If he is referring to the TAC assessment, there are even more problems.

TAC examined Max Hunters SSX design, not DC. Their main complaint about
turnaround was the active cooling being used in the Thermal Protection
System (TPS). They felt (with good reason) that the complex tubes and
pumps needed for this would make access difficult.

However, since DC doesn't use active cooling, most of the TAC complaints
regarding maintenance are moot.
