Narrative:

Flight was descending towards cairo from FL330 to FL120. At approximately FL180 what I considered to be light rain commenced, but rapidly developed into a brownish color and the noise intensity increased to a sound level which could have been mistaken for extremely heavy hail. This could only have been sand. The captain and first officer's windshield received substantial damage, and #2 engine failed, despite continuous ignition, engine anti-ice and flight start being selected. During this phase the 'whoop-whoop' 'pull up' sounded several times. I called out, 'engine failure #2 engine', and automatically backed up hydraulics. The engine failure checklist was successfully complete, and the amplification portion of this emergency drill in section 3 consulted. The emergency required the completion of the loss of generator and the loss of 1 bleed source drills, which were accomplished in a similar fashion. The APU was also successfully started. Subsequently #1 engine duct overheat drill required to be actioned. This drill was completed, and the loss of 2 bleed sources actioned. However, this bleed source was recovered and the drill discontinued. A successfully automatic landing was flown to cairo airport. Throughout the emergency captain behaved in an exemplary manner, directing his crew to the best possible advantage. Callback conversation with reporter revealed the following information: reporter unaware of maintenance required after landing but flight crew took the same airplane out the next day on another flight. First entry into cairo for all 3 flight crew members. None had ever encountered a sand storm aloft before this.

Narrative: FLT WAS DSNDING TOWARDS CAIRO FROM FL330 TO FL120. AT APPROX FL180 WHAT I CONSIDERED TO BE LIGHT RAIN COMMENCED, BUT RAPIDLY DEVELOPED INTO A BROWNISH COLOR AND THE NOISE INTENSITY INCREASED TO A SOUND LEVEL WHICH COULD HAVE BEEN MISTAKEN FOR EXTREMELY HVY HAIL. THIS COULD ONLY HAVE BEEN SAND. THE CAPT AND FO'S WINDSHIELD RECEIVED SUBSTANTIAL DAMAGE, AND #2 ENG FAILED, DESPITE CONTINUOUS IGNITION, ENG ANTI-ICE AND FLT START BEING SELECTED. DURING THIS PHASE THE 'WHOOP-WHOOP' 'PULL UP' SOUNDED SEVERAL TIMES. I CALLED OUT, 'ENG FAILURE #2 ENG', AND AUTOMATICALLY BACKED UP HYDS. THE ENG FAILURE CHKLIST WAS SUCCESSFULLY COMPLETE, AND THE AMPLIFICATION PORTION OF THIS EMER DRILL IN SECTION 3 CONSULTED. THE EMER REQUIRED THE COMPLETION OF THE LOSS OF GENERATOR AND THE LOSS OF 1 BLEED SOURCE DRILLS, WHICH WERE ACCOMPLISHED IN A SIMILAR FASHION. THE APU WAS ALSO SUCCESSFULLY STARTED. SUBSEQUENTLY #1 ENG DUCT OVERHEAT DRILL REQUIRED TO BE ACTIONED. THIS DRILL WAS COMPLETED, AND THE LOSS OF 2 BLEED SOURCES ACTIONED. HOWEVER, THIS BLEED SOURCE WAS RECOVERED AND THE DRILL DISCONTINUED. A SUCCESSFULLY AUTO LNDG WAS FLOWN TO CAIRO ARPT. THROUGHOUT THE EMER CAPT BEHAVED IN AN EXEMPLARY MANNER, DIRECTING HIS CREW TO THE BEST POSSIBLE ADVANTAGE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR UNAWARE OF MAINT REQUIRED AFTER LNDG BUT FLC TOOK THE SAME AIRPLANE OUT THE NEXT DAY ON ANOTHER FLT. FIRST ENTRY INTO CAIRO FOR ALL 3 FLC MEMBERS. NONE HAD EVER ENCOUNTERED A SAND STORM ALOFT BEFORE THIS.
