## Discrepancy

(CAN) ACFT WAS BEING BROUGHT INTO THE HANGAR FOR OVER NIGHT PARKING, PILOT NOTICED THAT WHEN HE SHUTDOWN THE ENGINE THAT THE OIL PRESSURE NEEDLE WAS STUCK IN THE MIDDLE OF THE GREEN ARC.  AME CHECKED THE GAUGE NEXT MORNING IT WAS STILL SHOWING READING IN MIDDLE OF THE GREEN ARC.  REMOVED THE GAUGE AND FOUND THAT IF YOU MOVED THE NEEDLE IT WOULD GO DOWN TO BOTTOM OF SCALE. IF MOVED BACK IT WOULD STICK WHERE YOU LEFT IT. NEW GAUGE ORDERED. OIL PRESSURE LINE CHECKED AND FOUND TO BE CLEAN. (TC 20100203012)
