Aircraft Accident/Incident Report

NTSB Narrative Summary Released at Completion of Accident
According to the pilot, during the takeoff roll at about rotation speed, he felt the nose landing gear of the airplane "give way" and the airplane began to drift to the left. As he applied right rudder to correct the yaw, he felt "a continued collapse" of the nose landing gear and elected to abort the takeoff. The airplane's nose and both propellers struck the ground. Examination of photos provided by an insurance adjustor revealed that both engines were displaced down and to the right. The right engine firewall was torn from the engine nacelle, and the left engine firewall was buckled and distorted. Additionally, the photos revealed that the nose landing gear fork had broken into two pieces, which allowed the nose wheel to separate from the airplane, resulting in collapse of the nose landing gear. The pilot reported that "an aircraft structural engineer made the observation that my nose gear fork had an old hidden crack that could have contributed to the failure."
NTSB Probable Cause Narrative
the pre-existing crack in the nose wheel fork, which allowed separation of the nose wheel during the takeoff roll, resulting in collapse of the nose landing gear.
