Beginning in 1984, F28 F and 280FX helicopters were produced with the gross
weight limitation of 2600 pounds.
Enstroms are relatively quiet helicopters due to the installation of the turbo-
charger, and the slow turning main and tail rotors. They can be equipped with an
optional secondary muffler that lowers the noise signature significantly.
All Enstrom helicopters feature a three bladed, fully articulated main rotor system
which has over 4,000,000 flight hours and which has never had a catastrophic
failure or thrown a blade. The tail rotor is two bladed and completely unblocked
for exceptional effectiveness. Due to the high inertia rotor design, the helicopter
possesses out-standing auto-rotational capabilities.
In addition to being a versatile and crashworthy helicopter, the 280FX and F28 F
helicopters were designed to be procured and operated for minimum costs. The
helicopter does not require hydraulic boost or stability augmentation systems.
The limited number of fatigue critical parts, the long overhaul intervals, and the
low hour/flight ratio resulting from high reliability and easy maintenance combine
to yield low operation and support costs.
