Narrative:

Conducting a multi-engine check ride with instrument privileges and had requested a local IFR clearance due to having to penetrate a cloud deck. I would have to be PIC for a short time since applicant wasn't rated for instruments in a multi-engine. We were cleared to 3000 ft MSL and later both the applicant and I thought we were further cleared to 2000 ft (radios were giving the applicant a problem). At 2600 ft, approach informed us only cleared to 3000 ft and to go back to 3000 ft. We promptly complied. I don't have a solution for the altitude bust since it was read back, but controller did not acknowledge -- or we didn't hear it. But this enforces again why the FAA discourages designated pilot examiners assuming PIC.

Narrative: CONDUCTING A MULTI-ENG CHK RIDE WITH INST PRIVILEGES AND HAD REQUESTED A LCL IFR CLRNC DUE TO HAVING TO PENETRATE A CLOUD DECK. I WOULD HAVE TO BE PIC FOR A SHORT TIME SINCE APPLICANT WASN'T RATED FOR INSTS IN A MULTI-ENG. WE WERE CLRED TO 3000 FT MSL AND LATER BOTH THE APPLICANT AND I THOUGHT WE WERE FURTHER CLRED TO 2000 FT (RADIOS WERE GIVING THE APPLICANT A PROB). AT 2600 FT, APCH INFORMED US ONLY CLRED TO 3000 FT AND TO GO BACK TO 3000 FT. WE PROMPTLY COMPLIED. I DON'T HAVE A SOLUTION FOR THE ALT BUST SINCE IT WAS READ BACK, BUT CTLR DID NOT ACKNOWLEDGE -- OR WE DIDN'T HEAR IT. BUT THIS ENFORCES AGAIN WHY THE FAA DISCOURAGES DESIGNATED PLT EXAMINERS ASSUMING PIC.
