HISTORY OF THE FLIGHT
The aircraft took-off at 1806hrs. Following an uneventful flight, the crew reported that the aircraft arrived overhead DNPO at about 1843hrs and was vectored by Air Traffic Control (ATC) to descend to 3500ft and on a heading to cross extended centre line of ILS runway 21. Having crossed the extended centre line, the crew assessed and discussed the approach: the weather as depicted on the weather radar, and noted that there were no clouds from 7nm to the threshold. The aircraft was cleared for a localizer approach runway 21 and to descend initially to 2400ft. The PF executed a left turn and a gradual descent, intercepting the localizer at 17nm on the POT VOR/DME while descending to 2400ft on QNH 1008. Localizer was captured while in the descent on Auto Pilot 2 (AP2). The Minimum Descent Altitude (MDA) was adjusted to 460ft for Glide Slope out approach. The crew observed there was weather between 17nm and 7nm on the VOR/DME, but the ride on the approach was comfortable. At this time, the aircraft was in a landing configuration, flaps 40.
The crew reported that the runway had experienced recent rain before arrival and after touch down, looked and felt contaminated with flood of water that did not drain well.
After the aircraft came to a complete stop, engines were shut down and emergency power switch was turned ON. Emergency light came ON, all other lights were OFF and the Public Address System was not working, the Lead crew had to open the cockpit door to obtain emergency evacuation instructions from the Captain. Emergency evacuation was carried out using only the left forward main door and the escape slide on this door did not deploy.
The Airport Rescue and Fire Fighting Services (ARFFS) arrived during the evacuation. All persons on board were evacuated unhurt.
The accident occurred at night.
