## Sequence of events

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

- Loss of control - on ground/water, landing - flare/touchdown
  - brakes(normal) - improper use of, dual student (cause)
  - supervision - inadequate, pilot in command(cfi) (cause)
  - directional control - not maintained, dual student (cause)
  - ground loop/swerve - uncontrolled, dual student (cause)

- In flight collision with terrain/water, landing - roll

## Analysis

THE STUDENT PILOT WAS BEING INSTRUCTED IN THE LANDING OF A TAIL DRAGGER AIRCRAFT, WHEN HE LOST CONTROL OF THE AIRCRAFT AT TOUCHDOWN. THE INSTRUCTOR FAILED TO TAKE CORRECTIVE ACTION WHEN THE STUDENT PILOT INADVERTENTLY APPLIED LEFT BRAKE, CAUSING THE AIRCRAFT TO GROUND LOOP TO THE LEFT AND SLIDE 200 FEET DOWN THE RUNWAY, DAMAGING THE MAIN GEAR AND FUSELAGE.

## 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 19860408011979A](https://openairdocs.org/incident/19860408011979A), Apr 8, 1986: Univac GC1B, Del Rio, TX, Substantial damage. Instructor failed to correct swerve and prevent a ground loop when the student misapplied the left brake.

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.
