Narrative:

Upon departure from the airport I was repositioning my kneeboard from the door pocket to my knee. As I brought the kneeboard up and away from the door pocket it passed within a few inches of the open pilot door window. It was immediately sucked from my grasp and departed the aircraft. A person in the cabin witnessed the kneeboard strike the port side sponson and then [it] continued down and away from the ship. The sponson received minor damage. We normally fly with the rear doors closed on this ship. However; due to the extreme heat; we chose to fly with the doors open this day. In this configuration; there is a significant flow of air forward which contributed to the negative pressure in the cockpit.
