CRACKS...(DEC 02)
Subj: Windshield Cracks - there's always something!!!
From: Jeff Wimmer <jwimmer@fleetweather.com>
Hi Jim & Denis:
Got N78276 back from the paint shop on monday - Everybody that has seen
her so far just drools! (Film going in for developing today - will get
to Denis in a few days.) I flew her back from the shop on monday, and
she seems to have picked up at least a few miles per hour. Will let you
know more when I get a little more experience. Yesterday during the calm
before the storm (got about 4" of snow last night) I took her for
a short flight to begin to get reacquainted. As I was flying, all of a
sudden I noticed two small cracks on the pilot's side lower edge of the
windshield. One about 1" long maybe 5" or 6" to the left
of the center. And another about 1/2" long maybe midway between the
center of the aircraft, and the end of the windshield on the pilot's side.
When closely examined, there seems to be a slight deformation in the plastic
at the end of each crack. I can't say whether they were or weren't there
when the plane went in for paint - so I haven't said anything to the paint
guy yet. Maybe they were, and I just never noticed them. Maybe they happened
when the canopy was installed last January, as there may have been some
stress put on the windshield when the gull wing canopy was installed.
The history of this windshield is that it was installed when I bought
the plane in June of 2001, and yes, the holes for the screws were drilled
very oversized to give it room for expansion and contraction. The canopy
was installed in January of 2002. If they stay the way they are, I can
live with the cracks, especially with that nice new paint job that I don't
want to mar by changing it. What I don't want to have happen is for the
cracks to get any worse. So.....here's the question: In your experience,
what is the best thing to do, or NOT to do? I went straight to my mechanic
when I noticed the cracks yesterday, and his advice (given to him by people
who maintain helecopters which apparently get LOTS of cracks in the plastic)
is to take a very fine sewing needle, heat it red hot with a propane torch,
and pass it thru the windshield at the end of the crack. Later the small
hole can be filled in with some clear plastic silicone, if necessary.
He says that works better than stop-drilling which can leave rough edges
which can start new cracks, and the hole is smaller. I asked him whether
I should just wait and see if they grow before doing that. He thought
that was a good plan of action, and suggested that I either measure the
cracks, or mark the ends with a grease pencil. Your thoughts? Best regards,
Jeff Wimmer
Jeff
BTW - I just got my Vintage Airplane today -- nice article! Of course,
we Swifters had seen it in the Internet newsletter. That idea of a hot
needle and some clear plastic filler sounds good to me. I have not used
them, but I understand there are repair kits now for repairing plastic
windshields. I had a car which had a rock chip in the windshield and the
dealer repaired it for about $50 and you could not see any sign of the
repair. I think they use a plastic filler and polish it out. It seems
to me I have seen those windshield repair kits advertised in Trade-A-Plane.
Maybe someone will read this and give more info. I've always just stop
drilled cracks, then replaced the windshield before the next annual. Cracks
almost always are from too small screw holes or screws that are too tight.
Of course, if whoever who trimmed and installed the windshield left some
stresses in there......it will tend to crack. If there is vibration or
a blow to the windshield, it will crack further. I would relieve pressure
by loosening the retaining screws. You don't want them tight at all. I
think there are repair kits for completely filling holes. -- Jim
WINDSHIELD REPAIR KIT?
(DEC 02)
From: Jeff Wimmer <jwimmer@fleetweather.com>
Went thru my Trade-a-Plane (First November Issue) cover to cover, checked
the classifieds too. No ads for windshield repair kits that I could find.....Maybe
somebody out there in Swift electronic-newsletter-land will know what
is available, or will have researched this issue further. -- Jeff
1001 USES FOR VELCRO... (WELL, AT LEAST HALF OF IT.) (FEB 03)
From: "Doc Moore" <darladoc@sport.rr.com>
Subject: Pin Ups
Hi Denis: I just keep pluggin' along and eventually, one of these days,
it'll be flying again. I've got the wings on, the outboard tanks plumbed,
etc. Am still hanging control surfaces. Its all coming out better than
I expected. Finished my upper hatch and am now cleaning the window rails
and re-doing them. Have replaced all the side window glass, polished and
painted the window metal, and the windows are ready to go back in as soon
as I do the upper tracks. Found out that the soft side of Velcro makes
a great channel liner for the glass to slide in. Buy the stufff at Wal
Mart with the adhesive backing, cut it in 3/4" strips and put it
on the inside side of the channel. Gives .080 glass a snug fit but they
still slide okay. -- Doc
ONE PIECE WINDSHIELD STC... (APRIL 03)
Subj: One Piece Windshield
From: Doc Moore <darladoc@sport.rr.com>
Jim:
I installed a replacement one piece windshield that I obtained from LP
Aero. I have no record except a log book entry for the one piece unit
I removed. Would you happen to have a copy of an STC for the one piece?
I apologize for bugging you for paperwork so much but I'm close to flying
and am trying to get my paperwork in order. Thanks, Doc
Doc
The STC for the bubble windshield is SA4-403; held by Aircraft Windshield
Co. 3762 Catalina St. Los Alamitos, CA 90720. I have no idea if they are
still there. If they are defunct and not supplying the STC, the FAA may
grant a field approval. I don't have a copy of the STC in my files. They
also hold STC SA4-761 which I believe is a version with a modified windshield
frame. Curiously, the address on the second STC is 3842 Catalina St. Many
of these windshield were installed in years gone by without the owners
bothering to buy the STC and no 337 was ever executed. Now the STC holders
have gone broke and the paperwork is not available. See a moral here?
Maybe if Denis publishes this some California reader knows if the STC
is still available. Jim
(Editor says... Doc found that the address above is no longer current.
