I imagine this could be an issue with many of the
Pawnees around.

Right, the aluminum static line is prone to cracking.
You can also see the ASI jump by opening and closing
the air vent when there's a static leak.

And of course some Pawnees have ASI on cockpit static...

Even without leaks the ASI will seriously over-indicate.

Unfortunately, lots of Pawnee pilots are not trained
about the issues in this thread.

Be careful out there,
