Posted 30 Nov 2018 (edited) I share a hangar with someone and so I fold my wings backa after every flight. I fly at least three times per week.I am starting to wonder how much the flold backs are stressing the strut bolt at the fuselage. Has anyone with MK4s ever removed and inspected these bolts? If so what stress have you seen?John M Edited 30 Nov 2018 by skypics Share this post Link to post Share on other sites
Posted 1 Dec 2018 I looked over mine this last year and saw no significant damage or wear, after 22 years and maybe 800 hours. I think they are nicely oversized for the job. Share this post Link to post Share on other sites
Posted 1 Dec 2018 I would think the number of fold, unfolding cycles would have to be astronomical for there to be a problem. Like the elevator horn bolt on an Avid, this might be something to be inspected every so often if you fold on a regular basis. Share this post Link to post Share on other sites
