What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The flight instructor and the student (who was a private pilot), were practicing short field landings. The flight instructor stated that he was concentrating on the altitude and did not hear the gear unsafe horn. The student was not sure if he heard the gear unsafe horn or a stall warning horn short final. The aircraft landed with the gear up on the runway. The aircraft had damage to the prop and gear. The aircraft had some skin damage from the aircraft sliding on the runway. The aircraft's flaps were down which reduced the damage to the bottom of the aircraft. The mechanic is looking over the aircraft and will advise if he finds any additional damage.
