What did this guy hit??

I saw this clip yesterday of an emergency landing. I'm curious to know
what this guy hit to knock off the left main? Looks like it was hanging
by the brake line. Obviously a slow day when a Warrior makes news by
sliding down the runway to an uneventful grinding halt.

....or the trailing link broke , allowing the strut pressure to push
the ram out of the mount...

We had the identical failure in an Archer at our field a few years ago. New
aircraft owner getting checked out by a 78-year old instructor who had been
flying since 1941. As they rotated they heard loud banging from underneath.
A low pass over the field confirmed the right main dangling from the brake
line. The crusty old instructor just took over and headed for Trenton where
they had better firefighting support. Somewhere along the way the banging
stopped. Lou put it down without incident, and with only a few scratches on
the wingtip. Unlike the guy in the video, he applied just enough brake on
the good main to keep it dead straight on the runway. No sign of the errant
strut and wheel, just a stub of the brake line left. Turned out the strut
seal retainer had blown out, apparently taking the scissors with it. I
guess it's not an uncommon failure. We never found the missing main gear.
Fortunately, it didn't end up in someone's living room.

He was my primary instructor. Never heard this story before, but I'd
heard others. He is one cool cucumber who knows how to fly!

Thanks for sharing.

Answer: If the bolt in the landing gear scissors comes out the strut
will come out and leave it hanging by the brake line.

Nope. If the bolt in the landing gear "scissors", aka the torque link,
comes out the strut will be free to turn and the wheel may no longer be
properly aligned, but that won't allow the strut to come out as it is not
holding the strut in.

I believe theat Stache meant the bolt at the center hinge of the scissors;
and I was thinking the same thing.

Peter you got it. I have seen this happen a couple of times. There is
a AD of Piper aircraft about this and a change in the service manual to
install a larger dia. bolt and nut.

If the bolt comes out of the scissores (torque link) the pressure will
blow the lower strut out of the cylinder.

That's what I thought he meant.

Not possible.
