Royal Air Maroc flight 200, a Boeing 767, experienced a hard landing on runway 04R at John F Kennedy International Airport (JFK), New York. There were no injuries to the 210 passengers or 10 crew members onboard but the airplane received substantial damage.
During the initial approach, the flight encountered gusty wind conditions (16 knots gusting to 24 knots). As a result, the flight crew added an appropriate wind additive to the reference landing speed (Vref). The airplane touched down in the touchdown zone approximately 1,600 feet from the threshold with a recorded normal acceleration (Nz) consistent with a "firm" landing. As the main gear touched down, a full nose down column was applied that produced a very high nose-down pitch rate, which resulted in a hard nose gear touchdown. The recorded normal acceleration at nose gear touchdown was 1.8 g, however, the actual load applied at the nose gear was much higher because the accelerometers are located in the main gear wheel well. The peak nose gear load experienced at nose gear contact exceeded the design-limit load by as much as 46%. The recorded normal and pitch accelerations, calculated data, and estimated nose gear loads confirm that the aircraft experienced a bending moment that exceeded both the design requirements and the structural capability of the fuselage.

Probable Cause:

PROBABLE CAUSE: "The first officer’s input of full nose down elevator at touchdown. Contributing to the accident was the gusty wind conditions."
