EASA Issues AD for EC135 Hub Shaft Cracks
The EASA has issued a new emergency Airworthiness Directive (AD) after further cracks were detected on the lower hub-shaft flange of two other Eurocopter EC135 light-twin helicopters. Repetitive preflight inspections are required and different from those described in a first emergency AD, issued in March. The initial inspections proved insufficient. The investigation is ongoing.
