THE PILOT'S FAILURE TO MAINTIAN PROPER AIRSPEED WHILE ON FINAL APPROACH.

## Sequence of events

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

- Loss of control - in flight, approach - vfr pattern - final approach
  - airspeed - not maintained, pilot in command (cause)
  - stall - inadvertent, pilot in command (cause)
- Hard landing, descent - uncontrolled
  - terrain condition - rough/uneven
  - terrain condition - ditch (contributing factor)

## Analysis

THE STUDENT PILOT OF THE CESSNA 182 WAS PRACTICING TOUCH-AND-GO LANDINGS AT HIS PRIVATE GRASS AIRSTRIP.  DURING THE THIRD APPROACH, WHICH WAS LOW, FLAT, AND SLOW, THE AIRCRAFT, WHICH WAS USING 40 DEGREES OF FLAPS, STALLED FROM AN ALTITUDE OF 30 TO 35 FEET.  A WITNESS STATED THAT THE AIRCRAFT HIT THE GROUND IN A 5 DEGREE RIGHT BANK AND SLID OVER A CONCRETE DITCH, COMING TO A STOP APPROXIMATELY 100 FEET ONTO THE RUNWAY.  A 10 KNOT DIRECT CROSSWIND WAS PRESENT DURING THIS SEQUENCE.
