Détails:
Caribbean Airlines flight 523, a Boeing 737-800, was destroyed when it suffered a runway excursion accident after landing at Georgetown-Cheddi Jagan International Airport, Guyana. One serious and multiple minor injuries were reported among the 157 passengers and six crewmembers on board the plane.
The flight departed Port of Spain, Trinidad & Tobago on a scheduled flight to Georgetown. The aircraft was cleared for an RNAV (GPS) approach to runway 06 at Georgetown. This is a 7,448-ft / 2,270-m long asphalt runway. There were no reported anomalies in the en-route profile, although during the descent the aircraft deviated to avoid some thunderstorm cells north and east of the airport. The reported visibility was 9000m. Light rain was encountered during the approach.
The pilot reported that after visual contact was made and after crossing the Final Approach Fix (FAF), he disengaged the auto pilot and configured the aircraft for landing. The flight was normal until the aircraft was approaching the runway. Even before the aircraft was over the threshold, the captain commented that he was not landing here.
As the flight continued over the runway, comments on the Cockpit Voice Recorder (CVR), revealed that the captain indicated to the first officer that the aircraft was not touching down. A go-around call was made by the captain and acknowledged by the first officer, however three seconds elapsed and the aircraft subsequently touched down approximately 4700ft from the threshold of runway 06, leaving just over 2700 feet of runway surface remaining.
Upon touchdown, brake pressure was gradually increased and maximum brake pressure of 3000psi was not achieved until the aircraft was 250ft from the end of the runway or 450ft from the end of the paved area. The ground spoilers were extended on touchdown. The thrust reversers were partially deployed after touchdown. The aircraft did not stop and overran the runway. It went down a slope, impacted the ground and came to rest across a road.

Probable Cause:

CONCLUSION: The probable cause of the accident was that the aircraft touched down approximately 4700 feet beyond the runway threshold, some 2700 feet from the end of the runway, as a result of the Captain maintaining excess power during the flare, and upon touching down, failure to utilize the aircraft’s full deceleration capability, resulted in the aircraft overrunning the remaining runway and fracturing the fuselage.
Contributory Factors:
The Flight Crew’s indecision as to the execution of a go-around, failure to execute a go-around after the aircraft floated some distance down the runway and their diminished situational awareness contributed to the accident.
