The NTSB's narrative final · quoted from the NTSB record

DURING A DUAL CROSS COUNTRY FLIGHT THE FLIGHT INSTRUCTOR (CFI) FLEW INTO AN AREA OF RISING MOUNTAINOUS TERRAIN. THE CFI PLANNED TO INSTRUCT HIS STUDENT IN MOUNTAIN FLYING TECHNIQUES. THE AIRPLANE ENCOUNTERED AN UPDRAFT AND THEN A DOWNDRAFT. THE CFI LOWERED THE WING FLAPS TO THE 10 DEGREE POSITION IN A BELIEF THAT SUCH ACTION WOULD ENHANCE THE AIRPLANE'S RATE OF CLIMB. THE AIRPLANE'S CLIMB PERFORMANCE WAS NOT ENHANCED AND REMAINED INADEQUATE TO OUT CLIMB THE RISING TERRAIN. THE AIRPLANE COLLIDED WITH A TREE AND THE SIDE OF A HILL.
