The International Cessna^® 170 Association

The bottom leaf spring on my 170A is in need of replacement. A price check for the 0542106 leaf through Cessna revealed a list price of $1,958.00!! My curiosity is piqued by Aircraft Spruce advertising what appears to be the same leaf for $66 and change. I was wondering if anyone has had experience w/ the Spruce (or otherwise non-Cessna) leafs. Thanks!

I replaced my main spring a couple years ago with non-cessna spring. I think it came from Spruce. I first order one from the L-19 people in Mississippi, but it was a little different and I sent it back. I did not replace all the leaf springs, but now looking back, I should have. I will replace all at next annual. It is cheap insurance! Seeing as how I just reskinned the low rudder skins due to a small crack running out from a rivet.
If you do it you should consider replacing all springs while your at it.

Spruce advertises the main spring or all 5 springs. The Model 170 uses 5 springs, but the A & B models only use 4 of those 5. I'm guessing the unused leaf could be removed? I was leaning towards replacing all of them, but I wonder how much of a chore it would be to remove the unused leaf.

The spring set you get from Aircraft Spruce is just 5 loose springs
taped together.

I didn't know any better, so I bought the whole set (all 5 springs).
Other folks on this list have since informed me that the B model
takes only 4 springs, but I think it's cheaper to buy the 5 spring set
and throw the short 5th one away than to buy them individually.

If you buy the leaf spring kit from Aircraft Spruce, it will still
have the Univair PMA stickers on it....

Wow! It's amazing what they'll charge for an original part. The tailspring sold by Univair and A/C Spruce (Univair part) is FAA-PMA'd and is a common replacement for the tailspring. Save yourself the $1890-odd and by the Univair part. Mine's been fine since I replaced it.

Spruce gets the springs from Univair and Univair has two different part numbers, one for the 4 leaf and one for the 5 leaf. The 4 leaf is I think $116.00. Spruce carries the 4 leaf also but does not list it in there catalog, you have to specificly ask for it by Univair P/N U170ab. They were all out when I called so I called Univair and they said I got there last one. That was about a week ago though so they may have some more in by now. Sorry guys.

Spruce has the main leaf for the 170B in stock now. I just ordered mine today for $66 if I remember correctly.

When I bought my tail wheel spring set from Univair it contained five leaves and directed discard of the smallest leaf the four leaf applications as required.
