Narrative:

On the takeoff roll as the power levers were advanced through 2000 pounds torque and as the airspeed was just coming alive (at about 40-50 KTS), the #1 engine flamed out. I immediately commenced the abort by retarding the power levers, and during this action the #2 engine flamed out as well. The abort process was continued normally, and the aircraft was secured. The captain made an announcement that no evacuate/evacuation was necessary. The aircraft was then towed to the gate with no further incident. The cause is yet unknown to the crew. All run-ups and checklists had checked good. Callback conversation with reporter revealed the following: the aircraft was a shorts 360, a high winged turbo propeller commuter. It had been sitting on the ramp for 3 days and had suffered exposure to the elements, snow and rain, for the 2 days prior but had been deiced that morning. The cause of the engine failures on takeoff was that amounts of ice and slush that was found in the engine's intake manifold. Evidently, the lower power during start and taxi did not affect the air requirements until the takeoff power was set. Several yrs ago this air carrier had experienced difficulties with foreign object damage, that of ingesting the engine air intake covers when they weren't removed prior to engine start. As a result, the air carrier started to keep them off at all times, until this event occurred. Now the air carrier is back to using the covers and will have to deal with the old problem of foreign object ingestion. The aircraft being a high wing kept the flight crew from accurately assessing the condition of the air intakes from the ground.

Title: SHORTS 360 ABORTS TKOF WHEN ENG FLAMES OUT. DURING ABORT, SECOND ENG FOLLOWS SUIT.

Narrative: ON THE TKOF ROLL AS THE PWR LEVERS WERE ADVANCED THROUGH 2000 LBS TORQUE AND AS THE AIRSPD WAS JUST COMING ALIVE (AT ABOUT 40-50 KTS), THE #1 ENG FLAMED OUT. I IMMEDIATELY COMMENCED THE ABORT BY RETARDING THE PWR LEVERS, AND DURING THIS ACTION THE #2 ENG FLAMED OUT AS WELL. THE ABORT PROCESS WAS CONTINUED NORMALLY, AND THE ACFT WAS SECURED. THE CAPT MADE AN ANNOUNCEMENT THAT NO EVAC WAS NECESSARY. THE ACFT WAS THEN TOWED TO THE GATE WITH NO FURTHER INCIDENT. THE CAUSE IS YET UNKNOWN TO THE CREW. ALL RUN-UPS AND CHKLISTS HAD CHKED GOOD. CALLBACK CONVERSATION WITH REPORTER REVEALED THE FOLLOWING: THE ACFT WAS A SHORTS 360, A HIGH WINGED TURBO PROP COMMUTER. IT HAD BEEN SITTING ON THE RAMP FOR 3 DAYS AND HAD SUFFERED EXPOSURE TO THE ELEMENTS, SNOW AND RAIN, FOR THE 2 DAYS PRIOR BUT HAD BEEN DEICED THAT MORNING. THE CAUSE OF THE ENG FAILURES ON TKOF WAS THAT AMOUNTS OF ICE AND SLUSH THAT WAS FOUND IN THE ENG'S INTAKE MANIFOLD. EVIDENTLY, THE LOWER PWR DURING START AND TAXI DID NOT AFFECT THE AIR REQUIREMENTS UNTIL THE TKOF PWR WAS SET. SEVERAL YRS AGO THIS ACR HAD EXPERIENCED DIFFICULTIES WITH FOREIGN OBJECT DAMAGE, THAT OF INGESTING THE ENG AIR INTAKE COVERS WHEN THEY WEREN'T REMOVED PRIOR TO ENG START. AS A RESULT, THE ACR STARTED TO KEEP THEM OFF AT ALL TIMES, UNTIL THIS EVENT OCCURRED. NOW THE ACR IS BACK TO USING THE COVERS AND WILL HAVE TO DEAL WITH THE OLD PROB OF FOREIGN OBJECT INGESTION. THE ACFT BEING A HIGH WING KEPT THE FLC FROM ACCURATELY ASSESSING THE CONDITION OF THE AIR INTAKES FROM THE GND.
