Human Factors
The plan was to depart on an IFR flight plan; conduct a test flight East of the airport and then return. I was the PIC and the Pilot Flying; I conducted the takeoff and test flight and then asked the copilot if he would like the landing. He said he would so we transitioned control of the aircraft to him and I took the radios. ATC vectored us back for the GPS 06 approach. After descending through the clouds (~4000 ft) and in VMC conditions; the copilot told me to tell ATC that he visually had the airport. I reported this to ATC and they cleared us for the visual approach and told us we could cancel on the ground via telephone. I asked the copilot if he would like to cancel IFR now over the radio. He did so I cancelled the IFR clearance and switched to the CTAF frequency. We proceeded visually to the 'airport' and landed however the airport that we landed at was an Air Force Base; 10 miles West of the airport we intended to land and a runway with a similar heading.I made the incorrect assumption that he saw the correct airport. This was the first time I had met or flown with this copilot; and I spent a more than normal amount of time monitoring his flying which reduced my situational awareness; I am not familiar with this area; have not flow here recently and have only flown around that area a few times in the distant past. I did not discover that we had landed at the wrong airport until sometime on the landing rollout. If I had not offered the landing to the copilot and would have maintained control of the aircraft; I believe my situational awareness would have been greater.
