An Alitalia MD-11 passenger plane, registered I-DUPO, was damaged in a landing incident at Chicago-O'Hare International Airport, IL (ORD), USA. There were no injuries to the 14 crewmembers or 253 passengers.
The airplane was cleared for and flew an instrument landing system (ILS) approach to runway 22R, at ORD. The pilot flying was the first officer. He flew the airplane throughout the entire approach and landing on runway 22R. He had been flying for 10 hours and this was the only landing he made during the flight.
The airplane experienced a hard landing on initial touchdown. Subsequently, the nose tires failed, damage occurred to the general area of the nose landing gear support structure, and there was foreign object damage to the #1 and #3 engines. The flight data recorder (FDR) data indicated that the initial touchdown acceleration had a value of 1.9488 g's. Also, the fdr revealed that after touchdown, the airplane experienced four oscillations in the pitch axis. The maximum pitch angle during this time was +5.98 degrees nose up, and the minimum value was -2.46 degrees nose down. During this time frame, spoiler positions never exceeded 8.0 degrees of deflection and the nose weight on wheels parameter changed four times.

Probable Cause:

PROBABLE CAUSE: "The first officer's improper flare and improper use of flight controls during the landing flare/touchdown."
