The article references the pilot saying he applied full left aileron, but nothing is said about full left rudder; the unsaid implication being that full left rudder wasn't used. The article doesn't say which engine is installed in the mishap 120, but barring an aftermarket O-200, even a typical C-85, while not overpowered, takes most of the right rudder input when going around. At best, full left aileron only makes the aircraft fully cross controlled in that circumstance, without necessarily granting a lot of rolling action; appropriate would be left rudder, if unable to provide lateral control with aileron alone.
Scary, not much time to figure it out, and it can be confusing when full control input isn't helping. The pilot is fortunate to have survived, indeed.
