Another Broken Tailwheel Spring

Post by rnealon1 »

After a Connecticut snowfall found the main tailwheel spring snapped in two and tail sitting on grass. No obvious existing crack. Just happy it didn't happen while landing.

Besides replacing broken main spring it makes sense to me to replace all the springs but wondering what else might be suggested while I have the Scott 3200 home in the garage.

Thanks,

Bob

That is definitely the preferred place to discover your spring is broke! :D The megaphone behind you does an excellent job of magnifying the racket of that stub dragging on the tarmac, no rudder damage and you didn’t loose your tailwheel.

It's my opinion replacing ALL the leaf springs is a waste of money but no harm otherwise. Complete disassembly/inspection/repair of the tailwheel is always a good idea from time to time.

I concur with George. I'd change out only the main spring. The design is a set up for a failure of the main spring which is why they break. That does not exist with the other springs in the pack. Unless you have reason to believe those have been fooled with ie changed out with home made stuff or you see some other defect in them, they are good.

BTW guess your as lucky as I am as I also discovered my main spring broken at the tie down.
CAUTION - My forum posts may be worth what you paid for them!

Bruce says it all in one sentence.

"Set up for failure"

Why do we as owner/operators of Scott 3200 tail wheel aircraft accept occasional failure? Why?

It's not just us. Have you ever had to rebuild/reseal a nose-wheel oleo-strut? Or main gear oleo-struts? Our configuration is a wonderful dream.

Simple tailspring solution: Change that cheap spring every 500 hrs.
