## Probable cause

THE INSTRUCTOR PILOT (CFI) INADVERTENTLY ACTUATED THE LANDING GEAR HANDLE TO THE UP POSITION.

## Sequence of events

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

- Gear collapsed, landing - roll
  - gear retraction - inadvertent, pilot in command(cfi) (cause)

## Analysis

DURING THE THIRD TOUCH AND GO LANDING OF THE TRAINING FLIGHT, THE INSTRUCTOR MOMENTARILY PLACED THE LANDING GEAR HANDLE TO THE UP POSITION WHILE THE AIRPLANE WAS ON THE RUNWAY. THE LEFT MAIN GEAR RETRACTED FOLLOWED BY THE RIGHT. THE AIRPLANE DEPARTED THE RUNWAY TO THE LEFT SIDE AND CAME TO A STOP IN THE GRASS. THE PROCEDURES IN EFFECT AT THE TIME WERE FOR THE INSTRUCTOR TO SET THE FLAPS FOR TAKEOFF AFTER THE STUDENT HAD TOUCHED DOWN.
