You have to perform a stall test after any wing maintenance. What’s the logic behind that requirement?
And you have to hire a test pilot to do that test? Wow.
It’s shocking two experienced pilots could not handle the stall in ideal test conditions. How could they have handled a stall in normal biz jet operation with passengers?
At a minimum to test the Stall Warning System which was likely disconnected and reconnected as part of the maintenance, but may also have had certain components replaced.
