for Saskatoon. After the most recent occurrence on 02 June 03, the aircraft was removed from service. Maintenance personnel eventually traced the problem to an indication fault caused by a faulty left wing body overheat loop. The loop was replaced and the aircraft was returned to service with no reported recurrence of the problem.
2003-06-05: UPDATE Maintenance and Manufacturing reported that this was actually the same aircraft as in a previous occurrence this week (CADORS 2003C0686). After the first occurrence, there was extensive troubleshooting of the system and company maintenance could not duplicate the problem, so the aircraft was eventually dispatched with an MEL. This was when the warning occurred again and it only occurred once the aircraft got up to a little bit of speed. At this point, the aircraft was grounded for more troubleshooting. Maintenance eventually replaced a pack overheat loop, which has cured the problem.
2003-06-03: The crew of WZP 6261, a B737-200, rejected their takeoff on Runway 31 at Winnipeg due to an 'overheat' indication. No other aircraft were inconvenienced. TSB will contact the company.
