Just wanted to post a quick note. Going through my 1st annual on 58D and am on day 2 and so far nothing major
. Just some minor repairs and squawks getting done. Did find a couple of bad/cracked plugs and lead almost of the magneto - don't know how I did not notice this during runups or flying
Also tail wheel where it attaches to leaf spring was very loose like it was ready to fall of so this got repaired as well. We are just putting things together and getting the brackets and hardware bolted to the fuselage as well as the axles replaced and putting the skis on. I just hope the lakes freeze over soon and we get some snow!
I may post a more detailed description after all is said and done as well as some pictures.
Fly safe!

One of the reasons I bought the C-170 was it is the type of airplane that with some elbow grease you can save alot of money on. I do owner assisted annuals. My last annual I was able to complet for under $600 and was able to do a complete and through inspection fo teh airplane. I learn more about the 170 every annual.

Time for a quick update and experiment with pictures. I hope it comes out ok.
Items found:
No paper work on AD for mags so we took them apart and found them in compliance - just no paperwork logged
(but we did find a bad cap)
Elevator cables too tight (adjusted)
rear tailwheel bearings bad
Tailwheel bolt to spring had wrong nut on and was almost off
3 bad plugs
Broken Pilot seat frame (welded) - I guess it's time for that diet
Replaced VSI - was not working
Repaired CHT gauge (broken wire)
All in all it was a fun experience as well as educational. Being an Auto Mechanic for close to 30 years helped but I learned fixing a car and working on a plane are 2 different things. I am glad I found someone that I trust and respect to help me on future annuals and projects as time goes on. And I FINALLY get to fly on skis this weekend!!! YAHOO!
Weighing the plane
Skis finally on!

So how much did your plane weigh?

I don't have the numbers here - 1st time we weighed it with skis we came up with something like 1680 empty - I knew that was not correct. He re-weighed it this week and came up with a lower weight and is 100% confident in his numbers. I had to work this week so I was not there and he has the paperwork with the plane. When I get these, I will post them.

I recently replaed the main tail wheel spring and found the nut attaching the wheel to the leaf spring is not cottered, but rather a self locking type nut. Must the nut be cottered?

The one that was on was a self locking nut that was working it's way off. I was told that it was suppose to be a castellated nut with a cotter pin. That is what we replaced it with so hopefully it will not loosen up - shouldn't anyways!

The parts book will tell you which is the proper nut to be used on the tail wheel attach bolt.

Paul,
Have you got enough snow in Rhinelander for ski flying? How about ice on the lakes? My Cub is ready on its skis, but I'm sitting here in Minneapolis, freezing my butt and looking at brown earth everywhere. Jeez Louise!

Hi John;
Lakes are frozen over - rumored at 6" ice. We also have about 3" on the ground. I am picking up 58D either Sat or Sunday and hitting some snow covered grass strips. I will wait till I see some cars on the lakes before attempting to land. I really don't want to make the front page of the paper
. Maybe over the winter I will meet you at some of the Ski Plane fly-ins as I really want to put some hours on this winter.

Paul according to the parts manual the nut that does on the bolt that holds the tail wheel assembly to the spring is an AN365-720 which is a nylon self locking nut.
Your plane is illegal with that AN7-20 and AN310 nut combination.
BTW My AN635 nut comes loose overtime and is one of my preflight checks. I seem to remember others mentioning finding this nut loose as well.
I think it happens because there can be play between the wheel assembly casting, the spacer and the spring. Turning the plane puts side load and a rocking motion on the assembly which no matter how tight you get the nut the rocking will ratchet the nut off the bolt.
