Owners and operators of all U.S.-registered Agusta A109E Power helicopters are being required to reduce their tail-rotor blade life limit, as well as reins ...

The tail rotor blades can pitch up and down to control the direction of the fuselage, similar to how the main rotor blades also alter their geometry to move the helicopter.

And the small tail rotor, perched vertically out on a boom behind the cabin, keeps the helicopter's body from spinning in the opposite direction as the main blades, but it also eats up about 30 ...

In a typical tail rotor, those spinning tail blades are connected mechanically to the aircraft’s engine. Physical components such as drive shafts, gear boxes, and couplings do the work to turn it.

Kyle Bailey, an aviation analyst, said it was "likely" that the separating rotor blades may have sliced off the aircraft’s tail boom. Such a scenario would have been unrecoverable, aviation ...
