What is Oil Canning? How is It Spotted? What Problems Dose It Cause? Dose It
Affect Airworthiness? If So How Is It Resolved or Fixed?

We experienced this in our Arrow a couple of years ago. It would
occur usually after landing while parking the aircraft. A gear
collapse many years ago hadn't been repaired quite robustly enough, so
we had it reinforced and that took care of it. On any a/c with damage
history, I wouldn't ignore it.
