Burkhart Grob G102 Std Astir IIIS/N: 55565

Summary

On June 16, 2007, a Burkhart Grob G102 Std Astir III (N123KG) was involved in an incident near Wickenburg, AZ. All 1 person aboard were uninjured. The aircraft sustained substantial damage.

The National Transportation Safety Board determined the probable cause of this incident to be: The pilot's inadequate compensation for wind conditions which resulted in an inflight collision with a cactus tree while landing. The loss of thermal lift, tailwind, gusts, and tree were contributing factors to the accident.

The glider pilot was conducting a cross-country flight. Approximately 4 hours into the flight, the pilot experienced a loss of thermal lift. He reversed course and attempted to land on an uncharted airstrip. During the forced landing, wind gusts and a tailwind were present. On final approach, "a strong gust/windshear" moved the glider to the right side of the runway. The right wing impacted a cactus tree and sustained substantial damage. The pilot said that there were no mechanical malfunctions.

This incident is documented in NTSB report SEA07CA175. AviatorDB cross-references NTSB investigation data with FAA registry records to provide comprehensive safety information for aircraft N123KG.
