The NTSB's narrative final · quoted from the NTSB record
THE PURPOSE OF THE DUAL INSTRUCTIONAL FLIGHT WAS FOR THE INSTRUCTOR PILOT TO CHECK OUT A PRIVATE PILOT IN THE CONVENTIONAL GEAR CESSNA 140 AIRCRAFT. AFTER A SERIES OF UNEVENTFUL FULL STOP & TOUCH & GO LANDINGS, THE STUDENT WAS DIRECTED TO LAND. THE CFI & A GROUND BASED WITNESS REPORTED THAT THE ACFT LANDED NORMALLY. THE WITNESS REPORTED THAT DURING THE LAST PORTION OF THE ACFT'S ROLL OUT THE SURFACE WIND PROVIDED THE ACFT WITH A TAILWIND COMPONENT. THE CFI REPORTED THAT HER STUDENT 'CAME UP ON THE BRAKES' & SHE DIRECTED HIM NOT TO BRAKE. THE CFI FURTHER STATED THAT DESPITE HER EFFORT AT SAVING THE ACFT BY APPLYING BACK PRESSURE TO THE YOKE, SHE LOST CONTROL & THE ACFT NOSED OVER.
