Indonesia will not publicly release the results of a preliminary investigation into the 28 December 2014 crash of an Indonesia AirAsia Airbus A320 aircraft.
A preliminary report will be produced by late January, 30 days after the crash, but widespread media reports cite Tatang Kurniadi, chairman of the National Transportation Safety Committee (NTSC), as saying that it “will not be exposed to the public".
"This is for the consumption of those countries that are involved,” Kurniadi adds.
His comments also indicate that the report will not contain any analysis about the crash of flight QZ8501, which claimed the lives of 162 passengers and crew.
Flightglobal was unable to reach Kurniadi for clarification on the matter, and the possible schedule for the release of data to the public.
In separate statement on the NTSC’s web site, Kurniadi says the investigation into the incident is being conducted by a 34-person team under the observation of French and Australian monitors.
Kurniadi also vowed that the investigation will be neutral, with investigators not to be swayed by other parties, such as the police or prosecutors.
The announcement that the preliminary report won’t be made available to the public comes one day after Indonesian transport minister Ignasius Jonan told the country’s parliament that the aircraft climbed at 6,000ft/min and then descended 7,900ft in the space of 45s before contact was lost.
The aircraft’s crew had requested a climb to 38,000ft from its assigned altitude of 32,000ft, while in the vicinity of poor weather, during the service to Singapore on 28 December 2014.
The reasons behind the rapid climb are unclear.
Indonesian authorities have said publically that cockpit recordings derived from the aircraft’s cockpit voice recorder suggest that terrorism was probably not a factor in the aircraft’s crash into the Java Sea.
