## Analysis

PRIOR TO LANDING THE PLT OBSERVED THAT THE GEAR DOWN LIGHT FOR THE RIGHT GEAR DID NOT ILLUMINATE. HE RECYCLED THE GEAR 2 OR 3 TIMES, BUT THE GREEN GEAR DOWN LIGHT WOULD NOT ILLUMINATE. GROUND PERSONNEL REPORTED TO THE PLT THAT THE GEAR APPEARED TO BE DOWN. DURING THE LANDING ROLL THE RIGHT GEAR RETRACTED & THE ACFT WENT OFF THE RIGHT SIDE OF THE RWY. INVESTIGATION REVEALED THAT THE LANDING GEAR WAS IMPROPERLY RIGGED.
