What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) The pilot became distracted during preflight preparation and neglected to remove a tie-down strap and ratchet device from the wing. After take-off the pilot noticed the tie-down device trailing from below the wing and elected to return for a precautionary landing, concerned that damage to control surfaces might occur. As a result of the distraction the pilot did not extend the landing gear and landed with the gear up.
