## Probable cause

THE PILOT AT THE CONTROLS FAILED TO MAINTAIN DIRECTIONAL CONTROL OF THE AIRPLANE, AND THE FLIGHT INSTRUCTOR PROVIDED INADEQUATE SUPERVISION.  A RELATED FACTOR WAS THE PILOT AT THE CONTROLS HAD NO FLIGHT EXPERIENCE IN THE MAKE AND MODEL OF AIRPLANE BEING FLOWN.

## Sequence of events

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

- Loss of control - on ground/water, takeoff - roll/run
  - light condition - dusk
  - directional control - not maintained, copilot/second pilot (cause)
  - lack of total experience in type of aircraft, copilot/second pilot (contributing factor)
  - supervision - inadequate, pilot in command(cfi) (cause)
- On ground/water encounter with terrain/water, takeoff - roll/run
  - terrain condition - snowbank
- Nose over, takeoff

## Analysis

A FLIGHT INSTRUCTOR OFFERED TO GIVE INSTRUCTION, IN A TAILWHEEL AIRPLANE, TO A RATED COMMERCIAL PILOT WHO HAD NOT FLOWN IN THIS MAKE AND MODEL PRIOR TO THIS FLIGHT.  THE RATED PILOT RECEIVING INSTRUCTION WAS SEATED IN THE LEFT SEAT OF THE AIRPLANE.  THE AIRPLANE WAS NOT EQUIPPED WITH BRAKES ON THE RIGHT SIDE WHERE THE FLIGHT INSTRUCTOR WAS SEATED. POWER WAS APPLIED AND THE AIRPLANE ACCELERATED.  THE RATED PILOT ON THE CONTROLS DID NOT MAINTAIN DIRECTIONAL CONTROL AND THE AIRPLANE VEERED TO THE LEFT.  THE FLIGHT INSTRUCTOR WAS UNABLE TO CORRECT THE LEFT VEER WITH RUDDER.  THE AIRPLANE LEFT THE RUNWAY, WAS CAUGHT IN A SNOW BANK AND NOSED OVER.

## Other investigations on N8775K (1)

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.
