That is certainly food for thought Bruce- a lot of it. I did notice the L-19 has two main spring options listed in the IPC; could that account for the difference in sizes (i.e. 0.36" vs. 0.375")? Now I am curious about the basis of approval under which Univair was able to get the 170 sprin...

Beautiful footage in the last video. I love the climb out over the bridges. Thanks for sharing all of those.

I would like to learn more about the "heavy duty" L19 leaf. I've not seen one yet. Del, in cross referencing Univair's part numbers with TM55-1510-202-35P, the 170IPC, and the emails from Univair, the so called "heavy duty" L-19 leaf set(listed as L19TWS), is simply Univair's no...

My follow-up email: Mark, Thanks again for your feedback- I have a couple of more questions for you on the subject. First, can you tell me if the U170 series main tailwheel spring dimensionally matches that of the factory model 170 springs? Secondly, can you tell me what the difference in spring ten...

Okay, Univair got back to my request for details on the springs. Here is the first email, regarding spring dimensions: Univair Customer Service <info@univair.com> To ********************* Jul 20 at 1:06 PM Dear Joshua, Thank you for your inquiries! Upon investigating the dimensions of these tailwhee...

Out of curiosity Stogie, can you explain what may have led to your uneasy feeling that prompted the check; are there any symptoms you can connect after the fact? It could save someone a forced landing in the future.

Honestly, I don't know. He said " Remind me, and I'll bring in a photo of what can happen when you put a larger spring on a L-19". This was in lieu of our conversation, in which he said that people will not only install the larger l-19 spring on a 170, but will also put a larger spring on ...

Thanks for that Bruce. In light of my own difficulties in finding a tailwheel instructor in Fairbanks lately, I would like to add the following to the list: Fairbanks: Clayton (Clay), Craynor: Owns and instructs in a PA-18 (year round) Heather Zulkanycz: Owns and instructs in a PA-22/20 (maybe year ...

Is it legitimate to post information of instructors that I know of?

On this discussion, I have asked for feedback from an instructor of mine, who is also an engineer. I won't bother to paraphrase his thoughts on the matter, but will simply say that he offered to bring me a photo of a similar example, e.g. what happens when a larger spring is installed on the L-19. A...

There was a baggage door for sale in trade-mart not long ago. . .

That looks like a typo, given the exploded parts diagram. I would say, with no further information to go on (because it's too late for me to be doing further research today), that the intended quantity is 1.

In fact I did check the STCs, ADs, 337s, and logs before flying it David. The fact that I overlooked the strut fairings simply illustrates that I am new to the 170, and is the first piece of useful information you have provided in any of your responses to my posts. So, thanks for that tidbit.

Okay, digging further, here is what I found. First, while the TCM for the L-19 does include the Scott 3200 assembly, which is also approved for the Cessna 170, this assembly does not include the leaf spring, as shown in Scott SBI-168. It shows attachment to the springs, sure, but does not include th...

Funny, after all of this discussion of major vs. minor alterations, no one has noticed this, or at least no one has mentioned it: Appendix A to Part 43—Major Alterations, Major Repairs, and Preventive Maintenance (a) Major alterations—(1) Airframe major alterations. Alterations of the following part...
