Police helicopter crashes onto Glasgow pub

[NR DROOP]

Helimed 5 might

Thanks airpolice, just thinking that a base call might be the practise once Glasgow has been informed of an rtb, in order to inform the air ambo or any other ac at the base location of incoming traffic. Likewise a lifting/departure call.

Helimed 5 might

Probably not a night though, unless the Scottish Helimed work nights.

[NR DROOP]

Trust me they do.

[jayteeto]

Dave, they do inter hospital transfers. Not charity funded, they do an excellent job saving hours and hours of paramedic transit time

[SilsoeSid]

How about,

Call to Glasgow rtb
Change frequency
TRGB CHIP

... Some of you will know where I'm going with this one.

[Thomas coupling]

C'mon then Silsoe, I'll bite - why a TRGB chip and how does this conclude with no engines/no transmissions and no Nr?? Oh - and a vertical indentation mark in the roof with no fwd trajectory?

[SilsoeSid]

TC,
70 kts might ring some bells.

[DOUBLE BOGEY]

Silsoesid. If you know something, spit the f***er out and stop beating about the bush

[SilsoeSid]

I don't know anything, just putting another possible sequence of events on here.

[mickjoebill]

Supply tanks are different capacities, meaning #2 would flame out 90 to 180 seconds before #1.

Thinking through this unlikely scenario..
If one engine flamed out due to starvation, without warning, I presume it could stay airborn on a single engine?
If crew did not realise that the cause of the loss of power was a fuel indication issue (that would effect both engines) would they have tried to returned to base on the good engine?

Fuel exhaustion to one side, is there any common point where failure would stop fuel delivery in both engines, not necessarily simultaneously? I guess mechanically the systems are self contained for each engine, but can a Fadec fault or RF interference shut down both engines?
Rumours of Fadec failure occurring at Greek Olympics as a helicopter lifted from a very RF hostile area.

If the reported sortie times are correct and assuming it was tasked at if around 20:20? Then by 22:30 they would still have a margin over IFR reserve. If fuel had been an issue then surely they would have stopped at EGPH before routing via south of Glasgow and back to base.

[SilsoeSid]

Happy with that thanks W06, I was thinking more of the pilot's radio calls.

[SASless]

The Maryland State Police had a similar incident with a Bell 206 which crashed shortly after Take Off and wasn't missed for quite some time.

Is there any doubt there were numerous contacts between the Aircraft and the Police Command Post during this flight? The Command Post has a lot of information that would be of interest to the investigators.

Judging from the general direction the machine came to rest, there is a good possibilty the pilot was heading for a landing on the street. Perhaps at the last few seconds he noticed people standing there and had no choice but to change direction/speed and pull the remaining inertia out of the main rotors taking a self sacrificing chance in the heat of the moment to save those standing in his preferred landing spot.

[Adroight]

Of course. Obvious.

[Munnyspinner]

If TRGB chip, could this also suggest a more catastrophic failure on route to land as soon as practical? I have never understood why the emergency procedure isn't to proceed with immediate landing? However, this is consistent with reduced airspeed shallow initial descent then a sudden and uncontrollable descent if the TRGB did go.

If you know of a different situation other than a tail rotor problem where you close down both engines in flight, I'd like to know! I'm not of the opinion that they had no fuel left or that it was contaminated, they are just so highly improbable to me, as is both engines failing at the same time for some engine malfunction. Even a double FADEC failure wouldn't necessarily cause things to happen as they did.

I'm just thinking of what might have happened for it to have ended up as it did, considering the ac was (or should have been) in forward flight when the first thing in the sequence of events occurred.

[Winch-control]

To me it is clear, there are but 2 choices.

Number 1. There was a failing on the part of the pilot.
Number 2. There was a failing with the a/c.

Given the failings of the AAIB, it will be a long time before Number 2. is proven.
