PA-11 rebuild

[YJLopes]

Does anyone know of an STC for Cleveland 6" wheels and single puck brakes?

8.00s or maybe 8.50s is probably all this bird will ever see.

 

[YJLopes]

How about weld in shoulder harness brackets for the 11? I swear I saw them somewhere in all my digging and now I can’t find them.

Depends on the part numbers of the wheels and brakes but generally, no I don't know that there's an STC for those brakes. Only STC's for 6" wheels are the Cleveland 199-71 double pucks and the Grove 6" wheel/brake kit.

Don't need an STC for those although I think Atlee has one. Wag Aero, Univair, and Atlee dodge offer shoulder harness mounts and belts.

I’ve seen those, but they’re all bolt in. I swear I’d seen some weld in brackets recently but I can’t find them.

Which begs the question: Does the FAA’s “more relaxed” view of methods to install better restraints suggest that welding tabs to fuselage tubes would be considered a “minor alteration”? They’ll now permit “non tso’d” belts, soooo?

Airframes and Atlee both sell weld in seat belt tabs if that's what you want

Here's an FAA webpage re retrofitting shoulder harnesses:

Shoulder Harness Kits (faa.gov)

The FAA policy statement on shoulder harness installations linked to on this webpage

Issuance of Policy Statement, Methods of Approval of Retrofit Shoulder Harness (faa.gov)

sez installation is a minor if "the installation requires no change of the structure (such as welding or drilling holes)".

 

[YJLopes]

1. "A retrofit shoulder harness installation may receive approval as a minor change in these small airplanes if:

•  The installation requires no change of the structure (such as welding or drilling holes)."
  
  Straight from the policy statement...I guess bolt-in it is.
  
  Still can't find an STC for single puck cleveland brake install.

Tony Clyde makes a nice set of shoulder harness brackets for the front and back.

Thanks, I remember that now.

Ordered the STC from Atlee for the PA18 trim system today.

Ordered the PA18 seat belt STC from Univair today and they said my false spars should be ready by the end of the week.

I also go the CD from the feds today. This airplane has been in Colorado for most of it's life. It flew 2200 hrs between 1948 and 1955. It flew another 800ish by 1983-85 and has been in pieces ever since. It was also based in Glenwood Springs (5916' MSL) for quite a while with the original 65hp engine. I can't imagine it set the world on fire coming out of there. Its pretty cool to think about this old bird passing through the old Stapleton Airport too.

 

[nbills77]

That’s really cool. That thing has done some great flying especially in that area for those years. Keep the posts coming with pics. Walt sent me a few when you had it in his hanger.

Id say, good for you for bringing an old machine back to flying condition!

Looks like the tail already got braces so that is handled.

 

[YJLopes]

Prepping the wings for cover all in all they are pretty healthy. Replacing the perimeter, pulled the aux tank from the RH wing, a couple ribs and braces.

The strut next to the aux tank is steel but all the others are aluminum. Anyone know anything about this? I'm thinking about replacing it with an aluminum one just for the weight savings. Ounces make pounds!

 

[Crash Jr.]

I'm not sure if it was brought up but since everything is apart it's a worthwhile mod to change the spar and top deck to a PA-18 style. It definitely is a bit of a hassle doing all the welding and getting it right but the visibility is worth it.

Good work on the rebuild so far! Keep the updates coming

From memory I recall early J3s having the folded seam steel compression struts later replaced by aluminum square tubes.

Got that field approved many years ago on a couple but doubt I could pull that off these days.

Replaced with aluminum, They guys at Univair told me something similar. Either way I just saved a bit of weight from the wing and my wallet.

LH wing is trammeled, new perimeter ready to go.

Atlee trim STC showed up in the mail so I'm studying that problem too.

 

[Ab0ngcd]

I think the 1220# is due to gear attach points to the fuselage and cover the weight of everything from the attach points up. Since the floats are attach points below, they can add the extra weight in.

 

[YJLopes]

RH wing ready to cover, LH should be ready by the end of this week. I got new ailerons from Univair and shopping for some tail feathers. I may also need some gear legs. Fuselage will get bead blasted, super cub seat belt anchors and trim system welded in as well.

Make sure any wiring is installed BEFORE the fabric goes on!

No wiring...too complicated for this bird.

 

[YJLopes]

Photo dump with some progress. Both wings are ready for cover with all new perimeter, new ailerons, and new pulleys from Dakota cub. Useless trivia...an uncovered wing/aileron assembly with no fuel tank is 62.5#. I'll try to get a number after cover and paint.

We checked them on the fuselage one more time to make sure they still fit. Everything looks good.

Polyurethane on the floor boards.

Now on to covering. Spent a bunch on covering stuff and even found some MEK in Colorado. Time to start wrapping!

I picked up some parking brake valves because I think I'd use those. Hope to get the wings wrapped up in the next month. Heading to PHx this week to pick up a stab and set of elevators. Halfway hunting for gear legs if anyone knows of a set.

Buy new gear legs, after all your work you'll sleep better

You're probably right.....I'm beginning to lean this way.

 

[supercrow]

If you decide to go with used there are several pairs here. Some with hydrasorbs and some without. PM me if you want more info.

 

[YJLopes]

I've been NORDO for a while but this is moving forward. Both wings are covered as well as the tail feathers and gear legs. I ended up getting new legs from Univair.

The fuselage has the super cub trim system installed and the super cub front seat belts, both using FA Dodge STC's. It is also primed with EP420. Covering will happen in the next week or so. Chasing down a few things I need to install before gets covered.

I also need a cabane and shock struts. Anyone have a line on those? I was thinking standard bungees. Is there any reason I want or don't want hydrasorbs?

I'll post some pics when I get a minute to dig through them.

Looks like you have been putting Walt to work

This is going to be a great flying airplane!
