There were three SAS Q400 incidents that led to them grounding the aircraft for a time. There have also been many more undercarriage incidents which are described in this article.

The landing filmed by the pax looked very standard ... I've put things down harder than that without breaking anything.

Well done to the Cabin Crew. I've flown with Flybe on many occasions and have always found them to be extremely professional, courteous and approachable.

Porrohman,
There were indeed 3, but I was referring to the 2 that were the same cause. The 3rd was some months later and down to a different mechanical reason.
There have been numerous gear issues on the Dash q400 some of which have not even found their way into wiki.
Drawing parallels betwean this incident and previous ones is a fairly useless exercise as, if the cause is indeed mechanical I suspect it will be yet another new issue and it will be some time before the investigation reveals their findings.

I've no doubt that's largely true Dave, but the Q400 has previous form in this regard:

Propeller crashes through aircraft fuselage hitting passenger in the head - Independent.ie

As well as the famous (amongst dash drivers anyway...) SAS Q400 gear failure video that you mention, where the propellers shoot off. I'm glad to see it doesn't appear to have happened in this case!

I should also add, hats off to the crew for keeping the machine fairly straight and on the runway!

Monday 20th

Flew into Southampton from Manchester as a passenger on that very aircraft last Monday evening (20th Feb). It was a crosswind landing and we landed very hard on that right hand gear.

From the video, it looks like the wind was quite strong from the right weathercocking the nose of a/c into the wind; Also the flare was very shallow and the touchdown was borne by the left leg, difficult to judge rate of descent and if there was any drift at contact resulting in added torsion.

Not an easy situation, definitely a hard landing but the landing gear should be strong enough to handle that..

Left? right?

Al Dente... Firm but not hard. Thurleigh's story sounds feasible...

When BBC News showed footage of the incident yesterday evening, they dubbed the Mayday call onto the video. But the soundtrack began when the aircraft was on short finals, giving the impression that the Mayday call was made while the aircraft was still in the air!

From the 'front' video it does seem that that ROD did not reduce into a flare. However, I seem to remember a u-tube video of 'scary landings' where there was a FlyBe on RW33 at BHX in what looked like worse conditions. The gear survived that one. Indeed the x-wind was so strong that day they could have landed on a very short-wide runway.

Is this a/c not designed for rough short field ops? That would factor in some extra strength into the u/c components. The engineering inspection will be interesting. Also, I wonder at the elevator input. There was no bounce. The gear seemed to just fold under on impact; i.e. there was no last second attempt at any flare with up elevator. More info from those experienced on type.

Impressive...

It took only a few hours to get:
- A rear view landing video from outside.
- A passenger sitting landing video.
- The landing radio calls.
- Another video of the landing from outside. But front view this time.
- I am not even mentionning all the online flight tracking things.

That should put any company crisis management team on their toes!




Or everybody this day and there were expecting something bad to happen

The gear appears to have collapsed without any significant provocation.
In view of the weather I suspect that it may have been weakened by a heavy arrival earlier in the day.

Indeed. Looking at the video again and again I cannot say other than: good job guys.

Well, less so than DHC's "bush planes" up through the Dash-6/7. An intentional decision, after weak sales of the Dash-7, to emphasize operational cost and cruise performance over short/rough ops.

Not by a large margin, and I expect the original DHC8-100 was still overengineered. But one wonders how much leeway was lost in Bombardier's doubling of the landing weight in the -400s, especially if maintenance was less than perfect.

Full marks to the crew for holding the wing during the one-wheel roll, and to cabin crew and pax for their swift and orderly evacuation. Incidents such as this make me realise just how much air travel is taken for granted even in these very difficult wx conditions.
