Returning to Kirknewton from Cambeltown as a passenger in a DA20 there was a loud bang. I thought we had a bird strike as there was blood on the side of the canopy and I had also felt a thump. The radio stopped working also so I supposed the bird had taken the aerial off.
Then I realised the blood was mine! One of the canopy support springs had broken and taken a lump out of my elbow. I must have a slow reaction time as it took a few minutes to start to hurt The intermittant radio was just one of a catalogue of faults the aircraft had.
DO.
