EASA AD 2011-0168R1

Lights — Instrument Lighting Display Brightness — Modification

EASA Airworthiness Directive 2011-0168R1 is a regulatory update addressing instrument lighting display brightness issues on Airbus Helicopters Deutschland GmbH EC 135, EC 635, and MBB-BK117 C-2 helicopters equipped with optional night vision goggle (NVG) systems. The directive mandates modifications to the electrical wiring in the overhead panel to prevent overheating of diodes in the NVG system, which can cause sudden maximum brightness of critical flight displays. This AD ensures continued safe operation by correcting a lighting system fault that could impair pilot visibility.
