After reading the preliminary report on the ERAU Arrow wing separating, it got me wondering what the Mooney spar and wing look like. I'm not worried about my wing falling off, just curious. Does anyone have any pictures of a wing without skins, or a drawing?   https://app.ntsb.gov/pdfgenerator/ReportGeneratorFile.ashx?EventID=20180404X13226&AKey=1&RType=HTML&IType=FA
