## Probable cause

THE FLIGHT INSTRUCTOR'S INADEQUATE SUPERVISION OF THE FLIGHT AND THE PRIVATE PILOT'S FAILURE TO MAINTAIN AIRSPEED. CONTRIBUTING TO THIS ACCIDENT WAS THE FAILURE OF THE MAIN LANDING GEAR DUE TO OVERLOAD.

## Sequence of events

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

- Hard landing, landing - flare/touchdown
  - supervision - inadequate, pilot in command(cfi) (cause)
  - airspeed - not maintained, dual student (cause)
- Gear collapsed, landing - roll
  - landing gear,main gear - overload (contributing factor)
  - landing gear,nose gear - overload (contributing factor)

## Analysis

THE CERTIFICATED PRIVATE PILOT WAS RECEIVING AN AIRPLANE MAKE AND MODEL COMPANY CHECK-OUT FROM A CERTIFIED FLIGHT INSTRUCTOR (CFI).  WHILE EXECUTING A NO FLAP APPROACH THE CFI FAILED TO ADEQUATELY SUPERVISE THE FLIGHT BY FAILING TO MONITOR THE AIRSPEED.  THE PRIVATE PILOT FAILED TO MAINTAIN THE AIRSPEED TO THE POINT THAT THE AIRPLANE STALLED AND LANDED HARD.  AFTER LANDING THE AIRPLANE PIVOTED TO THE LEFT AND CONTINUED DOWN THE RUNWAY UNTIL THE MAIN AND NOSE LANDING GEARS COLLAPSED FROM OVERLOAD.
