My flying career included virtually no experience of helicopters. I have followed this thread from the beginning. I cannot remember in the various lists of possible causes any suggestion of deliberate criminal action. Presumably, while the thought may not occur to Ppruners, there is an automatic forensic angle to the AAIB investigations.

From what appears to be original cctv footage released today..
Anyway, what strikes me unusual is the puff of smoke from the engine as the rotor starts to turn....and vertical climb performance seems to deteriorate just before directional control is lost. Uncontained engine failure that severs the TR drive shaft? |

I am not convinced - given the direction of the downwash..... delamination of TR ?
Look at 1:02 |

Of course but actually you will struggle to find an example where the early rumour differs significantly in terms of the headline to the multi year final report...
Glasgow ran out of fuel...Shoreham pilot...North Sea EC225 let those down wearing big boy pants...etc |
There were remarks from a Bt Sport technician whom mentions he heard a definite ‘grinding’ noise - the sort you hear when accidentally selecting reverse...... |
I've just watched the video - it seems that something clearly wasn't right with that tail rotor.
Anyway, scary that I was dealing with Eric professionally by e-mail not too many months ago. RIP to all. :( |
Extraneous Noise?

Just had a quick scan on YouTube to find some previous AW109/AW169s departures from the stadium:
I found this one: Although we shouldn't be making comparisons based on one video (especially as optical illusions could have their part too), the accident video shows the helicopter hovering for considerabably longer than the video above and it looks higher too. Purely a very, very, very brief observation. |

(a) There is no reason to suspect that the aircraft was in anyway defective. (b) The primary causal factor is a result of the aircraft sustaining damage during flight as a result with contact with a structure or other object. (c) If not (b) then due to the handling of the aircraft by the pilot in command, pax or both, either in error or intentionally. We for sure do not know a, but one can guess at anything. For b, primary causal factor is TBD. C. Maybe, and maybe not, but Where Are You Getting Intentionally From? That, sir (or madam) is utterly Irresponsible. Dear members of the media who may wander by here, none of that which anchor posted is supported by information, given the lack of same. Anchor: you are jumping the gun a bit there. I'd recommend dropping the short attention span act and waiting for the first (of many) reports. They'll be arriving in due course. Whether or not your guesses are close, or far, from the actuality will in time be shown.

in the interest of further safety, thats not a bad thing is it?
Regarding your idea of hitting something on the way in: what evidence are you pointing to that prompted that speculation? |

Fortunately the reports will be based on professional examination of evidence, not a need to react to poorly motivated baseless trolling.

If you're so upset about musings by others, leave the thread and don't come back. clearly you're drawn here for a reason though....is it to try and start fights? The accident investigators aren't special by any means either. they cast a wide net, rule out things as they go along in a structured way. Nothing different going on here at all except it's not so structured. They just put it onto a nice dossier in the end and publish it. |

Question from a PPL(H). Would autopilot ever be engaged on this sort of departure? At the top of the reverse climb? If there's a malfunction, does the computer compensate? How quickly can you disengage? Would it be used to allow the night blindness to settle having climbed out of a bowl lit for TV cameras into a night sky? It doesn't look sadly as there was ANY time to do anything but still interested to know the procedure for such eventualities.
As crab said, the pilot manages manually in attitude mode the Cat A take-off till the limits (height and IAS) to engage the modes are reached. Anyway if you find yourself very early in deep disorientation troubles, WLVL is an attitude function that will level your wings and bring your pitch 6 degrees up. |

What got me to respond was the insinuation of intentionality. I do not feel that such ought to be left unchallenged. That, and me being aware of who may scan this site for tidbits to throw into a news story.
Despite a couple of videos showing some aspects of the event pretty clearly, we still have people floating conjectures at odds with observable fact, such as fictitious collision with the stadium structure. If they haven't looked at the video themselves, they could at least believe those who have. |
Possible pilot disorientation (nose up, black sky), then over-pitching? |

It's worth reading the article, even if it is the Sun...
I have a sequence of photos taken by me of a recent departure of this helicopter flown by the same crew. The photos show the helicopter on the ground in the centre circle. Once the passengers have boarded the aircraft enters a low hover and turns 180 degrees, it then moves forward to the 18 yard line in a forward hover then moves backwards and upwards until it clears the stadium roof then transitions forward while climbing and off it goes. However the departure shown in the Sun video is totally different to this, it seems to climb to a much greater height way above the stadium roof before making a turn. This is purely my observation and the different departure technique may be for various operational reasons not to mention the wind direction but having seen this helicopter take off from the pitch on many occasions, I have never seen this departure technique used before from this location. |
As Malabo said this was a well flown departure all the way and one which I would expect from a professional pilot with experience. On this type of departure profile (confined area) flown from the RH seat you would yaw the a/c left to keep visual with the departure and possibly reject point in your chin bubble window. At TDP you would then yaw back to the right (30°) or so to straighten up. That's the procedure and that's what it looked like to me.
