Indonesia relies heavily on air transport to connect its thousands of islands but has a poor aviation safety record and has suffered several fatal crashes in recent years.
In August 2015, a commercial passenger aircraft operated by Indonesian carrier Trigana crashed in Papua due to bad weather, killing all 54 people on board.
Lion Air, a low-cost airline, has been involved a number of incidents.
Last year one of its Boeing jets collided with a Wings Air plane at Kualanamu airport on the island of Sumatra, although no one was injured.
In May 2016, two Lion Air planes collided at Jakartaâs Soekarno-Hatta airport, while a month earlier a plane operated by Batik Air â part of the Lion Group â clipped a TransNusa plane.
In 2013 a Lion Air jet with a rookie pilot at the controls undershot the runway and crashed into the sea in Bali, splitting the plane in two. Several people were injured in the crash, although no one was killed.
Last year the Indonesian air traffic controllers association revealed that the rate of take-off and landings in Jakarta allowed by state-run air navigation company AirNav was more than the airport could handle, increasing the chance of accidents.
