Flydubai B738 near Kiev on Apr 19th 2014, IFE could not resist smoking
Last Update: December 2, 2014 / 17:16:49 GMT/Zulu time
The United Arab Emirates GCAA released their final report concluding the probable causes of the incident were:
The Air Accident Investigation Sector (AAIS) determines that the causes of the smoke that emitted from the visual display unit VDU of seat 9A were:
- Gasses emitted from the PCB of the VDU backlight inverter board.
- Heat caused by increased current demand after the break in the secondary coil of the transformer followed by the failure of the primary side transistor components.
- The failure of the fuse to open quickly and isolate the circuit due to its inappropriate rating related to the VDU application and possibly other reasons not determined by the Investigation.
Contributing Factors to the Incident
Contributing factor to the Incident was that the material of the fuse might have helped in transferring heat by 'conduction' between the fuse and the PCB of the backlight inverter board.
The GCAA reported that cabin crew already identified the smoke was originating from the visual display unit of the inflight entertainment system for seat 9A. The system was removed after the flight and heat damage was found inside consistent with the inverter printed circuit board (PCB) being heated by heat transfer from the fuse and emitting smoke as result. The current demand had increased due to a failure of the secondary winding of the transformer of the VDU's power supply, the fuse however did not trip because its current rating was substantially higher than needed for VDU operation.
The GCAA analysed that the responses by cabin crew, flight crew as well as the aerodrome had been in line with the required procedures.
