- Hard landing, landing - flare/touchdown
  - airspeed - not maintained, pilot in command (cause)

## Analysis

THE PILOT REPORTED THAT WHILE ON FINAL APPROACH TO LAND, FULL FLAPS WERE EXTENDED AS THE AIRCRAFT CROSSED OVER A HILL IMMEDIATELY BEFORE THE RUNWAY THRESHOLD. AFTER FULL FLAPS WERE SELECTED, THE AIRCRAFT ENTERED A HIGH SINK RATE AND LANDED HARD ON THE END OF THE RUNWAY. NO FURTHER PROBLEMS WERE NOTED DURING THE LANDING AND ROLL-OUT. THE PILOT EXAMINED THE AIRCRAFT AND DID NOT OBSERVE ANY DAMAGE. AFTER THE AIRCRAFT WAS FLOWN BACK TO HOUSTON, TX, A MORE COMPLETE INSPECTION REVEALED THAT A WING SPAR ASSEMBLY WAS SUBSTANTIALLY DAMAGED.
