? if '56 172 wings will work on a '51 170A

[butchpilot170]

Hi ! I'm a new member to the 170 club and am very glad to be on board with you Aviators . I'm I been a from Western Pa. (near Pittsburgh) but am residing a lot in N.J. I been a pilot for 45 years and have owned a number of aircraft . I have finally got a hold of a 170A that was crashed (nose over on landing ) and am determined to restore it to her rightful glory . If anybody has any parts or knowledge I appreciate your input . Forgot to tell you I go by the name Butch and my email is butchgoedicke@hotmail.com Verizon phone 908-489-1571 .

please be very carefull putting your personal info on the web. join the association and the information available is a hundred fold . putting 56 172 wings on can be done BUT what a job both techincally and legal wise. Also the wing struts have to be changed and all the aileron cables and flap cables have to changed and rerouted. The 170A as it is works well.

No time right now to type but in a nut shell, you will not go through with all the work required to install later 170B or 172 wings on your A.

Oh and as everyone can see, Butch is a member, he just posted prior to getting his forum privileges upgraded.

Have a little more time now. The differences between the A model and B model or 172 wing are many. A model wings do not have the same washout. They do not have the same size flaps. Yes the later wing will physically attach to the airframe.

What strut would you use? The A and B model strut are different lengths as the A model has no dihedral but the B and 172 does. The flaps are cable activated but the cable run for an A is much different than a B. In fact the flap handle itself is different. To get the flaps to work you need to change out the fuselage carry through spar to accommodate the flap pulleys.

So the bottom line is, this is not a bolt on swap.

Has it been done? Supposedly. In fact I owned an A model that had B model wings installed. In reality they where actually L-19 wings with B model flaps retro fit into them. My plan had B model struts. My plane also had B model elevators. Did you realize the A and B model do not have the same elevator? I once started counting all the parts that would have to be changed to swap from an A to B model and stopped when I went over 250. If my plane could talk we would probably learn that in fact, the plane was a B model, with an A model data tag and logs though as hard as I tried I could never prove definitively whether it started life as an A as it was licensed or a B it likely was.

For the record there are flying A models with B model elevators. B models with A model struts and no dihedral. A models with B model wings. And B models with L-19, 172 and 175 wings. I've seen them all.

Chances are you could have your A model wings repaired for what it would cost to swap B or 172 wings onto the A.

And we haven't even talked about legalities.

Sounds like another job for Del

[butchpilot170]

Wow ! Thx guys , I believe all of you on this matter . I think I'll stick to putting her back together just the way she was and do some side slipping to get in to the shorter fields if needed. I guess the big thing when going in to an airstrip is whether the o-300 can get you out . Oh, I'm the person who won the "carcass" on Ebay @ 2 weeks ago . Later, Butch !

Let's don't tie him up....We need to save Del for more serious work.

Do NOT slip your 170 with flaps! Much has been written on this subject, and I would suggest you review it before flying the plane. I didn't know about it either when I bought my plane, but fortunately the forum, along with a timely article in the 170 newsletter, set me straight. It's one of the few things you have to watch out for in a 170. Otherwise it's a pretty straightforward plane.

Actually he mentioned in his first post that he purchased a 170A. Slips with full flap are not prohibited on the A model

[Bruce Fenstermacher]

Fred is right. B model flaps and slips are a bad news. And should an A model end up with B model flaps installed, don't slip that either.

But the A model, with smaller flaps, is not restricted and it is not known to be a danger to slip with flaps deployed

Butch, I'll bet you meant "forward-slip"...intended to increase angle-of-descent, for example to clear a tree-line on a short strip...?
(as opposed to side-slip...intended to halt sideways-drift in a crosswind landing.)

Yep, the B-model flaps, if fully deployed in a forward-slip, has been found to be a dangerous maneuver with an inconsistent/unpredictable tendency to suddenly pitch the aircraft down into a spin-like loss-of-control as the downward-wash of air off those large flaps bring the horiz-stab and elevator into a stalled condition.

[butchpilot170]

I'll try and remember all the advise you people are giving on the day I can get her all put back together . Sounds like the previous owner locked on the brakes and flipped her over on landing . Having trouble getting in to the Wentworth storage locker right now and haven't even got to see how damaged it is yet . I know I need a complete 0-300 D eng. ,prop , spinner and bottom cowl . If anybody out there has these parts please contact me . later , Butch !

It's a shame we didnt meet a month ago. I sold an 800 hour C-145 for a song.
I don't have any other parts available but will keep an ear out for a motor.

Are you sure yours is shot? If it's a mid time prop strike, it might be worth tearing down for an inspection/repair vs overhaul.

[butchpilot170]

Hey thx Bagarre ! Maybe something will come along ! Someone told me that if you MOH a c-145 eng. you have to change the crankshaft = $$$$ . Could this be true ?

[FredM]

I think what they meant was if a C-145 crank requires replacement, new 8 bolt cranks are no longer available. You don't have to replace any crank if it is servicable. If you have an 8-bolt that isn't servicable it may be hard to find a servicable replacement. Installing a 6-bolt crank of course means that you have to replace the prop as well.
