Yyyeahhh. You'd think that would go without saying.
“ Duncan had given the jet’s primary captain a list of “experienced test pilots, for hire, to perform the post-maintenance stall test flight”, says the NTSB. “After being unable to coordinate the stall test flight with a test pilot, the flight crew elected to perform the post-maintenance stall test themselves.”
I don’t know how common this is,but in this case it was obviously a bad decision.
If they weren’t trained and certified to perform these tests and checks this should never have happened.
Very sad
