Default Latest Update

I apologize for not having an update recently...this is due to the fact that there was no new information available.

As of today, we have it on good authority that the Type Inspection Authorization (or TIA) has been issued. This means that the FAA has approved our proposed flight test plans and has given us the go-ahead to perform the official certification tests.

We plan to perform these tests as soon as possible. There are a number of variables at this point that will affect scheduling, but we will provide another update once testing has been completed.

Thank you all for your patience.

Default September 2008 update

C177RG owners:

A version of this update just appeared in the CFO Digest in time for the 40th anniversary of the Cardinal.

Dear Cardinal Flyers:

Our congratulations on the 40th anniversary of the Cardinal aircraft. I’m sorry we couldn’t attend, but we are hard at work on the C177RG exhaust as well as some other exciting products (not for Cardinals.)

Here is an update on the C177RG tuned exhaust program.

Earlier this month we completed all the testing requested by the FAA TIA. Those reports have been written and are now submitted for the FAA review. All indications are good and that we might just have the STC real soon.

In the meanwhile, we have been flight testing a 1975 C177 RG with the tuned exhaust on it to verify our performance numbers. So far, the exhaust is meeting or exceeding the results we saw with Phil Fisher’s aircraft. This particular aircraft’s engine is only 50 hours since rebuild by Lycoming, so it gives us a good indication of what a fresh engine can do with an optimized exhaust system. I hope to have some performance numbers to post onto Power Flow’s forum next week.

The final production tooling is being made and our jigs are being conformed to our drawings. So, while you won’t get a definite time commitment out of me yet, everything looks promising.

Tyler has been our data taker on this latest series of flights and he has posted some blogs onto our forum describing his experience. He had never gone on a true performance test flight with the aircraft – so his fresh perspective may be of interest to you.

Our forums are located at: www.powerflowsystems.com/forum.

Enjoy Wichita!
