Narrative:

On feb/thu/01 at approximately XA00 hours, I was acting as PIC on hawker ferrying from hpn to pbi. On descent/approach performing the approach checklist, I observed that we only had 2200 psi on the hydraulic pressure gauge instead of the required 3000 psi. I attempted raising the spoilers, but got no response. I requested flaps 15 degrees. The indicator showed movement to 7 degrees, and did so very slowly. I explained the situation to the first officer and told him we will not be landing with flaps and reviewed the new reference speeds. After turning final runway 13, I requested gear down. There was no response -- only the 3 red unsafe lights. I told my first officer 'we will leave the airport environment and perform the necessary checklists.' he called the tower, requested radar vectors to attempt to remedy the situation. We flew west at 2500 ft MSL and carried out the emergency gear extension checklist and ensured by overflying the tower (twice) thereafter at 400 ft that there was a visual on the gear. I explained to the first officer what we would be doing in detail, came back around, and joined a left base to land on runway 13. I told the first officer to declare an emergency and let him (the tower) know our intentions. I landed the aircraft without incident and taxied to the FBO. After shutting down, I put the gear pins in and ensured the necessary persons and auths were notified.

Title: A NO FLAP LNDG IS PERFORMED AFTER AN EMER LOWERING OF THE GEAR ON A HS125-600 WHEN THE ACFT LOSES HYD PRESSURE PRIOR TO LNDG AT PBI, FL.

Narrative: ON FEB/THU/01 AT APPROX XA00 HRS, I WAS ACTING AS PIC ON HAWKER FERRYING FROM HPN TO PBI. ON DSCNT/APCH PERFORMING THE APCH CHKLIST, I OBSERVED THAT WE ONLY HAD 2200 PSI ON THE HYD PRESSURE GAUGE INSTEAD OF THE REQUIRED 3000 PSI. I ATTEMPTED RAISING THE SPOILERS, BUT GOT NO RESPONSE. I REQUESTED FLAPS 15 DEGS. THE INDICATOR SHOWED MOVEMENT TO 7 DEGS, AND DID SO VERY SLOWLY. I EXPLAINED THE SIT TO THE FO AND TOLD HIM WE WILL NOT BE LNDG WITH FLAPS AND REVIEWED THE NEW REF SPDS. AFTER TURNING FINAL RWY 13, I REQUESTED GEAR DOWN. THERE WAS NO RESPONSE -- ONLY THE 3 RED UNSAFE LIGHTS. I TOLD MY FO 'WE WILL LEAVE THE ARPT ENVIRONMENT AND PERFORM THE NECESSARY CHKLISTS.' HE CALLED THE TWR, REQUESTED RADAR VECTORS TO ATTEMPT TO REMEDY THE SIT. WE FLEW W AT 2500 FT MSL AND CARRIED OUT THE EMER GEAR EXTENSION CHKLIST AND ENSURED BY OVERFLYING THE TWR (TWICE) THEREAFTER AT 400 FT THAT THERE WAS A VISUAL ON THE GEAR. I EXPLAINED TO THE FO WHAT WE WOULD BE DOING IN DETAIL, CAME BACK AROUND, AND JOINED A L BASE TO LAND ON RWY 13. I TOLD THE FO TO DECLARE AN EMER AND LET HIM (THE TWR) KNOW OUR INTENTIONS. I LANDED THE ACFT WITHOUT INCIDENT AND TAXIED TO THE FBO. AFTER SHUTTING DOWN, I PUT THE GEAR PINS IN AND ENSURED THE NECESSARY PERSONS AND AUTHS WERE NOTIFIED.
