All 3 incidents were not caused by weather at all; rather, all 3 were directly caused by pilots who lost focus and intentionally ignored things like actual weather conditions, W&B, procedures, airspeed management, and physics (you can’t fool physics -R.P. Feynman).
Pro Tip: if you have severer airframe ice on approach, you ARE committed to landing; you won’t be able to climb back through that same ice and at a high angle of attack. Get 100% focused on landing because you ain’t gonna be able to go around at that point.
