Part 2/7:
At the controls were Captain Refri Widodo, a seasoned pilot with more than 13,000 hours of flying time, and First Officer Yoga Santo, who had accumulated around 4,000 hours. Both had gone through Adam Air’s training and appeared capable. However, Adam Air was notorious for its lax safety protocols and poor maintenance practices, raising questions about the preparedness of its flight crews.

In the months leading to the accident, the aircraft had displayed over 150 recurring defects, including severe issues with the Inertial Reference System (IRS), a pivotal component of navigation systems. The pilots knew about the IRS problem but were unequipped to deal with the systemic failures that would soon ensue.
