An IAI-1125 flight crew declared and emergency and landed safely on the long runway of a diversion airport following the loss of hydraulics during landing gear retraction after takeoff.

Narrative

While retracting the landing gear after takeoff the CAS notified us that we had major hydraulic failures. The landing gear retracted normally. As we ran our checklists we determined we needed over 10;000 FT of runway to stop the aircraft due to significantly reduced braking. We also had no nose wheel steering; no pneumatic brakes and had to use the alternate gear extension. Then the aircraft starting making screeching noises; due to past experience I know this problem has the potential to progress from a hydraulic problem to a generator/electrical problem; as well. Because I did not want to deal with no generators AND no hydraulics at night; the screeching noises and the long runway required we elected to divert to another airport which has a 12;000 FT runway and was in our immediate vicinity; as well. We took some time to run our checklists; get the gear down and solidify our game plan. The subsequent landing was uneventful. Crash crews met us and we exited the aircraft to see a thin film of hydraulic fluid down the entire tail cone of the aircraft. Aircraft was tugged to the ramp uneventfully.
