Unsafe Condition
Collapse of nose landing gear during ground handling, takeoff, or landing due to fatigue failure of the LH or RH nose landing gear upper drag link lower lug.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Conduct a magnetic particle or dye penetrant inspection of the LH and RH nose landing gear upper drag link assembly and measure the lower lug stiffening web for minimum thickness. If cracks are found or the web thickness is ≤0.100 inch, replace the assembly before further flight. Repeat inspections every ≤200 landings unless reworked or replaced. Replacement with specific part numbers or modification per SB 32-178 terminates AD requirements.
