Analysis

Witnesses observed black smoke trailing from the homebuilt acft during takeoff & initial climb. The acft was observed to climb to an estimated alt of 150 to 200 ft where eng sound ceased & the prop stopped. The acft was then observed to attempt a left turn back toward the rwy. During the turn, the nose came up & witnesses stated that the acft stalled about one-half way through the turn & crashed to the ground. An exam of the cockpit revealed that the hand actuated fuel primer was in the unlocked & out position. A review of the acft's checklists failed to reveal any reference to ensuring that the primer is in & locked after engine start.
