Actually we really don't need to think about any reasons for the accident at this point. Anything we might say is just speculation. |

Yes, that's right. The most difficult part is that initial transition and MR speed control. Practice is required, and the only place you can do that is the simulator. Attempting to simulate it in flight doesn't come remotely close to what the real malfunction would look like. |

Can you please expand on that? Is it not a good idea to have a set of hands on the throttles for that maneuver? Was a pax in the other front seat or was a helicopter rated pilot in the other front seat? I can't see why a complex twin like that would not have 2 highly trained pilots flying, especially in and out of a highly visible confined area, at night with VIP's.
In this instance, my guess, having a 2nd pilot onboard would have had little bearing on the outcome. |
The crew of the 139 that lost the TRGB on/just after rotation in Hong Kong managed to recognise the problem, get the engines off and successfully ditch. Not impossible for a well trained and coordinated crew, but fortune favoured them with a clear if somewhat wet area to touch down . Here’s hoping to never finding out how well I’d do. |
I know that I should not bother, but people have lost their lives in this accident and still there are idiots that write crap like the following:

The AW169 has no throttles. It has dual channel FADEC control per engine and no manual reversion switches on the collective. |
Sorry to digress a little in this thread.
Reminds me of an accident in 2005 which can been seen on Youtube - search under "Helicopter Crash at Stadium a Bell 206 Twin Ranger Chopper Crashes in Bullfighting Ring Madrid Spain". |
I may have missed it in earlier posts - but have there been any comments as to what the wind was like around the stadium at the time?

Experienced pilot experienced with the mission, modern helicopter with all the latest technology. Occam's Razor (that good monk from Surrey) would suggest nothing mechanical "failed". The backup profile is related to PC1 and only addresses an engine failure (statistically insignificant) but nevertheless an airline industry mantra for regulators to focus on. And in itself it isn't harmful if you have bags of power and unless you back into something. A statistician might argue that the extended exposure and resultant velocity in the wrong direction negates any possible benefit of maintaining a reject area in view, but the Jim Lyons of the world have already beat this one to death. Likewise a tail rotor failing in a modern aircraft is statistically not a factor. I don't know the tailwind limitations of a 169, but design criteria is usually 30 knots, and the same pilot was just in and coming back out, so no unknowns there. I've flown out of stadiums, they are large, well-lit, and with good references, my idea of low risk. The AAIB does excellent work and will methodically arrive at a cause in good time - it is unfortunate that they still get so many accidents like this to investigate.

Yep - very puzzling accident.
Clearly a highly experienced pilot apparently operating to SOPs - LTRE wouldn't seem to be a factor. An almost brand new and very sophisticated machine - that one would assume was impeccably maintained. Could there have been some sort of one off assembly or manufacturing fault that caused a catastrophic drive shaft or gearbox failure? But then you'd think there'd be multiple independent checks of components at time of assembly? Very strange... |
I don't have anything to add on this sad accident itself (I agree that it is somewhat baffling at this stage - but I'm sure this very modern aircraft was equipped with all sorts of recorders that will yield useful input to the investigation) but, not living in the UK, I muss confess that I am surprised that this sort of operation would be allowed on what seems to be regular basis.
Is it really possible to get authorisation to land your helicopter pretty much wherever you want ? I would have thought that one would need to use designated helipads ? I am not implying anything here - just curious about what the regulations are. |
North and north easterly winds here in the Midlands so lifting out with a tailwind crosswind across the top of the stadium?
And what are those metal triangle structures above the stadium, could they have struck tail rotor on one of those? The tail rotor looks relatively intact, barely spinning on ground contact, but the tips have caught something. |
We know that P1 was a FI(H) but there are questions to be asked about the role of the occupancy of the pax in the left hand seat?
(a) As all ready mentioned was she in a pilot's uniform, if so why? (b) Under public transport operations would the collective and control column not be removed from the left hand side? (c) Was this in anyway an instructional flight, to which the owner was not aware? (d) Why would this flight not be operated at all times to public transport standards and with a two man (person) crew? In respect of bigendbob, the possibility of lifting out from the stadium in still air and transitioning into a tailwind really does raise the possibility of the aircraft striking the roof structure. No doubt engineers will inspect this soon and give us a better idea of what happened. |

Can someone confirm if this was a single pilot flight or was the girlfriend a rated copilot. I would think a rated copilot would be required and have their hands on the throttles for this kind of takeoff to insure that there would be an immediate reduction of the throttles in case of a TRF.

From the bystander videos, the flood-lit compound is a walk-though on match days, linking the main car park with the staff car park. It appears that there were no cars parked there.
The portable flood light was on and remains beside the wreckage. The compound is a split level of approx 2 feet, with a low wall separating the two levels. The tail rotor with gearbox separated and is on the upper level, a few feet to the right of the tail which appears to have impacted the low wall. The video shows the two policemen did their best with a 1.5Kg extinguisher and bare hands, god bless them. The compound appears to be the clearest spot for some distance, it is surrounded by occupied car parks, a treed reserve, and industrial buildings. Mjb |
Just a quick ask for info following something a witness said. If the main rotor failed, could it stop straight away?? & would t/r put the helicopter in a spin if that was still working?? thanks. |
East Mids nearest to Leicester.

Here we go again in the press... Hero pilot steers helicopter away from crowds/city/hotel/school
"Witnesses said...." |
An Army parachutist told me they hated doing display jumps into stadiums because of wind shear.
