This incident looks like it may be one of those cases. The pilot was on the glide slope to the airport when he runs into a microburst and decides to pull the lever before getting pushed down into the lake.
I’ve seen way too many episodes of Air Crash Investigations.
A microburst could easily take out a full-sized airline at low altitude. That’s why airports and planes have equipment to detect air shear so they don’t fly into it. Small planes are far more affected by weather and don’t typical have radar or safety systems like flight envelope protection.
