On a helicopter, like any aircraft, there are certain parts that are more important than others. As such, you may find yourself buying the same parts more often than expected. In this blog, we will discuss, in no particular order, the nine most commonly purchased helicopter parts and components.
1. Arriel 1 and 2 Engine Modules
This may seem obvious, but the engine module is an important part of any helicopter. It is critical to the successful performance and safety of the aircraft, so it is in constant use. As such, it wears out over time and is in constant need of maintenance and replacement. Engine modules for the Arriel 1 and 2, part of Safran’s Arriel family of helicopters, are the most frequently ordered.
2. Cross Beam
The cross beam is the part that connects the entire helicopter assembly to the rotor blades. As such, it’s no surprise that this part is frequently purchased. Regular maintenance of the cross beam is an important aspect of safe travel.
3. AVA (Anti-Vibration Assembly)
The anti-vibration assembly is a part that secures the main rotor to the fuselage. In addition to this, it is used to filter vibrations between the fuselage and rotor. Because it is so frequently exposed to intense vibration, it needs to be maintained, repaired, and replaced relatively frequently.
4. Bevel Reduction Gearbox
The bevel reduction gearbox is among the most common parts on helicopters and other rotorcraft. It is used in both the main and tail rotor gearboxes, where it is responsible for driving the rotors themselves. This is perhaps the most important part needed to keep your aircraft in flight, so there’s no wonder why these parts are purchased often.
5. Tail Rotor Spider
The tail rotor spider is a part responsible for holding the tail rotor onto the rest of the helicopter. If this part gets worn out and is not replaced, it can fail, posing the risk of your tail rotor flying off the helicopter during flight.
This part is a gear train that consists of two or more gears that rotate to interact with one another. As the epicyclic is the helicopter’s primary source of vibration, it requires regular repair and must be replaced more often than other parts.
The swashplate, another area of frequent vibration, is responsible for the tilting of the main rotor to assist with controlling the direction of the helicopter. If the swashplate were to fail, the rotor could stop spinning, causing the helicopter to become nearly impossible to steer.
8. Oil Pump
Just like in a car, if the helicopter’s oil pump fails, it can cause catastrophic damage to the aircraft’s internal machinery. Even in the best case scenario, the helicopter’s performance capabilities will be significantly worsened.
9. Tail Rotor Gearbox
The final part on this list is the tail rotor gearbox. This part is extremely common and is responsible for keeping your tail rotor spinning. Without a properly functioning tail rotor, steering the helicopter is not possible. As the tail rotor gearbox has such a critical role within the helicopter, it is constantly in high demand.
