Narrative:
On a passenger part 135 trip during departure climb phase of flight; I (the PF) and trip assigned PIC was looking at our destination non-controled airport data/information. While at FL310(?) we were given an 'expect' to climb clearance to FL340. The PNF answered FL340. I heard the sic say FL340 and set number in the altitude alerter and commenced a climb to FL340. I believe I heard the controller say expect; but when I saw the PNF set the altitude; I confirmed FL340 with him and he acknowledged. ATC asked if we were climbing and the sic replied yes we cleared to FL340. ATC said it was an expected altitude; and continue at a good rate. Upon reaching the altitude; we were given a frequency change and I told the sic/PNF to ask if there was a problem -- no; but it was close. I feel that it is the inability of the sic to hear radio calls. The last time we flew the exact situation happened. We were given an expect altitude; but the sic set the altitude in the alerter. We are both PIC's in the aircraft. From now on I am going to verify the altitude with him before he sets it in the alerter. He is in his late 50's and had been a construction worker prior to his flying career; which I think has led to his inability to hear.
