Holding at cacto, nwbnd, traffic called at 8 mi, northeast descending through 6000' MSL en route to phx. Flashed our landing light. Small aircraft Y called 'positive contact.' as safety pilot in right seat of small aircraft X, I also called traffic in sight (saw green navigation light). We started our turn sebnd. I continued to monitor traffic which appeared to be on collision course. Within 30 seconds traffic was running us over on his descent into phx arsa. We took evasive action. Out rear side window I saw wheels in wells, aircraft completly filled window (rear left), also heard go by. My evasive action was, I believe, necessary to avoid a midair. Cases with charts (etc) hit roof during evasive maneuver. On talking to approach after incident they said that while traffic was still northeast of us, we had 300' vertical sep (mode C on both aircraft). If indeed he was descending into phx airspace, I believe a turn would (with either aircraft) have avoided this mishap. We were in contact with phx approach for approximately 20 mins prior to incident, and vectors to small aircraft Y could have prevented this.

Title: CLOSE PROX GA SMA PRACTICING INSTRUMENT FLT AT NIGHT IN HOLDING PATTERN AND SMT ON ARR INTO PHX.
Narrative: HOLDING AT CACTO, NWBND, TFC CALLED AT 8 MI, NE DSNDING THROUGH 6000' MSL ENRTE TO PHX. FLASHED OUR LNDG LIGHT. SMA Y CALLED 'POSITIVE CONTACT.' AS SAFETY PLT IN RIGHT SEAT OF SMA X, I ALSO CALLED TFC IN SIGHT (SAW GREEN NAV LIGHT). WE STARTED OUR TURN SEBND. I CONTINUED TO MONITOR TFC WHICH APPEARED TO BE ON COLLISION COURSE. WITHIN 30 SECS TFC WAS RUNNING US OVER ON HIS DSCNT INTO PHX ARSA. WE TOOK EVASIVE ACTION. OUT REAR SIDE WINDOW I SAW WHEELS IN WELLS, ACFT COMPLETLY FILLED WINDOW (REAR LEFT), ALSO HEARD GO BY. MY EVASIVE ACTION WAS, I BELIEVE, NECESSARY TO AVOID A MIDAIR. CASES WITH CHARTS (ETC) HIT ROOF DURING EVASIVE MANEUVER. ON TALKING TO APCH AFTER INCIDENT THEY SAID THAT WHILE TFC WAS STILL NE OF US, WE HAD 300' VERT SEP (MODE C ON BOTH ACFT). IF INDEED HE WAS DSNDING INTO PHX AIRSPACE, I BELIEVE A TURN WOULD (WITH EITHER ACFT) HAVE AVOIDED THIS MISHAP. WE WERE IN CONTACT WITH PHX APCH FOR APPROX 20 MINS PRIOR TO INCIDENT, AND VECTORS TO SMA Y COULD HAVE PREVENTED THIS.
