EC 120/135

• European design • Latest technologies • Quiet operations

In order to match helicopter requirements in the next century. Eurocopter has produced its advanced EC 135 and EC 120 Colibri helicopters. Developed from the BO 108 technology demonstrator, the EC 135 is a high – tech successor to the MBB/Eurocopter BO 105, while the EC 120 is generally in the same class as Eurocopter’s own Ecureuil and Gazelle. It meets the Bell JetRanger and MD 500 series head on, and is likely to sell well.

Eurocopter considors all EC 135 prototypes to be pre – production prototypes. D-HECX was the first examo.

and is seen on its maiden fight


A Before the EC 135

Mcsscrschmitt-Bolkow-Blohm (MBB) flow the first example of its Allison-powered BO 108 on 15 October 1988. The design subsequently evolved into the EC 135.
