What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) On the fifth landing of the night, normal touchdown with 3 green (down & locked) landing gear. On roll out the PIC noticed the nose kept going on down to the ground. The nose gear had collapsed. After getting the aircraft back to the hanger it was found that the rivits that connect the nose gear landing actuator to the bulkhead had sheared inside the cabin. This allowed the thin bulkhead to flex FAR enough forward to unlock the overcentering arm. This allowed the nose gear to collapse and the aircraft to sink to the runway. Records check showed no maintenance had been performed since last annual in feb. 2002 at which time the nose gear actuator had been resealed.
