Narrative:

En route over cleveland, lost all hydraulic system #2 fluid. This resulted only in loss of partial ground lift dumping and inboard brakes. Per QRH, diverted to cmh. By the time we got hydraulic low caution, fluid was already gone. Cmh was decided to be diversion when factoring in descent. Several leaks were found in hydraulic system #2. Perhaps accumulator on all hydraulic controls would allow extra use of system that are dependent on one system.

Title: A CANADAIR CL65 IN CRUISE AT FL280 DIVERTED DUE TO LOSS OF #2 HYD SYS CAUSED BY SEVERAL LEAKS.

Narrative: ENRTE OVER CLEVELAND, LOST ALL HYD SYS #2 FLUID. THIS RESULTED ONLY IN LOSS OF PARTIAL GND LIFT DUMPING AND INBOARD BRAKES. PER QRH, DIVERTED TO CMH. BY THE TIME WE GOT HYD LOW CAUTION, FLUID WAS ALREADY GONE. CMH WAS DECIDED TO BE DIVERSION WHEN FACTORING IN DSCNT. SEVERAL LEAKS WERE FOUND IN HYD SYS #2. PERHAPS ACCUMULATOR ON ALL HYD CTLS WOULD ALLOW EXTRA USE OF SYS THAT ARE DEPENDENT ON ONE SYS.
