Narrative:

During descent I heard a 'soft bang' and felt a thump. Thought perhaps it had been a bird strike or landing gear door malfunction. I reduced airspeed and shortly afterwards noticed the red 'gear in transit' light was illuminated. Slowed further to well below vlo and extended the gear with the normal system. Green lights for left & right main gear; none for the nose and in transit light remained illuminated. Flew by the tower at 300 ft. AGL with their permission and they reported gear appeared normal. Departed the pattern to consult poh and completed the prescribed emergency extension procedure. Still no green light on the nose. Requested emergency personnel and equipment meet us on the runway and returned for landing. Normal touch down; landing and roll out. Stopped adjacent to the emergency equipment and shut down. Released the emergency crews and inspected the gear; no obvious anomaly and requested tow to the FBO. Subsequent investigation revealed broken bolt between nose gear actuating rod and nose gear drag brace.

Narrative: During descent I heard a 'soft bang' and felt a thump. Thought perhaps it had been a bird strike or landing gear door malfunction. I reduced airspeed and shortly afterwards noticed the red 'Gear in Transit' light was illuminated. Slowed further to well below Vlo and extended the gear with the normal system. Green lights for L & R main gear; none for the nose and in transit light remained illuminated. Flew by the Tower at 300 ft. AGL with their permission and they reported gear appeared normal. Departed the pattern to consult POH and completed the prescribed emergency extension procedure. Still no green light on the nose. Requested emergency personnel and equipment meet us on the runway and returned for landing. Normal touch down; landing and roll out. Stopped adjacent to the emergency equipment and shut down. Released the emergency crews and inspected the gear; no obvious anomaly and requested tow to the FBO.
