B767 HAS AN ALLEGED ENG SPOOL DOWN ON VERY SHORT FINAL FOLLOWED BY A NORMAL LNDG.

Narrative

I FLEW A VISUAL APCH CONNECTED TO THE AUTOPLT AND ILS TO RWY 25R AT LAX. I CLICKED OFF THE AUTOPLT AT 1200 FT MSL AND LEFT THE AUTOTHROTTLES CONNECTED. THE APCH WAS VERY STABLE. AT APPROX 250 FT MSL; THE AIRPLANE SUDDENLY YAWED TO THE L. CAPT IMMEDIATELY STATED 'ENG ROLLBACK.' I IMMEDIATELY PUT IN CORRECTIVE RUDDER AND PERFORMED A NORMAL AND SMOOTH LNDG. MY HANDS HAD BEEN ON THE THROTTLES THE ENTIRE TIME AND ONLY SLIGHT MOVEMENT OF THE THROTTLES HAD OCCURRED. THEY BOTH WERE KEPT ALIGNED. I DISCOVERED AFTER LNDG THAT UPON FAILURE OF THE ENG; CAPT HAD IMMEDIATELY CYCLED THE FUEL CTL LEVER WHICH APPARENTLY RESTORED THE L ENG. IT OPERATED NORMALLY ON THE GND. SUPPLEMENTAL INFO FROM ACN 647507: CAPT SAYS L ENG SPOOLING DOWN; THEN PUTS L FUEL CTL SELECTOR TO CUTOFF AND RUN. THE ENG THEN SPOOLS UP; LNDG NORMAL. CALLBACK CONVERSATION WITH RPTR ACN 648100 REVEALED THE FOLLOWING INFO: MAINT FOUND FROM THE DATA RECORDER THAT THE ENG DID NOT LOSE RPM UNTIL THE FUEL LEVER WAS MOVED TO CUTOFF. OTHER FINDINGS INDICATED THAT THE LEVER DETENT WAS WORN.
