Read the full NTSB narrative
The helicopter was substantially damaged during a forced landing to a swamp after a total loss of engine power. The purpose of the flight was to spray for mosquito control. Inspection of the engine revealed that the compressor coupling shaft to the spur adapter gear shaft had damaged splines on the turbine driven end of the coupling shaft. Examination of the turbine end of the exhaust collector revealed that the circumferential weld joining the mounting flange to the bifurcated duct was non-uniform, discontinuous, and displayed a heat tint on both sides. Closer examination revealed places where the duct material; adjacent to the weld was slightly buckled and displayed indications of being impacted. The exhaust collector was dimensionally checked on a co-ordinate measuring machine (CMM). The CMM indicated that the flatness of the attaching flange for the pilot diameter displayed localized variation. As the print specifies that the centerline of the collector is established from the turbine pilot diameter and its attaching flange surface, their discrepancies resulted in a run out error on the gearbox pilot diameter.
