Narrative:

Departed st kitt island en route to teb. Climbing through FL330 the aircraft experienced a combined hydraulic failure. We diverted to tjsj, approximately 45 mi away. Ran all checklists, combined hydraulic checklist several times. Was vectored for a visual approach to runway 10 at tjsj. We requested runway 8 (the long runway) and received landing clearance for runway 8. Emergency gear extension checklist was used and gear extended. The approach was 'no flaps.' touchdown was uneventful. When nose gear touched runway, brake peddles were depressed. No braking action occurred. Due to loss of nosewheel steering, the single thrust reverser was not deployed. The emergency brake handle was used. The aircraft stopped on hard surface -- well short of runway end. There was damage to the inboard flaps and gear doors due to failure of all 4 main tires. There were no injuries, no other damage.

Title: GLF-4 CREW HAD HYD SYS FAILURE AND DIVERTED TO THE NEAREST SUITABLE ARPT. THE ACFT WAS DAMAGED ON LNDG WHEN THE MAIN GEAR TIRES BLEW WITH USE OF THE EMER BRAKE SYS.

Narrative: DEPARTED ST KITT ISLAND ENRTE TO TEB. CLBING THROUGH FL330 THE ACFT EXPERIENCED A COMBINED HYD FAILURE. WE DIVERTED TO TJSJ, APPROX 45 MI AWAY. RAN ALL CHKLISTS, COMBINED HYD CHKLIST SEVERAL TIMES. WAS VECTORED FOR A VISUAL APCH TO RWY 10 AT TJSJ. WE REQUESTED RWY 8 (THE LONG RWY) AND RECEIVED LNDG CLRNC FOR RWY 8. EMER GEAR EXTENSION CHKLIST WAS USED AND GEAR EXTENDED. THE APCH WAS 'NO FLAPS.' TOUCHDOWN WAS UNEVENTFUL. WHEN NOSE GEAR TOUCHED RWY, BRAKE PEDDLES WERE DEPRESSED. NO BRAKING ACTION OCCURRED. DUE TO LOSS OF NOSEWHEEL STEERING, THE SINGLE THRUST REVERSER WAS NOT DEPLOYED. THE EMER BRAKE HANDLE WAS USED. THE ACFT STOPPED ON HARD SURFACE -- WELL SHORT OF RWY END. THERE WAS DAMAGE TO THE INBOARD FLAPS AND GEAR DOORS DUE TO FAILURE OF ALL 4 MAIN TIRES. THERE WERE NO INJURIES, NO OTHER DAMAGE.
