What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The pilot was cleared to land on runway 29L at kfat after a VFR flight from ksbp. He was able to see runway 29R, the larger runway, and had difficulty finding 29L visually. He did not ask ATC for assistance. He stated to the investigator that during the process of lining up with 29L, he "forgot" to lower the gear. He and his passenger were wearing noise cancelling headsets. The pilot did not hear the warning horn. It is unknown if this system was functional at the time of the incident. The aircraft landed on 29L with the gear in the retracted position. A current pilot operating handbook and aircraft checklist was observed in the aircraft but the pilot reported he did not follow a before landing checklist. The landing gear handle was observed in the up position during post incident investigation. The air traffic controller on duty reported that he recalled looking at the aircraft prior to landing and did not observe anything abnormal. He did not get a close enough view to determine the position of the gear. As the aircraft flew over the approach end of the runway, the controller stated he was scanning down field for surface traffic and did not observe the aircraft configuration.
