Investigator assessment
Analysis narrative
Just before touching down to land, the pilot could not remember if he extended the landing gear. He said he then grabbed the gear handle (which was in the down position) and retracted the gear. The glider landed gear up and bounced, which resulted in substantial damage to the fuselage, tail boom, and tail section.
