## Discrepancy

(CAN) DURING AN UNSCHEDULED MAINTENANCE PROCEDURE OF THE VIBRATION DAMPER ASSEMBLIES UNDER THE CABIN FLOOR, IT WAS FOUND THROUGH THE USE OF A BOROSCOPE THAT THE IB CHANNELS OF THE LATERAL SUPPORT STRUCTURE WERE CRACKED AT THE UPPER ENDS.  SUBSEQUENT INSPECTION OF ALL OUR AIRCRAFT REVEALED SIMILAR DISCREPANCIES. (TC NR 20070204001)
