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.
