In Australia at least, the official accident reports never blame anyone although they may imply. While US regs require a "most probable cause" to be published by the NTSB, this term is not in Australian investigations. In its place are "Significant Factors". And so you find someone kills himself in a light aircraft by hitting power lines while beating up his home and showing off.
Pilot Error? Of course it was. And obviously a fatal one at that. But this will never appear in print because it is politically incorrect nowadays to blame the pilot. The Significant Factors of this accident would be: The weather was windy...the power lines weren't there the last time he beat up his house 12 months ago. The pilot was not qualified to fly below 500 ft and so contravened the Regs. Thus it is left to the reader to form his own opinion if the pilot was foolish and paid for it with his life. But "pilot error?" Never heard of the word, mate...
