  1. I just bought a Jabiru 2200, that shows a log book recorded factory overhaul about 200 hours ago. The seller said the engine ran great 4 months ago when the repair hangar (across rom his hangar) upgraded the previous owner's (not the seller) CH701 to a Rotax 100hp for more thrust, and then the repair shop sold the engine to the guy who ultimately sold it to me this last weekend. This seller claimed he saw the engine run strong 4 months ago, he bought it for himself, and then he changed directions and now sold it to me. The motor (so he said) sat in a hangar under a plastic tarp-like cover. When I bought the motor, I did not do any compression or other internal checks (go easy on me here) In faith I took his word on it. We both had military background, and I hope he would not fleece me like that.
    Now, yesterday, as I was checking the motor out in my garage, I looked at the plugs (they looked good [light tan electrode insulators] but they seemed to have a lot of friction in the threads), and then I pulled them out to check the cylinders. I will share those pictures later if I can. One of the cylinders had what looked to be oil passing the porcelain on the plug. There also seems to be oil residue need these plugs (see picture). I did not see this on the other cylinders. Note: all of the plugs looked the same on the inside (light tan). Looking into the cylinder in question, I turned the crank 360 degrees, and looked inside the cylinder with a scope. I found some white flaky material in the cylinder (small amount). I was able to move the white material around with a small screw driver while observing with my scope. Note: the tops of all of the pistons looked the same (I will post pics later). I did not observe this flaky residue in the other cylinders. Now, the motor was sitting for 4 months (I was told), and the muffler wan not attached (just the header runners were attached). Perhaps some bees or mud dobbers made a nest in there depositing clay.?.  But, what about the oil looking residues near the plug holes and the blow by on the plug.?. I may have to pull the head, for further inspection, but I am looking for experiences and thoughts here.

    Hello Ladies and Gentlemen... and the rest,
    I'm new to the Avid Flyer and, honestly, a new pilot (less than a year licensed). I am in the process of buying a Mk4 w/ EA-81 Subaru near Tyler, TX. I was hoping to find some help in this venture as well as link up with local (Houston, TX area) Avid/Fox flyers. The plane looks okay to me, but a problem would have to be pretty obvious to be caught by such an inexperienced eye. Optimally, I would like to find someone with experience with Avid Mk4s to give her a look (I'd be willing to pay for services, of course). Otherwise, does anyone have a good checklist to use when considering a purchase? Thanks in advance for all your help and I, very much, look forward to being a part of this community.

  4. Does any one here have a good picture of the wing lift strut end that attaches to the fuselage not painted. Folding wings back and noticed crack in paint. Chipped paint away to look closer and it looks like there are two tabs on the lower and top flange that sandwich the fuselage attach lug.  Just want to see if this is normal construction and if these are 2 steel plates together. I wonder why would they not be welded together or do I have more to worry about? First post, little history of the Airdale flyer I have. Built by my father  and finished in 2002.  He passed away 3 years ago and kept plane in family. Just about 900 hours on the airframe so needing to keep a closer eye on her as she ages. Enjoying all of the 100 hours I have flown in this aircraft.



  5. Here is the inside of one of my engine cylinders, using a TV borescope: 130  hours since new, 42 with 100LL, the rest with Mogas. Comments??
