UPON EXAMINATION OF ACFT, IT WAS DETERMINED THAT ONE OF THE LT MLG ACTUATOR HYD FITTINGS HAD BROKEN OFF OF THE ACTUATOR. ALLOWING THE HYD SYS TO LOOSE A SUBSTANTIAL AMOUNT OF FLUID THAT WOULD NOT RETRACT OR EXTEND THE MLG COMPLETELY. EXAMINATION OF BROKEN FITTING SHOWS THAT IT FAILED AT A POINT FLUSH WITH ACTUATOR HSG. 90 DEGREE ELBOW PORTION REMAINED ATTACHED TO FLEXIBLE HOSE ASSY.
