## Probable cause

THE CFI PILOT-IN-COMMAND'S FAILURE TO PROVIDE ADEQUATE SUPERVISION OF A DUAL STUDENT. A FACTOR CONTRIBUTING TO THE ACCIDENT WAS THE STUDENT PILOT'S FAILURE TO MAINTAIN AIRSPEED.

## Sequence of events

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

- Hard landing, landing - flare/touchdown
  - light condition - dark night
  - airspeed - not maintained, dual student (contributing factor)
  - stall - inadvertent, dual student
  - supervision - inadequate, pilot in command(cfi) (cause)
- Main gear collapsed, landing - flare/touchdown
  - landing gear,main gear attachment - overload

## Analysis

A PRIVATE RATED DUAL STUDENT WAS RECEIVING NIGHT INSTRUCTION.  DURING A SIMULATED FORCED LANDING THE AIRPLANE LANDED HARD AND THE RIGHT MAIN LANDING GEAR COLLAPSED.  THE AIRPLANE SLID TO A STOP IN A TREE LINE.  THE INSTRUCTOR STATED, '... STALLED THE AIRPLANE ABOUT 10 FEET OR SO CAUSING THE AIRPLANE TO HIT HARD ON THE RIGHT MAIN, BREAKING IT OFF.'
