Narrative:
Climbing through FL295, we experienced a loss of the autothrottle system, the autoplt, both flight directors, the FMA, and altitude alerter. We were unable to engage either autoplt. Due to the numerous failures and lack of altitude alerter, we inadvertently climbed to FL320 with a clearance to maintain FL310. We immediately descended to our assigned altitude.

Narrative: CLBING THROUGH FL295, WE EXPERIENCED A LOSS OF THE AUTOTHROTTLE SYS, THE AUTOPLT, BOTH FLT DIRECTORS, THE FMA, AND ALT ALERTER. WE WERE UNABLE TO ENGAGE EITHER AUTOPLT. DUE TO THE NUMEROUS FAILURES AND LACK OF ALT ALERTER, WE INADVERTENTLY CLBED TO FL320 WITH A CLRNC TO MAINTAIN FL310. WE IMMEDIATELY DSNDED TO OUR ASSIGNED ALT.
