Same for Aerosucre, everyone mentions overweight and start hammering the crew. .But no-one knows for sure , could also be an engine failure past V1 on a very short runway on a hot day...
It may well have been an engine failure, but surely their limited Mtow should have factored this in. If an engine stops above V1 you'd be expected to continue the takeoff
and have the required performance to get airborne before you run out of runway. They clearly didn't achieve that, so if it was just an engine failure I think you can still safely conclude they were indeed too heavy!
