A British Airways Boeing 747-400, registration G-CIVP performing flight BA-85 from London Heathrow,EN (UK) to Vancouver,BC (Canada) with 315 people on board, was enroute at FL380 just about to reach the top of descent into Vancouver, when the crew informed ATC of a developing possible hydraulic problem due to the progressive loss of fluid from the #1 hydraulic system. The aircraft was on approach to Vancouver's runway 08L when the crew extended the flaps to 20 degrees when the #1 hydraulic system pressure began to drop and the crew prepared for total loss of hydraulic pressure on the system. The crew worked the related checklists, performed an alternate gear extension and configured the flaps using the alternate system, too. When the system failed, the crew declared emergency, emergency services assumed their standby positions for the arrival. The aircraft landed safely on Vancouver's runway 08L about 35 minutes after leaving FL380 and stopped on the runway. The aircraft was towed to the apron.

The runway remained closed for about 30 minutes after landing.

The Canadian TSB reported a major hydraulic leak was discovered in engine pylon #1 (outboard left).
