Will be interesting to know if the T/R D/S bolts were checked at the G/B flex plate. The T/R shaft has a number of rotational scores/scratches just forward for the flex plate mount as does the interior of tailcone bulkhead at the upper inspection hole. While I don't agree it was given a "clean bill of health" due to the requirement of a check flight, there are still a number of questions left unanswered at this point. And just as discussed in the Bahama Cline 139 accident, yet again we have another pilot who defies logic, plus the actions of the previous pilot, and loads his family up for a maintenance check flight. As the rotor turns....
