The partial loss of engine power due to the failure of the magneto's internal timing during low-altitude maneuvering.

Read the full NTSB narrative

The helicopter experienced a loss in rotor rpm while maneuvering during a low-level wildlife survey. The commercial pilot then performed a forced landing to a field. Postaccident examination of the helicopter revealed that one of the engine magnetos had an internal timing, efficiency gap failure, which would have resulted in improper engine ignition timing and loss of engine power/rpm. Examination also revealed that the magneto distributer gear was loose and that the distributer gear bushing was flapping around.
