ED'S EXCELLENT RESTORATION
ADVENTURE...

Good morning.....thought I would give you an update on my Swift restoration.
I have the panel removed, wiring harness from rear of firewall out, fin,
rudder, elevators and stabilizer are also removed. Found corrosion on
the false bulkhead that the trim assembly is bolted to. It looks like
an uncomplicated repair. Could find no evidence of further corrosion in
the tail (that's good). This morning I have a pressure washer and I am
taking it outside for a complete wash job, inside and out. I found out
how old I am (45) when I had to crawl inside the fuselage to the rear
bulkhead and hold the wrench to remove the four front stabilizer bolts.
Can you two think of anything else I should be looking for? Thanks for
your input, Ed Krause
Ed,
It sounds like you have a pretty good handle on where to look for problems.
The tail is the first place to look for corrosion. At 45, it was EASY
to crawl back in the fuselage and under the instrument panel. Now at age
60 its getting tough! Keep in touch! --- Jim
CONCERNS WITH A 50+ YEAR
OLD AIRPLANE... (010400)
Subject: Restoration
From: Keith Bracht <kab_bjb@skat.net>
Too windy to fly today, gusts to 60kts in the area. So us hanger flyers
started talking about fabric vs. aluminum. One fellow believes that any
airplane regardless of skin material should have the skin removed at least
every 20 years just to see what's going on underneath. I got to thinking
that 29K still has most of its original skin except where a couple repairs
were done along the way. Neither I nor Paul Nyenhaus have found any corrosion
or cracks. So what do you think? Do I need to start planning for a restoration
in the future?
Keith,
Any airplane should get inspected annually, with maybe a little more thorough
inspection every few years, but not to the extent of deriveting the skin
of a metal airplane! If they had just chromated the Swift structure internally
corrosion would not be such a factor, but as it is there are enough inspection
panels for an inspector to find any incipient corrosion. Some of the control
surfaces don't permit much of an internal inspection but when rivet heads
start popping off, its time to remove an end rib or drill a hole for a
closer look at the innards. The control cables on a Swift can be inspected
very adequately, unlike some brand "C" or "P" airplanes which need one
end of the cable unbolted and the cable pulled out of the airplane to
inspect it. Many "rag" airplanes have wood structure, which may require
a close look. I feel comfortable inspecting the 50 year old structure
of the Swift because we know where cracks are likely to occur and where
corrosion might exist. I have been spraying the structure of the Swifts
I annual with LPS-2 or 3 for the past 10 or 15 years. There are some other
products on the market such as ACF-50 which do a good job too. -- Jim
FOUND AUTOMOTIVE UNDERCOATING
USED INSIDE CABIN... (010400)
Subject: Coating
From: Larry La Force <LaForce55@aol.com>
I am currently removing a coating that is inside 80844 that appears to
be similar to automotive undercoating. It is cracked and peeling pretty
bad. I figured with everything out of the fuselage... now was the time
to do it. My question is ... was this coating in all Swifts? If so ...
would you recommend reapplying? Thanks.... Larry LaForce
Larry:
I have seen that stuff before. I see no reason to reapply it. I think
the idea was a sound deadener - I don't think all Swifts had it. Nowadays
we rely on headsets more than anything to save our ears. -- Jim
