What was found
RIGHT GEAR RETRACT ROD BENT, ON A WET WINTER DAY THE PILOT PUT THE GEAR HANDLE DOWN AND THE BREAKER POPPED. HE MANUALLY EXTENDED THE GEAR WITH THE HAND CRANK AND GOT 2 GREEN LIGHTS. 3 GEAR COULD BE SEEN FROM THE GROUND AND HE LANDED. LANDING WAS OK, BUT ON ROLL OUT THE RIGHT GEAR COLLAPSED. LIKELY CAUSE IS UPLOCK CABLE FREEZING AND PREVENTING THE SPRING FROM RELEASING THE HOOK WHICH TURNED FREELY ON INSPECTION AFTER THE FACT.
