The investigation team decided to investigate the crew 's motivation to deviate from the flight 's predicted flight path . They checked on the crew 's previous flight from Sentani to Oksibil . It was revealed that the crew did exactly the same thing : making a direct left base by deviating from its predicted flight path . Investigators then stated that the crew might have been overconfident with their flying skill . Similar to TransAsia Airways Flight 222 , due to their previous success on landing an aircraft prior to the accident ( by flying below the minimum safe altitude ) , the crew believed that they were able to do the same thing in the future without considering the consequences . The crew had accrued thousands of flight hours and were familiar with the airport . Because of their familiarity with the terrain , they tend to be confident with their skill . Thus , their situational awareness were reduced significantly
