Narrative:
While descending through FL340 for FL180, I, the PF, disconnected the autoplt due to rapidly increasing airspeed towards vmo. While gradually applying aft stick force, a loud jolt-severe buffet and rapid increase in pitch altitude was observed along with a spoiler fault ECAM. After regaining control of the aircraft and completing the ECAM, I was advised of 2 flight attendant injuries in the aft cabin. The remainder of the flight was uneventful. Supplemental information from acn 569081: while descending from FL370 to FL180, I was the PNF. Aircraft oscillated: increase in airspeed, pitch up, and then a push over to nearly level flight. ECAM: flight control speed break fault. Notified of flight attendant's injuries. Coordinated with dispatch, ATC, and maintenance controller. Uneventful approach and landing at ewr.

Title: A320 CREW HAD FLT ATTENDANT INJURIES AFTER ENCOUNTERING SEVERE TURB AND AN UNCOMMANDED SPD BRAKE DEPLOYMENT.
Narrative: WHILE DSNDING THROUGH FL340 FOR FL180, I, THE PF, DISCONNECTED THE AUTOPLT DUE TO RAPIDLY INCREASING AIRSPD TOWARDS VMO. WHILE GRADUALLY APPLYING AFT STICK FORCE, A LOUD JOLT-SEVERE BUFFET AND RAPID INCREASE IN PITCH ALT WAS OBSERVED ALONG WITH A SPOILER FAULT ECAM. AFTER REGAINING CTL OF THE ACFT AND COMPLETING THE ECAM, I WAS ADVISED OF 2 FLT ATTENDANT INJURIES IN THE AFT CABIN. THE REMAINDER OF THE FLT WAS UNEVENTFUL. SUPPLEMENTAL INFO FROM ACN 569081: WHILE DSNDING FROM FL370 TO FL180, I WAS THE PNF. ACFT OSCILLATED: INCREASE IN AIRSPD, PITCH UP, AND THEN A PUSH OVER TO NEARLY LEVEL FLT. ECAM: FLT CTL SPD BREAK FAULT. NOTIFIED OF FLT ATTENDANT'S INJURIES. COORDINATED WITH DISPATCH, ATC, AND MAINT CTLR. UNEVENTFUL APCH AND LNDG AT EWR.
