It's nice to see it outside with a prop on it!

The issue was a bit of grease in the left mag. M20Doc fixed while I waited this morning.

So I'm looking at the engine data from yesterday's flight and all the egt's seem to be fluctuating: Where as my flight the day before looked like this: I've asked Savvy to do an analysis, I'll be interested to hear what they say.

Cool, do you ever come back this way?

Very nice!

I did try a couple of mag checks, but each time I just missed the "event".

While flying today I noticed occasional rpm fluctuations, rpm would drop by about 25 and bounce back. I don't believe it's an indication error as I heard it first which drew my attention to the tach. I then noticed that when these fluctuations were occurring, the #2 EGT was fluctuating as well. It would rapidly rise by about 100F and drop back down. These fluctuations would happen over a minute or two and then everything would be normal for a while before happening again. I eventually switched from LOP (my normal cruise setting) to ROP and I didn't notice anymore rpm fluctuations, but I didn't watch the egt too closely so I'm not sure if they stopped too. I'm heading back out to the hangar to download the engine data and upload to Savvy. Any ideas what might be going on?

And yes, this is a forever plane

Thanks Carusoam. I believe the insurance company is covering the cost of replacing the one blade and I pay the balance for anything above. The extra for any option is manageable. The estimates for the options come from the prop shop that Clarence uses, they are of course reputable. The prop is 12 years old, I don't know off the top of my head how many hours are on it but it has been overhauled once (2 years ago). If I go the Hartzell top prop route, they are estimating 2-3 weeks. I of course would like to be flying sooner than that, but if it's an upgrade, maybe it's worth the wait?

So I have three options: - replace the damaged blade and have it ground down to match the damaged blade (I'm not a fan of this option) - replace both blades - replace the prop with a Hartzell HC-C2YR-1BFP/F7497. (Existing prop is a McCauley). Help! Should I go with the Hartzell? What are the differences? Is there any weight difference? Performance difference? Thanks, any advise will be appreciated! OW

Surprisingly I felt no vibration in flight. I was completely unaware of anything wrong until seeing the chunk missing from the blade.

The engine will require an inspection.

Insurance is covering it. Prop is 12 years old and was overhauled 2 years ago.

This morning I was making the short flight over to the M20Doc's shop for some minor maintenance. When I arrived, I was still sitting in the airplane organizing my things when Clarence walked out and I heard him gasp - my heart almost stopped, I looked up and saw what he was looking at, a good chunk missing from my prop. On departure my prop must have picked up a pebble, I've seen many small dings in props before but nothing like this.

My J has over 7,000 hours on it, I've had it for the last 3 years and almost 300 hours. So far I'm very happy with the airplane and have had no major issues - and no it's not for sale :). @M20Doc has been looking after it, both currently as well as for a number of years before I bought her, so I think that helps!

Clarence usually brags about his eight cylinder Comanche, since he forgot to do that in this thread and since I've had a few winter time rides in it, I can tell you that it has no trouble pumping out heat.

From Dynon's certified Skyview FAQ's, in answer to the question "Do I need to install the full system?" Their answer is: "Dynon will have a variety of system configurations available to tailor an installation to your aircraft. This may include omitting some products that you choose to not install." Hopefully this will be true...

Merry Christmas Clarence, see you next week. And Merry Christmas to the rest of MS.

If you'd like to log an hour or two in a jet warbird, go see Larry in Santa Fe, NM at http://www.jetwarbird.com/. I flew an hour in the L-39, it was awesome (but not cheap)!

Mine burns a quart every 4 hours. Cylinders have been borescoped showing no issues, compressions are good, oil analysis also good, it just seems to be what the engine consumes. Engine has 1,100 his since new and I've had it for the last 250 hours.

Should you happen to depart CYSN after FSS hours (they close at 9:00PM local), London FSS has an RCO on the field so you can reach them on 126.7 and they will relay an IFR clearance for you.

Oddly enough, I had forgotten about this. My fuel pressure readings have remained consistent ever since and I completely forgot about it when the annual came around, so I didn't have it checked.

Me too please!
