## Probable cause

THE STUDENT PILOTS FAILURE TO MAINTAIN DIRECTIONAL CONTROL DURING A GO AROUND.  FACTORS RELATING TO THE ACCIDENT WERE THE SOFT RUNWAY CONDITIONS AND THE INADEQUACY OF TRAINING IN THE MANEUVER ATTEMPTED BY THE STUDENT.

## Sequence of events

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

- Loss of control - in flight, landing - flare/touchdown
  - directional control - not maintained, pilot in command (cause)
  - inadequate initial training, flight instructor(on ground) (contributing factor)
- Nose over, landing
  - terrain condition - soft (contributing factor)

## Analysis

THE STUDENT PILOT ON A CROSS COUNTRY FLIGHT WAS ATTEMPTING A LANDING ON A ROUGH FIELD. HE ATTEMPTED A GO AROUND AFTER THE NOSE WHEEL ENCOUNTERED THE SOFT SURFACE. FULL POWER WAS ADDED IN A NOSE HIGH ATTITUDE, RUDDER WAS INEFFECTIVE AND THE AIRPLANE DRIFTED LEFT ON TAKEOFF ROLL STRIKING A SNOW BERM AND NOSING OVER. THE STUDENT'S TRAINING WAS FOUND TO BE LACKING IN THE FOLLOWING SUBJECTS: PROPELLER GYRO, 'P' EFFECT AND LOSS OF RUDDER EFFECTIVENESS IN HIGH POWER, NOSE HIGH, LOW SPEED MANEUVERS.
