Executive Summary:The incident followed an uneventful Trans-Atlantic flight and approach to Runway (RWY) 24 at Shannon Airport. On landing, the aircraft bounced a number of times and the ground spoilers did not deploy. While the pilot applied maximum thrust reverse and maximum manual braking, complete deceleration was not achieved in sufficient time to stop the aircraft departing the end of RWY 24 and rolling some 230 ft into the grass over-run area. Once stopped, the aircraft commander shut down the engines and the aircraft was evacuated in an orderly fashion through the normal entry/exit doors. Consequently, the airport was closed to commercial operations until 1245 hours, when the aircraft was towed back to the ramp.

Causal Factors
The late selection of 50 flap destabilized what had otherwise been a stabilized approach, placing the aircraft in a position from which a normal touchdown and landing roll-out could not be effected within the remaining landing distance available.
