Hi tatelyle,
And this was not an electrical fire. The reason for this fire and others like it in the region is likely to be linked to the way crews operate. But I cannot tell you the reason why this happens, because nobody will talk about it. Not even the NTSB or AAIB.
Er.... The accident report is available from the Egyptian CAA website (but very slow to download). Another copy here
B777_SU-GBP.pdf
See page 35.
The cause was attributed to missing electrical wire clamps and sleeving which allowed the PVC covered Stainless Steel wire around the FO's O2 hose to rub, cause an electrical short circuit and start a fire which was then fed by the crew's O2.
In what way is that linked to the way the crews operate?
