"From the (flight data recordings) so far, it's unlikely there was an explosion," Hananto said. "If there was, we would definitely know because certain parameters would show it. There are something like 1,200 parameters."
The final minutes of the AirAsia flight were full of "sounds of machines and sounds of warnings" that must be filtered out to get a complete transcript of what was said in the cockpit, said Hananto, who has been an air safety investigator since 2009.
The first half of the two-hour long cockpit voice recording has been transcribed. That includes audio from the previous flight and the beginning of Flight QZ8501, which crashed around 40 minutes after takeoff.
The team, which is working with French, Singaporean and Chinese air safety investigators, hopes to finish transcribing the recording this week, Hananto said.
With seven computers and various audio equipment, the small NTSC laboratory dedicated to the AirAsia investigation is split into two rooms; one for the cockpit voice recorder and the other for the flight data recorder.
Analysis of the flight data recorder would take longer, Hananto said, because investigators were examining all 72 previous flights flown by the aircraft.
Investigators hope to finish a preliminary report on the crash early next week. The full report could take up to a year, but will not include the entire cockpit voice transcript.
"In Indonesia it remains undisclosed," said Tatang Kurniadi, chief of the NTSC. "Just some important highlights will be included in the report."

Nurcahyo Utomo, another investigator from Indonesia’s Transportation Safety Committee, said nothing heard on the audio recording so far suggested pilot suicide played a role in the crash.
“So far we’ve managed to transcribe only half of it because there are so many noises,” he said. “We hope to complete it in a week.”
