An Indonesian transport safety committee blamed the pilot of a Garuda airliner for the crash of a Boeing 737 crash at Yogyakarta airport in March that killed 21 people.

The committee's report said the aircraft with 140 people 'was flown at an excessive airspeed and steep flight path angle during the approach and landing, resulting in an unstabilised approach'.

'...the pilot in command did not follow company procedures that required him to fly a stabilised approach, and he did not abort the landing and go around when the approach was not stabilised,' the report said.
