## Analysis

THE PLT ATTEMPTED A LANDING ON RWY 30 WHICH IS 85 FT HIGHER IN ELEV AT THE APPROACH END OF THE RWY THAN THE DEPARTURE END. THIS WAS THE PLT'S FIRST FLT TO THIS ARPT. THE ACFT TOUCHED DOWN FURTHER DOWN THE RWY THAN INTENDED SO THE PLT APPLIED PWR TO ABORT THE LANDING. THE PLT STATED THE WIND WAS GUSTY AND THAT A DOWNDRAFT WAS ENCOUNTERED DURING THE CLIMBOUT WHICH RESULTED IN THE ACFT CONTACTING TREES.
