CL60 CREW LOST STABILIZER TRIM CTL WITH THE STABILIZER TRIMMED FOR HIGH SPD FLT.

Narrative

ON THE START OF OUR TRIP; THE FO WAS GETTING THE COCKPIT SET UP AND I NOTICED THE 'V' NUMBERS ON MY PDF WERE A MAGENTA COLOR; WHICH MEANS THAT YOU HAVE INVALID DATA COMING FROM THE FMS. I SPOKE WITH MAINT CTL AND THEY THOUGHT THAT IF WE PWRED DOWN THE ACFT AND BROUGHT EVERYTHING BACK UP; IT WOULD HELP. I TRIED THAT AND THE 'V' NUMBERS CORRECTLY TURNED TO BLUE. THERE WAS HVY RAIN ALL DURING THIS PERIOD. WE DEPARTED CVG ON A REPOS LEG TO SRQ. THERE WAS RAIN/ICE ALL THE WAY UP TO FL220. WE DEPARTED SRQ WITH 2 PAX AND AFTER PASSING 5500 FT; WE LOST STABILIZER 'CHCD.' AFTER PASSING FL260 WE LOST MACH TRIM. I TRIED TO USE THE STABILIZER TRIM AND FOUND THEY WERE BOTH INOP -- EVEN THOUGH THERE WAS ONLY THE INDICATION OF STABILIZER 'CHCD' FAILURE. WE NOTIFIED ATC THAT WE NEEDED TO DIVERT INTO SAV AND SET UP THE FMS FOR RWY 9 ILS. WX WAS 7 MI AND OVCST AT 600 FT. THE TRIM SYS FAILED AT 0 DEGS FLAPS AND 320 KTS; SO WHEN WE STARTED TO SLOW DOWN; THERE WAS A LOT OF BACK PRESSURE NEEDED TO KEEP THE NOSE UP. WE PUT IN FLAPS 20 DEGS AND THEN PUT DOWN THE GEAR AND FLAPS 30 DEGS. THE BACK PRESSURE TO KEEP THE ACFT ON GS WAS TOO INTENSE EVEN FOR THE 2 OF US; SO I ELECTED TO GO BACK TO FLAPS 20 DEGS VREF +14 KTS. AS THE ACFT SLOWED ON APCH; MORE BACK PRESSURE WAS NEEDED; SO I ADDED MORE SPD TO GIVE OUR ARMS A REST. WE BROKE OUT AND SAW THE RWY AT 600 FT. WE WERE COMING IN PRETTY FAST; SO I PULLED PWR AT 100 FT. WE HAD 9300 FT X 150 FT RWY; SO SLOWING DOWN WASN'T A PROB. IN 20/20 HINDSIGHT; I SHOULD HAVE DECLARED AN EMER TO ATC. THEY KNEW I HAD A SIT AND HANDLED ME GREAT -- GIVING ME A STRAIGHT-IN TO RWY 9 ILS. I ALSO SHOULD HAVE TAKEN MORE TIME TO FIGURE OUT WHAT PROB I ACTUALLY HAD. THE EICAS SYS FAILED TO INFORM THAT 'BOTH' STABILIZER TRIM CHANNELS HAD FAILED -- NOT JUST ONE. SO WE HAD NO TRIMS; THE TRIM WAS FROZEN AT A 1.6 DEG NOSE DOWN TRIM (MAINT CONFIRMED AFTER PULLING THE COMPUTER BOX THAT BOTH CHANNELS HAD INDEED FAILED); NO MACH TRIM. NO AUTOPLT. I HAD THE CEO OF A FORTUNE 100 COMPANY IN THE CABIN ALSO. OVERALL GREAT CRM RULED THE DAY; AND WE MADE IT TO THE CHOCKS.
