IL 429-15-01: Rogerson Kratos display unit anomaly (27 May 2015)
Bell Helicopter has received two reports of Display Units (DU) manufactured by Rogerson Kratos that went blank following some display anomalies (horizontal colored lines) with a very limited amount of smoke and burn smell in the cockpit. Our investigation has shown that this phenomenon is the result of a capacitor failure inside the DU.
