Narrative:
While taxiing on turf encountered a non visible sink hole. Right gear leg sank approximately 18-24 inches, resulting in propeller strike, broken wheel pant and bent propeller. On investigation a broken pipe in drain field had allowed a subsurface cavity to occur. When the aircraft gear ran over it, the gear broke the surface and descended into the cavity.
