YOGYAKARTA - The pilot of an Indonesian passenger jet that crashed last year, killing 21 people, has been charged with deliberately causing the disaster when he appeared in court.

Marwoto Komar, a former captain with Garuda Indonesia is charged with three counts of negligence and one of "deliberately" destroying or damaging an aircraft causing death over the March 2007 crash of the Boeing 737 with 140 people on board in the central Java city of Yogyakarta.

The charges carry a maximum sentence of life in prison.

The hearing was adjourned until August 4 when the defence will get a chance to reply.

AFP reported that Komar's lawyer Muhammad Assegaf said his client would fight the charges on the grounds that international civil aviation codes rule out criminal liability for pilots in crashes.

"We will at the very least question why the pilot is being criminalised for an accident. This has not yet happened anywhere in Indonesia or in the world," Assegaf said.

"Punishing the pilot would give rise to fears among pilots that one day they could be treated as a criminal over an aircraft accident," he added.

"It's impossible that a pilot could do this deliberately."

An official government report in November found Komar ignored 15 automated cockpit warnings not to land as he brought the plane in at roughly twice the safe speed, causing the jet to bounce and career off the runway and burst into flames in ricefields.

Komar was sacked by Garuda in February and has had his pilot's license suspended.
