Tailboom
The tailboom consists of the structural and aerodynamic elements aft of the aft fuselage, excluding the stabilizers. It supports the anti-torque control and its drivetrain, and it also supports the stabilizers. It has the components that follow:
Tailboom assembly
The tailboom assembly is an aluminum sheet tubular assembly with internal bulkheads, a machined aluminum tail rotor gearbox and empennage support. The tail rotor driveshaft assemblies and bearings are located on top of the tailboom. Supports for the tail rotor driveshaft bearings are located on top of the tailboom. The anti-torque control cables are routed inside of it. The tailboom assembly is attached to the truss assembly with four inboard bolts.
Forward driveshaft cover
The forward driveshaft cover is an aluminum sheet assembly. It protects and gives access to the driveshaft and its bearings. It also provides the aerodynamic shape of the helicopter. It is located on top at the forward end of the tailboom. It is attached to the structure with quarter-turn fasteners.
Mid driveshaft cover
The mid driveshaft cover is an aluminum sheet assembly. It protects and gives access to the driveshaft and its bearings. It also provides the aerodynamic shape of the helicopter. It is located on top in the middle of the tailboom. It is attached to the structure with quarter-turn fasteners.
Aft driveshaft cover
The aft driveshaft cover is an aluminum sheet assembly. It protects and gives access to the driveshaft and its bearings. It also provides the aerodynamic shape of the helicopter. It is located on top at the aft end of the tailboom. It is attached to the structure with quarter-turn fasteners.
Tail rotor gearbox and empennage support cover
The tail rotor gearbox and empennage support cover is made from an aluminum sheet. It protects and gives access to the anti-torque controls. It is located on the bottom of the tail rotor gearbox and empennage support. It is attached to the structure with screws.
Forward tailboom access panel
The forward tailboom access panel is made from an aluminum sheet. It protects and gives access to the tailboom internal components. It provides the aerodynamic shape and structural integrity of the tailboom. It is located on the bottom at the forward end of the tailboom. It is attached to the structure with screws.
Aft tailboom access panel
The aft tailboom access panel is made from an aluminum sheet. It protects and gives access to the tailboom internal components. It provides the aerodynamic shape and structural integrity of the tailboom. It is located on the bottom in the middle of the tailboom. It is attached to the structure with screws.
