Summary:

The aircraft was on its takeoff run for a test flight after annual maintenance. At approximately 80 kt IAS the pilot became aware of a severe lateral vibration which was followed by failure of the nose landing gear (NLG). The aircraft came to stop on the runway in a nose-down attitude, resting on the remains of the nose gear strut. The failure was caused by the propagation of a crack in the NLG forging, emanating from a bolt hole in the anti-shimmy damper bracket.
