Hello, this link below gives a few more details. I just placed a section of the article for quick viewing. I like the "This is not CSI" comment

"This is not CSI," Transportation Safety Board spokesman John Cottreau told the Canadian Press. "It's not just bing, bang, boom. There's an awful lot that goes on.
"We deal in facts. We don't deal in speculation. Sure, we can hypothesize, but those need to be scientifically examined and either proven or discounted."
The board has confirmed what many passengers have already said — that Air Canada Flight 190 not only lost altitude but also pitched violently from right to left before dropping 900 feet.
"The aircraft rolled to the right to about 35 degrees of bank and rolled to the left about 50 degrees of bank and effectively the auto pilot was disconnected," said Nick Stoss of the Transportation Safety Board.
