## Discrepancy

DURING TAKEOFF ROLL APPROXIMATELY 50 TO 60 KNOTS, AIRCRAFT FELT LIKE IT NEEDED MORE NOSE DOWN TRIM.  A UNIT OF TRIM WAS  ADDED, AS AIRSPEED INCREASED MORE PRESSURE WAS NEEDED, MORE THAN NORMAL.  IT FELT EXTREMELY TAIL HEAVY AND TAKEOFF WAS ABORTED.  *S/D*  LOAD IN AFT CARGO COMPARTMENT WAS WITHIN LIMITS.  CHECKED ELEVATOR AND STABILIZER RIG, BOTH WITHIN LIMITS.  TEST FLIGHT WAS MADE AND OPERATION WAS NORMAL.
