Maybe we can get past the 'reporting' and discuss the pertinent.
Should there be mandatory retraining and testing after an accident? While I'd like to respect every one's freedom of choice all choices in society have both restrictions and repercussions.
Recently an ultralight had to be helicoptered off one of our local glaciers after serious damage and injury to the pilot. I was talking to local people at the airport and learned that the pilot had already had three accidents serious enough to damage the aircraft in the last three or four years.
A chap flying the same kind of experimental amphibian I have was killed recently when turning final for a landing when his float touched the ground and the plane cartwheeled in. According to first reports he had made a low pass and was coming round to land- or not. He was not wearing a belt. He had already had several accidents of various seriousness and was known to be cavalier about risk.
These accidents will inevitably bring more restriction as well as giving our hobby a bad reputation, at least mandatory re-training might save a few from themselves.
