On 25 December 2016, a type-experienced ATR72-600 Captain bounced the aircraft twice nose gear first whilst attempting a night landing at Semarang and during a third bounce on the right main gear only, it collapsed. The aircraft drifted right and after two further bounces began to decelerate and came to a stop. The Investigation found that after a normally-flown approach, the aircraft had not been flared and effective recovery action had not followed the bounce. It was concluded that the Captain had been subject to a visual illusion which had distorted his perception of height above the runway.
