Having known Richard for more than 30 years I am finding some of the ill informed and judgmental comments here to be both in poor taste and quite offensive.
LeadSled has explained quite succinctly that despite assumptions otherwise from those outside Australia, Richard went to great expense to have himself qualified by the manufacturer to carry out his own maintenance on his own machine, which was then ratified by CASA who issued him a Maintenance Authority to carry out such maintenance. Not only that but he spent a fortune on the tooling and parts needed to carry out such maintenance, and carried Eurocopter kits with him whilst flying into the bush to ensure that he could fix any snags whilst in designated remote areas. Snide comments by TC about the UKs accident stats with 'rich people' has no validity down under.
I suggest that discussion about this tragic loss of life come back to a reasonable discussion about known facts, and less speculative character assassination from some who have basically no idea what they are talking about.
