Have a friend with a 170B and he has a set of AWB 2500's with it. No paperwork and missing some parts from what I understand. ANyone have a copy of the paperwork I could forward to him. Thanks!

AWB retractable wheel skis are approved on the type certificate. Only thing required is a logbook entry signed by the installing mechanic, and a revised weight and balance. Reference the TC for the 170.

Here's the pertinent part of the TC:

If you need drawings for the skis, you might give Wipaire a call. They do have some of the legacy ski paperwork, but the only REQUIRED paperwork is the logbook entry and w/b.

PM me with an email address.
I have them on my 170B and have all the necessary installation paperwork.

Thanks Mike and AKclimber! I just spoke with him and I guess it is the assembly/parts info he needs. He obtained the skis and a box full of pats but has no idea how it all goes together. I believe he is/has contacted Wip to see if they have any of the old drawings and parts break down. He hasn't heard back from them yet.
Thanks again!

The ski parts expert at Wipline has been on extended leave for health reasons from what I’ve heard. I wish him well. His knowledge is missed.

Sounds like the rest are working from home so responses have been slower.

Tell him to get in touch with Steve Kracke at Atlee Dodge in Anchorage, and see if Steve can give him some assistance. Steve rebuilt my AWB 2500s from the ground up, and did a great job. Been some years, but.....

And, then, tell him to BUY some stuff from those guys, assuming they help him get things sorted out.

I have these on my 1955 170B with the hydraulic version. I can provide pics and assistance as needed. Email me with your needs: Nielsen at Bloomer dot Net.
