Narrative:

We were operating with a call sign of air carrier xx. Our flight plan called for 14000 ft as our final altitude. I was the PF and we were deviating to avoid build-ups, but were still encountering moderate turbulence. The captain was speaking with the flight attendant on the intercom to inform her to remain seated. Akron departure cleared us to 14000 ft and I responded to the call and set 14000 ft in the altitude pre-select. I was concentrating on avoiding the build-ups and deviating around cells when the captain checked back on with me. I told him we were climbing to xx ft. I think with the task saturation of working the radios, flying, and just dealing with turbulence, I stated a number that was incorrect (it was our call sign, not our altitude). At this moment, the captain set XX000 ft, in the altitude pre-select and we received a frequency change to ZID. The captain checked on with indy and stated 'air carrier xx, 13.5 for xx.' indy responded with a local altimeter. Passing 14.5, indy asked what our final altitude was. We responded XX000 ft. The controller said he showed 14000 ft, but cleared us to XX000 ft. It took the captain and I approximately 15 mins to think through the events that led to this deviation. Task saturation and turbulence, and a miscom between myself and the captain led to a deviation that should have been avoided.

Title: A COMMUTER FO WAS FLYING, HANDLING ATC, AND AVOIDING WX AS THE CAPT WAS OFF FREQ. WHEN THE CAPT REJOINED HIM, THE FO MISSTATED THE ALT THEY WERE CLRED TO, CAUSING CONFUSION WITH ATC.

Narrative: WE WERE OPERATING WITH A CALL SIGN OF ACR XX. OUR FLT PLAN CALLED FOR 14000 FT AS OUR FINAL ALT. I WAS THE PF AND WE WERE DEVIATING TO AVOID BUILD-UPS, BUT WERE STILL ENCOUNTERING MODERATE TURB. THE CAPT WAS SPEAKING WITH THE FLT ATTENDANT ON THE INTERCOM TO INFORM HER TO REMAIN SEATED. AKRON DEP CLRED US TO 14000 FT AND I RESPONDED TO THE CALL AND SET 14000 FT IN THE ALT PRE-SELECT. I WAS CONCENTRATING ON AVOIDING THE BUILD-UPS AND DEVIATING AROUND CELLS WHEN THE CAPT CHKED BACK ON WITH ME. I TOLD HIM WE WERE CLBING TO XX FT. I THINK WITH THE TASK SATURATION OF WORKING THE RADIOS, FLYING, AND JUST DEALING WITH TURB, I STATED A NUMBER THAT WAS INCORRECT (IT WAS OUR CALL SIGN, NOT OUR ALT). AT THIS MOMENT, THE CAPT SET XX000 FT, IN THE ALT PRE-SELECT AND WE RECEIVED A FREQ CHANGE TO ZID. THE CAPT CHKED ON WITH INDY AND STATED 'ACR XX, 13.5 FOR XX.' INDY RESPONDED WITH A LCL ALTIMETER. PASSING 14.5, INDY ASKED WHAT OUR FINAL ALT WAS. WE RESPONDED XX000 FT. THE CTLR SAID HE SHOWED 14000 FT, BUT CLRED US TO XX000 FT. IT TOOK THE CAPT AND I APPROX 15 MINS TO THINK THROUGH THE EVENTS THAT LED TO THIS DEV. TASK SATURATION AND TURB, AND A MISCOM BTWN MYSELF AND THE CAPT LED TO A DEV THAT SHOULD HAVE BEEN AVOIDED.
