From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

(-23) On November 9, 2007 in Morristown Tennessee (mor) a Bell helicopter BHT-407 with a registration number 555BH was being operated by registered owner logan & kanawha coal company LLC. The pilot, a company pilot for 25 years, was flying the ceo and his wife. Upon landing the pilot left the helicopter at flight idle, a common practice according to the ceo, exited the aircraft and assisted in carrying luggage. When the pilot returned to the helicopter he was struck in the face by two of the four main rotor blades. Investigation revealed that no friction was applied to the cyclic friction lock and the hydraulic switch was in the off position. The ceo stated that the pilot often shut down the hydraulics upon landing. The wind was approximately 10 knots quartering tail wind and the aircraft was sitting on the tarmac with a 3 degree slope. The helicopter was equipped with low skids. Further investigation revealed the rotor blades could have dipped as low as 67 inches from the surface in front of the helicopter. The pilot was 70 inches tall.
