On 11 June 2014, an ATR 72-600 sustained substantial damage after hitting an object after touchdown at Surabaya but was able to taxi to post-flight parking. The Investigation found that several sizeable items of equipment had been left on the runway after it had been closed for overnight maintenance work and that no runway inspection had been carried out once the work was complete. It was concluded that departing aircraft had probably become airborne before reaching the reported location and that ATC had reacted with insufficient urgency after beginning to receive FOD reports from previous landing aircraft once daylight prevailed.
