What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Mr. Sarasy was setting up on a 45 approach to runway 13 at the Novato airport (dvo). On his approach he heard on the radio that runway 13 was in use. He changed his approach to runway 31. As he did, he again went through his approach check list. At the point where the check list instructs him to extend the gear, he instead retracted the gear. He stated that he had already extended the gear earlier on the approach to the other runway. At touch down he noticed that the gear was not extended. The aircraft touched down and skidded to the left of the runway. It struck a taxi indicator light and came to rest about mid-field.
