The METAR showed a light south-easterly surface wind, so that wouldn't have been a factor. But there is a discernable slope (downwards west to east) in the terrain between the Bristow apron on the western edge of the airport and the passenger terminal, so good old gravity may have played a part. |

Looks to me they were possibly manoeuvring the aircraft a little bit by hand rather than using a tug? Hence the lack of chocks, 6+ people surrounding the aircraft etc.

I guess I didn't know my speakers were off, because on re-viewing it actually does..:O |

AAIB field investigation conducted by correspondence?

Looking at the guys trying to stop it (?), there could have been a very nasty outcome.
|
Loads of us that are furloughed will have to get back in the zone that was very likely with those that were in the video. Currency for a lot of us that are professional fight crew, CC , Engineers and others has been serverly degraded in the last few months. Going back to work needs us to think and remind ourselves that we are not current.

Thread drift... when I worked for deHavilland in the early '80's, Dash 8 number one, C-GDNK (named for DH Director Donald Kendal) was painted for its roll out. As with airplane things, there was a bit of a rush at the last minute, so we were there Sunday evening just after the final coat of paint went on. I was just hanging around, I had no actual role in preparing the plane for display. It was determined that the tug which had pulled the plane into the paint shop, could not easily be positioned back to push it out. So six of us, and one elderly painter carrying a set of chocks, pushed it out. Four of us each took a main wheel, and two more pushed on the main gear legs, as there was no other place to push on - new, and not cured paint. We couldn't quite get it over the hump of the hangar door tracks, but by then, the tug could be positioned to finish the job.
But yes, rolling any plane by hand, with no plan to stop it is a bad idea. And placing the chock under a wheel in motion is certainly hazardous! |
My question is why the individual who was on the aircraft didn't jump into a seat and apply the brakes?

It looks like the Dash 8 was on 31 and the Embraer on 11, so the DHC rolled in a roughly eastward direction:
I also checked across pad 31 and the slope is about the same all the way across but by then I had done the screenshot. https://cimg4.ibsrv.net/gimg/pprune....9fdd05702f.jpg |
My question is why the individual who was on the aircraft didn't jump into a seat and apply the brakes? if the accumulator was depressurised, the brakes would not operate until the engines were turning, or the accumulator was recharged with a ground hydraulic rig. |
Great to have some serious intelligent conversations on the mishap instead of the usual aircraft crash vultures!
|
Would be interesting to know when the chocks were removed and by who, or was it parked up without them and these guys set things in motion..The video will hopefully have the evidence for that.
|
The airport authority have everything they need to investigate. I am not rated on the Q400 and while I know the likes of a Jetstream 41 has no standby electro pump, am surprised the Q400 has not. Then again my other ratings are regionals where standby hydraulic power is highly desirable or essential.

Given that both the rudder and steering, (along with the brakes) require hydraulic pressure to operate it wouldn't have made any difference.
Might as well be a spectator outside as be one inside. |
The Q400 has a hand pump in the right landing gear bay to pump up the brake accumulator. Nothing could be done in the cockpit once the aircraft started to move.
