(Pilot) Heard A Loud “Bang” As The Nose Gear Collapsed And The Nose Continued To Settle, Sliding Down The Runway Surface Analysis: The pilot stated that when he touched down, the main landing gear contacted the runway surface, followed by the nose gear. He instantly heard a loud “bang” as the nose gear collapsed and the nose continued to settle, sliding down the runway surface. Examination of the nose gear revealed that the nose landing gear actuator failed due to the buckling and fracture of the ball screw, which resulted from compressive loads on the actuator assembly.
