That damage is what’s caused by tying these airplanes down with chains. The chain is impossible to get really perfectly tight, as a result there’s always a bit of slack. In a wind, the plane comes up against the end of the chain with a HARD stop. Which bends things, and those are the parts that bend, and break. This has resulted in fatalities.
NEVER tie these airplanes down with chains, folks. And carefully inspect these parts on any plane you’re not very familiar with. After a fatal accident in Alaska, these parts on the Cub I was flying were found to be severely bent, and one was cracked. The last guy who flew the plane had tied it down with chains……in Kodiak.
Take a really good look at these parts.
