## Sequence of events

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

- Nose over, landing - roll
  - directional control - not maintained, dual student
  - remedial action - performed, pilot in command(cfi)
  - ice/frost removal from aircraft - excessive, dual student (cause)
  - lack of recent experience in type of aircraft, dual student
  - supervision - inadequate, pilot in command(cfi) (contributing factor)

## Analysis

DURING THE THIRD TOUCH & GO LANDING THE CERTIFICATED PLT RECEIVING DUAL INSTRUCTION WAS AT THE CONTROLS WHEN DIRECTIONAL CONTROL WAS TEMPORARILY LOST. THE CFI IN THE FRONT COCKPIT REGAINED CONTROL. SHORTLY THEREAFTER THE PLT UNDER INSTRUCTION APPLIED HEAVY BRAKING CAUSING THE ACFT TO NOSE OVER COMING TO REST INVERTED.
