## Discrepancy

DURING FORWARD FLIGHT, CREW EXPERIENCED RAPID AND ABRUPT VERTICAL UP/DOWN SHIFT.  WINDS    WERE CALM.  PIC SLOWED AIRSPEED TO APPROXIMATELY 70-80 KNOTS AND EXPERIENCED A SECOND OCCURRENCE.  CREW DECIDED TO CONDUCT A PRECAUTIONARY LINING AT KRDU APPROXIMATELY 4 MILES TO OUR TWELVE O'CLOCK.  THE NEXT OCCURRENCE WAS EVEN MORE PRONOUNCED  AND THE PIC DECIDED TO LAND AT THE NEAREST SUITABLE LANDING AREA.
