## Sequence of events

- Overrun, landing - roll
  - wind information - not obtained, pilot in command(cfi) (contributing factor)
  - weather condition - tailwind (contributing factor)
  - wrong runway - selected, pilot in command(cfi) (contributing factor)
  - airspeed - misjudged, dual student (contributing factor)
  - distance - misjudged, dual student (contributing factor)
  - go-around - not performed, pilot in command(cfi) (cause)
  - crew/group coordination - inadequate, pilot in command(cfi) (cause)
  - relinquishing of control - delayed, dual student (contributing factor)
  - directional control - not maintained, pilot in command(cfi) (cause)
  - ground loop/swerve - uncontrolled
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - dirt bank/rising embankment
- Gear collapsed, landing
  - landing gear - overload

## Analysis

UPON ARRIVAL AT THE UNCONTROLLED ARPT, NEITHER THE INSTRUCTOR (CFI) NOR THE STUDENT OBSERVED THE ARPT'S WIND SOCK. THE ACFT WAS OBSERVED TO TOUCH DOWN MIDWAY DOWN THE RWY & BOUNCE ONCE DURING THE LANDING. AS THE ACFT NEARED THE END OF THE RWY, THE CFI REALIZED THAT THERE WAS INSUFFICIENT REMAINING RWY TO STOP, SO SHE TOOK OVER THE CONTROLS. THE STUDENT STATED THAT THE CFI DID NOT INSTRUCT HIM TO RELINQUISH CONTROL, & THE CFI STATED SHE DID NOT DIRECT HER STUDENT TO RELEASE ALL THE CONTROLS. THE ACFT VEERED OFF THE RWY & SUBSEQUENTLY IMPACTED A 3-FT HIGH EMBANKMENT.

## FAA reports on this event (1)

The FAA's own accident and incident reports, matched to the aircraft by N-number and date (OpenAirDocs).

- [Accident 19840224005399A](https://openairdocs.org/incident/19840224005399A), Feb 24, 1984: Gulstm 112A, Yucca Valley, CA, Substantial damage. Instructor and student pilot lost directional control during downwind landing. Aircraft hit dirt embankment.

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.
