In turboprops, the Shorts 360, the Dash 8 and the Q400; crabbing, then converting to wing-down/crossed controls at about a mile or two out seemed the best way to me.
On heavier aircraft that were also jets with underslung engines, crabbing right down into the flare and then gently pushing* straight with rudder just before the mains touch seems best.
Broken rudder control?
This ATP did not appear to put in any rudder during the flare. Would love to know why. A control fault or restriction of some sort perhaps?
* note: pushing, not "kicking". No control should be kicked or moved violently.
