Eurocopter France Model SA-365N and SA-365N1 Helicopters
This amendment adopts a new airworthiness directive (AD) for the specified Eurocopter France (Eurocopter) model helicopters. This action requires you to disconnect the high level fuel switches in the fuel tanks on the affected helicopters. In addition, for helicopters without a crossfeed between the fuel filler necks, you must install a placard on or near the center console fuel panel that specifies fuel transfer limitations. This amendment is prompted by a report that a high level fuel switch probe unit installed on a Model SA-365N helicopter in the rear (right-hand) auxiliary fuel tank group separated, causing damage to the insulation of the electrical wires which supply electrical power to the high level indicator light on the fuel control panel during a fuel transfer. This condition, if not corrected, could lead to exposure of the electrical wires, which could lead to a short circuit and activation of the indicator light without the high fuel level actually being reached. Additionally, a short circuit could become an ignition source inside the fuel tank, and result in a fuel tank explosion and subsequent loss of control of the helicopter.

Agusta S.p.A. Model A109A, A109A II, A109C, and A109K2 Helicopters
This amendment supersedes an existing emergency airworthiness directive (EAD) for the specified Agusta S.p.A. (Agusta) model helicopters. That EAD currently requires inspecting the main rotor scissor fitting assembly to determine if there are 2 washers installed under the head of each main rotor scissor fitting assembly fixing bolt (fixing bolt). If there are not 2 washers installed under the head of each fixing bolt, that EAD requires replacing each fixing bolt and installing 2 washers under the head of each fixing bolt. This superseding airworthiness directive (AD) is prompted by the determination that a wrong part number (P/N) for the main rotor scissor fitting assembly was listed in the EAD. This AD retains the requirements of the EAD and corrects a P/N for the main rotor scissor fitting assembly. The actions specified by this AD are intended to prevent a crack in a fixing bolt, failure of a fixing bolt, and subsequent loss of control of the helicopter.

Eurocopter France (ECF) Model EC120B Helicopters
This amendment adopts a new airworthiness directive (AD) for ECF Model EC120B helicopters. This action requires inserting an emergency procedure appendix from an ECF Emergency Alert Service Bulletin into the Rotorcraft Flight Manual (RFM). This action also requires modifying the emergency switch electrical wiring and performing tests to ensure correct operation of the emergency switch. This action also requires removing the emergency procedure appendix from the RFM after modifying the emergency switch electrical wiring and performing tests to ensure correct operation. This amendment is prompted by the discovery that simultaneously setting the emergency switch to the low position "CUT-OFF" and the generator (GENE) pushbutton to "OFF" position caused the starter-generator to restart. Investigation revealed that cross-wiring at the emergency switch caused this malfunction. This condition, if not corrected, could lead to the inability to isolate electrical equipment during an emergency, creating the risk of an uncontrolled electrical fire and subsequent loss of control of the helicopter.

This amendment adopts a new airworthiness directive (AD) for the specified Agusta S.p.A. (Agusta) helicopters with a certain tail rotor special hub plug (hub plug) installed. This action requires a one-time inspection to determine the tightening torque value of the hub plug, and depending on the inspection results, replacing certain parts or disassembling the tail rotor hub and blades assembly and inspecting for damage. If the tightening torque value is between 600 kgcm and 700 kgcm, the lock washer and o-ring must be replaced with airworthy parts, and no further action is required. If the tightening torque value is greater than 700 kgcm, the hub plug must be replaced with an airworthy part. Torque the new hub plug to the specified tightening torque between 600 and 700 kgcm. If the tightening torque value of the hub plug is less than 600 kgcm, the tail rotor hub and blades assembly must be disassembled and inspected for damage. If a part is found that is outside allowable damage tolerances, that part must be replaced with an airworthy part. This amendment is prompted by the discovery that a wrong tightening torque value for the hub plug was contained in a revision to the helicopter maintenance manual. The actions specified in this AD are intended to detect an improperly torqued hub plug that could lead to tail rotor failure and subsequent loss of control of the helicopter.
