## Discrepancy

(CAN) ON TAXI AFTER A ROUTINE LANDING, IT WAS NOTICED THAT THERE WAS A "BANG" NOISE COMING FROM THE FRONT OF THE ACFT.  AFTER SHUTDOWN IT WAS REVEALED THAT THE OLEO HAD COLLAPSED AND HAD LOST IT`S FLUID ON LANDING, DUE TO ICE BEING BUILT UP ON THE OLEO DURING THE APPROACH.  WHEN THE ACFT LANDED, THE ICE WAS FORCED INTO THE O-RINGS CUTTING THEM UP AND CAUSING THE OLEO TO LOSE PRESSURE AND FLUID.  THE SEALS WHERE REPLACED WITHOUT FURTHER INCIDENT.
