Landing and Incident
A Cessna 182R pilot conducted a straight-in visual approach to runway 09. Approximately 2 miles from the runway, the pilot lowered 10 degrees of flaps and established an airspeed of 80 knots. At about 1 mile out, flaps were increased to 20 degrees while maintaining 80 knots. Half a mile from the runway, the pilot lowered flaps to 30 degrees and reduced speed to between 70 and 80 knots before initiating the flare.
Upon touchdown of the nose wheel, a loud chattering noise occurred accompanied by intense vibration. The nose wheel then bounced twice on the pavement. After the third bounce, the propeller made contact with the runway surface. Post-landing inspection revealed a zigzag black scuff mark slightly left of the runway centerline, along with two gouges in the asphalt perpendicular to the scuff mark's track.
Post-Accident Examination
Examination of the damaged nose wheel fracture surfaces showed characteristics typical of overstress separation. All bearing components were covered with an abundant amount of lubricant and exhibited no heat tinting. No evidence of fatigue cracking was found on the fracture faces.
