## Sequence of events

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

- Undershoot, approach - vfr pattern - final approach
  - planned approach - inadequate, pilot in command (cause)
  - lowering of flaps - excessive, pilot in command (contributing factor)
  - flare - misjudged, pilot in command (cause)
- Complete gear collapsed, landing - flare/touchdown
  - landing gear - overload

## Analysis

WHILE ON FINAL APPROACH THE ACFT BEGAN TO FALL BELOW THE FLIGHT PATH THE PLT DESIRED. REMEDIAL ACTIONS WERE INSUFFICIENT TO CORRECT THE DEVIATION. THE ACFT IMPACTED SHORT OF THE RWY AND COLLAPSED THE LANDING GEAR. INVESTIGATION REVEALED THE USE OF 40 DEGREES OF FLAPS INSTEAD OF THE 30 DEGREES USED DURING THE PLT'S TRAINING. THE ACFT WAS OUTFITTED WITH A SET OF CONTROLS THAT ALLOWED THE PLT TO OPERATE THE RUDDER PEDALS BY HAND. THE PLT WAS A PARAPLEGIC AND HAD A REDUCED HEARING ABILITY WHICH SEVERELY RESTRICTED HIS VERBAL COMMUNICATION.
