## Discrepancy

AIRCRAFT EXPERIENCING POPPING OF THE MAIN LANDING GEAR CB ON RETRACTION AND WAS MAKING NOISE.  AIRCRAFT WAS FLOWN, GEAR DOWN AS A PRECAUTION.  REMOVAL AND INSPECTION OF THE GEAR ACTUATOR REVEALED AN EXCESSIVELY WORN WORM GEAR IN THE JACKSCREW ASSEMBLY THAT WAS BINDING WITH THE PINION GEAR CAUSING JAMMING.
