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) After aircraft departed Portland Oregon (pdx) approx. 30 minutes into the flight smoke started filling the cabin. The pilot secured electrical systems and asked controllers to return to pdx. The controllers gave N1942G priority handling and the aircraft landed without further incident. Maintenance inspectors revealed that the air conditioning circulation motor had over heated and caused smoke to be injected into the cabin. A replacement motor is being pursued and a recommendation for an m&d has been suggested. Motor p/n HE81293-3.
