Aircraft involved
Factual narrative
THE ACFT HAD A MAIN GEAR ONLY LANDING AFTER THE NOSE GEAR FAILED TO LOCK DOWN. THIS WAS THE FIRST FLIGHT SINCE A NEWLY OVERHAULED NOSE GEAR WAS INSTALLED. IT WAS DETERMINED THAT WHEN THE NOSE GEAR WAS INSTALLED AND BEFORE IT WAS CORRECTED, A WRONG WASHER WAS USED WITH A BOLT TO INSTALL PART OF THE DOWNLOCK MECHANISM. THIS RESULTED IN AN UNDETECTED PERMANENT REDUCTION, BELOW THE DESIGN CLEARANCE BETWEEN THE DOWNLOCK PLUNGER AND ITS INTERNAL-BEARING. EXAMINATION OF THE DOWNLOCK AFTER THE LANDING INCIDENT DISCLOSED THAT THERE WAS SCORING OF THE PLUNGER AND ITS BEARING.
