NTSB Probable Cause

FAILURE OF THE PILOT-IN-COMMAND TO FOLLOW IFR PROCEDURES (MAINTAIN AN ILS GLIDE PATH OR INITIATE A MISSED APPROACH) DURING AN IFR ARRIVAL TO THE AIRPORT. FACTORS RELATED TO THE ACCIDENT WERE: UNFAVORABLE WEATHER CONDITIONS, AN ERRONEOUS WIND INDICATION FROM THE LOW LEVEL WINDSHEAR ALERT SYSTEM (LLWAS), WHICH RESULTED IN AN INACCURATE WEATHER (WIND) OBSERVATION, AND FAILURE OF THE PILOTS TO TAKE ADEQUATE REMEDIAL ACTION.
