The aircraft was not fitted with an AI or DI.
It did have a venturi powered T&B.
Forecast was a 70% chance icing at 2000' amsl.
Terrain along the track was around 2000' amsl.
He was unfamiliar with the aircraft having just purchased it that morning (and which for what it is worth had done 2.6 hours since last annual and that had expired ).
He had received 3 weather briefings that morning, all indicating IFR conditions along his route. He departed anyway in an aircraft he had just purchased, that had barely flown in 12 months, that had no AI or DI, had a venturi powered T&B, in forecast icing conditions with vis below VMC in mist and rain, a cloud base forecast to be 600' AGL, for a long, multistage cross country flight to make a family get together later that day.
He ended up in cloud and soon after impacted the ground.
Poor bastard but I don't care how many hours he had - that to me is really bad judgement and was an accident all set up to happen.
Do you really believe the most likely cause of that accident is unexpected turbulence from a wind farm? Sorry smells like a textbook loss of control in IMC accident to me.
