Aircraft Accident/Incident Report
Phoenix, Arizona 85027
Thursday, January 21, 1999 16:38 MST
NTSB Narrative Summary Released at Completion of Accident
The certified flight instructor (CFI) reported that he decided to complete the instructional lesson with his 25-hour student pilot after flying in the local area and performing three touch-and-go landings. The CFI indicated that he observed a dust devil near the airport while on base leg, but its proximity to the airplane's planned course did not look close enough to result in his aborting the approach and landing. The CFI stated he believed that if he hurried up he could land before the dust devil became a factor. After landing without mishap, the crew turned off the runway and the dust devil contacted the airplane. Control was lost control and the airplane nosed over.
NTSB Probable Cause Narrative
The CFI's loss of airplane control upon encountering a dust devil due to his improper in-flight decision to land in proximity to the observed adverse weather conditions.
