As the helicopter market continues to grow, helicopter maintenance companies are also experiencing its boom. Although International Air Response is known for their fleet of Lockheed C-130s, IAR Technical Services is also a leading helicopter maintenance company. They specialize working on various Airbus models, Bell 206, and MD500 series helicopters.
Before companies execute a helicopter MRO, they have a maintenance checklist to follow. IAR is equipped with smooth-sailing operating procedures from basic maintenance activities to an intensive overhaul. To ensure that each helicopter’s projects are done within the aviation standards, here are the things they have to look after:
Before removing a single screw out of an Airbus or other helicopters, it’s important to perform an inspection first. MD500 Series has a different build with Airbus AS350, AS355, EC120, EC130, EC135, and EC145. This means that one method won’t work for all helicopter models. Interagency standards in terms of inspection apply here.
The Bell 206 also requires a different maintenance approach as a commercial and family flight helicopter. Since these three different lines of helicopter fleet differ in size, weight, and construction, there’s no one-size-fits-all maintenance solution; specialized technical training is required.
Upgrading an aircraft allows the helicopter to be converted with the latest technology. For example, the Airbus helicopters can have mid-life upgrades of glass cockpits and a brand new configuration. Take note that IAR has a type certificate for specific upgrades and retrofit services from Airbus, Bell, and MD Helicopters.
Like Bell helicopters, the MD 500 series is also a lightweight fleet for both civilian and military use. However, they have a different construction from Airbus both on the tail and the cabin.
Avionics and retrofitting
One the most crucial part of flying a helicopter is ensuring that avionics and wirings are all in top shape. For example, when dealing with Bell 206 helicopters, it’s important to check its chip detecting-powered transmission and collective mounted-throttle. Meanwhile, on Airbus, aircraft experts painstakingly handle its FADEC-equipped Safran Arriel 2C engines.
On the other hand, the MD 500 series helicopters have a fail-safe design and a three-dimensional truss-type structure. This is unique with the first two helicopters. It’s important that the maintenance provider is skilled and certified to perform retrofitting efforts.
Another thing to consider here is the fit-for-purpose retrofitting. If an Airbus, Bell, or MD helicopter owner wishes to tailor the aircraft for a specific use, say TV production, another set of skills is required here.
IAR’s goal in helicopter maintenance is basic: excellent flight and safety. When these two aspects are followed, the helicopter MRO process is surely done well.
Turbine engine power check
Turbine engine power checks are important as it dictates the ability of a helicopter to take flight. The turbine engines used in helicopters are way different than the one used in commercial airplanes. And if that’s not enough for maintenance challenge, each turbine engine will vary depending on who produced the aircraft.
Both the Bell 206 and a few of Airbus helicopter series are powered by Safran turbines while the MD500 series boasts Rolls-Royce turbine engines. During the helicopter MRO process, all these turbines are checked against the manufacturer’s standards.
