The ceramic thermal barrier coating has been damaged by pieces of debris hitting it. The debris came from a combustor liner that had begun to break up. We take a very close look at each of them to determine which need to be stripped and re-coated.
Liners normally are not subject to flame, but in these older engines, it sometimes happens. This cases burning and deterioration of the metal, and eventually some pieces may break off.
