## Probable cause

THE FAILURE OF THE PILOT TO MAINTAIN CONTROL OF THE AIRPLANE AND THE CFI'S INADEQUATE SUPERVISION OF THE PILOT.

## Sequence of events

In NTSB's coding before 2008 (https://www.ntsb.gov/GILS/Documents/codman.pdf).

- Dragged wing,rotor,pod,float or tail/skid, landing
  - aircraft handling - not maintained, dual student (cause)
  - supervision - inadequate, pilot in command(cfi) (cause)
  - touch-and-go - performed, pilot in command(cfi)

## Analysis

ON FOURTH POWER-OFF APPROACH TO TOUCH-AND-GO LANDING, THE PLT OVERSHOT THE CENTERLINE AND BANKED BACK STEEPLY, DRAGGING WINGTIP BEFORE TOUCHDOWN. THE CFI TOOK CONTROL AND EXECUTED A TAKEOFF AND FLEW AROUND THE PATTERN TO LAND AGAIN. IT WAS LATER DISCOVERED THAT THE LEFT WING WAS BENT.

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.
