The nose landing gear of the Airbus A320-200 was jammed, but the tires were perpendicular to the fuselage. How did that happen?

    $\begingroup$ Slightly off topic, but serious kudos to the pilots for a picture (video) perfect landing - straight down the center line! There was surprisingly little damage to the plane, though I'm sure the nose gear got a thorough going over. $\endgroup$

According to the complete NTSB report, following is a summary of what had caused the nose landing gear (NLG) to rotate 90° on Flight 292.

During flight, Brake Steering Control Unit (BSCU) performs1 cyclic tests which slightly rotates NLG from the 0° position. Due to this fatigue, two of the four anti-rotation lugs on the NLG upper support assembly fractured and separated. This allowed NLG to deviate from the 0° position. Another contributing factor was BSCU system logic, which prevented NLG from centering. Also contributing was the lack of a procedure to attempt to reset the BSCU system under these conditions.

This website has some nice pictures of nose landing gear before and after the landing.

A summary of the investigation can be found here.

1: BSCU has other functions too.
