Jazz Q400 Right main landing gear collapse YEG

[Lost in Saigon]

The photo resolution isn't quite good enough to be sure, but it looks to me like that RH nacelle and wing tip were both dragging before the aircraft left the pavement.

Yes, it does look like the gear collapsed before it left the runway.

[justwork]

All of that damage from a blown tire.... Wow.

[Gilles Hudicourt]

Are composite blades more likely to break off and go ballistic (rather then bend and stay in one piece) when they hit the pavement than metal ones ?

[Brantford Beech Boy]

Yep. They don't bend, they shatter.

apparently all but one of the injured and hospitalized pax were released home. Hopefully the poor guy seating next to that window gets well soon!

Could've been a lot worse

Story of the passenger sitting by the prop below. Apparently it just hit her in the head and knocked her glasses off, and made her dazed. In my opinion it'd be a good time for her to go get a lottery ticket.

Christina Kurylo was struck in the head by a propeller blade that knifed through the body of the Jazz Aviation plane when it was forced to land at the Edmonton International Airport Thursday night. The plane was en route from Calgary to Grande Prairie.

“All of a sudden, something came crashing through my window and I got hit in the head,” Kurylo told CTV Edmonton on Saturday.

“I didn’t even realize that it was actually the propeller right through the window where Christina was sitting,” added Kurylo’s co-worker Melissa Menard, who was also on the flight.

Kurylo says the blow from the propeller knocked her glasses off and left her dazed, bruised and covered in fibreglass. As the cabin filled with smoke, Kurylo says a stranger sitting beside her helped her get out of the plane to safety.

“He stayed with me right to the very end. He was fantastic. He really helped calm me down,” she said.
Kurylo was one of three passengers who suffered minor injuries in the ordeal.

“A couple bumps on my head,” she said. “Basically, the right side of my body is bruised and bumped.”

That propeller thing is insane...

Are there many accidents/incidents where props went through the fuselage? I can't find many recently.

I guess bombardier are not done with this story.

[Blue Yonder]

When the TSB is done (and I think they are) with the airplane, they should gift that propeller to Ms. Kurylo. I know I would want to mount that on my wall.

On July 9, 1956 a TCA Vickers Viscount CF-TGR lost all 4 blades on the # 4 engine while in a high speed descent over northern Michigan. The # 3 engine was damaged by a blade and shut down. Major cabin damage occurred in the area of the 2 most forward row of seats. 1 passenger was killed and 5 were injured. 1 flight attendant received head injuries. An emergency landing was made at Windsor Ont.

About 15 years ago, an Inter Canadian ATR-42 lost the prop and gear box in cruise. Part of a blade penetrated the cabin, at a seat that luckyly contained no passenger.

[Oxi]

Very lucky passenger! However how much can be done to prevent this with a window? For the most it went directly through the window... being the weakest spot for penetration. Solution to take out the window?

[fish4life]

A solution could be to retrofit the meat seat windows with something like a lexan material

Seems to have been an issue with the Dash 8 dating back pretty much to day one:

NorOntair was the first airline in the world to order and take delivery of Bombardier's de Havilland Canada Dash 8 Series 100,[1] on October 23, 1984, operated by Air-Dale Ltd. The first Dash 8 in commercial service anywhere in the world wore NorOntair colours and was registered C-GJCB. This aircraft was number 6 off the assembly line and remained in active service until the closure of the company flying up to 14 hours a day across Northern Ontario. A second Dash 8 joined the fleet shortly after the first and was registered C-GPYD. This second Dash 8 was seriously damaged on approach into Sault Ste Marie one day. Shortly after the company took delivery of the aircraft, it landed hard during a cockpit crew training flight. The hard landing caused the aircraft's landing gear to collapse, causing significant damage to the newly acquired plane. Of particular concern to the airline and to de Havilland Canada at the time was the fact that the crash caused one of the engine's propeller blades to violently break away from the engine housing. The blades penetrated the cabin wall of the aircraft, travelled through Row 2 of the aircraft interior and exited through the other side of the cabin sidewall on the opposite side. Given that the aircraft was on a training flight, no passengers were on board. The flight crew escaped the aircraft without injury. The aircraft was removed from service and after months of structural repairs and refurbishment, was returned to active service.

[Canoehead]

The Dash mentioned above was stalled onto the field and came to rest beside what was then RWY 11.

As a point of interest, the DoM at Air Dale engineered and manufactured a wing spar "splint" that got that particular airplane back into the air. DeHavilland apparently tried for many years after that to hire said DoM, but he politely declined.

He is currently the DoM of a rather large flying school in YAM.

Given the width of the runway I'm surprised they ended up in the mud.

What was the final word on the SAS gear collapses. Did it turn out to be the fault of the manufacturer or the airline?

The causal factor was ineffective maintenance procedures with respect to processes used to lubricate components of the MLG. Part of the problem was maintenance instructions that were, in retrospect, too ambiguous.

Yup, SAS was so unhappy with this shoddy built aircraft that, after the landing failures, they went and ordered a dozen more Qs!

However, SAS got rid of them all, eventually, and now have zero Dash 8`s of any model in their fleet. They sold the 27 older Q400´s to Philippine Airlines and Malev. The 14 or so new ones were not operated by SAS but by a subsidiary (Wideroe) instead and never flew in full SAS colours. Finally, SAS sold Wideroe to private investors last year.

In 2011, a Wasaya BE02 had a prop blade depart the hub and breach the fuselage in Kasabonnika, ON.

[CFM Symphony]

It also happened to a Brasilia in the US in 1995.

For this particular case it seems the blade entered right through the window, which is very unlucky. I wonder how the strengthening plate would have been able to withstand the impact had it hit there first.

As I have read that the nature of the tire damage was "a piece missing", is it possible that when it spun up upon touchdown, that it shook the gear leg so much that the downlock was shaken undone, and the "leg lock" arrangement unlocked to allow the collapse?

I thought the same thing when I read this news report:


http://www.theglobeandmail.com/news/nat ... e21516648/

When the right landing gear deployed, Ms. Kurylo saw that the tire was “shredded and flapping.”

Ms. Menard said the landing initially seemed normal and passengers hadn’t been told to brace into a crash position.

Then the plane suddenly started rattling as they went down the runway. The right landing gear collapsed and the plane started tilting to the right. Ms. Menard felt as if she was in a car about to roll over.

[linecrew]

After seeing what a Metro prop did to the side of the fuselage after a gear up landing in Ottawa back in the 90s I always make sure that I don't get a seat near the prop line when booking a flight on a turboprop aircraft. On a much lesser point, it's also quieter in the back of the Dash-8 anyway.
