AN26, vicinity Cox’s Bazar Bangladesh, 2016

Summary

On 29 March 2016, an Antonov AN-26B which had just taken off from Cox s Bazar reported failure of the left engine and requested an immediate return. After twice attempting to position for a landing, first in the reciprocal runway direction then in the takeoff direction with both attempts being discontinued, control was subsequently lost during further manoeuvring and the aircraft crashed. The Investigation found that the engine malfunction occurred before the aircraft became airborne so that the takeoff could have been rejected and also that loss of control was attributable to insufficient airspeed during a low height left turn.

Description

On 29 March 2016, an Antonov AN-26B (S2-AGZ) being operated by True Aviation on a non scheduled domestic cargo flight from Cox’s Bazar to Jessore, reported an engine failure immediately after takeoff and an immediate return was requested. After two discontinued approaches the crew subsequently lost control at a low altitude and were unable to recover before impact with the sea surface which destroyed the aircraft and caused the death of three of the four flight crew on board and serious injuries to the other one, the Navigator.

Investigation

An Investigation was carried out by the Bangladesh Aircraft Accident Investigation Group (AAIG). Both the FDR and the CVR were both recovered from the aircraft in an apparently externally undamaged condition and both were subsequently taken to the Ukrainian National Bureau of Air Accident and Incidents (NBAAI) for readout. The FDR data were successfully downloaded but the CVR data could not be recovered because of internal damage to the equipment. The recorded ATC communications with the aircraft were also available and a transcript was made.
