A departed Halifax for Deer Lake, reported a slight hydraulic problem. Aircraft burned off fuel and landed safely in Halifax. No assistance required. Nil TSB. Update: When landing gear retracted after take-off, #2 hydraulic engine driven pump caution light illuminated and #2 Main hydraulic pressure indication dropped to zero. Landing gear still retracted, although slower than normal. Once gear up and locked, hydraulic pressure came back up and caution light went out. Returned to Halifax as a precaution after fuel burn to max landing weight. When gear selected down, caution light again illuminated and went out after gear fully extended. Maintenance bled air from #2 hydraulic system and carried out ground checks. Hydraulic fluid quantities were sufficient and no leaks found. A test flight was conducted with no further problems. Aircraft returned to service.
