Narrative:

Flight in IFR conditions; low ceilings (500 feet) /good visibility (6+miles) underneath.received clearance for departure from approach to fly 210 climb 2;000. All instruments normal at completion of before takeoff checklist. Departed runway; instruments normal on takeoff roll. On climb out; gear retracted; vy maintained. Initiated turn from runway heading to assigned 210; in turn attitude indicator failed and 'turned upside down.' suction gauge pegged to 7/8 o'clock position with 1 red nipple showing. Exercised my PIC authority; discontinued climb and descended (was over the ocean at this point) to visual conditions and returned to land without incidence. I was not in radar contact or communication with ATC.not my area of expertise but would offer is there a maintenance check/procedure to better predict a failure occurring.
