Over 140 people died on Tuesday when the Hercules C-130 exploded in a fireball shortly after take-off.
Agus Supriatna, Indonesian Air Force chief said that one of the engine's propellers was found in a position which indicated it was not working and rescue workers have now ended the search for victims of the crash.
The funeral of the plane's pilot, Capt Sandy Permana, was held in Semarang on Thursday |
Air Marshal Supriatna said the investigation team had recovered all of the plane's four engines and the abnormal propeller.
He said even though the other three engines were still functional it would have been impossible to control the plane as the problem occurred right after take off.
He told reporters the fact that the plane turned rightward and was flying at a lower-than-normal speed also pointed towards engine failure.
Witnesses on the ground said the plane was tilting and emitting black smoke |
'Paying passengers'
The aircraft was carrying more passengers than the military first reported. Authorities had initially only said that 12 crew members were on board the 51-year-old plane and did not mention passengers.
The number was then repeatedly raised, showing confusion about how many people had boarded and alighted during the plane's various stops at different cities.
