Sounds like the pilot should've been asking questions long before this flight. Expired straps, reused hardware when installing parts, no documentation, half filled out logbooks, negative component times on the paperwork...
... as a relatively inexperienced pilot, I guess he possibly didn't know any better - or if he did, he still would've been hard pressed to walk away from a turbine job.
I hope the new pilots reading this report can learn something from that.
