Well it must have over 250 flights on it and the firewall finally came loose.
I was landing into a headwind and had just killed the engine, then at the snap of your fingers the wind died.
It ran off the end of the runway and the muffler snagged a clump of earth, it stopped so suddenly that it flipped upside down.
I was busy checking the V tail area, for that's a weak point and I thought it was unscathed, but I wrenched on the engine and I could move it down.

I pulled the engine mounting plate and loaded up some used insulin needles with CA and injected the glue into place. That worked like a champ.
