Testing conducted by HNL to enable like-for-like comparison showed that the 407HP was superior to the standard Bell 407 in the following ways:

  

• Heavy lifting: With its increased lifting capacity, the 407HP was able to lift and move heavier parts of the drill rig, thus reducing any need for disassembly.

 

• Fuel capacity: The 407HP was able to go out with more fuel than a standard Bell 407 whilst lifting similar loads, consequently saving the ferry time/costs to refuel.

 

• Internal load: Because of its ability to land with a heavier internal load, the 407HP was able to carry out a food resupply in one trip instead of two.

The 407HP is fitted with Honeywell’s HTS900 engine and is designed of operating in the hot and high environment of Papua New Guinea. Further, the light weight and high-performance capabilities of the engine allow power to increase while fuel consumption remains low. As an example, high altitude testing above 10,000 feet, has the aircraft lifting more than a standard B212 and close to double the standard 407. 

 

Eagle 407HP is torque-limited to around 10,500 feet compared to around 3,500 feet on a standard Bell 407 in Papua New Guinea. This ability of the HTS900 to supply the maximum allowed transmission horsepower up to 10,500 feet is key as to why the 407HP is a game changer.
