Shortly after full power was applied for takeoff, the pilot noticed that the aircraft was tracking to the left of the strip centre. He turned gently right to correct the situation and the nosegear leg collapsed soon after. Metallurgical examination concluded that the nosegear leg mounting trunnions contained fatigue cracks. One trunnion had failed during this takeoff. The aircraft had accrued almost 20,000 hours and an inspection recommended by the aircraft manufacturer less than one year prior to the accident had not been conducted. Had the inspection been conducted, the fatigue cracks should have been detected. Some time after this aircraft was manufactured the manufacturer altered the design of the mounting trunnions to make them stronger.
