Incident at CALGARY INTL AB (CYYC) (Aerodrome, runway or taxiway shutdown)


2001-03-26: ACA 850, an A340 with 131 people on board, departed Calgary (YYC) for London at 0141Z and shortly after takeoff, the crew reported through Terminal Control that they had a gear door problem and were returning. They carried out an overweight landing on Runway 16 at 0228Z and stopped on the runway, south of Taxiway U, to cool the brakes. ERS was on standby. ACA 850 taxied clear of Runway 16 at 0315Z. The problem was traced to a faulty gear door uplock mechanism.
2001-03-29: UPDATE TSB reported that ACA 850 experienced a right center gear door unlocked caution light after landing gear retraction. The A340 flew for approximately 40 minutes before returning to Calgary. An emergency was declared and ERS was on stand by for the landing. The A340 landed approximately 35,000 kg overweight and remained on the runway for 45 minutes as ERS crews put fans on the brakes to help cool them. Maintenance discovered that a center landing gear seal was binding and caused the door indication to show not closed. The seal was removed and the Airbus dispatched under a production permit.
