A Caribbean Airlines Boeing 737-800 that overran the runway in Guyana and then broke into two had apparently landed long, said a senior official involved in an investigation into the 30 July incident.
Flight crew of the aircraft, registration 9Y-PBM, did not report any problems to air traffic control at Cheddi Jagan International airport before attempting to land, said the official, who spoke on condition of anonymity.
"From all indications, it appears that it [the aircraft] landed long," he added.
There were no fatalities in the incident, in which the aircraft fuselage broke into two.
Reports following the incident said the aircraft's flaps were retracted at the time of landing, but the official declined to confirm this.
Guyana's Civil Aviation Authority is leading the investigation, with help from the US National Transportation Safety Board. NTSB officials have returned to the US with the aircraft's flight data recorder and cockpit voice recorder for analysis, said the official.
Guyana's CAA has invited the Caribbean Aviation Safety and Security Oversight System (CASSOS) to assist it in the investigation. The grouping is made up of CAA officials from the Caribbean states of Barbados, Guyana, Saint Lucia, Suriname and Trinidad and Tobago.
