What was found
DURING PREFLIGHT, THE LT OB FLAP TRACK WAS NOTICED TO HAVE DAMAGE. AIRCRAFT WAS IMMEDIATELY GROUNDED AND THE FLAP TRACKS AND ROLLERS WERE REPLACED WITH NEW PARTS. NO FURTHER DAMAGE HAD OCCURRED TO THE FLAP ASSY. SINCE MFG DOES NOT HAVE LIMITATIONS ON THEIR FALP TRACKS, WOULD SUGGEST THAT THEY BE REMOVED AND REPLACED AT 5,000 HOUR INTERVALS. (K)
