Incident at 40 NM E of Vulcan, AB

Summary

1999-08-19: The pilot of C-GPHE, a Hughes 369E, had just refuelled and was conducting sling operations with a seismic team 40 miles east of Vulcan. He was picking up bags of equipment using a 50 foot lanyard and had picked up the third bag and was moving toward the fourth bag when he heard the low rotor warning. He did not have time to jettison the load prior to ground impact. After landing, the pilot noticed the engine TOT was high, so he turned off the battery switch and exited the helicopter. As he moved around the a/c he noticed that there was a fire in the tailpipe. The fire extinguished itself. The pilot was not injured, but the helicopter is substantially damaged. Investigators from the TSB are enroute to examine the machine and more information may be available. OPI - System Safety UPDATE TSB reported that the examination determined that the engine (Allison 320-2508) gas producer and nosels had been severely damaged. Analysis of the parts by the TSB Engineering Branch concluded that the blade tip damage was a result of over temperature operation. Testing of the TOT (Turbine Outlet Temperature) system determined that the guage was a erroneously indicating a much lower than actual temperature.
