## Discrepancy

LANDING GEAR FAILED TO EXTEND WHEN SELECTED.  GEAR WAS PUMPED DOWN AND AIRCRAFT LANDED WITHOUT INCIDENT.  INVESTIGATION REVEALED THAT THE C-CLIP ON THE HYDRAULIC POWERPACK COUPLING WAS MISSING AND ALLOWED THE COUPLING TO MIGRATE ON THE SHAFT UNTIL IT NO LONGER CONNECTED THE MOTOR TO THE PUMP.
