## Discrepancy

PILOT REPORTED ASYMMETRICAL FLAP CONDITION ON LANDING.  FOUND RT FLAP EXTENDED APPROX 10 DEGREES, AND JACKSCREW TO FLAP ATTACH BRACKET TORN FROM FLAP.  THE TRANSMISSION AND FLAP SYSTEM WAS INSPECTED IAW AD AND FOUND TO MEET SPECS (MEASUREMENTS HAD NOT CHANGED FROM PREVIOUS INSPECTIONS).  UPON REMOVAL FROM THE AC, IT WAS DETERMINED THAT THE JACKSCREW HAD JAMMED AT THE END OF ITS TRAVEL.  I WOULD RECOMMEND AN ADDITIONAL INSPECTION OF THE JACKSCREW EACH 500 HRS BY REMOVAL FROM AC AND INSPECTING FOR WEAR AND FREEPLAY THROUGHOUT THE TRAVEL RANGE OF THE JACKSCREW AND BARREL ASSY.  OPERATOR PLANS TO LIMIT THE SERVICE LIFE OF THIS COMPONENT TO 1500 HRS REGARDLESS OF WEAR LIMITS.  (K)
