Narrative:
On approach, the nose gear indicated unsafe. We initiated a missed approach and were vectored clear of traffic as we performed the required abnormal checklist procedures. After the alternate gear procedure was used, as per checklist, the nose indicator light was still red -- indicating that the landing gear was not down and locked, although the indicator pin on the center console was fully extended indicating a down and locked position. Normal hydraulic pressure and quantity was observed throughout, and the alternate extinguisher handle was returned to normal as a precaution. We had the crash crew standing by. After a normal landing and rollout, and at approximately 50 KTS, the nose gear collapsed. After we came to a stop, we initiated a ground evacuate/evacuation without major injuries. Maintenance later advised us that the nose gear over-center strut had failed.
Original NASA ASRS Text
Title: MD80 NOSE GEAR COLLAPSED DURING LNDG ROLL CAUSED BY THE NOSE GEAR OVER-CTR STRUT FAILING. PAX WERE EVACED WITH NO INJURIES.
Narrative: ON APCH, THE NOSE GEAR INDICATED UNSAFE. WE INITIATED A MISSED APCH AND WERE VECTORED CLR OF TFC AS WE PERFORMED THE REQUIRED ABNORMAL CHKLIST PROCS. AFTER THE ALTERNATE GEAR PROC WAS USED, AS PER CHKLIST, THE NOSE INDICATOR LIGHT WAS STILL RED -- INDICATING THAT THE LNDG GEAR WAS NOT DOWN AND LOCKED, ALTHOUGH THE INDICATOR PIN ON THE CTR CONSOLE WAS FULLY EXTENDED INDICATING A DOWN AND LOCKED POS. NORMAL HYD PRESSURE AND QUANTITY WAS OBSERVED THROUGHOUT, AND THE ALTERNATE EXTINGUISHER HANDLE WAS RETURNED TO NORMAL AS A PRECAUTION. WE HAD THE CRASH CREW STANDING BY. AFTER A NORMAL LNDG AND ROLLOUT, AND AT APPROX 50 KTS, THE NOSE GEAR COLLAPSED. AFTER WE CAME TO A STOP, WE INITIATED A GND EVAC WITHOUT MAJOR INJURIES. MAINT LATER ADVISED US THAT THE NOSE GEAR OVER-CTR STRUT HAD FAILED.
