Narrative:

On a trip between toledo and grr I was asked what we wanted for a final altitude. We were at 10000 ft. I had filed for FL220 but we had been kept down for a while and due to the short distance left on our trip, I requested 16000 ft. The controller then assigned 16000 ft, but for some reason I dialed in 17000 ft in our altitude selector and climbed to 17000 ft. The other pilot was picking up the ATIS and calling our hangar on the #2 radio at the time. Once we were level at 17000 ft, the controller asked me what was our altitude and I immediately recognized my error. We had changed frequencys and I was deviating around some WX when this occurred. The controller told us it was no problem and we completed the flight without incident. The other pilot and I discussed this and agree that both crew members need to be in the loop when given new clrncs.

Title: A CPR FLC IN AN MDT INADVERTENTLY SET THE WRONG ALT IN THE ALT SELECTOR THEN CLBED 1000 FT ABOVE THEIR ASSIGNED ALT.

Narrative: ON A TRIP BTWN TOLEDO AND GRR I WAS ASKED WHAT WE WANTED FOR A FINAL ALT. WE WERE AT 10000 FT. I HAD FILED FOR FL220 BUT WE HAD BEEN KEPT DOWN FOR A WHILE AND DUE TO THE SHORT DISTANCE LEFT ON OUR TRIP, I REQUESTED 16000 FT. THE CTLR THEN ASSIGNED 16000 FT, BUT FOR SOME REASON I DIALED IN 17000 FT IN OUR ALT SELECTOR AND CLBED TO 17000 FT. THE OTHER PLT WAS PICKING UP THE ATIS AND CALLING OUR HANGAR ON THE #2 RADIO AT THE TIME. ONCE WE WERE LEVEL AT 17000 FT, THE CTLR ASKED ME WHAT WAS OUR ALT AND I IMMEDIATELY RECOGNIZED MY ERROR. WE HAD CHANGED FREQS AND I WAS DEVIATING AROUND SOME WX WHEN THIS OCCURRED. THE CTLR TOLD US IT WAS NO PROB AND WE COMPLETED THE FLT WITHOUT INCIDENT. THE OTHER PLT AND I DISCUSSED THIS AND AGREE THAT BOTH CREW MEMBERS NEED TO BE IN THE LOOP WHEN GIVEN NEW CLRNCS.
