NTSB Narrative Summary Released at Completion of Accident

The MD-88 declared an emergency and returned to the departure airport after the crew smelled an electrical odor during the climb to cruise. After landing the crew observed small flames emanating from the Captain’s side of the glareshield. A maintenance inspection revealed that the right wing landing light switch displayed evidence of severe heat damage and no other source for the fire could be identified. No anomalies with respect to switch installation were noted by the personnel who removed the switch. The “Right Wing Landing Light” (B1-15) and “Right Wing Landing Light Control” (B1-16) circuit breakers were also found to be open following the event. A Systems Group was formed and the Group examined the switch at the Eaton facility in Milwaukee, WI. The switch was severely fire damaged with the greatest amount of thermal damage and contact degradation occurring at the B1 contact. The cause of the switch fire could not be determined.

NTSB Probable Cause Narrative

The cause of the right wing landing light switch fire is undetermined.
