The type of helicopter in this crash has been grounded by the operator after a fault warning...

It seems that some of the helicopters had fuel level sensors giving incorrect readings.
If the Glasgow one had a gauge showing fuel when it was actually empty that would account for immediate loss of power on both engines and no fuel explosion on impact. Just a theory, but very possible.

"Once the helicopter had been removed from the building, the AAIB said that "approximately 95 litres of fuel were drained from the fuel tank system"."

It would not change anything the forces involved would destroy the human body.

What we have not been told is if it was the backup fuel tank that was drained from the aircaft and if the fuel gauge was faulty the pilot may of not had time to switch it and the elictronic system may not have warned him due to the fault and yes that would account for the lack of fire.

also would explain the engine missfireing noise that witnesses said they heard before it dropped.

I guess we will just have to wait until the investigators know the cause.
Although there is no black box, there are many computerised systems on board that store info (just like your computer does) if these parts have survived then they can get a jigsaw of information that when put together just might give a result.

I have just done a bit of Googling and found this PDF, look at section 2.5. Fuel capacity.
If Supply tank = reserve, then the fuel amount just about tallies with the amount found in the helicopter.

That's very Interesting about the supply tank, Good find, so if the supply tank is the name for the reserve and taking into account evaporation during drainage, tolerance, fuel density etc that looks like a very close match to me.

The helicopter suffered a double engine failure caused by a fuel supply failure
