On 30 January 2013, the crew of a Boeing MD82 successfully rejected its take off at Copenhagen after sudden explosive failure of the left hand JT8D engine occurred during the final stage of setting take off thrust. Full directional control of the aircraft was retained and the failure was contained, but considerable engine debris was deposited on the runway. The subsequent Investigation concluded that a massive failure within the low pressure turbine had been initiated by the fatigue failure of one blade, the reason for which could not be established.
Description
On 30 January 2013, the crew of a Boeing MD82 (SE-DIK) being operated by SAS on a scheduled passenger flight from Copenhagen to Dublin rejected a daylight take off in normal ground visibility when a loud "bang" was heard and the aircraft began veering to the left and the take off was rejected. Since there appeared to be no smoke or fire, the runway was vacated to await confirmation of that from the Airport Fire Service, which was received. Passengers were disembarked to buses. Although there was no damage to the aircraft other than to the failed left engine, an inspection of the runway found a large quantity of engine debris.
Investigation
An Investigation was carried out by the Aviation Unit of the Danish Accident Investigation Board (AIB). It was immediately established that severe internal damage had resulted in the failure of the left hand Pratt and Whitney JT8D-217C engine. Recorded data was successfully downloaded from the removed DFDR and Cockpit Voice Recorder (CVR) and used to assist in the Investigation.
It was found that action to reject the take off had been initiated at 76 KIAS. It was determined at an early stage that the flight crew response had been appropriate and it therefore "decided not to investigate the operational aspect any further".
