Narrative:

The purpose of the flight was a refresher for the pilot who was scheduled to fly the following day with an operations inspector to review his examiner's designation. On the last landing, after several normal lndgs, there was a sharp noise and the nose continued to descend until it made contact with the ground. The cause of the collapse could not be immediately determined. Callback conversation with reporter revealed the following information: callback conversation with reporter did not supply additional information as the aircraft has not as yet been inspected. The reporter did note that his type aircraft has an airworthiness directive issued by australian authorities. Further, the reporter did not check the nose wheel identify mirror located on the left engine nacelle, but did state that he had three green lights. The airworthiness directive alerts pilots and operators to the possibility of an incorrectly installed bolt in the nose gear well preventing nose gear extension.

Title: NOSE GEAR COLLAPSES ON LIGHT TWIN DURING FLT TRAINING OP.

Narrative: THE PURPOSE OF THE FLT WAS A REFRESHER FOR THE PLT WHO WAS SCHEDULED TO FLY THE FOLLOWING DAY WITH AN OPS INSPECTOR TO REVIEW HIS EXAMINER'S DESIGNATION. ON THE LAST LNDG, AFTER SEVERAL NORMAL LNDGS, THERE WAS A SHARP NOISE AND THE NOSE CONTINUED TO DSND UNTIL IT MADE CONTACT WITH THE GND. THE CAUSE OF THE COLLAPSE COULD NOT BE IMMEDIATELY DETERMINED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: CALLBACK CONVERSATION WITH RPTR DID NOT SUPPLY ADDITIONAL INFORMATION AS THE ACFT HAS NOT AS YET BEEN INSPECTED. THE RPTR DID NOTE THAT HIS TYPE ACFT HAS AN AIRWORTHINESS DIRECTIVE ISSUED BY AUSTRALIAN AUTHORITIES. FURTHER, THE RPTR DID NOT CHK THE NOSE WHEEL IDENT MIRROR LOCATED ON THE LEFT ENG NACELLE, BUT DID STATE THAT HE HAD THREE GREEN LIGHTS. THE AIRWORTHINESS DIRECTIVE ALERTS PLTS AND OPERATORS TO THE POSSIBILITY OF AN INCORRECTLY INSTALLED BOLT IN THE NOSE GEAR WELL PREVENTING NOSE GEAR EXTENSION.
