Narrative:
I am a first officer for air carrier flying the canadair regional jet (carj). On dec/mon/99, I was conducting the preflight inspection (as per my operations manual and flight standards manual) on carj xyz (manufacturer's production line number), when I noticed what appeared to be small chips in the teflon tape covering the cambered top portion of an outboard flap. Metal was visible through the chips. Following prescribed procedures for reporting mechanical discrepancies, the captain entered my discovery in the aircraft's maintenance logbook. Air carrier maintenance control dispatched a mechanic to our gate, and after he inspected the affected area he removed the aircraft from service. It seems that the flap system in the carj is susceptible to serious wear conditions, which render the airplane unairworthy even though they appear to only be minor cosmetic damage.

Title: A CL65 ON PREFLT CHK WAS FOUND TO HAVE WEAR AND GOUGING TO THE UPPER SURFACE OF THE R OUTBOARD FLAP.
Narrative: I AM A FO FOR ACR FLYING THE CANADAIR REGIONAL JET (CARJ). ON DEC/MON/99, I WAS CONDUCTING THE PREFLT INSPECTION (AS PER MY OPS MANUAL AND FLT STANDARDS MANUAL) ON CARJ XYZ (MANUFACTURER'S PRODUCTION LINE NUMBER), WHEN I NOTICED WHAT APPEARED TO BE SMALL CHIPS IN THE TEFLON TAPE COVERING THE CAMBERED TOP PORTION OF AN OUTBOARD FLAP. METAL WAS VISIBLE THROUGH THE CHIPS. FOLLOWING PRESCRIBED PROCS FOR RPTING MECHANICAL DISCREPANCIES, THE CAPT ENTERED MY DISCOVERY IN THE ACFT'S MAINT LOGBOOK. ACR MAINT CTL DISPATCHED A MECH TO OUR GATE, AND AFTER HE INSPECTED THE AFFECTED AREA HE REMOVED THE ACFT FROM SVC. IT SEEMS THAT THE FLAP SYS IN THE CARJ IS SUSCEPTIBLE TO SERIOUS WEAR CONDITIONS, WHICH RENDER THE AIRPLANE UNAIRWORTHY EVEN THOUGH THEY APPEAR TO ONLY BE MINOR COSMETIC DAMAGE.
