Airworthiness Directives; Bombardier, Inc. Airplanes
We propose to adopt a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-102, -103, -106, -201, -202, -301, -311, and -315 airplanes. This proposed AD was prompted by fuel system reviews conducted by the manufacturer. This proposed AD would require revising the maintenance or inspection program to incorporate new limitations for fuel tank systems. We are proposing this AD to prevent potential ignition sources within the fuel system, which could result in a fuel tank explosion.

Airworthiness Directives; Airbus Helicopters Deutschland GmbH (Previously Eurocopter Deutschland GmbH) (Airbus Helicopters) Helicopters
We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Model EC135P1, EC135T1, EC135P2, EC135T2, EC135P2+, EC135T2+, and MBB-BK 117 C-2 helicopters. This proposed AD would require inspecting certain washers for movement and making appropriate repairs if the washers move. This proposed AD is prompted by play found between the Smart Electro Mechanical Actuator (SEMA) and the control rod during installation work on a helicopter. The proposed actions are intended to prevent loss of concerned control axis and subsequent loss of control of the helicopter.
Airworthiness Directives; Airbus Helicopters Deutschland GmbH (Previously Eurocopter Deutschland GmbH) (Airbus Helicopters) Helicopters
We propose to adopt a new airworthiness directive (AD) for Airbus Helicopters Model MBB-BK 117 C-2 helicopters with certain duplex trim actuators installed. This proposed AD would require repetitively inspecting the lateral and longitudinal trim actuator output levers for correct torque of the nuts. This proposed AD is prompted by a design review that the attachment screws can become lost under certain circumstances. The proposed actions are intended to prevent the loss of an attachment screw, which could result in movement of the output lever in an axial direction, contact of a bolt connecting the control rod to an output lever with the actuator housing, and subsequent loss of helicopter control.
Airworthiness Directives; Agusta S.p.A. Helicopters (Type Certificate Currently Held By AgustaWestland S.P.A) (AgustaWestland)
We propose to supersede airworthiness directive (AD) 2014-04- 14 for AgustaWestland Model A109S, AW109SP, A119, and AW119 MKII helicopters. AD 2014-04-14 currently requires removing certain rod end assemblies from service because of reports of fractures. Since we issued AD 2014-04-14, additional fractured rod end assemblies have been reported. This proposed AD would retain the requirements of AD 2014-04- 14 but expand the scope of applicable rod end assemblies. These proposed actions are intended to prevent failure of a rod end assembly, which could result in damage to the main rotor assembly and loss of control of the helicopter.
Airworthiness Directives; Pilatus Aircraft LTD. Airplanes
We propose to adopt a new airworthiness directive (AD) for all PILATUS AIRCRAFT LTD. Models PC-12, PC-12/45, PC-12/47, and PC-12/47E airplanes that would supersede AD 2012-26-16. This proposed AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as a need to incorporate new revisions into the Limitations section, Chapter 4, of the FAA-approved maintenance program (e.g., maintenance manual). We are issuing this proposed AD to require actions to address the unsafe condition on these products.
