Unsafe condition
This AD was prompted by a report of a gap between the bolted assemblies under the attachment fittings of the main gearbox (MGB) suspension bars. The FAA is issuing this AD to prevent structural failure of the MGB attachment screws. The unsafe condition, if not addressed, could result in detachment of the MGB suspension bars with consequent loss of control of the helicopter.
