Lion Air Flight 904 was a scheduled domestic passenger flight, flying from Husein Sastranegara International Airport in Bandung to Ngurah Rai International Airport, Bali, Indonesia. On 13 April 2013, the Boeing 737 operating the route while on final approach crashed into water short of runway. All 101 passengers and 7 crew on board survived the accident. The aircraft involved was a Boeing 737-800, registration PK-LKS, operated by Lion Air between Husein Sastranegara International Airport in Bandung, Indonesia and Denpasar. At 15:10 local time (07:10 UTC), the aircraft crashed approximately 0.6 nautical miles (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.

The airport was closed for around ninety minutes while emergency services attended the scene.At the time of the accident, Lion Air had 16 other Boeing 737-800 in the fleet.

Investigators published the final report and concluded that pilot error was the cause of the crash. The investigation determined that there were no issues with the aircraft and all systems were operating normally. The investigation concluded several factors to this accident were the pitch angle versus engine power on the FDR data indicated that the basic principle of jet aircraft flying was not adhered during manual flying, aircraft flight path became unstable below MDA when the rate of descend exceeding 300 metres per minute, in which this situation was not recognised by both pilots, and the Captain's decision to go-around was conducted at an altitude which was insufficient for the go-around to be executed successfully. The flight crew loss of situational awareness in regards of visual references once the aircraft entered a rain cloud during the final approach below minimum descend altitude (MDA), thus, the plane crashed into the water.

Aircraft

The Boeing 737-8GP, registration PK-LKS, was officially owned by Avolon Aerospace. The aircraft was received new from Boeing by the Lion Air subsidiary Malindo Air on 21 February 2013. It was then transferred to parent Lion Air on 20 March 2013. The aircraft had been in service for less than six weeks with Lion Air before the accident.

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 metres (466 ft) AGL. The report found that at 270 metres (890 ft) AGL, the first officer reported that the runway was not in sight. At approximately 46 metres (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 6.1 metres (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 during 2014.

Passengers

There were two pilots and 5 flight attendants with 101 passengers on board consisted of 95 adults, 5 children and 1 infant. The passengers were mostly Indonesian, but included one French, one Belgian, and two Singaporeans.
