I actually have heard of Univair (though not being a bug smasher pilot I perhaps don't pay close enough note to all the Pawnee related stuff) - I think that's who made our new struts. I was under the impression that Univair didn't necessarily do all the Pawnee parts, and that some still came from the Argentinian mob (whose name still escapes me). Maybe the Argentinians only provide paperwork - i.e. the type certification and the flight manuals ? I will never truly understand the bankruptcy, dilution, re-birthing and combining of companies in the aviation industry - sigh !
One second point to note - all your e-mails are "time shifted" back in the past. If you look at the thread below, you will notice that my e-mail was sent at 12:18am on Friday 31st, but your reply to it was sent at 12:51am on Thursday 30th. Better check your computer's clock and time zone settings ...

Jason Sounds like you troops haven't ever heard of Univair in the US? And parts they make under FAA PMA approvals & STC'd kits of parts for the PA25-150 and PA25-235, -260. You can get most everything you need that is of special nature for the Pawnee structure from Univair. The rest is standard steel tube, aluminium, nuts and bolts, cable, etc. OK it will cost, but the notion that you can't maintain a Pawnee airframe into the future for decades for lack of key structural parts is nonsense. You can make fabricated structural steel attachment clusters.Yes, corrosion in steel tubing is a hassle with aging Pawnees. But at least the Pawnee has decent wall thickness with most all its steel tubing elements. With steel tube framed ultralights the weight reduction is often at the expense of wall thickness. The AUF magazine a year or so ago highlighted the hassle with corrosion in a certain Lightwing with very low hours. Yes, I agree we have a towing launch cost problem & I would like to replace Pawnees with durable cheaper tugs. ...... Enough for now.
