Hi guys. I've been wanting to upgrade the PA-12 gear. But curious as to the big reasons for doing so. Also how much work is it? And should I go to the 3" extended if I do?
My 12 had check cables that ran up to the top of the bungee truss. When I had the stock 12 gear, I had a failure of the cross tube at the bottom of the bungee truss, it was a fatigue failure that let go with a hard landing. I now have 18 gear with the bungee truss removed and the seat modified to accommodate that (Ron Sullivan STC).With cub gear you can run check cables, I may be wrong but 12 gear doesnt have the option, at least I have never seen or heard of it
there is nothing wrong with the 12(reinforced) gear....
Hey geezer I got the check today. Thank you very much. You should be getting gear anytime.
I am not certain that gear strap tube addition/modification is an AD or just covered by a Piper service letter as a recommendation. http://www.univair.com/piper-pa-12-and-pa-14-index/
Do not miss the one on cracked aileron bell crank ears, leaving that little washer out is expensive. Jim
To pick up on a old thread. Is it worth putting a stock pa-18 gear on a pa-12? Cost for used pa-18 gear around $300 (+ STC) , or new pa-18 gear setup $2000 +? Since I'm restoring the pa-12 just wondering and wanting to upgrade the gear, Just wondering if I should shell out the extra money now.
I might have missed this in the thread, but reinforced may also refer to an extra bit of tubing welded between the bungee strut and the main gear tube.Helps keep it from collapsing under side compression loads. probably not approved, but you'll see plenty of them. The original flat strap had little strength under compression loads, and the streamlined tube is pretty important even in normal ops- especially in crosswinds.
I seem to recall some sort of a bulletin for installing a streamline tube on that flat strap from my early years (1962) of being an A&P.I might have missed this in the thread, but reinforced may also refer to an extra bit of tubing welded between the bungee strut and the main gear tube.Helps keep it from collapsing under side compression loads. probably not approved, but you'll see plenty of them.
