## Discrepancy

DURING CLIMB HAD TO USE THE OVERRIDE GEAR RELEASE TO RAISE LANDING GEAR.  THE MAIN GEAR HYDRAULIC INTERLOCK CYLINDER CRANK WAS FOUND FROZEN WITH ICE IN THE ANTI-RETRACT POSITION.  APPLIED HEAT, CRANK OPERATED FREELY AND ANTI-RETRACT BUTTON IS NOT NEEDED TO RAISE HANDLE.  HYDRAULIC INTERLOCK CYLINDER OPS CHECKED GOOD PER MM 32-31-05.
