NTSB Narrative Summary Released at Completion of Accident
On December 16, 2006, at around 17:00 local time, the pilot of a MACAIR SAAB 340B, registration number VH-UYA, observed a interstage turbine temperature warning light during takeoff roll. The pilot aborted the takeoff and shut down the No. 2 engine, a General Electric CT7-9B turboshaft. The pilot noted that the ITT shot up to 960 to 970 deg for a period of about 2 seconds. As the engine spooled down, the pilot noted an audible whine/rumble from the engine until rotation ceased. The aircraft returned to blocks, and a start was attempted on the No. 2 engine. The start hung at 40% Ng, and was aborted. On-site inspection revealed one stage 4 power turbine blade had separated near the root, and others with missing tip shrouds. The engine was sent to GEES Strother for investigation.
As a result of the failure, the Australian Transport Safety Bureau initiated an investigation into the incident. The ATSB requested an Accredited Representative from United States in accordance with ICAO Annex 13 to assist in communications with the engine manufacturer, General Electric, and to attend the engine examine at the manufacturer's facilities. The Federal Aviation Administration provided oversight of the engine examine.
The investigation is under the jurisdiction of the government of Australia. Further information pertaining to this accident may be obtained from:
