## Discrepancy

ACFT WAS ON FINAL APPROACH WHEN DURING LG EXTENSION THE SYS CB TRIPPED DURING THE FINAL PHASE OF THE EXTENSION CYCLE.  THE LG EMER HAND PUMP WAS UTILIZED TO FINISH THE GEAR EXTENSION LOCK.  THE GEAR DOWN WAS CONFIRMED BY THREE GREEN INDICATION LIGHTS.  THE ACFT LANDED WITHOUT FURTHER ISSUES.  UPON FURTHER INVESTIGATION IT WAS DETERMINED THAT A FAULTY POWER PACK WAS THE CAUSE.
