Simultaneous double jet engine failure resulting from different and unrelated faults is statistically extremely remote and is generally ruled out as a non-player.
Double engine failure mostly results from a common fault:
1. Fuel supply to the engines.
2. Fuel quality.
3. Environmental conditions affecting fuel supply to the engines.
4. Maintenance or systemic error related to such critical tasks such as engine lubrication or inspection ports not secure...
5. External environmental conditions such as extreme weather events...torrential rain and hail or multiple bird strikes.
Take your pick...
