G'Day All, In the last two weeks in Australia we have had two canopies depart the aircraft in flight! Both were Grob 109a (before the "b" model). I have noticed that passengers grab for the emergency release handle when getting themselves in to the seat. I have my handle wired with multiple strands of copper wire. I will be checking more carefully for it being pulled out before every flight in future! Anyone know where we could get either canopy frames off wrecked aircraft or new ones. Who owns the Type Certificate for the 109a? Would the production (moulds)molds still exist somewhere for the canopy frame or complete aircraft? I'm thinking of making a mould/mold for this part if anyone else is interested. Ray Tolhurst Grob 109a VH-ZAK YCDN Australia
