Incident at 60 NM E of Calgary, AB

Summary

1999-09-21: CDN 901, a B737, was 60 miles east of Calgary on a scheduled flight from Ottawa when the crew advised that the a/c had experienced a hydraulic failure. They declared an emergency and were given priority. The flight landed safely at Calgary at 1650Z with CFR on standby. There was minimal effect on operations. OPI - System Safety UPDATE TSB reported that the "A" system failed because of a malfunctioning air pressure regulator. This provides a head of pressure to the hydraulic system so that the hydraulic pump does not cavitate. The loss of pressure resulted in pump cavitation.
