What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Student pilot was practicing touch and go landings when he encountered a dust devil after the 4th landing and the acft flipped over on the rwy. Other circumstances are unknown. (.19) on January 21, 1999, at 1638 hours mountain standard time, a Cessna 152, N96640, operated by westwind aviation academy, nosed over while taxiing from landing on runway 25R at the Deer valley municipal airport, Phoenix, Arizona. Visual meteorological conditions prevailed at the time of the instructional flight, and no flight plan was filed. The airplane was substantially damaged. Neither the commercial certificated flight instructor nor the student pilot was injured. The flight originated from the Deer valley municipal airport about 1500. The flight instructor (CFI) reported that he decided to complete the instructional lesson after flying in the local area during which three touch-and-go landings were performed. The CFI was aware that the local wind was reported as 330 degrees, 35 knots with gusts to 50 knots. The CFI stated that he and his student observed a nearby dust devil as they taxied off the runway. The student said that the dust devil appeared to changed its direction of travel, and both he and the CFI were handling the flight controls. Suddenly, control of the airplane was lost and it nosed over. According to the local air traffic controller, at the time of the accident peak wind gusts were observed at 84 knots. (.4)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. (-23)instructor had just concluded the instructional flight due to increasing gusty winds. While waiting for taxi clearance after landing the aircraft was overtaken form the rear by a large dust devil and flipped upside down onto the taxiway. Existence of the dust devil was confirmed by dvt tower personel who observed the accident as it occurred. Both the student and the instructor reported that they had not encountered any difficulties up to the time that the aircraft was flipped over.
