## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

(-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.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft 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. For accidents, the NTSB's own investigation is the fuller record.
