Quote: FROM: AIRBUS FLIGHT SAFETY DEPARTMENT (AFSD) TOULOSE TO: ALL AIRBUS OPERATORS/ ATTN: FLIGHT SAFETY SUBJECT: Sudan Airways SD109 accident in Khartoum, Sudan This AIT is an update of SD109 AIT N 1 regarding the A310 accident during landing on runway 36 at Khartoum, Sudan, which occurred on the 10th of June 2008 at 20:26 local time. The data which follows has been approved for release by the commission of investigation led by the Sudan Investigation Authorities (SIA). The DFDR and CVR have been read-out at the French (Bureau Enquete et Analyse-BEA) in Paris under the leadership of the In-Charge Investigation Authorities from Sudan in the 9th of July 2008. The preliminary review of available data indicates that the following sequence of events: v The aircraft was dispatched with thrust reverser (THR REV) of Engine (1)(LH) deactivated. v The landing was performed in rainy conditions, runway was wet, latest wind data communicated to the crew was: 320 degrees / 07 Kt. v The Captain was PILOT FLYING (PF). v The approach was nominal with the aircraft being configured for landing with SLATS & FLAPS fully extended and GROUND SPOILERS armed. The AUTO PILOT was disconnected at 800ft. v RADIO-ALTITUDE and the AUTO-THROTTLE were kept engaged till landing. v Bothe Thrust Levers (THR LVRs) were set to IDLE detent for touchdown (T/D). v The touchdown (T/D) occurred at a 134Kt indicated air speed (IAS) and a 155Kt ground speed (GS) v Initial assessment indicates that the touchdown was smooth and occurred about 900 meters beyond the runway “R/W) threshold (Landing Distance Available (LDA) for runway 36 is 2980 meters”. v The ground spoilers (GRD SPLR) normally deployed, except SPOILER #5 which were FAULTY. v Upon crew selection of both thrust reversers to MAX REV, the engine 2 reverser deployed normally, while engine 1 thrust reverser normally stowed since it was inhibited prior aircraft dispatch. v About 10 seconds after T/D. at 98kt IAS and a 122kts GS, both reversers were deselected and the operative reverser stowed. Both thrust reversers were then kept to IDLE detent. v About 20 seconds after T/D, at 90kt IAS and a 107kt GS, the GPWS warnings; TERRAIN~ TERRAIN, followed by continuous PULL UP~PULL UP were triggered. The cause of these spurious warnings has not been determined yet. v About 28 seconds after T/D, at 90kt IAS and a 93kt GS, the crew selected again both thrust reversers to MAX REV, this was about 7 seconds prior to aircraft overrun the runway at 76kt Ground Speed. v The rollout phase lasted for about 36 seconds. Crew reportedly set the BRK A/SKID switch to ALTN OFF during the rollout. This is consistent with the observed position of the switch during wreckage investigation. v The aircraft came to a rest at about 200m after the runway end. v On-site investigation has shown that the fire started as the aircraft had stopped. v The investigation will now focus at determining the reasons for the followings I. The low deceleration. II. The GPWS spurious warnings. III. The fire ignition. v At this stage of the investigation, Airbus has got no specific recommendation to be raised to the operators. ; --------------------------------- CAPT./ SIDDIG ABUFAWAZ
