Summary
We propose to supersede Airworthiness Directive (AD) 2009-25- 07 for Airbus Helicopters Model EC120B helicopters. AD 2009-25-07 currently requires amending the rotorcraft flight manual supplement (RFMS) and pre-flight checking the emergency flotation gear before each flight over water. Since we issued AD 2009-25-07, Airbus Helicopters developed a terminating action and identified an additional part- numbered emergency floatation gear part with the unsafe condition. This proposed AD would retain the requirements of AD 2009-25-07, expand the applicability, and add a terminating action for the repetitive inspections. The actions of this proposed AD are intended to correct the unsafe condition on these helicopters.
