What is Lion Air Flight 904?

Lion Air Flight 904 was a scheduled domestic passenger flight from Husein Sastranegara International Airport in Bandung to Ngurah Rai International Airport in Bali, Indonesia. On April 13, 2013, the Boeing 737-800 operating the flight crashed into water short of the runway while on final approach to land. All 101 passengers and 7 crew on board survived the accident. At 3:10 pm, the aircraft crashed approximately 0.6 nmi (1.1 km) short of the seawall protecting the threshold of Runway 09. The aircraft's fuselage broke into two and 46 people were injured, 4 of them seriously.

Investigation

The Indonesian National Transportation Safety Committee (NTSC) published a preliminary report on 15 May 2013. Flight data showed that the aircraft continued to descend below the Minimum descent altitude (MDA), which is 142 m (466 ft) AGL. The report found that at 270 m (890 ft) AGL, the first officer reported that the runway was not in sight. At approximately 46 m (151 ft) AGL, the pilot again stated he could not see the runway. Flight data showed that the pilots attempted to perform a go-around at approximately 6 m (20 ft) AGL, but contacted the water surface moments later. The captain's go around decision came far too late. The bare minimum altitude for a 737 go around is 15 m, as 9 m of altitude is lost when executing the manoeuvre. There has been no indication that the aircraft suffered any mechanical malfunction. A final report was published in 2014.

In January 2017, Budi Waseso, the chief of Indonesia's national narcotics agency, said that the pilot of Lion Air Flight 904 was under the influence of drugs at the time of the accident, and had hallucinated that the sea was part of the runway. That claim is at odds with the statement made after the accident by Indonesia's transport ministry, which said the pilots had not tested positive for dr*gs.

The NTSC concluded that the flight path became unstable below minimum descent altitude with the rate of descent exceeding 1000 feet per minute. Analysis of the pitch angle versus engine power based on the flight data recorder "indicated that the basic principle of jet aircraft flying was not adhered during manual flying." The flight crew lost situational awareness and visual references as the aircraft entered a rain cloud during the final approach below minimum descent altitude. The Captain's go-around decision and execution was conducted at an altitude which was insufficient for it to be executed successfully. The pilots were not provided with timely and accurate weather information considering the weather around the airport and particularly on final approach was changing rapidly.

Injuries

There were two pilots and 5 flight attendants with 101 passengers on board consisting of 95 adults, 5 children and 1 infant. 97 passengers were Indonesians, one French, one Belgian, and two Singaporeans. 6 of the crew were Indonesian while one came from India.

The captain was 48-year-old Mahlup Ghazali, an Indonesian national who joined Lion Air in 2013 and had logged 15,000 hours of flight experience, including 6,173 hours on the Boeing 737. The first officer was 24-year-old Chirag Kalra, an Indian national who had 1,200 flight hours, with 973 of them on the Boeing 737.
