Narrative:

Multiple takeoffs and lndgs caused deterioration of mental awareness. Better judgement or education on physical/mental depletion could have prevented the gear up landing. Multiple practice lndgs caused me to become tired to the point that a change in traffic pattern direction distracted me enough to forget to put down the landing gear. Aircraft touched down smoothly and safety gear up. Damage was minimal, no injury.

Title: SMA PRACTICING CIRCUITS LANDS GEAR UP.

Narrative: MULTIPLE TKOFS AND LNDGS CAUSED DETERIORATION OF MENTAL AWARENESS. BETTER JUDGEMENT OR EDUCATION ON PHYSICAL/MENTAL DEPLETION COULD HAVE PREVENTED THE GEAR UP LNDG. MULTIPLE PRACTICE LNDGS CAUSED ME TO BECOME TIRED TO THE POINT THAT A CHANGE IN TFC PATTERN DIRECTION DISTRACTED ME ENOUGH TO FORGET TO PUT DOWN THE LNDG GEAR. ACFT TOUCHED DOWN SMOOTHLY AND SAFETY GEAR UP. DAMAGE WAS MINIMAL, NO INJURY.
