Narrative:

At 14000, left hydraulic pressure began a slow drop. Checklist called for left pump off. Left system pressure restored through use of standby and alternate hydraulic pumps. Since quantities and pressures were normal, no emergency was declared. Returned to pit (point of departure) and landed uneventfully.
