## Discrepancy

AT CRUISE ALTITUDE FL340, LEVEL TWO FLAP DISAG ALERT LEFT FLAPS DROOPING 1* OUTBOARD AND INITIALLY 5* INBOARD AND CONTINUED UNTIL DROOP WAS 11*.  WITH THE AUTOPILOT HOLDING THE IRCRAFT LEVEL THE CONTROL YOKE WAS DISPLACED A FEW DEGREES LEFT.  FLAP HANDLE WAS FULLY UP UNTIL CONFIGURING FOR LANDING.  ALERT CLEARED DESCENDING BELOW 18000FT.  HANDLE WAS STILL UP.  INSTALLED LH I/B FLAP TRANSMITTER BRACKET ASSY REF SMP.  RE-INSTALLED LH I/B FLAP POSITION TRANSMITTER REF AMM 27-54-04-4.  ADJUSTED LH I/B FLAP TRANSMITTER REF AMM 27-50-00-5.  IND ARE GOOD.  BOXES HAVE CLEARED.  STILL REQUIRES LLM CHECK.  PERFORMED AUTOFLIGHT/ AUTOLAND TEST ON FFC 1 AND 2 AND ALL TEST PASS REF M/M 22-00-00-5. OK FOR SERVICE.
