Summary

Summary

The pilot was conducting spreading operations. On the 51st takeoff for the day, at a speed of about 35 knots and about 100 metres from the commencement of the take off run, the aircraft started to swing to the right. The pilot realised that he had no control over the swing so he closed the throttle and applied maximum braking. The aircraft continued to swing to the right, left the confines of the strip, and collided with a cattle yard. Examination of the aircraft showed that the right main gear oleo rod end fitting had failed. This had allowed the oleo to swing under the stubwing, jamming the wheel, resulting in loss of directional control. Inspection also revealed that the left landing gear rod end fitting was cracked. Both fittings were then subjected to metallurgical examination. This determined that the rod ends were of inferior quality with a hardness and tensile strength approximately 60 of other rod ends previously examined. This would indicate that the rod ends were not of aircraft standard. The source of supply of these components was not determined. This accident was not the subject of an on-scene investigation.
