It begins.....wings off

Postby Poncho73 » Tue Nov 21, 2017 2:44 am

Well last week I started de-fueling, flap, aileron removal. Then cables and electrics on Saturday, finally today in -2c temperatures....in sunny Canada, we popped the wings off. Over the winter, new skins, fuel ines, PPonk and a ton more.....nothing money can't fix. :D. I will upload a picture once I minimize the size

Ahh, the excitement of opening a fresh can of worms. :wink:
I'm entering the second year of my one year project and I still think I'm a year away from finishing it.
Are you just re-skinning the tops?

Bought my plane from Brampton, did my first take- off in a 170 when I left with it. Have a few co-workers there as well whom are retired now, so I know there's lots of talent in the area. Care to share tHe project/plan? I think David nailed it,

Hopefully this uploads...I hope it is not a two year project but I'm OK if it is I have other airplanes I can use in the meantime, just none as fun as the 170.

It will be new Ceconite skins and repaint. While the wings are off, realizing next year will be the birds 70th birthday, I think it is time to do some major inspecting including some AN hardware replacement.

Basic Plan...to be amended daily.... :D : new wing skins, all wing wiring to be replace, and landing light motor overhaul
tailplane removal and inspection, including attachment bolt replacement.
landing gear removal and box inspection, P Ponk mod to be installed after gear leg cleaning and repaint.
Control Yoke remove and inspection and repaint.
Icom- IC-A220 to be installed

Going forward the list will grow I'm sure.

Not a bad time to have a good look at the control cables and pulleys.
My 170 only has 1400 hours TT but both rudder cables had lots of broken wires at the rear fairlead. The only way to really check them is to get them out of the fairlead and give them a bend. Had a few seized pulleys too.

What year was that you bought the 170 from Brampton? And registration....

C-FIHK; bought it from Earl Smith in 95. It was painted beige, with brown and orange accents, had been kept outside on the grass and was in poor shape to say the least.
We returned CFIHK to Brampton after the convention in 2014, parked a couple of nights by the flying club before flying back to the West coast.
Hope you have a great heater for that hangar so you can keep to your production schedule :D

OK, Earl is still around and as a matter of fact I had lunch with him a couple of weeks ago. I will let him know IHK is going strong....small world.....I thought the reg was familiar.

I have no heater or door on my hangar :( ......however, I have a friend with a heated hangar and I will likely move the airplane to his hangar next month.

Poncho.... This would make an EXTREMELY interesting and VALUABLE article for the 170 NEWS... PLEASE take more pictures than you think necessary and any notes on how your discovered/solved any problems encountered. YOU are a PIONEER and we need to document this. :P

Fuel lines are now in, very big job. Plenty of metal work as well, including trial installation piping.....pressure/leak check to follow, including debris check. I will need to resize the pictures to post

Also I removed the main gear brake line holder rivets today. This is in order to remove the gear legs for inspection and paint. Really I believe this should have been accomplished years ago, I don’t think they have been off ever. Corrosion is evident once the rivet is removed. Word to all, drill the rivet head with a 1/8 drill only enough to chisel off the rivet head than use a small punch to remove the remaining rivet. This is to ensure you do not damage the gear leg. The rivets were removed cleanly and easily using my method.

The right side fuel line from the selector to mid floor, aft of front seat, was the most challenging. Needed to cut three holes. One large access hole beside the gear leg inspection panel and two in the gear box forward and aft bulkhead. I will utilize machine screws for the gear box panels upon reinstall. Hopefully the pics will help explain things.

Some gear leg clip pictures. I really think this should have been removed years ago. Again you can see I gingerly removed the rivet head in order to preserve the leg from drill damage.
