Airbus Helicopters
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Helicopters Model AS332C, AS332C1, AS332L, AS332L1, and AS332L2 helicopters. This AD was prompted by reports of a crack in the front upper hoist attachment fitting. This AD requires inspecting each affected hoist attachment fitting (fitting) and depending on the results, removing any cracked fitting from service and reporting information. This AD also prohibits installing an affected fitting unless the required actions are accomplished, as specified in a European Union Aviation Safety Agency (EASA) AD, which is incorporated by reference.

Hoffmann GmbH & Co. KG Propellers
The FAA is superseding Airworthiness Directive (AD) 2021-23-17 for all Hoffmann GmbH & Co. KG (Hoffmann) model HO-V 72 propellers. AD 2021-23-17 required amending the existing aircraft flight manual (AFM) by inserting abnormal propeller vibration instructions, visual inspection and non-destructive test (NDT) inspection of the propeller hub and, depending on the results of the inspections, replacement of the propeller hub with a part eligible for installation. Since the FAA issued AD 2021-23-17, further investigation by the manufacturer revealed that cracks found on propeller hubs likely resulted from propeller blade retention nuts that were not tightened using published service information during blade installation. This AD is prompted by reports of cracks at different positions on two affected propeller hubs. This AD retains the required actions of AD 2021-23-17. This AD also requires a maintenance records review and, depending on the results of the maintenance records review, tightening of each propeller blade retention nut to specific torque values. Depending on the results of the maintenance records review, this AD requires physically inspecting the propeller blade for shake. If any axial play is detected during the performance of the inspection, this AD requires the removal of the propeller from service and the performance of an NDT inspection of the propeller hub, and depending on the NDT inspection results, replacement of the propeller hub with a part eligible for installation. The FAA is issuing this AD to address the unsafe condition on these products.

Viking Air Limited (Type Certificate Previously Held by Bombardier Inc. and de Havilland, Inc.)
The FAA is adopting a new airworthiness directive (AD) for all Viking Air Limited (Viking) (type certificate previously held by Bombardier Inc. and de Havilland, Inc.) Model DHC-3 airplanes. This AD was prompted by a recent investigation of a Viking Model DHC-3 airplane where the lock ring of the stabilizer actuator was found missing. This AD requires a visual inspection of the stabilizer actuator to confirm that the stabilizer actuator lock ring is present, correctly seated in the groove in the upper housing, and engaged in the clamp nut, applicable corrective actions, and application of a torque seal. This AD also requires sending the inspection results to the FAA. The FAA is issuing this AD to address the unsafe condition on these products.
