I will repeat my prior assertion that the rudder trim was displaced during the accident breakup sequence. Let me ask you all to consider the significant climb rate of a King Air with two engines operating and the gear remaining down. Now you have that picture in your head consider the photographic evidence showing the actual, much reduced, climb rate of the accident aircraft. There is no doubt in my mind that this was power lever migration and unfortunately it wasn't recognised by the pilot flying. It is a travesty that the ATSB have missed a golden opportunity to educate the King Air pilot community to a latent killer.
