casa has looked at one of the blades now and tells us that not only has it delaminated on the bottom doubler but on the top as well even though we could not see it.
there has been only one defect report submitted to casa even though there are several instances of similar delamination. i have no idea why this is not reported by the relevant engineers even though the blades have been sent back to the factory for replacement.
casa is going to write to all operatotrs and explain the situation and get everyone to inspect their blades. we don't know if it will become an ad.
maybe it was one batch, maybe, just maybe. do they make batches?????
