Orenda Rises Again
A Midland, Texas, company has received FAA approval to take over the engine
type certificate for the Orenda OE600A, a Canadian-developed, 600-hp V-8
based on a big-block Chevy engine. The granting of the type certificate
transfer from the former Canadian owners allows Trace Engines to begin
shipping engines, including the 10 finished mills it inherited in the
takeover of the project. Two engines were shipped, ironically, to Canada
last week and are expected to be flying by the end of the month. The Texas
plant won=B9t likely build its first engine until September. "Because this is
a start-up, we have the opportunity to do things right the first time,"
spokesman Craig Hoover told the Midland Reporter-Telegram. "We have an
active research and development program. There are things we want to improv
e
on the engines even before we begin production." The big recips are aimed a
t
replacing far more expensive small turboprops on a variety of light and
business aircraft. They were developed about 20 years ago in Canada, but
despite gaining certification were not widely installed. Hoover said his
company aims to change that and he expects a lot of foreign orders. There
are 12 people working at Trace now, but plans are to increase that tenfold
and incorporate a college training program into the factory.

Commanders-
Does anyone have a lead on the rudder gap heating element for a 685/690
commander?
Part number is: P/N 5E1487-2.
The one we have is pretty severely delaminated- and as far as I can tell
nobody overhauls them... We found one available for sale but they want
$3,400.
Ideas? Help? All appreciated.

Sure be nice if someone offered an affordable replacement for the
GO-480/GSO480 engines. Ideally that eat Jet-A. Avgas around here is
above $4/gal, Jet-A about $3.

After reading the thread about those heavy geared engines, this should
really be a nice revival.

| Subject: | Re: Servo Failure |
Well I was going to email the Bendix servo article out to anyone that wanted
it, but after having to use a chainsaw, tow strap and my truck this morning
to get pine trees out of the way to get to work after this last Nor'easter,
I think up in Vermont we're going to be without power for a while. I did put
it on our company's Downloads page, under Bendix.zip.
http://www.col-east.com/index.php
Let me know if anyone has any trouble with zip files. I'll check messages on
Tuesday.

Folks,
At the risk of pouring cold water on a good news story, there were
some good engineering reasons why the Orenda program went very quiet.
I really hope the new Type Certificate holders overcome the problems.
Last time I noticed, the only Orenda powered Commander was still
being advertised for sale as an Experimental aircraft, the STC was
presumably never completed.
Cheers,
Bill Hamilton

Bill-
As a 685 owner- the Orenda project has obviously come across various
google
searches I've made... I got the impression from reading around the
various
pieces on the internet that the project died on account of funding
issues...
Can you offer any insight on what the engineering reasons were?
