What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot stated he was operating off of memory and not following a check-list. Said he pulled the gear selector to unlock it and put the gear down, but did not visually verify that it was in the locked position or that he had three green gear indication lights. Stated he could not hear the aural warning due to his noise canceling headset. He saw the red gear unsafe light but extingushed it instinctively as it was habitual in this reduced power condition. Failed to notice unmutable gear warning when flaps configured at 10 degrees because his attention was overly devoted to instruction of the student. Performed a short final check without visually verifying conditions. Landed aircraft with gear in the up position. Aircraft landed on runway 19L with retracted gear.
