Analysis

AFTER TAKING OFF IN MOUNTAINOUS TERRAIN, THE PILOT PREMATURELY TURNED ON COURSE TO A NORTHERLY HEADING, INTENDING TO CROSS OVER A RIDGE LINE. SHORTLY AFTER THE TURN, AND WHILE FLYING UP A DRAINAGE AREA TOWARDS RISING TERRAIN, HE ENCOUNTERED A DOWNDRAFT CONDITION WHICH REDUCED THE AIRCRAFT'S CLIMB PERFORMANCE. ITS CLIMB PERFORMANCE HAD ALREADY BEEN AGGRAVATED BY HIGHER THAN USUAL DENSITY ALTITUDE CONDITIONS. SUBSEQUENTLY, THE AIRCRAFT COLLIDED WITH TREES WHILE THE PILOT WAS ATTEMPTING TO REVERSE COURSE.
