The pilot of an Extra Flugzeugbau GMBH EA 300/L stated that while on approach to final, and as he prepared to touchdown, he saw a sailboat, which did not have its sail raised. Consequently, he did not see the sail mast. The right wing tip struck the mast and shattered. The pilot added power in an attempt to level out the airplane, but it collided with the ground. The pilot said that he did not observe any abnormalities with the airplane or the engine during his approach. Examination by a Federal Aviation Administration (FAA) inspector revealed that the airplane’s right wing struck the sailboat approximately 8 feet below the top of the sail mast. Witnesses to the accident reported that the sailboat was operating approximately 50 yards from the seawall when the accident occurred. They said that the airplane attempted to curve around the sailboat but as the right wing dipped it hit the mast.
