Indonesia's transport ministry will be conducting a "special audit" on Lion Air, following the crash of one of its Boeing 737-800s into the sea near Ngurah Rai International Airport in Denpasar on 13 April.
"We will look at how the airline operated the aircraft involved in the incident, the airline's safety management system, plane maintenance and also the training of the crew," a transport ministry spokesman told Flightglobal Pro.
"This is separate from the National Transport Safety Committee's investigation. The DGCA [Directorate General of Civil Aviation] will take corrective actions with the findings."
He adds that the audit will start "in a few days", and is likely take up to a month to be completed.
Both the aircraft's flight data recorder and cockpit voice recorder have been retrieved and sent to Jakarta, where the analysis will be done.
Investigators are, however, still trying to move the wrecked aircraft on to land. Work is still being done to cut up the two-month old 737 into several segments to facilitate its removal from the shallow waters near the airport.
The Lion jet was on a scheduled service from Bandung to Denpasar when the incident happened on the afternoon of 13 April.
The authorities initially said the aircraft overshot the runway before hitting the sea but Lion later clarified that the aircraft had crashed about 50m (164ft) short of runway 09.
The carrier's two pilots have been grounded pending investigations.
