The CAA accident report was published yesterday and an anon posted a link in the general research bread yesterday.
The report was the biggest load of bullshit with many inconsistencies and contradictions.
The Cessna was supposed to e in a steady glide but had airspeed fluctuating between 60 & 100kts.
At point of collision the Cessna had a bank angle of 110 degrees relative to the chopper.
To me it looks like the Cessna was jockeying for position prior to impact and tried to run his wingtip into the arc of the rotor blades.
