NTSB narrative
WHILE AWAITING TAKEOFF CLEARANCE, THE CAPT STATED THAT HE OBSERVED A FLASH OF LIGHT & SMELLED SMOKE. HE INITIATED THE PAX EVACUATION CHECKLIST & ALL PAX EVACUATED THE ACFT. EXAM OF THE ACFT BY COMPANY MAINT PERSONNEL REVEALED THAT THE NO. 1 GENERATOR CONTROL UNIT (GCU) LOCATED BEHIND THE FIRST OFFICER'S SEAT EXPERIENCED INTERNAL FAILURE. THE GCU WAS REMOVED FOR FURTHER EXAMINATION. EXAM OF THE UNIT REVEALED THAT A DIODE LOCATED INSIDE A TRANSFORMER WAS SHORTED, WHICH OVERHEATED THE TRANSFORMER & PRODUCED THE SMOKE. ACCORDING TO BOEING, THERE HAVE BEEN 12 SIMILAR OCCURRENCES.
Probable cause
FAILURE (SHORT) OF A DIODE LOCATED INSIDE A TRANSFORMER WHICH IS LOCATED IN THE NO. 1 GENERATOR CONTROL UNIT.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status, damage. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 1992-08-27.
