Air Canada Emergency Landing at SFO

Looks like Air Canada had more fun at SFO today...albeit not as serious as the last incident.

Air Canada flight to YVR evacuated in San Francisco after smoke alarm goes offAN FRANCISCO (NEWS 1130) — An Air Canada flight was evacuated in San Francisco Sunday morning after the smoke alarm went off.

It turns out, there wasn’t a fire.

A witness, Skip, works at San Francisco International Airport and says he saw passengers clearing out of the plane and saw the plane make an emergency landing.

“And all of a sudden people started pouring out of the wings in the front, but no flames or nothing. It had to make an emergency landing and interrupted a bit of runway service here at SFO.”

Skip adds he also saw one passenger jumping off the plane after it landed. “It’s like an eight-foot drop,” he says.

Air Canada says smoke was detected in one of the plane’s bathrooms, but the source is of it is still under investigation. Investigators with the US Federal Aviation Administration and maintenance crews are trying to figure out what happened and inspecting the plane to make sure it doesn’t happen again.

Presumably, not in that order. ;)

Do news media simply not hire editors any more?

To achieve an eight foot drop on the CRJ takes some doing. It's actually about 5 foot to the bottom of the main pax door. (6 feet is the critical height where slides etc start to be needed, per 25.810) And if the main door is open, there are stairs. The wing is more like 3-4 foot to the ground - which agreed isn't a small drop, but it's not 8 feet. I guess if they had climbed on the nacelle first they might have managed to make it 8 feet.

How much change in rear door height when the nose wheel is missing?

The rear door on the CRJ9 is an option. AFAIK, the Jazz aircraft don't have it.

Some crucial lessons learned on how to handle a possible inflight lav fire in the decades since 1983. And the lav smoke detectors were an NTSB recommendation from their analysis of the Air Canada 797 tragedy.

No !
They don’t employ reporters either, just cut and paste from facepage, tweeter etc etc

The Jazz crew gave the tower the fuel in pounds. Would that be the normal indication on a Canadian CRJ? I realize that there is some Air Canada history on that issue from when they got those new-fangled 767's a while back.

And yes, I've flown planes with fuel in pounds and kilos. And, a long time ago in gallons (but not imperial gallons).

[Loose rivets]

My fuel was once metered in cubic metres at Brussels, the aircraft used Imperial gallons but the load sheet needed pounds. All done on a Boots slide rule costing 10/6. ( a lost cursor replacement cost me a shilling.)

This was a 900 series, very different from the 200 specs you quoted. Top of the wing would be about 8’ .

Looks like Skip took some video as well

Bombardier quote the CRJ9 wingtip height (depending on loading, obviously) as 76 inches.

Allowing for the thicker wing at the root, minus a bit for dihedral, you're about 6½ ft / 2 m off the ground when you're standing on the wing outside the E/Es.

I was operating an aircraft many years ago, where we uplifted in litres, did the loadsheet and flight plan in kilos, had the inboard tanks indicating Imp gallons, and the outboard tanks indicating US gallons. Kept the brain active.
