re: Helicopter Crash in Lafourche Parish

If the engine seizes there is a piece of equipment called the freewheeling unit which is basically a clutch that will disconnect the engine and its driveshaft from the transmission, allowing the transmission to rotate or freewheel which allows the main rotor to spin free allowing the pilot the chance to perform an autorotation. Now its possible the freewheling unit could have failed not allowing the rotor system to freewheel but the existing rotational forces would probably cause the driveshaft to fail catastrophically and still allow the rotor system to rotate freely. I'm no expert but I do have 25 years of helicopter maintenance with 22 years on the Bell 407.

Ill try to answer any questions y'all might have.
