Narrative:

While en route; we encountered severe turbulence at FL350 at rinny intersection that resulted in an altitude loss of approximately 8000 ft. We were IMC at the start of the descent and were unable to control the descent until we broke out in the clear. We were using WX radar; however; we were not painting any WX. About 10 mins prior to this turbulence we asked ZMA for a ride report and were told that no one had complained. We were unable to contact ZMA directly during the altitude loss but we did relay our situation via an air carrier Y flight.

Title: A300 EXPERIENCES LOSS OF CTL IN TURB OVER THE BAHAMAS.

Narrative: WHILE ENRTE; WE ENCOUNTERED SEVERE TURB AT FL350 AT RINNY INTXN THAT RESULTED IN AN ALT LOSS OF APPROX 8000 FT. WE WERE IMC AT THE START OF THE DSCNT AND WERE UNABLE TO CTL THE DSCNT UNTIL WE BROKE OUT IN THE CLR. WE WERE USING WX RADAR; HOWEVER; WE WERE NOT PAINTING ANY WX. ABOUT 10 MINS PRIOR TO THIS TURB WE ASKED ZMA FOR A RIDE RPT AND WERE TOLD THAT NO ONE HAD COMPLAINED. WE WERE UNABLE TO CONTACT ZMA DIRECTLY DURING THE ALT LOSS BUT WE DID RELAY OUR SITUATION VIA AN ACR Y FLT.
