Narrative:
Upon arrival at the aircraft, the inbound captain was talking with the mechanic about a flag on the #1 needle of the radio direction distance magnetic indicator. They couldn't get it to work after trying many different VOR frequencys. A radio mechanic was called in who couldn't get it to work either. It was determined that it could be deferred, and it was as the #1 radio direction distance magnetic indicator pointer inoperative. The placard was complied with (place a sticker next to radio direction distance magnetic indicator). Unfortunately, it was later discovered (by a mechanic in ZZZ the next morning) that the entire VOR was inoperative, and none of the needles for the #1 VOR worked. That item is not deferrable, and we had flown an illegal aircraft with the wrong item deferred. Nothing adverse happened during the course of the flight due to this missed item.
Original NASA ASRS Text
Title: AN AIRBUS 320 WAS DISPATCHED IN NON COMPLIANCE WITH THE L AND R #1 VOR POINTERS INOP ON RADIO DIRECTION DISTANCE MAGNETIC INDICATORS. DEFERRED IN CONFLICT WITH THE MEL.
Narrative: UPON ARR AT THE ACFT, THE INBOUND CAPT WAS TALKING WITH THE MECH ABOUT A FLAG ON THE #1 NEEDLE OF THE RADIO DIRECTION DISTANCE MAGNETIC INDICATOR. THEY COULDN'T GET IT TO WORK AFTER TRYING MANY DIFFERENT VOR FREQS. A RADIO MECH WAS CALLED IN WHO COULDN'T GET IT TO WORK EITHER. IT WAS DETERMINED THAT IT COULD BE DEFERRED, AND IT WAS AS THE #1 RADIO DIRECTION DISTANCE MAGNETIC INDICATOR POINTER INOP. THE PLACARD WAS COMPLIED WITH (PLACE A STICKER NEXT TO RADIO DIRECTION DISTANCE MAGNETIC INDICATOR). UNFORTUNATELY, IT WAS LATER DISCOVERED (BY A MECH IN ZZZ THE NEXT MORNING) THAT THE ENTIRE VOR WAS INOP, AND NONE OF THE NEEDLES FOR THE #1 VOR WORKED. THAT ITEM IS NOT DEFERRABLE, AND WE HAD FLOWN AN ILLEGAL ACFT WITH THE WRONG ITEM DEFERRED. NOTHING ADVERSE HAPPENED DURING THE COURSE OF THE FLT DUE TO THIS MISSED ITEM.
