Have there been any cases of post mod flaps failing?
I see this as marketing from the 'fix' manufacturer.
No doubt the original design was weak - the spindle had aspects of it's design that were not good (inviting fatigue issues) from the photos I saw of failed flaps - but having redesigned this part, surely they fully solved the problem. Very surprised if not.
