The NTSB's narrative final · quoted from the NTSB record
The flight had departed from an island after completing a mosquito control inspection. The pilot said he was at a cruise setting of '23 inches [manifold] plus 2800 rpm' and at an altitude of 200 feet above the water, when the engine started 'missing' and 'failed to develop enough power to maintain flight.' The engine sputtered and regained full power. The pilot was setting up for an autorotation with a forward airspeed of 50 knots. The pilot further said he had 'split the needles,' and had set the engine rpm at 2,000. When he decelerated the helicopter at 50 feet above the water, the engine came back on line. The pilot then 'joined' the needles and established an attitude to continue flight when the landing skid contacted the water. A test run was performed on the engine. Due to damage to the magneto's and the ignition harness, these components had to be repaired prior to running the engine. The test run of the engine revealed no discrepancies at all power sittings.
