The report says on the approach the ground proximity warning system sounded 15 times, and the co-pilot called for the captain - the pilot flying - to go round. It says the captain failed to follow company procedures that "require him to fly a stabilised approach", and he should have gone around. There is no evidence the pilot-in-command was physically or mentally impaired, says the NTSC, adding that he ignored the warnings because he was "fixated" on landing the aircraft. According to the report the co-pilot also failed to follow the Garuda operation manual, which states the co-pilot is to take control of the aircraft and execute a go-around when an unsafe condition exists.
