DCA airlaw is very similar to ours, there is the 500ft law.
Contrary to our media suggesting that a talented young man was killed due to flying in JB on old planes or bad instructing, it is probably due to his own actions.
I believe no instructors will ever teach those stunts he did on his first few area solo. Throughout 8 years of flying I nv bank my wings past 60AOB, not even once.
Reason for what he did was that he was bored and wanted to seek excitement as well as to try to spot the potian wanton mee stall. On his blog he mentioned that the stall warning on 9M-EYM was fault. It may have played a part in the crash of the aircraft.
It may be possible that while banking the aircraft steeply, the AT4 loses airspeed rapidly and he didn't notice due to inop stall warning. The aircraft when into a stall and a spin immd due to wing down. This may match what the eye witness description of the aircraft circling as it goes down.
