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.

Pilot switched from the main fuel tank to the aux tank for the rear engine and turned on the boost pump. No change was noted. Pilot climbed to 500 feet AGL. Front engine then also began to run rough. Pilot again attempted to clear engine by changing fuel tanks and using boost pump with no change in engine roughness.
