## Probable cause

THE PILOT IN COMMAND TO PROPERLY JUDGE THE TIMING OF THE LANDING FLARE.

## Sequence of events

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

- Hard landing, landing - flare/touchdown
  - flare - improper, pilot in command (cause)
- Loss of control - on ground/water, landing - roll
  - directional control - not maintained, pilot in command (cause)
  - ground loop/swerve - inadvertent, pilot in command (cause)
- On ground/water encounter with terrain/water, landing - roll
  - terrain condition - rough/uneven

## Analysis

ON TOUCHDOWN, THE AIRCRAFT LANDED ON THE NOSE GEAR. THE PILOT LOST CONTROL OF THE AIRCRAFT AND IT RAN OFF THE RIGHT SIDE OF THE RUNWAY COLLIDING WITH SOME ROUGH DIRT AREAS. THE STUDENT PILOT SAID THAT HE ENCOUNTERED EITHER A WIND SHEAR OR A STRONG CROSS WIND JUST BEFORE TOUCHDOWN. NO PILOT REPORTS OF WINDSHEAR ACTIVITY WERE REPORTED EITHER BEFORE OR AFTER THE ACCIDENT. THE COMPUTED DIRECT CROSS WIND COMPONENT EXISTING AT THE TIME WAS 10 KNOTS LESS THAN THE MAXIMUM FACTORY DEMONSTRATED CROSS WIND COMPONENT OF THE CESSNA 182L.
