Narrative:
On a visual approach into roc we had a red nose unsafe light (no nose down and locked green light, both mains were normal). We ran checklist and talked to company. On landing nosewheel was down and I furnished gear pin to a mechanic to install. He said the holes would not line up and at this time the gear collapsed. The mechanic after looking in the wheel said he found a screwdriver in the downlock. Callback conversation with reporter revealed the following information: the reporter stated the gear was cycled several times and appeared down on visual check. The reporter said the landing was normal and on stopping on the runway the nose gear lock pin was given to a mechanic to lock the gear down for towing. The reporter said the mechanic advised the crew the pin could not be inserted into the lock pin hole and at this point the nose gear collapsed. The reporter stated the aircraft incurred damage to the steering links and the nose landing gear wheelwell aft bulkhead. The reporter said no passenger or crew injuries occurred but the mechanic narrowly escaped injury when attempting to pin the gear downlock. The reporter stated the direct cause of the nose gear to lock down was a small screwdriver left in the nose gear lock strut which prevented the strut from going over center. The reporter said the screwdriver did not prevent the nose landing gear from retracting and locking up but only in the extend position.

Title: A BAE3200 ON GEAR EXTENSION HAD THE RED NOSE GEAR UNSAFE LIGHT AND AFTER LNDG AND STOPPING ON THE RWY THE NOSE GEAR COLLAPSED.
Narrative: ON A VISUAL APCH INTO ROC WE HAD A RED NOSE UNSAFE LIGHT (NO NOSE DOWN AND LOCKED GREEN LIGHT, BOTH MAINS WERE NORMAL). WE RAN CHKLIST AND TALKED TO COMPANY. ON LNDG NOSEWHEEL WAS DOWN AND I FURNISHED GEAR PIN TO A MECH TO INSTALL. HE SAID THE HOLES WOULD NOT LINE UP AND AT THIS TIME THE GEAR COLLAPSED. THE MECH AFTER LOOKING IN THE WHEEL SAID HE FOUND A SCREWDRIVER IN THE DOWNLOCK. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE GEAR WAS CYCLED SEVERAL TIMES AND APPEARED DOWN ON VISUAL CHK. THE RPTR SAID THE LNDG WAS NORMAL AND ON STOPPING ON THE RWY THE NOSE GEAR LOCK PIN WAS GIVEN TO A MECH TO LOCK THE GEAR DOWN FOR TOWING. THE RPTR SAID THE MECH ADVISED THE CREW THE PIN COULD NOT BE INSERTED INTO THE LOCK PIN HOLE AND AT THIS POINT THE NOSE GEAR COLLAPSED. THE RPTR STATED THE ACFT INCURRED DAMAGE TO THE STEERING LINKS AND THE NOSE LNDG GEAR WHEELWELL AFT BULKHEAD. THE RPTR SAID NO PAX OR CREW INJURIES OCCURRED BUT THE MECH NARROWLY ESCAPED INJURY WHEN ATTEMPTING TO PIN THE GEAR DOWNLOCK. THE RPTR STATED THE DIRECT CAUSE OF THE NOSE GEAR TO LOCK DOWN WAS A SMALL SCREWDRIVER LEFT IN THE NOSE GEAR LOCK STRUT WHICH PREVENTED THE STRUT FROM GOING OVER CTR. THE RPTR SAID THE SCREWDRIVER DID NOT PREVENT THE NOSE LNDG GEAR FROM RETRACTING AND LOCKING UP BUT ONLY IN THE EXTEND POS.
