THE FLIGHT CREW WAS UNABLE TO GET A DOWN AND LOCKED INDICATION OF THE NOSE GEAR AFTER SEVERAL ATTEMPTS OF BOTH NORMAL AND EMERGENCY EXTENSION.

DURING LANDING, THE NOSE GEAR COLLAPSED. POST INCIDENT INVESTIGATION DISCLOSED A BOGUS PART INSTALLED IN THE NOSE LANDING GEAR DOWN LOCK ACTUATOR WHICH JAMMED, PREVENTING FULL EXTENSION.
