## Analysis

THE ACFT WAS BEING FLOWN ON A ROUTINE FLIGHT CHECK AFTER HAVING COMPLETED AN ANNUAL INSPECTION. THE PLT STATED THAT AFTER TAKEOFF HE CLIMBED TO 800 FT, TURNED DOWNWIND, EXTENDED FLAPS TO 30 DEG, SLOWED TO 70-80, & INTENDED TO MAKE A PASS OVER THE FIELD TO MAKE SURE IT WAS CLEAR PRIOR TO MAKING A FINAL APPROACH FOR LANDING. THE PLT THEN STATED THAT UPON ENTRY TO A RWY HEADING THE ACFT 'APPARENTLY ENTERED AN AREA OF EXTREME THERMO-LIFT CAUSING RIGHT WING TO RISE SUDDENLY CAUSING MOMENTARY INCREASE IN BANK AND APPARENT ACCELERATED STALL CAUSING AIRCRAFT TO DIVE INTO GROUND.' THE OFFICIAL TEMPERATURE RECORDED 0850 AT CHICAGO MIDWAY ARPT, LOCATED 18 MI NORTH, WAS 68 DEG F.

From the NTSB's public API. Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model.
