Jet fuel isn't really very flammable.
I was under the impression that police choppers were twin engined gas turbine things. Very reliable aircraft, wonder what brought it down?
I don't know the exact specifics, but they're all Eurocopter EC135's. I think there's some variation between forces.I was under the impression that police choppers were twin engined gas turbine things. Very reliable aircraft, wonder what brought it down?

Gearbox has to be the immediate suspect. There's no way that this was a controlled landing.I was under the impression that police choppers were twin engined gas turbine things. Very reliable aircraft, wonder what brought it down?

Strange that people say the engines were spluttering before it dropped out of the sky, could it have run out of fuel??? Doesn't sound like a tail rotor gearbox failure?? Is this a twin engine chopper? Wonder if he was trying to get back to the heli pad?
It's a twin engined helicopter.Witness on the phone to BBC News said they heard what sounded like an engine repeated backfiring, and looked up to see the heli "falling like a stone" with the rotor not turning. Its possible that a single engine failure would spit out debris which engine 2 re-ingests (I have seen this happen to a Bolkow 105) stalling the compressor which causes it to go bang-bang-bang is it flames out and reignites. Not sure this would cause the gearbox to lock and stop the rotors turning.
An alternative is that it was low and the rotor hit something. Mention was made of a 10-storey building nearby, but the eye witness said the heli was above 500ft or so when they first saw it.

Was thinking of main rotor gearbox. Reports say the main rotor was not spinning.Gassing Station | News, Politics & Economics | Top of Page | What's New | My Stuff
