Accident Sequence
The pilot was initiating takeoff on runway 13 at Aberdeen Municipal Airport in Aberdeen, South Dakota. Upon reaching 55 miles per hour, the pilot rotated the aircraft. Immediately after rotation, the stall warning horn activated. The pilot then allowed the nosewheel to contact the runway again. Subsequently, the aircraft began to veer left and right before departing the right side of the runway and overturning.
Post-Accident Examination
Investigators found shredded remains of the nosewheel tire on the runway surface. Additionally, impressions consistent with tire rim contact were observed on the asphalt runway. These marks indicated that the tire rim had made contact with the pavement.
Tire History
According to the aircraft operator, the nosewheel tire had been installed on February 1, 1983. At the time of installation, the tachometer reading was 1963.47 hours. The difference between installation and the accident was 699 hours of operation. The tire casing was described as being in fair condition. An A&P mechanic noted that a patch found on the inside of the tire casing was a balance weight. However, there was no evidence that this balance patch contributed to the tire failure.
