Here is a story similar, about a different person than the deceased from this thread.
A couple of years ago I received a call from a young Asian woman looking for tailwheel instruction, she was looking for something different to do while she was attending a pilot mill school in FL. We did two flights, and she left. She didn't finish her endorsement. After a week or two I called a friend that was working at her school and asked what her story was. Turns out that after one of her unsatisfactory stage checks she asked if a particular sexual favor would change the outcome of her stage check. The check airman didn't accept the offer, and she didn't pass the stage check.
Two or so years later, I have seen her in the FBO and heard her on the radio. She's a CFI now. As much as I would like to believe that she received remedial training and progressed through the ratings, I'm not naive and have a good idea of what happened.
