## Discrepancy

IN DESCENT THROUGH APPROX 16,000 FEET AND AROUND 300 KTS, THERE WAS A NOTICABLE AIRFRAME VIBRATION THAT LASTED UNTIL WE SLOWED THROUGH ABOUT 270 KTS.  ENGINE/POWER CHANGES HAD NOT NOTICABLE EFFECT ON THE VIBRATION.  NO INDICATION OF ANY ENGINES PROBLEMS WERE NOTED.  SEE LINE MAINTENANCE WORK ORDER NR 600213176 AND NR 2004971 FOR WORK ACCOMPLISHED.  A FUNCTIONALY CHECK FLIGHT WAS PERFORMED WITH NO VIBRATION NOTED.
