ESG: EASA approves STC for Electro Optical Systems for EC135 - 2016

ESG proves its capabilities as a leading aviation engineering company.

03.11. 2016


EASA has approved ESG’s new Supplemental Type Certificate “Installation of HD EOS on EC135”. The STC was developed by ESG’s EASA Part 21 J Design Organisation and covers the integration of the FLIR Systems StarSAFIRE 380-HD and StarSAFIRE 380-HDc products into EC135 helicopters. Through an extensive comprehensive flight test programme - including handling qualities, flight performance and functionality - it enables “CAT-A” operations, giving crews additional safety margins during takeoff and landing.
The modification is set up in a generic way and can be used with different types of EOS. Initially it will be used for the FLIR Systems Star SAFIRE 380-HD family, but with further modifications and extensions it could also be used with other types of EOS.

The Croatian Police, the initial customer of this installation, took delivery of the first modified helicopter in August this year. Further customers will receive their helicopters modified with new EOS in the coming months. 
In order to provide the best possible support to its customers, ESG has developed a set of STCs for operator workstations, a software-defined mission management system and a Trakka A800 search light for the EC135. The modular design allows low-risk modifications to the very special needs of HEMS and SAR operators, as well as police and other law enforcement operators.

ESG’s production organisation, in accordance with EASA Part 21 G, is capable of delivering STC integration kits that enable customers to perform integration through EASA Part 145 maintenance organisations. All fixed provisions and the removable parts – including the Electro Optical System - are delivered with EASA Form 1 and their associated installation documentation and manuals.


For fifty years, ESG has been one of Germany's leading companies for the development, integration and operation of complex, security-relevant, electronic and IT systems. ESG is an aviation engineering company in line with EASA Part 21G, EASA Part 21J and LBA Part 145 as well as an approved aviation company for aviation devices for the Bundeswehr. More than 1600 employees around the world provide logistics, system development, training, research and technology for military, government and industry customers.
