## Discrepancy

DURING STRAIGHT AND LEVEL FLIGHT, PILOT NOTICED FLIGHT CONTROLS STARTING TO FEEL STIFF.  THIS WAS IMMEDIATELY FOLLOWED BY A DROP IN HYDRAULIC PRESSURE.  PILOT LANDED ACFT SAFELY IN A FIELD.  MECHANIC WAS DISPATCHED AND FOUND A HYDRAULIC LINE HAD RUPTURED DUE TO CHAFING.  IN ADDITION, HYD LINE PN 205-076-201-1 HAD A SMALL CRACK UNDER THE B-NUT AT THE COMPRESSION FITTING.  NEW LINES WERE INSTALLED, HYDRAULIC SYSTEM SERVICED, AND AIRCRAFT RETURNED TO SERVICE.
