## Discrepancy

NR 2 SPOILERS APPEAR TO BE FULLY UP INTO THE AIRSTREAM CAUSING AIRFRAME VIBRATION DURING FLIGHT.  THE LT AND RT NR 2 SPOILER SERVO CONTROLS WERE PREVIOUSLY DEFERRED. DEFERRAL PROCEDURE USING A SPECIAL MAINTENANCE KEY FOR SPOILER DEACTIVATION WAS FOUND NOT CORRECTLY ACCOMPLISHED. THAT CAUSED THE SPOILER SERVO CONTROLS NOT BEING IN THE OPERATIONAL POSITION, SUBSEQUENTLY CAUSING THE SURFACES FREE-FLOATING IN FLIGHT. RE-ADJUSTING THE MAINTENANCE DEVICE ON THE CONCERNED SPOILER SERVOCONTROLS TO THE OPERATIONAL POSITION FOR CONTINUAL DEFERRAL CORRECTED THE PROBLEM.
