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. ________________________________ Message 2 _____________________________________ Time: 11:30:28 AM PST US From: "David Owens" Subject: Re: Commander-List: Orenda Rises Again Great, but will it be offered for Commanders???

Randazzo" Subject: Commander-List: Help Finding Part... 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. Robert S.

Ideally that eat Jet-A. Avgas around here is above $4/gal, Jet-A about $3.

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.

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.

Randazzo" Subject: RE: Commander-List: Orenda Rises Again 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?
