More information was revealed Tuesday about AirAsia 8501 that lost contact soon after taking off and eventually went down killing all 162 people on board last December.

One of the Airbus A320-200's parts had been faulty for a long time, and crew action toward it led to the crash, according to multiple reports.

The plane, which left from Surabaya, Indonesia, and was headed to Singapore went off the radar 40 minutes after taking off, according to the BBC.

The incident happened on Dec. 28, 2014.

A cracked solder joint malfunctioned four times during the flight and 23 times the previous year, according to mytimes.com.

"Subsequent flight crew action resulted in inability to control the aircraft," investigators said.
