PITOT TUBES...(6699)
From: Yves Starreveld <ystarrev@julian.uwo.ca>
Hi, All,
I am looking for a replacement pitot tube, but have not been able to find
one through standard sources. Is it a special item? Does anyone have one
they would be willing to part with? Also, I would like to install landing
lights, to be able to carry a passenger after dusk. Does anyone have drawings
detailing their installation in the wheel wells? Thanks in advance...

I do not know about dealing
with the CN MOT so I am not going to talk about pitot tubes other than
to say maybe it would be best to keeping looking for an original to avoid
paperwork problems. -- Steve Wilson <SteveWlson@aol.com>
Yves:
I don't know what difficulty you would have with your DOT up there in
Canada using anything other than a stock pitot. There have been numerous
different pitot tubes "field approved" in the US and I seem to remember
an STC'ed AT-6 type that came straight out of the leading edge - but don't
use that - it doesn't work! An AN5812 mounted on a length of streamline
tubing about 15" long will work, but I don't know about the approval.
See the aircraft catalogues. I had one of those on N2334B and it was very
accurate. -- Jim
NO AIRSPEED FOR YOU! (AUG 03)
Subj: Air Speed Indicator
From: Dave Jewell <jewell.jewell@verizon.net>
Jim,
I want to replace my air speed indicator and I called a well know instrument
shop in the mid-west to get a price on a certified air speed. I was asked
for the pilot operating handbook so he could put the speed markings on
the instrument. I told him that there was no pilot operating handbook
for the Swift, and at that point he questioned whether the Swift was a
certified airplane. He told me his FAA person would not sign off the certification
of the instrument unless I provided documentation for the speed indications
and it needed to come from some official document when the airplane was
originally certified. He also explained that his instruments are built
to the same standard, whether certified or not, and if I wanted an uncertified
instrument that he'd be glad to send one. Do you have any thoughts on
this? By the way, would you have any idea where I could find an original
set of yokes. Someone painted mine with some kind of black plastic material
and I'd like to have the original color back. -- Dave Jewell N1948J

Simply go to the Swift Web Site and print the Aircraft Specification A-766
which is the Type Certificate. It has all the required numbers there.
Level flight or climb 140 mph (122 knots) Glide or dive 185 mph (161 knots)
Flaps extended 90 mph (78 knots) Back in 1946, they didn't require the
stall speed to be marked but the manufacturer advertised a 48 mph stall
speed. Regarding the yokes, I think you can strip and sandblast them,
then repaint them. -- Jim
STATIC PORTS... (JAN 04)
From: Jim Montague <Swift31B@aol.com>
Subject: Swift static ports
Denis
I had a question by phone and I had to look up the answer so I said "email
me." I never did hear back but here is the answer.
Q. What location works best for the static ports?
A. A letter from Temco dated Dec. 10, 1952 states "Location of static
port. The most satisfactory location for the static port is at fuselage
station 122, vertical location optional from center line of fuselage to
3" above." Charlie Nelson sent me the letter which they had
on file in Athens. I tried to get the FAA to use it as acceptable data
but ran into a stone wall. They want a test installation and a full flight
test with certified instrumentation. I know there are field approvals
out there so if someone would send me a copy of their 337 form I might
be able to do something. A 337 form dated before 10-01-55 is considered
approved data. If we had one of those it would be great! If anyone has
the static ports relocated and a 337 dated before 10-01-55 PLEASE let
me know immediately! -- Jim
