Decided to let it ride and not fix something that's not broken. Went out to hangar today (-7.at sunrise,) and spent a couple hours putting the elevators back on (all new hardware of course) I sure love squeezing in all those washers aside rod end bearings. Yeehah.

I'll put the VS on tomorrow and then make the rudder bottom fairing change to get rid of the snap bushing for the tail light and widen out a slot. Found too much chafing on the wiring.

In the meantime, it all gave me an opportunity to go over the the rudder, VS, and elevator with a fine inspection to get the progressive annual underway, I've been meaning to move it to too-cold-to-fly season anyway.

I'll plan on buying some HS parts from time to time over the years and slowly build a second HS. If the cracks appear, I'll just swap it out. the longeron attach point redrill isn't an issue. The shim makes a good drill guide .If I sell the plane, it'll be a relatively inexpensive A&P bill for the next owner.

Thumbs up

I'll add another one.

Inspected a friends RV-6A, low time since a TX rebuild after a flip-over.
New horizontal bought pre-built.

Low hours on the new horizontal -

No cracks seen, and the hardest part of the inspection was removing the tight fitting HS-VS fairing.

Who do we contact for warranty? I think that these being a homebuilt nobody had to say anything about this. Thanks to Vans for their integrity. The integrity now has to follow on with the owner. I'll look at mine when it isn't so cold and wet.

My count is 8 with Danny King being the first -8. I am making a list with hours to make a failure probability plot.

2-6's
4-7's
2-8

Considering 5000 planes flying this number is extremely low, not to mention the crack is a soft failure, and no incidents are known in the fleet. One would have thought the 6's would have more hours and be higher in the reporting, but not yet. The population reporting here must be quite limited. Surely it will unfold with time.

posts go too fast to update the count!!
