ISRAEL AIRCRAFT INDUSTRIES 1124A, TAOS, N.M., NOV. 8, 2002–The NTSB determined the probable cause of this accident was the pilot’s inadvertent flight into mountain-wave weather conditions while IMC, resulting in loss of aircraft control.

Examination of the airframe and engines did not disclose any structural or mechanical anomalies that would have prevented normal operation. The National Weather Service (NWS) had issued a sigmet for severe turbulence and mountain-wave activity. Satellite images depicted bands of altocumulus undulates and rotor clouds over the accident-site area.
