Toronto place crash 2

[LittleInch]

A Delta plane appears to have touched a wing tip during landing, ripped the wing off then promptly flipped over onto its back.

As they were on the airfield and this time didn't run into anything or catch fire, everyone is alive, though not surprisingly some injuries.

All passengers survive crash landing as plane flips at Toronto airport

Eighteen of the 80 people on board were injured after the Delta plane overturned on landing.

This video https://www.dailymail.co.uk/news/article-14407855/delta-plane-crash-toronto-fireball-footage.html makes it look like a very hard landing - no visible flare

I want to have a look at the top arm pivot point and yoke on the main gear.

Will see if I can find one on the apron tomorrow and get sone pictures.

Don't know anyone that fly's one.

I haven't seen that one. That videos shows the severity of the impact much better. I think this video helps rule out wind gusts as a factor. Nothing changes about the airplane's flight path. It doesn't bank, it doesn't yaw, it doesn't sink, it doesn't flare, it just flies straight into the ground.

I used to worry about safety going to and from flyin camps.
Fly in, work for 14 days, fly out, 7 days off and fly in.
And of course ther were overlaps.
The plane that I flew in on would take a full load of workers back out.
There were a lot of flights. (Several thousand men in camp. One project had a 7500 man camp and a short distance away, a 5000 man camp.)
I have seen as many as three 737s on the apron at once on flyin day.
This was (IATA: HZP, ICAO: CYNR)
This was a privately owned airstrip adjacent to the camps, for the use of the Oil Company.
I imagine that there was a lot of pressure on the charter operators to be on time.

One flight was a little late.
The pilot opted to land with the wind rather than take the time to go downwind and come back.
There must have been a wind gust.
The plane dropped suddenly onto the runway.
A couple of overhead compartments flew open and quite a few oxygen masks deployed.
There were a couple of sore backs.

I had to suspect that some aircraft defects may have gone unreported until the contracted flights were done for the day.


But Big Oil was paying the bills, and in Alberta Big Oil rules.
Fly on time, regardless or we get someone else.

Pivot point and how landing gear mounts to wing spar? I am thinking it is just as likely than wing mounting point for landing gear pivot point could have failed.

The other thing is the diagonal arm that locks landing gear in down position and the mounting point to gear and structure. In my viewing of the poor resolution videos, I can't tell whether wheel goes straight up or swings up, or some of both as it vanishes.

It may have swung up

Can you please offer your interpretation of this picture? I see some white stuff and some less white stuff.

It may have swung up

Looks the the Vanishing Landing Gear and Wing have reappeared. Great photo find. Looks like it swung up to me, and outer tire suffered rapid deflation.

 

[Alistair_Heaton]

This is what I have managed to find.




Wouldn't suprise me if the c-series is very similar.which is going to be my first port of call when I go to work today.

That's a picture of the right wing which detached. It's interesting in that the main gear is still attached to the wing, but has folded back up into it's retracted position showing a possible failure of the locking mechanism which made the gear essentially fold back up under the plane. As can be seen from the front view, if you lose a landing gear the wing will impact the ground as there is no engine to slide down the tarmac.

 

[Alistair_Heaton]

If the gear is still attached to the main spar then the spar box has failed or the spar to box connection.

That's not unheard of, corrosion and maintenance events can be a factor.

 

[LittleInch]

Interesting video here.

That locking strut doesn't look like it goes much beyond 180 degrees.

Suspect they will be looking very hard to find that piece.

Here's another image of the detached wing and gear showing the gear most likely is in the retracted position. At first I thought it punched straight on up like other failures have but seems not.
