Reading the details in the accident report is rather interesting, in as much the hours logged by both.

So both are logging the hours, all we need to know in what capacity was each logging those hours. TCT is nominated as PIC on the report, so how is Ewald logging time? Ewald as PIC (instructor), TCT dual (student) is about the only means by which both could be logging time, as far as I'm aware, in a single engine that only requires a crew of one. Unless of course TCT was instructing Ewald, since she says she has an instructors rating in the report.
