View Full Version : Bad end to a good day

Had a bad end to a fly in breakfast we attended this weekend, the gusty weather showed up a few hours early and greeted me with a nice 16G22 crosswind. Carried some extra speed into the flare and tried to get the into wind main down first but caught a gust that blew me sideways off the runway. Went to go around as I was rolling through the grass but didn’t get the climb I was hoping for at 36 degrees and I was headed right at the control tower terminal and warehouse just north of the runway. Decided to just shut it down and try and stop it. Ending up rolling onto a neighbouring taxiway where the right main caught the edge and folded up going about 20-30MPH. My son was excited to see the fire trucks, I was not. Looking for advice on repair ideas and suggestions. I’m in owner maintenance in Canada and can use experimental parts/ non stcd pieces.

let me know your thoughts!

I am sorry to see that!
Looks like your decision making was good and your son has a great attitude - way to see the bright side! What a memory!
One day you may smile looking back.
It is a strong point of our sturdy birds - they can be fixed and returned to service.

Go to ebay right now. This morning I saw a set of wing struts up for bid, no bidders and about a day left for $100

Hi,

Sorry to see these. You'll also find the step and exhaust flattened too, hopefully easy remedies. I see the prop tips are gone too, you think you'll be opening the engine as well?

The struts mentioned above seem to be very reasonably shipped too, a touch over fifty bucks.

Still waiting for a reply from my insurance company, it had a brand new whirlwind on it with 5 hrs and the blades just sheared off, regardless I’ll be opening the engine up and doing the prescribed lycoming inspection. Exhaust is crunched but might just be the lower portion, we’ll see. Going to look at it better tomorrow.

thanks for the info on the struts, I’ll find some sealed units while it’s down for repairs.

Dang! Wonder if Eddie Trimmers PA20 gear reinforcements could be used on PA22 gear?

Im wondering the same thing, it’s a 58 pa-22 with the univair conversion. I wonder if the trimmer legs would fit the mounts. The trimmer conversion on your account pane looks great! At $1800/leg the trimmer STC makes great sense.

Mark is thinking the tube brace mod that Eddie has done on a lot of -20 and -22 conversion gear legs... Welds in a tube mid point of the streamline tube to midpoint of the rear main tube... The PA-18 gear STC is a completely different mounting that requires lots of welding in the airframe.

Since you are basically experimental with the owner maintenance I would be tempted to look into the TK-1 gear as seen here https://store.tk1racing.com/ProductDetails.asp?ProductCode=PACER1.. Its a bolt on installation with the cabane system, would be stronger than the Univair system.

Mark,
I looked at Eddie's website, and the only landing gear STC was for converting a PA-22. Can you point me in the right direction for the reinforcement STC?
Gracias!

Not an STC… Field approval only… have been able to get it on a couple but don’t know if it could be done again now days..

Brian, any documentation? I sent an email to Eddy and haven’t heard back. I’m assuming it’s just a reinforcement on the gear legs?

I have the 337’s that I have done… and one of the airplanes is in storage on my field that I can get good pictures of…

The way I’ve done them is by follow on approvals using a copy of a couple 337’s Eddie did…

Brian pictures would be great, still deciding if I have the bucks to spend on the shock monster gear or the strengthened univair gear.

thanks!

This is a Univair gear with the support tube mod and gussets at the axle… also did a weld on fuel step..

Just to note… I did not do the welding in these… One of the owners has a fabrication and welding business.. Way better welder than I will ever be..

I’ll have to did out the 337’s when I have the time..

As I understand it, the added cross tube will mostly help with buckling of the streamline tube when the gear is sideloaded toward the centerline of the plane. This gear looks like it failed in the opposite direction. The LPC service letter to add gussets at the top of the streamline tube seems likely to have been more helpful here. It would be very nice to see picture of the attach point at the top of the streamline tube.

If I remember correctly hydrosorb area of the gear leg is weak. Think most of the load is under tension on a piece that’s about 0.90” thick and maybe 3/4” wide. That piece sticking up... might be a good idea to add gussets to that area as well. Mine failed because the weld quality was chit! No penetration.https://uploads.tapatalk-cdn.com/20210715/12406028ada114145efe6bf598df979d.jpg

This PA-16 leg failed in compression, but the same issue contributed, poor penetration of the gusset welds.

Hi,

Kind of goes along with things.

JVader's gear failed the rear tube when he hit the lip of the taxi-way. I did the same thing in my Clipper years ago when I hit a small sand dune, compressed the rear tube and that was all she wrote.
