## Analysis

THE FLIGHT EXPERIENCED SEPARATION OF THE NOSE LANDING GEAR DURING THE LANDING ROLL. INVESTIGATION SHOWED THAT THE FAILURE WAS RELATED TO THE PROGRESSION OF A PREEXISTING CRACK ON THE NOSE LANDING GEAR STRUT ASSEMBLY. THE PROBELMS WITH THE NOSE LANDING GEAR WERE RECOGNIZED BY THE MANUFACTURER WHO RECOMMENDED COMPLIANCE WITH SERVICE BUTTETIN 82-448 THAT WAS ISSUED TO DETECT CRACKS SIMILAR TO THAT EXPERIENCED IN THIS INSTANCE. THE SERVICE BULLETIN, THAT WAS ISSUED IN 1979, HAD NOT BEEN ACCOMPLISHED ON THE AIRCRAFT.
