The crash site on Moel Siabod of Cessna 337 G-ATNY is high in the rocks in the centre of the picture ,I got to within about 100ft of the site but the cliffs became sheer and I felt it was beyond me on my own so better part on valour and all I came down !
The Cessna was on a private flight to Ronaldsway on the Isles of Man with 5 passengers and the pilot , the plane flew off track and headed into the mountains ! the plane was flying much too low at 2.700ft and hit 30ft below the ridge with the loss of all on board .
The accident report is available here
There is a ref to wreckage in a bog by the lake at the foot of the slope but after a search of about 1 hour I could find no remains so must assume they have been removed for some reason by some person ?
