Runway surface conditions are emerging as the prime suspect in the overrun of an Airlink Embraer ERJ-135 at George, South Africa, two months ago.
The aircraft was badly damaged after it failed to stop after touching down on 7 December.
While South Africa's civil aviation authority says the investigation is still continuing, Airlink believes the ERJ-135 was not at fault.
"From the facts available to Airlink extracted from the aircraft's flight-data recorder, it would appear that the landing accorded with Airlink's specific wet-runway operations procedure," says the carrier.
Airlink chief Rodger Foster adds that the aircraft's systems "functioned normally".
George's runway 11/29had been resurfaced during the month before the accident, and investigators are assessing whether this - combined with rainfall at the time of the jet's arrival - contributed to the accident.
