Analysis

THE CERTIFIED FLIGHT INSTRUCTOR STATED THAT HIS INTENTIONS FOR THIS FLIGHT WERE TO SIMULATE AN ENGINE POWER LOSS DURING THE EARLY STAGES OF THE TAKEOFF ROLL AND HAVE THE STUDENT PERFORM A REJECTED TAKEOFF PROCEDURE. ACCORDING TO THE C.F.I., AT APPROXIMATELY 48 KNOTS HE REDUCED POWER ON THE LEFT ENGINE BY CUTTING OFF FUEL FLOW WITH THE MIXTURE CONTROL BUT THE STUDENT'S SLOW REACTION TO ABORT THE TAKEOFF, AND THE GUSTY CROSSWIND CONDITIONS CAUSED THE AIRCRAFT TO VEER OUT OF CONTROL, BEYOND CORRECTIVE ACTION. POST-ACCIDENT CALCULATIONS REVEAL THAT THE RUNWAY IN USE HAD A HEADWIND COMPONENT OF 17 KNOTS, A CROSSWIND COMPONENT OF 11 KNOTS, AND A DENSITY ALTITUDE OF 3,000 FEET ACTING ON NORMALLY ASPIRATED ENGINES.
