Yes creamy the prop had little or no rotation.
This stop the rotation of the D.O.W.N switch locking device which lock the wheels in the U.P position. As the wheels where locked in this position it's unable to unlock the D.O.W.N activation of the switch.
Hence the wheels stayed in the U.P POSITION. How ever to remove the aircraft a slight rotation of the prop allowed the switch to unlock and the wheels came into the D. O. W. N. Position.
