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) Flight 5479, on approach to st. Louis, MO (stl) from northwest Arkansas, ar (xna), the pilots noted that the nose gear indicator was red following by a red gear handle indication. Using the standby gear indicator and noting that the hydraulic pressure and quantity were normal, the pilots confirmed that the nose gear was not down and locked. The pilots then cycled the gear which resulted in the same nose gear unsafe indications. The hand pump was stuck when the pilots performed the emergency gear extension procedure. Declaring an emergency to air traffic control at stl, ground personnel at stl confirmed that the nose landing gear was only partially extended. Following the abnormal emergency procedures checklist, the pilots landed the aircraft on runway 30L at a minimum speed and the nose gear slowly collapsed around 20 knots then came to a stop. An emergency evacuation was accomplished without injuries or further incident. (Refer to attachment for information on the emergency evacuation). The nose landing gear was removed and sent to piedmont-hawthorne aviation, FAA certificated repair station #PAIR208A for further investigation. This incident privacy data omitted is considered closed. Gear extension malfunction.
