Malfunctioning devices was a “significant aspect” in the AirAsia plane crash last December that killed all 162 individuals on board, Indonesian authorities say.
The airplane’s rudder control system malfunctioned four times during the flight, officials said in a report.
The team’s reaction to the fault also contributed to the disaster, the report included.
The Airplane A320-200, travelling from Surabaya to Singapore, crashed into the Java Sea on 28 December 2014.
Private investigators had actually at first shown that stormy weather was a major consider the crash – however, they now say that this was not a cause of the crash.
The new report from the National Transport Safety Committee, released after a year-long investigation, discovered that the soldering on a tiny electronic part in the system that managed the rudder was cracked, causing it to send out four warning signals to the pilots.
The team aimed to fix the issue by resetting the computer system, but this disabled the auto-pilot. They then lost control of the aircraft.
The aircraft then entered “a prolonged stall condition that was beyond the capability of the air travel crew to recover”, the report stated.
Maintenance teams were aware of the problem as it had occurred 23 times in the past year, and resetting the system was among a number of methods used previously to address it, the report added.
The report likewise stated that:
– Inadequacies in the upkeep system caused “unsolved repetitive faults occurring with much shorter periods”.
– There appeared to be miscommunication in between the pilot and co-pilot – at one point, the pilot commanded “take down” however the plane was ascending.
– At another point, the two guys seemed pressing their controls in opposite instructions.
The report does not assign blame or liability, but is planned to assist the market prevent future accidents.
Eka Santoso, who lost numerous member of the family in the crash, told AFP news agency: “AirAsia needs to discover the people who were responsible for this problem [with the faulty element]”.
Those who failed to take care of the fault should be prosecuted, he added. “It has been proven there was a weak point.”.
Malaysia-based AirAsia’s President Tony Fernandes thanked private investigators on Twitter and added that “there is much to be discovered here for AirAsia, the maker and the aviation market”.
“We will not leave any stone unturned making sure the industry learns from this terrible incident.”.
Since the crash, AirAsia had performed 51 procedures to enhance safety standards, the report said.

Households of the 162 individuals on board AirAsia air travel QZ8501 have been waiting anxiously for the results of this examination.
Indonesian investigators did not release their preliminary findings previously this year, saying they were under no legal obligation to do so.
Covering the crash at the time, the working theory was that pilot error must have been a significant factor, or that bad weather condition was an aspect.
However this report shows that it was really the reaction of the crew to a chronically malfunctioning part on the airplane that triggered the airplane to crash which bad weather had nothing to do with it.
AirAsia will now have numerous questions to address about why the aircraft was not much better maintained and why its pilots were not better prepared to manage these issues.
