AT76, Surabaya Indonesia, 2014

Summary

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.

Description

On 11 June 2014, an ATR 72-600 (PK-WGK) being operated by Wings Air on a scheduled domestic passenger flight from Lombok to Surabaya as IW1861 was unable to avoid hitting FOD on the centreline of the landing runway at Surabaya in normal day visibility and sustained significant lower fuselage damage. There were no injuries to the occupants but eight substantial puncture holes were subsequently found in the lower aircraft fuselage, all attributed to running over a 4.5kg chisel. Two other items of FOD, a coil of compressor hose and a pneumatic drill (jackhammer) were subsequently recovered from the same part of the runway.

Investigation

An Investigation was carried out by the Indonesian National Transportation Safety Committee (NTSC) - the Komite Nasional Keselamatan Transportasi (KNKT). CVR and FDR data from the damaged aircraft were both downloaded but it was subsequently concluded that the latter would not be relevant. ATC TWR recordings were also obtained.
