What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Narrative: arthur blaylock untied and turned the rotor blade on N121NH 90 degrees. When he released the rotor it dipped down on the other side of the aircraft into the plane of rotation of the rotor of another aircraft (N123NH) which was running at idle on the next parking pad. Minor damage to both aircraft ensued. Mr. Blaylocks actions were contrary to safe operating practices and his company operations manual.
