Is there a problem with the gear geometry?
I'm told that the MD-11 is affectionately known as the 'Turtle' at some operators because it rolls on its back and heads for the water in a mishap. It has been speculated that the wing comes off before the gear shears in many cases, perhaps the CL-600 series is similar.
