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

- Hard landing, landing - flare/touchdown
  - precautionary landing - performed, pilot in command
  - flare - premature, pilot in command (cause)
  - lack of familiarity with aircraft, pilot in command (contributing factor)

## Analysis

AFTER TAKEOFF ON THE THIRD FLIGHT OF THE NEW HOMEBUILT AIRCRAFT THE PILOT SMELLED 'SOMETHING HOT' AND NOTED A HIGH CYLINDER HEAD TEMP. DURING THE SUBSEQUENT PRECAUTIONARY LANDING THE PLT FLARED THE ACFT 3-4 FT ABOVE THE RWY RESULTING IN A HARD LANDING AND DAMAGE TO THE LEFT CANARD. NO MECHANICAL MALFUNCTIONS WERE REPORTED.
