## Discrepancy

DURING POST FLIGHT WALK AROUND, PILOT NOTICED THAT THE ROSEMONT SENSOR HAD ICE ON IT.  UPON OPERATIONAL CHECK, FOUND THAT THE SENSOR WAS NOT HEATING.  TROUBLESHOOTING THE SYSTEM, FOUND THAT THERE WAS NO POWER TO THE HEATING ELEMENT OF THE PROBE.  UPON FURTHER INVESTIGATION, FOUND THAT THE RELAY KC311 PINS- X1 AND X2 WERE PINNED IN REVERSE ORDER.  REPINNED THE RELAY AND OPS CHECKED THE SYSTEM, GOOD. (EA09200500318) (K)
