Blown tire on take-off from YYC. Aircraft was diverted to YEG (Edmonton, AB) for Emergency landing due to strong winds @ YYC. Right hand gear collapse upon landing at YEG. Three people injured, no details on injuries.

I have to admit that I think about the gear, every time I land in a Q400 -- they land pretty hard sometimes. Recognizing of course that a proper accident investigation will take place, does this at first blush resemble the landing gear issues with the Q400 we had in Europe a few years back?

It shouldn't - there was an AD / fix for that issue which has long since been implemented.

Does this mean that they never retracted the gear?
Because if they did, and in the impossibility of safely returning to YYC , it could have made sense to continue to destination. Unless there are maintenance / weather /runaway / Emergency services issues at destination, is not like you need the MLG to fly.

More resources in YYC


How did the crew know they had a blown tire?

But they did NOT divert to YYC (that would have made sense, just after takeoff).
And of wich kind of resources are you talking about?
You have to remember that if you do not arrive to destination, you have probably to provide for the stranded passengers

The longest runway at YQU (Grande Prairie) is 6,500ft, whereas YEG has a 11,000ft runway. That is probably a big reason, plus the greater availability of emergency medical services in a city like Edmonton. Makes a lot of sense to divert there.

Probably because of the large, tire-sized chunks of rubber left behind on departure on YYC's 35L necessitating its temporary closure.

They did not return to Calgary due to high winds.

Providing for stranded passengers is immaterial in these circumstances. A replacement aircraft can easily be flown in to fly the passengers to their destination.

They attempted to return to YYC but the winds were to strong so they diverted to YEG. Its not that big of a deal when the passengers are going to YYC or YEG. Both cities have a very large AC presence so they would have been airborne fairly quickly (YYC as hub and YEG as focus city).

Thanks Captain Obvious... On the takeoff roll or rotation how would the crew have been alerted to the blow out? (ie sensor,light) I really doubt you could hear it over the engines and it was night so Im assuming ATC could not have seen it either.

They probably would have returned to YYC but the crosswind runway 11-29 was closed, I believe for maintenance or construction. A Kelowna Flightcraft DC-10-30 freighter from YHM overshot and diverted to YVR about the same time due to crosswinds in excess of their limits. It also declared minimum fuel on approach to YVR.

I find it shocking that the propeller has pierced the fuselage, luckily nobody was sitting in that seat.

I'm curious how a tire blowout would incapacitate the gear enough that it collapses upon landing. As for the prop, I guess it is unlucky, but still reasonably logical that upon gear failure the propeller could shear off and bounce into the cabin. The fact no fatalities occurred is amazing.
Quantos,

I maintain the Airbus A220 (formerly Bombardier C Series) Aircraft Status sheet: https://goo.gl/HZshto
Feel free to comment on the sheet with any improvement suggestions and data update requests! Thanks to Paolo92 for his advice!

The flight was almost full, 71 passengers per news reports, meaning only 3 empty seats.

Are the props supposed to bend in the event of an accident?

As someone who flies quite a bit with Porter, I usually try to avoid the seats right next to the propeller. Now more than ever will I avoid them.

If both tires had failed, I'm sure that the forces on the struts would easily be great enough to snap the gear.


(Surmising scenario) If the gear had held, it might have dug into the pavement, and caused the aircraft to swing violently to the right. This could have caused more serious injuries, and even more substancial damage to the aircraft.

A quote from one of the passengers:

Quote:
Kurylo was one of five Grande Prairie radio station employees on the plane. She was sitting in row seven when part of one of the plane's propellers smashed through the window, narrowly missing her face.

"All of a sudden I got hit in the head," she said. "It was pretty confusing for me. It's bits and pieces for me after that."

"The propeller, obviously that didn't hit her, but the whole inside wall of the plane blew out so she had fibreglass and everything all embedded in her skin," said her co-worker Melissa Menard who was also on the plane.

So, I posted this too in the general forum, which subsequently got deleted. Shouldn't something this significant be there for broader discussion?
