NOTE : Label (41) shows the assymetric offset value. This is the
____ adjustment applied to the forward eccentric bearing in the flap drive strut at tracks 3 and 4. The adjustment is necessary on some aircraft to give the correct aerodymamic balance:
-
a plus (+) value shows that the flap trailing edge must be moved up
-
a minus (-) value shows that the flap trailing edge must be moved down
