Narrative:
I am training a 4000 hour ATP to perform as a captain for the part 135 cargo company I work for. We had IFR conditions and were practicing multiple approachs on an IFR flight plan. I had failed the captain's attitude indicator and directional gyro -- the first officer's instruments were fully operational. We had completed a VOR approach into ontario and were being radar vectored for an ILS approach into ontario. My student reached for his vent (I believe) and began rapidly losing altitude. Since he did not notice the altitude loss, I began telling him to watch his altitude. By this time he was able to react, we had lost 500 ft from our assigned altitude. He was able to rapidly regain the altitude without further incident.

I HAD FAILED THE CAPT'S ATTITUDE INDICATOR AND DIRECTIONAL GYRO -- THE FO'S INSTS WERE FULLY OPERATIONAL. WE HAD COMPLETED A VOR APCH INTO ONTARIO AND WERE BEING RADAR VECTORED FOR AN ILS APCH INTO ONTARIO. MY STUDENT REACHED FOR HIS VENT (I BELIEVE) AND BEGAN RAPIDLY LOSING ALT. SINCE HE DID NOT NOTICE THE ALT LOSS, I BEGAN TELLING HIM TO WATCH HIS ALT. BY THIS TIME HE WAS ABLE TO REACT, WE HAD LOST 500 FT FROM OUR ASSIGNED ALT. HE WAS ABLE TO RAPIDLY REGAIN THE ALT WITHOUT FURTHER INCIDENT.
