What the agency says
The FAA proposes to supersede Airworthiness Directive (AD) 2020-24-07, which applies to certain Airbus Helicopters Model AS350B3, EC130B4, and EC130T2 helicopters. AD 2020-24-07 requires modifying and inspecting the pilot's and co-pilot's throttle twist grip (twist grip) for proper operation. Since the FAA issued AD 2020-24-07, Airbus Helicopters developed another modification of the twist grip and additional corrective actions for helicopters already modified. This proposed AD was prompted by reports of the engine remaining in idle when the twist grip was turned from the "IDLE" mode to the "FLIGHT" mode. This proposed AD would retain the actions required by AD 2020-24- 07 and mandate an additional modification, which would constitute terminating action for the repetitive inspections. This proposed AD would also expand the helicopter applicability, propose additional requirements for certain helicopters, and would prohibit installing affected microswitches or an affected twist grip with the affected microswitch. The FAA is proposing this AD to address the unsafe condition on these products.
