Turbo flying

[gammaxy]

Tried to drain oil from crankcase w new filter system in place. NO LUCK no oil drain when I opened nut on the bottom.

Sounds like you are describing the same problem I had the first time I changed the oil after installing the mini sump. I was quite surprised/panicked when I removed the plug and oil didn't immediately come pouring out :-) You should be able to disconnect the oil line to the sump to drain the oil. The mushroom-shaped rubber seal is too thick or the wrong shape for the filter and forces the check valve to press against the bottom of the mini sump so oil can't drain to the plug. After discovering the problem I modified mine so there is a bit of clearance from the drain plug. This thread has more information:

I don't have the turbo so I have no advice about the high oil pressure.

I have over 35 hours on my turbo. I see 85 psi oil pressure on start up, and 65 - 75 psi in flight after the oil gets warm. Oil temp 175 on a hot day. As far as draining the oil. I use the return line on the side of the sump. Oil will only trickle out the drain plug. Sounds to me like your system is operating as expected.

Hello Everyone:
Does anyone know if I have to notify FAA FSDO that I now have a Turbo powered Sonex? Will I have to re-enter Phase I testing?
Thank you

Jack,

By all accounts, adding the turbo should be considered a major alteration and would require a notification to the local FSDO for re-entry into Phase 1. Before you call them though, read your Operating Limitations. The only thing the FSDO technically needs to do is approve the testing area for your Phase 1 testing.

You'll most likely need at least a 5 hour Phase 1. Good luck!

Not only is the turbo a major change but the big thing my FSDO was hung up on was the prop change. They told me that alone would trigger a return to phase 1. They said to send them a letter (snail mail) with the changes and proposed test area and testing time. I requested 35 miles centered on my home airport and 5 hours in phase 1 which they approved. Took about a week to get the approval letter back.

Jack, the previous responders have it right (at least if your operating limitations (OL) read the same as mine) that your turbo and prop change will require a reentry into Phase I for additional testing.

But my question for those who may know is........if Jack already has an "approved test area", is there any real requirement to notify the FAA at this time since the OL only require an approval of the test area planned to be used and Jack may already have that from his earlier Phase I testing? In my case, I had moved and therefore had no "approved test area" at my new location when it came time to test some new props........so contacting the FSDO was necessary for that approval.

For sure, Joe Norris would have the answer to this expanded question and maybe he will chime in if he is still monitoring this list.

Yep, changing the prop to a different make or model is a major change all by itself. Also, the horsepower upgrade by itself would be a major change as well. So the two together is a major-major change!!

As for the test area, technically once the airplane is signed out of phase one that test area approval is done with. Even if you're still in the same place, you should follow your operating limitations and get the area approved again. Such are the ways of the FAA!

I followed the instructions of the local FSDO which was to send a letter listing the modifications made and request a return to phase one for X # of hours (I said 5) and define my proposed test area. My original test area was 25 n miles. This time I asked for 35 which added another emergency airport and it was granted.

I wouldn't be shy asking for as big of a test area as you wish. My original was 40nm. After talking with my FSDO, I probably could have gotten 50+. Since you're already flying, I'd recommend making it big enough for some good airports for emergencies as Bill said in his post.
