I arrived this afternoon and was greeted by Frank Williams . Some faces on hand are Orestes, Josias, Paul , Howard , Wes, Eric , Frank McMillin , Joe and all their lovely wives. I have to report one wash out- me. My new take- apart parted with the outboard wing in a square eight, flight four for me today. It sheared just outside the mounting hardware. Not a hardware failure but an airframe stress failure of the 3/8 sq. spars. I'm being goaded to fly a borrowed ship so Rich Oliver is enroute with a backup. Hope I can keep this in one piece. Frank Williams also offered me one of his ships but I wanted to use my engine which isn't a good drop in fit (PA .75 to RO Jett .76) so we opted for one of Richards.

Could you post a close up of the break? I'm wondering what actually broke, and how one might prevent it if one were to build a take-apart.

Yes Tim I will. It's back in the car right now but I'll get it out in the morning.

Seems to be in the air, as it were. Looking forward to hearing the progress and results.

Here is a close up. It sheared right where the ply web ended.

Thanks Dave. I'm not sure what would have kept that from happening. It's a sobering picture, to be sure.

Carbon tows top and bottom of spars. Tapered ends to the plywood instead of a stress riser square end.

Yeah, I agree completely with this statement from Bill! Especially with the landing gear in the wing, it opens the potential for some prior damage at that spot due to rough landings etc. Not that I think Dave would ever have a rough landing... Carbon is cheap insurance in the center section.

Really sorry Dave...loss of a good airplane is always like losing a friend.

Incidentally, It's possible to mount a PA75 in ROJett mounting hole pattern by slotting the rear mount holes in the PA to 18 mm on center. In other words making the rear mounting hole in the PA approx .117 longer to the front. I've done it myself.

A couple of flat washers under the mounting bolt head keeps the bolt from loosening under vibration.

Mike Greb · « **Reply #12 on:** October 08, 2015, 07:37:46 PM »

Saw a plane at the nats that had that kind of a failure. Trying to use lightweight wood in small sections for spars is asking for trouble.

. Hi Randy. Frank , Richard, Joe and I chewed on it but Richard told us we'd have to slot the back holes of my RO Jett and being as my fortunes here are diminished, I couldn't see grinding on the engine. Rich is meeting me here with one of his this morning and I can just drop what I have in and learn to fly it. I'm not seeing any engine damage so that much I should understand today. Haven't checked the pipe for leaks but I've got an extra with me. Just wish work and weather would have allowed me more practice the last couple weeks- this would have happened at home and I'd have brought a one piece ship. I think a couple near- misses with a wing mounting that cracked loose the first few flights and a screw that came out in flight a few weeks ago likely did some unseen damage before what happened yesterday.

Dave_Trible · « **Reply #14 on:** October 09, 2015, 05:16:01 AM »

I took this one the day the screw came out.

I've seen this movie. This last year's when I left a screw out. Old timer's disease

Hi Dave,
Sorry, I guess I must have misunderstood what you said in your original post. I thought you had a PA75 and wanted to install it in an airplane that was drilled for a RO Jett. Apparently it's the other way around (You have a RO Jett engine) and that is more difficult and risky in my opinion. Still possible but things get a little thin at the rear of the mount. I don't think I would do that either.

I hope you can get something in the air to fly. Richard certainly has some good flying stuff!

Dave, I'm surprised you didn't have a back up plane with you. Tough about the wing separating like that as it looked good while you were flying here. By the way looks like you have a tougher group to fly with. Anyway you all have fun this weekend.

EddyR · « **Reply #19 on:** October 09, 2015, 02:00:54 PM »

Bill's Junar,is that the one with 3500 flights on it.

Randy Powell · « **Reply #20 on:** October 09, 2015, 03:17:46 PM »

I guess Paul, Howard and Orestes don't count as "tough competition".

It was a hard afternoon of practice for all in the 93 degree heat. Tonight most gathered for socializing and dinner at Watsons grill. I had the pleasure of sharing conversation and fine food with Riley Wooten , Gill Causey and spouses.

and you think youve got problems !

Sorry to hear the aeroplane snapped .

At least it looks like a enjoyable meeting .

Dave_Trible · « **Reply #24 on:** October 10, 2015, 11:01:56 AM »

We are at the mid point/ lunch break here. Each has two scores on the board and two to go. The wind got pretty sporty this morning but is starting to lay down and get hot. I didn't see a forecast but would guess we'll be in the low 90s. Here are a couple shots during lunch.

Thank You Gordy! We are flying thanks to Richard but I'll have to live to fight another day. I'm still getting my money's worth !!!

I'm glad that Richard was able to bail you out. It is a shame that you lost your plane.

Thanks for the pictures, we would be lost without you. It hurts not being there since I know almost everyone.

How many contestants are there?

Tom I think it was said 17 entries.
As far as the Junar I just looked in and it's a PA- I think maybe the .51. I have Billy's new one but he still had one he ran and I think this is it.

fred krueger · « **Reply #45 on:** October 10, 2015, 01:02:12 PM »

I believe Chris is running a PA .61 in the Junar.

I just asked Chris and indeed it is a .61 in the Junar.
Circle 2 is done and Dave Fitzgerald just landed on 3. Josias will go then all qualifying rounds have been complete. The scores are coming very fast so we'll have results soon.....
