Anyone ever sheared the travel stop bolt in a J3 Cub Bungee Strut?

I did, one is sheared, the other side is bent. Guess they should've been changed earlier. Sure makes the girl sit a little crooked until its fixed!

That's what annual inspections are for: to catch stuff wearing out before it breaks altogether. I have often found badly worn hardware in some critical places. A common place is in the Cessna seats; the AD against those seats demands that they ciome out and get the seat locking stuff checked; it's an easy matter to check the rest of the seat and find the cracking seat bottom frame brackets and the worn clevis bolts in the seat back pivot and seat back angle cam assembly. I have found those bolts worn three-quarters of the way through, and if they broke the seat back would lay down, possibly during takeoff acceleration, with a result similar to a seat rail lock failure: the pilot will pull back on the controls to pull himself forward, and the airplane will stall and crash.
