John Eacott;
1992 S61 vs PA28 at Oxford, 2 dead, I watched that one happen, Culdrose, In the 1990’s C182 vs Sea King, one dead 3 badly injured, one in the US, C152 vs S76, one of the 76 crew was one of my instructors at FSI, Humberside more recently PA28 vs S76.
1995 I was on approach to Aberdeen in an S61, a mate flying one of the BAF Viscounts hit our wake, he described it as being like trampled by Bigfoot. He was an ex-61 pilot and the near loss of control shook him a lot.
Helicopter wake is bad, and a lot of people don’t realise the speeds we do, joining down wind at base we’ll be slowing from 145kt in an S76, faster in some others, a PA28 might be doing 105 down wind, 65-75 on final at 11000+ lb it takes some slowing.
