On 6 January 2007, a TL-2000 Sting Sport ultralight aircraft, registered 24-3770, was found to have impacted the ground approximately 30 km north west of Goulburn. The aircraft was fitted with a Rotax 912 ULS Engine. The engine disassembly and inspection was conducted by a Rotax engine specialist at the request of the NSW police, during which, the crankshaft was found to have fractured. Recreational Aviation Australia subsequently requested the assistance of the Australian Transport Safety Bureau in conducting technical analysis of the crankshaft. That analysis found no indications that would have prematurely initiated failure or have been detrimental to the fatigue life of the crankshaft.
