Circumstances:
En route from Tambaram to Hyderabad, while in cruising altitude, the captain declared an emergency and informed ATC about the failure of an engine. Shortly later, the aircraft entered an uncontrolled descent and crashed near Dubagunta, killing all 22 occupants.
Probable cause:
It was determined that an engine failed in flight and later detached, causing the separation of a wing. The failure of the high compressor disk was the consequence of fatigue cracks that were not detected during the last maintenance inspection.
