Piper Cub Struts
Anybody out there know why rag and tube Pipers need to have the struts x-rayed and Aeroncas, Cessnas etc. don't? Does this make the Aeroncas etc. potentially unsafe? They corrode just as well as the Piper struts being made of the same material. I wouldn't want to take any chances in this area as having wings clap hands over my head would DEFINITELY spoil my day but I would like to know just how bad corrosion has to be before the unthinkable happens.
Playing devil's advocate, is this a repetition of the crankshaft corrosion fiasco that grounded so many planes a few years ago? Remember that? It was when they found NEW,off the shelf, Continental cranks with machining marks which exceeded the corrosion pitting allowance and were thus scrap in the CAA's eyes. Nobody ever proved that corrosion caused a crankshaft to shed a prop yet thousands of pounds were spent inspecting and/or repairing perfectly serviceable aircraft.
