MONTY THE ANSWER
STEVE WANTS TO
ASK JUST ONE MORE QUESTION...
My Swift has Stewart-Warner engine gauges installed. These gauges are
sold by Aircraft Spruce but are not what are considered "aircraft" gauges.
They look like and perhaps are more an auto gauge. They appear in this
photo of my panel as the four chrome gauges on each side of the navcom.
Are they "legal" and appropriate for this Swift? Again, I have people
telling me I have to change them out to be "legal". Sorry for so many
questions. Regards, Steve N2397B
The Swift, like a lot of light planes had non-TSO'ed engine instruments.
The original oil pressure, oil temperature, fuel pressure and ammeter
are automotive style gauges. If a 3 in 1 gauge or other AN gauges are
installed they ARE TSO'ed and only require a log entry. Using Stewart
Warner type gauges is open to some interpretation. If I were relicensing
the airplane I would consider them equivalent to the originals, and ignore
them. If I were making an original installation of a reworked panel with
them installed, I would submit a form 337 for a field approval. Why
don't you ask Don Bartholomew? He might give a different slant on this.
Don't apologize! Hey, I love this stuff! -- Jim

Subject: Westach EGT / CHT
From: Ed Lloyd <firstname.lastname@example.org>
Hi Jim, been awhile. I have run across a new six cylinder, manually selectable,
EGT / CHT system by Westach on the net that is for sale at less than half
price. Unit still in original box and has six thermocouples and rotary
selector with it. Do you have any experience with this system at all.
Almost seems to good to pass up. If I had a system similar to this, I
may have saved a cylinder overheat awhile back. Thanks.....Ed Lloyd
That system should work OK, but the Westach is an "economy"
instrument and I don't know if they are all PMA'ed. I had a Westach EGT
guage on an airplane and always thought it read high, but you just want
a comparative number anyway. You are installing it for supplemental use,
so getting a field approval should be relatively easy, if it's not a PMA'ed
instrument. -- Jim
