"Way-back-when" the regulators regulated, the looping and rolling of a non-aerobatic aircraft would have resulted in the immediate withdrawal of the C. of A. and the prosecution of such an un-disciplined pilot.
One can only assume that the S.A. regulatory authorities, (a) didn't see it or, (b) are unaware of the event or, (c) they feel the flight manual limitations are too restrictive.
In any case, one would not expect a professional pilot to expose the aircraft or himself to critisism by a such a blatant dis-regard of limitations
(It wouldn't have been so bad if the manouevres hadn't been so poorly executed. It looked sh$thouse. The roll looked like "Oh sh$t, what do I do now?)
(Apologies to Tony Draper for any possible mis-use of the word, "one")