According to Doc, here is the most current address: Aircraft Windshield
Co 10871 Kyle St., Los Alamitos, CA 90720-2410 Phone:(562) 430-8108 )
IS RIVETING EXPERIENCE REQUIRED TO INSTALL SIDE WINDOWS? (AUG 03)
Subj: Side Windows
From: Bob Price <bobpriceswift@aol.com>
Jim:
I am about to install new side windows (the ones that move up and down).
I do not have any experience with riveting..could I use pop rivets or
small bolts or other fasteners? The existing windows have "bucked"
aircraft rivets. Also, are seals located at the bottom of the frame still
available? Thanks Jim!......... Bob P
Bob
It sounds like you have some modified windows based on the original design.
I don't think Swift Parts has any parts for the original windows. If the
windows are riveted in the frames it is nonstandard and nonstructural
so small screws or pop rivets might possibly be used. -- Jim
DUANE WOULD LIKE TO KNOW... (SEPT 03)
Subj: Blue Glass
From: Dorothy Golding <dotgoldswift@mail.ev1.net>
Hi Jim;
Duane would like to know where he can get the blue glass for the plane
he is working on it is supposed to be .090 but he does not seem to be
able to locate that thickness. He can find 1.25 in town. -- Dorothy
Dorothy
We have gotten the original type blue glass thru LP Windshields in PA.
You may have to order thru Aircraft Supply (800) 569-9397 You want to
get the glass formed because if you use flat sheet it will craze prematurely.
The originals used a light blue, LP seems to think the FAA requires a
dark blue which you can hardly see through. I had to sign a release the
last time I got some. I don't know if you can get or even want the .090
thickness. It seems to me we got .100 or .125 for Mick Supina's airplane.

REAR WINDOWS...(JAN 04)
From: Jeff Wimmer <jwimmer@fleetweather.com>
Subject: Re: Janaury #1 GTS Internet Update
I really MUST look at my data plate on the aircraft to see what year it
thinks it is. According to the FAA records, it is a 46. According to the
serial numbers on the site, it COULD be one of those with a funky number
in the year of manufacture. I hunted around on the site.....but couldn't
find the explanation for the different rear windows - I probably read
about it in the 50 years of the Swift. Was it the Globe manufactured birds
that had the wrap-around one piece windows? Do ALL the Temco Swifts have
the 2 small rear windows? Thanks for any info!!! Regards,Jeff
Jeff
All the Swifts manufactured prior to s/n 3561 had the "Globe"
style rear windows. The Temco Swifts after s/n 3551 had the "new
look" D windows and the flat shelf. But there are exceptions! The
first Swift with the flat shelf was N78225, s/n 2225. In addition the
Temco factory converted many Swifts to the flat shelf, some before they
were ever sold. And if a Swift was repaired or refurbished by the Temco
factory in the late '40s it probably got the "new look" installed
too. For example, N80866 s/n 269 had the "new look" rear windows
and flat shelf installed by Temco in 10-48. When Temco sold the type certificate
and all the spare parts for the Swift to Vest (Univair) in the 50s one
of the most popular sales items was the "new look kit". There
were two kits available. The S-130 had the flat shelf and D windows but
retained the "A" frame turnover structure. The S-131 had the
Temco heavy bulkhead turnover structure. I remember "back when"
it seemed really cool to have the later "new look" and I ordered
an S-130 kit from Univair and installed it in N80539 in the '60s. You
do get a little more interior room with the flat shelf, but nowadays I
think the Globe rear windows look better. I don't think I'm alone on that
because I know of many Swifts that have been converted back the earlier
style. Of course, the canopy equipped Swifts mimic the outline of the
Globe rear windows. -- Jim
More from Jim on s/n 2225...
N78225 was one of the Swifts manufactured in 1946 as a Globe Swift but
made by Temco. I believe all or most of the s/n's prior to 2225 were sold
in 1946. N78225 was retained by Temco as an experimental airplane to try
out new modifications, and was fitted with a spin chute for some time.
The patches from the removal of the spin chute can be seen on N78225 to
this day. N78225 was made originally with the slope shelf and Globe rear
windows but was changed over some time before the Spring of 1948, it was
on the front cover of Flying Magazine in May, 1948. I think all of the
2000 s/n's had the slope shelf and Globe style rear windows. I have a
Temco factory photo from 1948 which shows N78296(?) at the Temco plant
and you can plainly see the bigger Globe style back windows as well as
some other Swifts, new, but with the older style back windows. A similar
photo can be seen on the Swift site. Click on Globe Temco Swift History
- then Globe and Temco Factory Photos - on Page 2. the first photo is
very close to the one I'm refering to. -- Jim
SPEAKING OF REAR WINDOWS...(JAN
04)
Subj: rear windows
From: Mark Oltjenbruns <moltjenb@bellsouth.net>
Hi Jim ,
It looks like its time to replace the rear plexiglass windows , I have
a hairline crack about 1 1/2". I found some plexiglass .118 thick
thats almost an exact smoke tint match . I see that Mark Holliday says
use a unibit for drilling .The question is how do I bend it ? some say
an oven or use a heat gun . I can make a form to match the bend of the
window . Any suggestions appreciated. Happy New Year , Mark Oltjenbruns
Swift 78311
Mark
It will actually go in without being pre formed, but if you do that it
will craze prematurely. I suggest you bend it to the approximate curvature
and heat it in an oven or if you can't find one that big, a big box with
a heat lamp. If you were using the regular light blue tint I would suggest
Aircraft Supply (800) 569-9397 but I understand you want the gray tint.
If you use a form, I believe they cover the form with felt or some soft
fabric. -- Jim
