## Discrepancy

DURING FLT, VIBRATION FELT IN CONTROL COLUMN.  HIGH FREQUENCY VIBRATION STILL FELT AT 250 KTS-270 KTS.  VIBRATION MOST PRONOUNCED WHEN BANKING LEFT; ESPECIALLY WHEN RIGHT BANK ESTABLISHED, THEN LEFT CONTROL (ROLL) INPUT ENTERED.  AIR RETURN TO MEM.  WHILE REDUCED HIGH FREQUENCY VIBRATION STILL FELT AT 250 KTS-270 KTS.  VIBRATION MOST PRONOUNCED WHEN BANKING LEFT; ESPECIALLY WHEN RIGHT BANK ESTABLISHED, THEN LEFT CONTROL (ROLL) INPUT ENTERED.  MAINTENANCE INSPECTED LT TRAILING EDGE SEAL, FOUND IT NEEDED SOME ADJUSTMENTS TO 3 OF 5 SECTIONS.  INSPECTED ROLL SPOILER ACTUATORS & ROD ENDS ALONG WITH CABLES TO BOTH LT & RT SIDES, ALL CHECKS GOOD.  A/C NEEDS TEST FLIGHT FOR SLIGHT VIBRATION CHECK.
