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.

At 08:20 am the pilot departed bow enroute to jzi. Aav approach notified the pilot to recycle the transponder and he was handed off to beaufort approach who notified him that his transponder was not working. The pilot scanned the instrument panel and noticed that the alternator inop light was illuminated. The pilot followed procedures to reset the alternator without success. The pilot cancelled his flight plan and elected to land at Charleston Executive Airport (jzi). The pilot used the emergency gear extension to lower the landing gear, with the help of the sole passenger. At 10:25 am upon landing the pilot and passenger stated that they felt the main gear touch the runway and that the nose of the aircraft just kept going lower until "all three gear collapsed". The propeller blades were to aft in a tight curl. The outside of the nose gear doors and the inboard main gear doors had a little paint scuffed off of them and the skin was also slightly ground. The bottom of the step was ground flat and the step tube was cracked more than 180 degrees around and bent up, close to its attachment point to the airframe. The belly skin was heavily damaged with the flanges of the fuselage formers, bulkheads, stringers, and the main keels ground away. A determination of what caused the alternator problem could not be determined.
