On June 5, 1991, a Cessna R182 (registration N484ER) operated by Embry-riddle Aero University was involved in an aviation accident near Williams, AZ. Investigators recorded the probable cause as: THAT THE FLIGHT ENCOUNTERED WINDSHEAR AND THAT AIRCRAFT CONTROL WAS NOT POSSIBLE. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
During a CFI instructional flight, a go-around after a bounced landing led to a wind shear encounter. The airplane yawed violently, settled, and cartwheeled upon landing.
Flight Details
The flight was conducted as a CFI instructional flight. The CFI/PIC occupied the left front seat, while a certificated commercial pilot undergoing CFI training occupied the right front seat and was flying the airplane. The CFI trainee had previously completed a touch-and-go landing and takeoff.
Sequence of Events
On the second landing, the airplane bounced. The CFI/PIC instructed the trainee to go around. The airplane lifted off and was climbing at best rate when it encountered a wind shear. The airplane yawed violently to the right. The CFI/PIC immediately assumed control of the flight controls but could only maintain a wings-level attitude. The airplane continued to settle and landed hard, then cartwheeled.
Environmental Conditions
The airport manager confirmed that virga and a dust devil appeared to engulf the airport without any warning.
