On September 15, 2012, about 1200 eastern daylight time, an Aerospatiale AS 355F1, N58020, operated by Analar Corporation, was substantially damaged when it impacted terrain following an in-flight separation near West Windsor, New Jersey.
The NTSB report describes following situation:
“During cruise flight, witnesses on the ground reported hearing a grinding or popping noise, which was followed by the separation of the yellow main rotor blade.”
The NTSB determines the probable cause to be:
“The disconnection of the upper rod end from the fore/aft servo due to severely worn threads, which resulted in a loss of control and separation of the main rotor blade during cruise flight.”
The iwi reconstruction resulted a flightpath corresponding with the provided radar-data of the helicopter. This was reconstructed based on three witness interviews. In addition, the observation from one of the witnesses, that the helicopter lost one of its main-rotor blades, could be confirmed, as some rotor debris were found 780 feet away from the main wreckage.
