Factual narrative
THE PLT STATED THAT HE ENCOUNTERED A WIND SHEAR ON FINAL. AT THE TIME OF THE ACCIDENT THE WIND WAS RECORDED TO BE FROM THE SOUTH/SOUTHEAST AT TWO KNOTS WITH PEAK WINDS AT FOUR KNOTS. WHEN THE PLT NOTICED THAT HIS AIRSPEED HAD DETERIORATED TO 50 MPH, HE WENT FROM 10 DEGREES OF FLAPS TO FULL FLAPS AND ALSO ADDED FULL POWER. THE ACFT STRUCK TWO TREES BEFORE IT DESCENDED TO THE GROUND IN A NOSE LOW ATTITUDE. THE ACFT HAS NO STALL WARNING INDICATOR.
