What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Narrative: the pilot stated he was reviewing normal/abnormal emergency procedures for the airplane. He was doing this by sitting in the airplane and going through various checklists. This included moving some of the controls/switches. The landing gear lever was moved during this review. After the review, the airplane owner/pilot intended to make a local solo practice flight. During the takeoff roll, the nose of the airplane started to drop. The pilot said he pulled back on the control wheel, the airplane lifted off, and the gear retracted. He discovered he had inadvertently left the landing gear lever in the retract position after his previous review. He immediately returned for landing. Damage was limited to both propellers when the tips struck the runway. This incident is closed with this report.
