## Probable cause

PILOT'S FAILURE TO MAINTAIN ADEQUATE AIRCRAFT CONTROL DURING THE LANDING FLARE/TOUCHDOWN. THE TURBULENT WEATHER WAS A RELATED FACTOR.

## Sequence of events

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

- Hard landing, landing - flare/touchdown
  - weather condition - turbulence (contributing factor)
  - stall - inadvertent, pilot in command (cause)
- Nose gear collapsed, landing - flare/touchdown
  - landing gear,nose gear - overload

## Analysis

THE PILOT STATED THAT THE AIRPLANE BEGAN TO BUFFET AND STALLED WHILE ON SHORT FINAL. THE AIRPLANE IMPACTED THE RUNWAY NOSE FIRST AND THE NOSE GEAR COLLAPSED. THE AIRPLANE SWERVED OFF THE RUNWAY AND SKIDDED DOWN A WOODED EMBANKMENT LOCATED OFF THE LEFT SIDE OF THE AIRPORT. THE PILOT REPORTED THAT THE FLIGHT ENCOUNTERED MODERATE TURBULENCE DURING THE DESCENT, AND THERE WAS A RIGHT 10 KNOT CROSSWIND, WITH GUSTS TO 15 KNOTS.
