    8/6/02 | Free Lance-Star

    AP- Estes Park, CO - A helicopter crashed and killed its pilot while fighting a forest fire because its turbine engine overheated and partially melted... NTSB investigators were still trying to determine what caused the overheating... "Witnesses reported hearing a high-pitch whine and seeing rotor blades turning slowly, so we suspected a problem with the power train" said Arnold Scott, chief investigator for the Denver office of the NTSB. Investigators took the engine apart and founf that a part of it is just literally toast, just burned up, Scott said on 8/5/2002. The damage interrupted the transfer of power to the helicopter's rotor blades. The FAA investigators examined the maintenance records for the Aerospatiale SA-315B Lama helicopter which was owned by Geo-Seid of Fort Collins. The rebuilt engine on the 1978 helicopter had logged only about 200 hours of flying time. The crash killed the pilot Leonard G. Knight, 52 of Boulder.
