## Probable cause

THE PILOT'S PREMATURE FLARE.

## Sequence of events

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

- Hard landing, landing
  - throttle/power control - reduced, pilot in command
  - flare - premature, pilot in command (cause)
  - stall - inadvertent, pilot in command

## Analysis

THE PILOT APPROACHED WITH FULL FLAPS AND CUT THROTTLE BEFORE THE THRESHOLD.  WHEN HE FLARED, THE AIRPLANE STALLED 5 TO 10 FEET ABOVE THE RUNWAY AND LANDED HARD.
