Narrative:
When 4 NM west of cim VOR, descending through FL260 for FL250, we encountered about 30 seconds of moderate and a few moments of severe turbulence. We were descending to remain clear of an area of reported turbulence as turbulence reverser engine #2 annunciated on the left MFDU and the associated checklist on the right MFDU. The checklist procedure failed to clear the fault. We did not apply the reverser unlocked procedure as it did not apply and could have worsened the problem. The aircraft was not buffeting or rolling and we were able to maintain FL250 with the #2 engine at idle. We were discussing our options including diversion when the #1 flight attendant informed us the #3 flight attendant was injured while in the aft galley during the turbulence. Her injuries were reported to be in the hip and spine. We declared an emergency and diverted to ama, reported the turbulence to ATC, and requested through ama operations and ama approach that an ambulance meet the aircraft. The approach and landing were conducted with the #2 engine at idle and included a briefing on what action we would take if the reverser did deploy uncommanded. Touchdown and rollout were smooth and the ambulance was waiting at the gate. Supplemental information from acn 355076: runway length was 13000 plus ft, belaying landing distance considerations. Approach and landing were uneventful, and both reversers deployed and stowed normally. Flight attendant was met by paramedics and transported to hospital in ama.

Title: FK100 ACFT. FLC IN DSCNT AND ATTEMPTING TO AVOID RPTED TURB. HIT MODERATE TO SEVERE TURB, RESULTING IN A #2 ENG THRUST REVERSER MFDU UNLOCKED INDICATION, AS WELL AS INJURY TO A FLT ATTENDANT. FLC DECLARED EMER AND DIVERTED TO AMA ARPT. REVERSERS OPERATED NORMALLY ON LNDG, AMBULANCE MET ACFT AND TRANSPORTED CABIN ATTENDANT TO HOSPITAL.
Narrative: WHEN 4 NM W OF CIM VOR, DSNDING THROUGH FL260 FOR FL250, WE ENCOUNTERED ABOUT 30 SECONDS OF MODERATE AND A FEW MOMENTS OF SEVERE TURB. WE WERE DSNDING TO REMAIN CLR OF AN AREA OF RPTED TURB AS TURB REVERSER ENG #2 ANNUNCIATED ON THE L MFDU AND THE ASSOCIATED CHKLIST ON THE R MFDU. THE CHKLIST PROC FAILED TO CLR THE FAULT. WE DID NOT APPLY THE REVERSER UNLOCKED PROC AS IT DID NOT APPLY AND COULD HAVE WORSENED THE PROB. THE ACFT WAS NOT BUFFETING OR ROLLING AND WE WERE ABLE TO MAINTAIN FL250 WITH THE #2 ENG AT IDLE. WE WERE DISCUSSING OUR OPTIONS INCLUDING DIVERSION WHEN THE #1 FLT ATTENDANT INFORMED US THE #3 FLT ATTENDANT WAS INJURED WHILE IN THE AFT GALLEY DURING THE TURB. HER INJURIES WERE RPTED TO BE IN THE HIP AND SPINE. WE DECLARED AN EMER AND DIVERTED TO AMA, RPTED THE TURB TO ATC, AND REQUESTED THROUGH AMA OPS AND AMA APCH THAT AN AMBULANCE MEET THE ACFT. THE APCH AND LNDG WERE CONDUCTED WITH THE #2 ENG AT IDLE AND INCLUDED A BRIEFING ON WHAT ACTION WE WOULD TAKE IF THE REVERSER DID DEPLOY UNCOMMANDED. TOUCHDOWN AND ROLLOUT WERE SMOOTH AND THE AMBULANCE WAS WAITING AT THE GATE. SUPPLEMENTAL INFO FROM ACN 355076: RWY LENGTH WAS 13000 PLUS FT, BELAYING LNDG DISTANCE CONSIDERATIONS. APCH AND LNDG WERE UNEVENTFUL, AND BOTH REVERSERS DEPLOYED AND STOWED NORMALLY. FLT ATTENDANT WAS MET BY PARAMEDICS AND TRANSPORTED TO HOSPITAL IN AMA.
