My question would be has the wing frequency test ever proved anything?
I'm aware of two cases where it has picked up significant structural problems in a wing that were then found with more detailed inspection. I know of another where the change was quite drastic (30% change between annuals), but has been unable to identify the cause to date and the aircraft is still grounded. There is also one case where it didn't (Bathurst's DG300 that delaminated the spar caps from the wing didn't pick up a freq change, but the tap test did).
