UK helicopter accident stats for the period 1992 to 1999 were collated by PLH Associates in 2001 from CAA maintenance returns. They showed that while the Robinson R22 now constitutes more than half the UK single-engine fleet, it accounts for far less than half of all accidents - despite the fact that it is used in the most accident-prone pursuits, like ab initio training and low-time self-fly hire. It recorded one fatal accident for every 115,000 hours. Only the single Squirrel performed better.
Despite the monotonous bell-tolling of the monomaniac Zuckerman, or the chauvinism of those too numerous to mention who have never flown Robinsons but who are only too happy to give up the benefit of their experience of the type here on pprune, the R22 remains one of the safest helicopters in the air. Don't take a lend of it and it won't let you down.
There are sound reasons why the R22 outnumbers all the others put together, and why its numbers to continue to rise in proportion to the rest.
