Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The flight crew was unable to lower the nose wheel landing gear through either the normal or backup systems. The airplane subsquently made a nose gear up landing resulting in minor damage to the airplane. An examination of the nose gear drag brace assembly revealed a broken drag brace pawl block link which left the nose gear in an up and locked position and precluded it from being lowered in flight.
