WHEN THE LANDING GEAR WAS EXTENDED FOR LANDING, THE RIGHT MAIN LANDING GEAR LIGHT BEGAN FLASHING AND AN UNSAFE GEAR WARNING WAS RECEIVED. SEVERAL ATTEMPTS WERE MADE TO ASSURE THE LANDING GEAR WAS EXTENDED INCLUDING REPEATED ATTEMPTS AT NORMAL AND EMERGENCY GEAR EXTENSION. UPON LANDING THE RIGHT MAIN GEAR COLLAPSED. SUBSEQUENT EXAMINATION REVEALED THAT A COTTER PIN ON THE RIGHT MAIN LANDING GEAR SCISSORS HAD BEEN OPEN AND CAUGHT A WIRING BUNDLE IN THE WHEEL WELL WHICH PREVENTED THE DOWN LOCK FROM ENGAGING.
Probable Cause: the improper maintenance installation (cotter pin) by other maintenance personnel. Factors were main landing gear scissors not safetied properly and extension of landing gear not possible by pilot-in-command (CFI).
