Investigation number:
Status: Completed
Investigation completed


On 02 April 2003, a Bangladesh registered McDonnell Douglas DC-10-30, S2-ACR, was climbing through 2,700 ft following departure from Chittagong - Patenga Airport, Bangladesh when the No. 1 engine failed. The EGT exceeded 1,000ºC and the engine was shutdown. The aircraft returned for an uneventful landing.

The flight data recorder (FDR) was recovered from the aircraft in April 2003. The Civil Aviation Authority of Bangladesh (CAAB) was responsible for investigating this accident and appointed an investigation committee which included the aircraft operator. The CAAB requested ATSB assistance in the recovery of data from the FDR. The Executive Director of the ATSB approved the request. The CAAB also requested that some of the investigation committee be present during the download and recovery procedure. To protect the information supplied by the ATSB to the CAAB, the operator and investigation work undertaken to assist these agencies, the ATSB initiated an investigation under theTransport Safety Investigation Act 2003.

In 2007, due to the continuing uncertainty of attendance by the Bangladesh representatives, the ATSB downloaded the FDR to enable its return to the operator. A factual report describing the recorded data found on the FDR was prepared and provided to the CAAB.



Released in accordance with section 25 of the Transport Safety Investigation Act 2003.
