A Scoot Airbus A320-200N, registration 9V-TNF performing flight TR-478 from Singapore (Singapore) to Langkawi (Malaysia), was enroute at FL340 near Penang (Malaysia) when the crew declared Mayday reporting smoke in the avionics bay. The crew decided to divert to Penang for a safe landing on runway 04 about 20 minutes later.

The aircraft remained on the ground in Penang for about 31 hours, then positioned back to Singapore but has not yet returned to service about 63 hours after landing in Penang.

A listener on frequency reported the aircraft was in contact with Penang ATC when the crew declared Mayday due to avionics smoke and diverted to Penang.
