Analysis

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.
