From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(-23) Upon approach for landing and extending the landing gear the nose gear light did not illuminate with the unsafe gear unlock light showing red. Pilot requested a fly by so that the tower could identify if the gear was down. The tower reported to the pilot that the gear was down as well as the gear doors being out. This is an abnormal indication on this type aircraft. The pilot elected to perform an emergency landing gear extension per the unsafe landing condition checklist. After completion of the checklist the nose wheel light remained out with the unlock red light remaining on. Pilot declared an emergency and proceeded to land. Upon landing the pilot held the nose off the ground until approximately 50 knots. The aircraft departed the runway and taxiway onto a ramp at the end of runway 14. Maintenance was called out to the aircraft at which time the aircraft was jacked and towed to gulf coast aircraft. Upon further inspection maintenance noted that the nose gear actuator assembly s/n 384 downlock had failed. Maintenance replaced this actuator. The two nose gear doors were replaced due to minor damage.
