Dubai: The UAE General Civil Aviation Authority's (GCAA) ongoing investigation into the UPS Boeing 747-400 plane crash in Dubai on September 3, 2010 has regarded as unlikely the possibility of an onboard explosion.

"In addition, as per standard accident investigation protocol, following the retrieval of flight recorders from the Digital Flight Data Recorder (DFDR) and the Cockpit Voice Recorder (CRV), commonly known as black box, the GCAA investigation team has thoroughly analyzed the technical data and has concluded that there was no presence of acoustic evidence or any forensic indication supporting the detonation of an explosive device," GCAA said in a press release.

"The GCAA investigation into this accident will continue to determine the cause of the onboard fire and crash of the UPS aircraft," GCAA said.

The investigation teams are scheduled to return to the United States in three weeks to coordinate further investigation activities with Boeing and the NTSB as the cause of the accident is determined, GCAA added.
