CARS & AIRS modification for Eurocopter / Airbus EC135

The Cockpit Audio Recording System & Airborne Image Recording System fulfills the requirements of Civil Aviation Authority Safety Directive SD-2018/002 which arose as a consequence of AAIB safety recommendations 2015-032, 033, 035 following the tragic EC135 T2+ accident at Clutha, Glasgow, 2013 in which ten people were killed. Subsequently, EASA Safety Information Bulletin 2019-15R1 Flight Recorders on Small Rotorcraft, has recognised the need to promote installation of flight recorders in order to maximise the safety enhancement for the global aviation system.

This EC135 modification installs a crash protected Cockpit Audio Recording System (CARS) and Airborne Image Recording System (AIRS) to the Airbus Helicopters EC135. The system records cockpit audio in accordance with EUROCAE ED-155 Part I and imagery in accordance with ‘Class C’ of EUROCAE ED-155 Part III. This system can be installed on any CS-27 rotorcraft subject to survey & contract.

The EC135 modification is available as either:

  • One camera system which records the forward instrument panel
